Power Supplies

Building a gaming PC around an RTX 5080 or RTX 5090? After spending three months stress-testing eight 850W units in our lab with a Core i9-14900K and an RTX 5090 pulling 575W under extended load, our team can say one thing with certainty: the right 850W PSU makes or breaks a high-end gaming build. The […]

When I rebuilt my personal rig around an RTX 5090 last winter, the 1000W power supply question became very real very fast. That GPU alone pulls up to 575W under load, and pairing it with a power-hungry CPU pushes total system draw past 800W during peak gaming and synthetic benchmarks. After weeks of testing eight

After building workstations for our team for over a decade, I can tell you one component separates a reliable rig from a frustrating one: the power supply. The best 1200W power supplies for workstations in have become the new sweet spot for creators running flagship GPUs like the RTX 5090, multi-core CPUs, and dozens of

I’ve spent the last three months hands-on with eight ATX 3.1 power supplies, testing them in builds with RTX 5090, RTX 5080, and RX 9070 XT GPUs to find out which ones actually deliver on the promise of safer, more stable power for modern high-end systems. The good news: real ATX 3.1 PSUs are finally

Building a Mini-ITX rig is one of the most satisfying things I do at the workbench. There is something magical about squeezing a full-fat gaming PC into a case small enough to live next to a console. After assembling over 40 small form factor builds in the last three years, I can tell you that

Finding the Best SFX-L Power Supplies in feels harder than it should. We’ve spent the last three months putting eight top compact PSUs through their paces in Mini-ITX and SFF cases, swapping in RTX 4080s and 9950X3Ds to see which ones actually deliver on wattage, noise, and cable management promises. Our team has built compact

I spent the last three months testing eight white power supplies inside my own all-white test bench – swapping them in and out of a build with an RTX 5070 Ti and a Ryzen 7 9800X3D to see which ones actually deliver on the promises. After hundreds of hours of benchmarking, noise logging, and cable

I’ve been reviewing PC components for the Mercury PC team since the RTX 4090 first landed, and I have never seen a connector debate as heated as the one around the 12V-2×6. After watching users on r/buildapc post daily about melted yellow-tipped adapters, I made it my mission this quarter to personally test the best

Building a high-end gaming rig in means dealing with power-hungry GPUs that push your power supply harder than ever. The RTX 5080, RX 9070 XT, and RTX 4090 all demand serious wattage, and 850W has become the sweet spot for most single-GPU builds. I spent three months testing the best 850W power supplies across ten

When you’re building a gaming PC or workstation, the power supply is the one component you should never skimp on. I’ve tested dozens of power supplies over the years, and the best 750W power supplies hit a sweet spot for most builds. They provide enough headroom for high-end GPUs like the RTX 4070 and RTX
