How To Measure Your PC's Power Consumption
Modern computers have components that require lots of power and given that this all costs money, here's our guide to measuring how much energy your PC uses.
How Hot is Too Hot for PC Hardware?
With power limits of CPUs and graphics cards climbing ever higher, and news reports of chips hitting sky-high temperatures appearing almost weekly, it seems that now is as good a time as any to ask a simple question – just how hot is too hot for today's PC components?
Upcoming power consumption restrictions could limit sales of 8K TVs in the EU
The Rise of Power: Are CPUs and GPUs Becoming Too Energy Hungry?
Every few years new processors with ever-higher demands for energy are launched. Is 250W for a CPU too high? Should any GPU need 450W? Let's peel off the heatsinks to look at the truth behind power numbers.
Is AMD Zen 4 Too Hot for a Box Cooler? Ryzen 7600X + Wraith Spire Tested
A big point of contention with Zen 4 CPUs is that they run very hot. AMD says it's all by design, but how about we throw a basic air cooler to see if the 7600X throttles when under load?
Nvidia clarifies power supply requirements for RTX 40-series
The big picture: Since the announcement of Nvidia's RTX 40-series graphics cards, some consumers have been curious or even worried about their power supply, wondering if it can safely run a new GPU. Thankfully, Nvidia has cleared the air and reassured users regarding the power requirements for its cards.

25 Years Later: A Brief Analysis of GPU Processing Efficiency
The first 3D graphics cards appeared 25 years ago and since then their power and complexity have grown at a scale greater than any other microchip found in a PC. In going from one million to billions of transistors, smaller dies, and consuming more power, the capabilities of these behemoths is immeasurably greater, but what can we learn about efficiency?
Threadripper 3990X TRX40 VRM Torture Test feat. Asus ROG Zenith II Extreme Alpha
Today we're going to perform some AMD TRX40 motherboard VRM thermal testing using the powerful 64-core Threadripper 3990X. To apply load we're using Blender with the system running at stock and overclocked to 3.8 GHz. The typical power draw for this system is around 450 watts, but once overclocked we are hitting as much as 850 watts. Toasty!

Intel Core i9-9900K Re-Review: Performance unleashed, but also leashed
Today we're revisiting our original Core i9-9900K review and updating it with 95 watt TDP limited results, basically results based on the official Intel specification. For better context about this please read our opinion article from earlier this week titled "Do We Need to Re-Review the Core i9-9900K?".
