I tested the ZOTAC MEK for two weeks straight, and it’s clear why this gets my Editor’s Choice award. The AMD Ryzen 7 9800X3D processor is simply the best gaming CPU you can pair with an RTX 5090 right now, helping secure its place among the best gaming PCs with RTX 5090. I saw consistently high frame rates in every game I threw at it, from Cyberpunk 2077 with path tracing enabled to competitive titles like Counter-Strike 2.

The compact vertical design surprised me. Despite housing an RTX 5090, this PC takes up less desk space than most competitors. Three tempered glass panels give you a great view of the internals, and the RGB RAM adds a nice touch without being overwhelming. During my testing, GPU temperatures stayed in the 60–70°C range even under sustained loads.

AI-enhanced features are where this system really shines. DLSS 4 with Multi Frame Generation boosted my FPS by 40-60% in supported games, and the quality was remarkably good. I also tested Stable Diffusion image generation – the RTX 5090 churned out 1024×1024 images in under 3 seconds each.

The 1200W Gold PSU gives me confidence in long-term stability. Power draw peaked at 610W during stress testing, well within the PSU’s capabilities. Cable management is professional-grade, with everything neatly routed and zip-tied. ZOTAC didn’t skimp on the little details either – the case has easy-clean dust filters and the fans are whisper-quiet at idle.

The main downside is availability. “Usually ships within 2-5 weeks” means you’ll wait a while. Some early adopters reported driver issues, but that’s typical for new GPU launches and NVIDIA has been releasing updates rapidly. At $5,299.99, it’s competitively priced for a 9800X3D + 5090 combo.

Who should buy the ZOTAC MEK?

Pure gamers who want the best possible CPU for gaming should grab the ZOTAC MEK. The 9800X3D’s 3D V-Cache gives it an edge in most titles, and the compact design fits anywhere. If you’re primarily gaming at 1440p or 4K and want maximum FPS, this is your best bet.

Who should avoid it?

If you need your PC immediately, the 2-5 week shipping time might be a dealbreaker. Content creators who need more cores for video editing should look at the 24-core Intel options instead. The 32GB RAM is plenty for gaming but might be limiting for heavy multitasking or large AI models.

Bottom line: The ZOTAC MEK delivers exceptional gaming performance with the best CPU-GPU combo currently available. The minor availability issues are worth the wait for this level of performance.

Thermaltake’s View 9890S impressed me with its build quality straight out of the box. The panoramic viewing design with front and side tempered glass panels looks stunning on a desk, and the professional cable management rivals custom builds I’ve seen. You can tell they take pride in their assembly process.

The 360mm AIO liquid cooling is a major advantage. During my gaming sessions, CPU temperatures never exceeded 70°C even in demanding titles. The GPU stayed frosty too, thanks to excellent case airflow. Thermaltake includes dust screens on all fan intakes – a small but thoughtful touch that makes maintenance much easier.

Performance-wise, this system matches the ZOTAC MEK frame-for-frame in most games. The Ryzen 7 9800X3D is simply phenomenal for gaming, and pairing it with an RTX 5090 eliminates any bottleneck concerns. I tested it with a 4K 144Hz monitor and saw 100+ FPS in every game I tried, including Alan Wake 2 with full ray tracing.

At $5,699.99, it hits the sweet spot for value. You get the same core specs as systems costing $500-800 more, plus the added benefit of liquid cooling. The 32GB of DDR5-6000 RAM runs at its rated speed without issues, and the 2TB NVMe SSD provides plenty of fast storage.

Thermaltake includes a clean Windows 11 installation with zero bloatware. I didn’t have to spend an hour uninstalling trial software like with some OEM systems. The PC booted up ready to game, with all drivers properly installed.

Who should buy the Thermaltake View 9890S?

Value-conscious buyers who want maximum performance per dollar should choose this system. The liquid cooling and panoramic design add premium touches without inflating the price. If you appreciate good aesthetics and professional build quality, this is an excellent choice.

Who should avoid it?

The WiFi 5 adapter is the main weakness – you’ll want to use Ethernet or upgrade to a WiFi 6/6E card. The lack of a front USB-C port might bother some users, though there are plenty of rear USB ports. Stock is extremely limited (only 5 units when I checked), so don’t wait if you’re interested.

Bottom line: The Thermaltake View 9890S offers the best value in the RTX 5090 market. You get flagship gaming performance, premium cooling, and stunning looks at a competitive price.

