Graphics cards (particularly from NVIDIA) seem to be moving in a direction that could very soon result in air conditioners/central cooling becoming a core requirement of running a high end PC. NVIDIA's latest Ada Lovelace GPUs have been confirmed to feature a TDP of 600W for some SKUs and even its upcoming RTX 3090 Ti custom graphics cards will sip close to 480W from the wall. A TDP of this level usually means that the PSU will need to be capable of handling power spikes in the range of 600-700W - which is mind-boggling.

We will go the following RTX 3090 Ti custom editions: the MSI RTX 3090 SUPRIM X, EVGA RTX 3090 Ti FTW Ultra and Colorful RTX 3090 Ti BattleAx Deluxe. All of these cards have been leaked courtesy of Videocardz (here and here). The one thing all three have in common is a TDP of at least 450W.
