That MSI GeForce RTX 5090 32G LIGHTNING Z Eats 1000W By Itself
Welcome to 2026 where PSUs that provide over two kilowatts of power are no longer rare. There are several models to choose from, including the Prime PX-2200 from Seasonic. It sports a 80 PLUS Platinum and a Cybenetics Platinum certification, which isn’t that important on a lowly 800W PSU but will save you a few bucks if you are using the full power of the Prime PX-2200.
For all it’s immense power and size, it’s 210 mm x 150 mm x 86 mm, at 2200W load the Prime PX-2200 produces a mere 45.8 dBA and the exhaust is only 60C. This beast does plug into a normal wall wart, no need to unplug your dryer, but it ships with a C19 mains cable which is heftier and more robust than the usual C15 cable which you probably have an embarrassingly large pile of.
As you would expect and KitGuru confirms, it ships with “enough cables to power a small nuclear station.“