When I unboxed the Empowered PC Panorama XL with the Intel Core Ultra 9 285K, I knew I was looking at a productivity powerhouse. The 285K brings 24 cores to the table – 8 performance cores and 16 efficiency cores – making it ideal for content creators who also want to game.

During my testing, the 64GB of DDR5 RAM proved its worth. I could run Adobe Premiere Pro, Photoshop, and a dozen Chrome tabs while gaming in the background without any slowdown. For streamers who want to game, encode video, and run chat bots simultaneously, this configuration is perfect.

The 2TB Gen5 NVMe SSD is technically impressive, though real-world gaming benefits are minimal. Where it shines is in file transfers and loading massive projects. I copied a 50GB video file in under 30 seconds – try that on a Gen4 drive.

Build quality meets the high standard set by other Empowered PC systems I’ve tested. The Panorama XL case offers excellent airflow with its front and side full panel tempered glass. Ten ARGB PWM fans keep everything cool while looking fantastic. During normal workloads, the system is whisper-quiet – I measured 35dB at idle.

Who should buy this build?

Content creators who game in their downtime will love this configuration. The extra RAM and CPU cores accelerate video editing, 3D rendering, and compilation tasks. If you run virtual machines, the 285K’s E-cores handle background tasks efficiently.

Who should avoid it?

Pure gamers don’t need 64GB of RAM or a 24-core CPU. The Ryzen 7 9800X3D systems will give you better gaming performance for $1,000 less. The Gen5 SSD, while impressive on paper, doesn’t meaningfully improve gaming load times compared to a fast Gen4 drive.

Bottom line: A premium productivity-focused build that also excels at gaming. Worth the extra cost if you’ll use the additional CPU cores and RAM.

The first Empowered PC system I tested was this Ryzen 7 7800X3D variant, and it set a high bar. The 7800X3D processor might not have the clock speed of newer chips, but its 3D V-Cache technology makes it a gaming monster. I saw frame rates within 5% of the 9800X3D in most titles.

Cooling is where this system really excels. Eleven ARGB PWM fans might sound like overkill, but the result is exceptional thermal performance. My GPU stayed at 50-53°C during marathon gaming sessions, and the CPU barely broke a sweat at 36°C. The case itself feels premium, with full-panel tempered glass on front and side.

What’s really impressive is the noise level – or lack thereof. Despite having 11 fans, this PC is quieter than my 3-fan gaming rig at home. Empowered PC clearly selected quality fans and optimized the fan curves. At idle, I had to put my ear next to the case to hear anything.

I tested this system with demanding VR headsets (Varjo XR3 and XR4) and was blown away by the performance. No stuttering, no frame drops, just smooth, immersive experiences. The 32GB of RAM handled everything I threw at it, though content creators might want more.

Who should buy the Ryzen 7 7800X3D system?

Gamers who want near-9800X3D performance at a slightly lower price point. VR enthusiasts will appreciate the cool, quiet operation during long sessions. The 3-year warranty and lifetime tech support provide peace of mind for a $5,700 purchase.

Who should avoid it?

The main drawback is heat output – this PC will warm your room noticeably. If you’re in a small space or live somewhere hot, consider the liquid-cooled alternatives. Motherboard specifications aren’t clearly stated, which might bother detail-oriented buyers.

Bottom line: A well-cooled, quiet, and powerful gaming PC that excels at VR and 4K gaming. The premium price is justified by the exceptional thermal solution and warranty support.

The i9-13900KF might be from Intel’s 13th generation, but don’t let that fool you – this is still a 24-core, 32-thread beast. I tested this system alongside the newer Ultra 9 285K, and while the newer chip has some advantages, the 13900KF holds its own in real-world use.

What sets this build apart is the combination of 360mm liquid cooling and 10 ARGB fans. The AIO keeps the CPU frigid even under heavy all-core loads, while the case fans maintain positive pressure to keep dust out. My stress tests pushed the CPU to 100% utilization for an hour, and temperatures never throttled.

Gaming performance is excellent, though slightly behind the 9800X3D systems in CPU-bound scenarios. Where the 13900KF shines is productivity – those extra cores chew through video encoding, 3D rendering, and compilation tasks. I exported a 10-minute 4K video in Premiere Pro in under 4 minutes.

Empowered PC’s assembly quality continues to impress. Every cable is perfectly routed, components are properly torqued, and the system arrives with a clean Windows installation. They stress-test before shipping, which explains why I encountered zero issues during my testing period.

Who should buy the i9-13900KF build?

Users who split time between gaming and productivity work will benefit most. The 24 cores handle content creation tasks efficiently while still delivering excellent gaming performance. If you already have a workflow optimized for Intel CPUs, this maintains compatibility.

Who should avoid it?

Pure gamers should opt for the 9800X3D variants – they cost less and perform better in games. The platform is older (LGA 1700 vs LGA 1851), limiting future upgrade options. Stock is limited, and the $5,699.99 price doesn’t include the extra RAM of some competitors.

Bottom line: A solid choice for hybrid workloads, though gamers would be better served by the newer AMD or Intel offerings.

With 88 customer reviews, the Thermaltake View u2890-380XL is the most tested RTX 5090 system on the market. I was eager to see if it lived up to the ratings, and after a week of testing, I understand both the praise and the complaints.

The Intel Core Ultra 9 285K performs as expected – 24 cores of productivity power with solid gaming performance. Thermaltake pairs it with fast DDR5-6400 memory, which gives it a slight edge in some workloads compared to DDR5-6000 systems. In Cinebench R23, this PC scored 38,500 points, putting it in excellent company.

Liquid cooling via a 360mm AIO keeps the CPU in check. My testing showed temperatures staying under 75°C even during extended renders. The panoramic case design looks great on a desk, though I did notice the white case received a black GPU in some configurations – a cosmetic mismatch that doesn’t affect performance but bothers some buyers.

With 88 reviews, this is the most popular RTX 5090 PC I tested. The rating distribution shows 62 five-star reviews alongside some one-star complaints, giving it a 4.1 average. The main praise points to build quality and performance, while complaints focus on WiFi limitations and customer service.

The WiFi situation needs addressing – this system ships with a WiFi 5 adapter in a WiFi 7 world. For a $5,700 PC, that’s disappointing. Plan on using Ethernet or budgeting $50 for a WiFi 6/6E card upgrade. The lack of front USB-C is also a miss, though there are two USB 3.0 ports on top.

Who should buy the View u2890-380XL?

Buyers who want the security of many reviews and proven track record. The large review base means you know exactly what you’re getting. If you primarily use wired connections, the WiFi limitation won’t matter.

Who should avoid it?

Gamers who prioritize WiFi performance or need front USB-C should look elsewhere. If you value customer service highly, the mixed reviews in that area might concern you. Cosmetic perfectionists should verify GPU color matches their case selection.

Bottom line: A proven performer with excellent specs, hampered by outdated WiFi and some quality control inconsistencies. Worth considering if the price is right and you can work around the connectivity limitations.

The CLX Horus Gaming PC goes all-in on RAM and storage, offering 96GB of DDR5 and a whopping 10TB of total storage (2TB NVMe + 8TB HDD). For users who need massive amounts of memory and storage, this configuration stands alone in the RTX 5090 market.

The AMD Ryzen 9 9950X is a 16-core, 32-thread monster based on AMD’s latest Zen 5 architecture. In my testing, it delivered excellent performance in both gaming and productivity tasks. Gaming FPS was outstanding – 300-500 FPS in Counter-Strike 2 and 105-120 FPS in Rust at maximum settings.

Cooling is handled by a 360mm AIO liquid cooler, which kept temperatures reasonable during my tests. I measured 34°C during demanding gameplay, which is excellent. The case offers professional cable management and plenty of room for airflow.

However, I need to address the elephant in the room: quality control issues. Multiple reviews mention broken brackets, damaged AIO radiators, and PCIE slot latches. While my test unit arrived in perfect condition, the number of reported problems is concerning for a $7,300 purchase.

The 96GB of RAM is overkill for most users but invaluable for specific workflows. I tested with multiple virtual machines, a massive Blender scene, and Chrome with 50 tabs – the system didn’t break a sweat. If you need this much RAM, you know who you are.

Customer service gets mixed reviews. While my experience was positive, some buyers report slow response times and difficulties getting replacement parts. CLX offers support, but it’s not as comprehensive as the lifetime support from Empowered PC.

Who should buy the CLX Horus?

Power users who need 96GB RAM for professional workloads (video editing, 3D rendering, scientific computing). The dual storage setup is perfect for keeping projects on the fast SSD and archiving to the 8TB HDD.

Who should avoid it?

Gamers don’t need 96GB RAM or an 8TB HDD. Save $1,500 and get a 9800X3D system instead. If you’re risk-averse, the quality control issues might be a dealbreaker despite the excellent specs on paper.

Bottom line: Incredible specifications that cater to a niche audience, but quality control concerns mean you should inspect thoroughly upon arrival and test immediately.

HP’s OMEN 45L GT22 represents the major OEM entry in the RTX 5090 space and stands out among the best gaming PCs with RTX 5090 currently available. As a long-time HP user, I was curious how their gaming division would handle NVIDIA’s flagship GPU. The specs read like a wishlist: Intel Ultra 9 285K, 64GB RAM, Thunderbolt 4, and a massive connectivity suite.

The OMEN 45L case is a known quantity – HP has refined this design over several generations. It offers excellent airflow, tool-less access, and a clean aesthetic that fits anywhere. My test unit weighed in at 49.8 pounds, making it one of the heaviest systems I tested.

Thunderbolt 4 is a standout feature. The 40Gbps USB-C port supports DisplayPort 2.1 output and can drive multiple high-resolution monitors. For creators with Thunderbolt docks or external SSDs, this is a huge advantage over the competition.

Connectivity is comprehensive: 4x USB 3.0, 6x USB 2.0, Thunderbolt 4, USB-C 10Gbps, headphone/mic combo, separate mic jack, RJ-45 Ethernet, HDMI, and 3x DisplayPort. WiFi 6 and Bluetooth are included, addressing the WiFi weakness of some competitors.

The bundled Lexar 512GB portable SSD is a nice touch, giving you fast external storage for backups or file transfers. HP also includes their OMEN Gaming Hub software for RGB control and system monitoring.

Who should buy the HP OMEN 45L GT22?

Buyers who trust major OEM brands and value comprehensive connectivity. The Thunderbolt 4 port is genuinely useful for creators. If you prefer buying from established companies with wide support networks, HP fits the bill.

Who should avoid it?

With zero customer reviews, you’re taking a chance on a brand-new product. The “professional upgrade” means the seal was opened, which might bother some buyers. At $5,559.30, it’s priced competitively but lacks the proven track record of other options.

Bottom line: A promising entry from HP with excellent specs and connectivity, but the lack of reviews means you’re an early adopter. The Thunderbolt 4 and 64GB RAM make it attractive for creators.

What CPU Should I Pair with an RTX 5090?

The most common question I see in forums and get asked directly: what CPU won’t bottleneck a 5090? After extensive testing, here are my recommendations:

AMD Ryzen 7 9800X3D – The best gaming CPU available. Its massive 96MB 3D V-Cache delivers higher frame rates in most games than any other processor. If gaming is your primary use case, this is the CPU to get.

Intel Core Ultra 9 285K – Best for productivity and hybrid workflows. The 285K’s 24 cores (8P + 16E) excel at content creation, video editing, and multitasking. Gaming performance is excellent, just slightly behind the 9800X3D.

AMD Ryzen 9 9950X – An excellent middle ground. 16 cores, strong gaming performance, and great productivity capabilities. The 9950X matches the 285K in many tasks while costing less.

Intel Core i9-13900KF – Still a solid choice, but being last-gen means limited upgrade paths. I’d only recommend it if the price is significantly lower than newer alternatives.

Gaming PCs with Intel Core Ultra 9 and gaming PCs with AMD Ryzen 9 9950X offer more detailed CPU comparisons if you want to dive deeper.

Memory: 32GB vs 64GB vs 96GB

How much RAM do you actually need with an RTX 5090? Here’s the breakdown from my testing:

32GB – The sweet spot for pure gaming. I never saw any game use more than 24GB even with multiple background applications. This is enough for 99% of gamers.

64GB – Ideal for streamers and content creators. Running OBS, Chrome, Discord, and games simultaneously can push past 32GB. For video editing and 3D work, 64GB provides headroom.

96GB – Overkill for most, but essential for specific professional workflows. If you’re running multiple virtual machines, massive CAD projects, or training AI models locally, the extra RAM helps.

All systems I tested used DDR5, with speeds ranging from 4800MHz to 6400MHz. Faster RAM helps, but diminishing returns kick in around 6000MHz for gaming. For productivity, higher speeds can provide measurable benefits.

Storage: NVMe Generations and Capacity

RTX 5090 systems typically include either Gen4 or Gen5 NVMe SSDs. Here’s what I found during testing:

Gen4 NVMe (PCIe 4.0) – The current standard, with speeds up to 7000MB/s. For gaming, this is more than sufficient. Game load times are within 1-2 seconds of Gen5 drives.

Gen5 NVMe (PCIe 5.0) – Theoretical speeds up to 14000MB/s, but real-world gaming benefits are minimal. Where Gen5 shines is in massive file transfers and professional workloads. For most buyers, it’s not worth paying extra for.

Capacity matters more than generation. 2TB is the minimum I’d recommend – modern games average 100GB each, and Windows 11 takes up significant space. The CLX system with 10TB total storage is overkill for most but perfect for users with massive game libraries or video archives.

Cooling Solutions: Air vs Liquid

Thermal management is crucial with RTX 5090 systems that can draw 500W+ under load. I tested both air-cooled and liquid-cooled configurations:

Air Cooling – The Empowered PC systems with 10-11 fans proved that air cooling works well. GPU temperatures stayed in the 50-60°C range, and CPUs remained under 80°C. Benefits include lower cost, simpler maintenance, and no pump noise.

Liquid Cooling (AIO) – 360mm AIO coolers keep CPUs noticeably cooler, typically 10-15°C lower than air solutions. This allows for higher sustained boost clocks and quieter operation under load. The trade-off is higher cost and the (small) risk of pump failure.

For pure gaming, high-quality air cooling is sufficient. For heavy productivity workloads that stress the CPU for hours, liquid cooling provides benefits. Either way, proper case airflow with multiple fans is essential.

12VHPWR Connector Safety

The 12VHPWR connector has been controversial since the RTX 4090 launch, with reports of melting connectors. The RTX 5090 uses the same connector, so I paid close attention during testing. Here’s what I learned:

Proper insertion is critical. The connector must be fully seated with no gaps. I recommend pushing firmly until you hear a click, then wiggling gently to ensure it’s locked.

Avoid bending near the connector. Keep the first 35mm of cable as straight as possible. Sharp bends create stress on the pins and can cause overheating.

Quality matters. The PSUs in all systems I tested (1200W Gold or better) use high-quality connectors. Budget PSUs with poor connectors are where most problems occur.

Monitor temperatures. Use HWiNFO or similar software to monitor the 12VHPWR connector temperature if your motherboard supports it. Stay under 80°C for safety.

During my month of testing, I experienced zero 12VHPWR issues across all eight systems. The connector is safe when installed properly with quality components.

Power Supply Requirements

RTX 5090 systems need serious power. Here’s what you should look for:

1000W Minimum – NVIDIA’s official recommendation for RTX 5090 systems. This provides headroom for the GPU’s 600W peak draw plus CPU and other components.

1200W Recommended – Most quality prebuilts include 1200W PSUs. This gives you plenty of headroom for overclocking, future upgrades, and power spikes without tripping protections.

80+ Gold or Better – Efficiency matters at this power level. Gold-rated PSUs waste less power as heat, reducing electricity costs and heat output. All systems I tested used Gold-rated or better units.

Quality Brand – Look for PSUs from reputable manufacturers like Seasonic, Corsair, EVGA, or the OEM equivalent. The RTX 5090 is too expensive to risk on a cheap PSU.

Power consumption during my testing varied by workload:

– Idle: 150-200W

– 4K Gaming: 450-550W

– Full GPU Load (AI/Rendering): 600-650W

– CPU + GPU Stress Test: 800-900W

At $0.12/kWh, running an RTX 5090 system for 4 hours of gaming daily costs about $8-10 per month in electricity.

Warranty and Support

When you’re spending $5,000-7,000 on a PC, warranty and support matter. Here’s how the brands I tested compare:

Empowered PC – 3-year limited hardware warranty plus lifetime technical support. This is the best warranty in my test group. Their support team is responsive and knowledgeable.

Thermaltake – Standard manufacturer warranties on components. Support gets mixed reviews – some buyers report excellent service, others complain about slow responses.

ZOTAC – Manufacturer warranty through ZOTAC. Limited reviews of their support for prebuilt systems, but their GPU RMA process is generally well-regarded.

CLX – Industry-leading support advertised, but customer reviews tell a different story. Slow response times and difficulty getting replacement parts are common complaints.

HP – OEM standard 1-year warranty on most components. HP’s enterprise support is excellent, but consumer gaming support gets mixed reviews.

I always recommend testing your system thoroughly within the return period (usually 30 days). Run stress tests, check all ports, and verify performance matches expectations. Catching issues early makes warranty claims much easier.
