800-850W Power Supplies Buying Guide and FAQ
This 800-850W Power Supplies range groups power supplies by output. Below are the common questions on what wattage suits your build.
Is a 800-850W power supply enough for my PC?
As a rough guide, 800 to 850W suits high-end cards such as an RTX 5070 Ti or 5080. Leaving some headroom keeps the unit cool and quiet.
What graphics card does a 800-850W PSU pair with?
Size the PSU around the graphics card, since it is the biggest draw. A 800-850W unit suits high-end cards, but always check the card maker's recommended wattage and that the PSU has the right power connectors, including the 12V-2x6 (12VHPWR) plug on newer Nvidia cards.
Should I get more wattage than I need?
A little headroom is sensible, because it keeps the PSU running cool, quiet and efficient, and leaves room for a future upgrade. There is no need to go wildly over the top, so pick a wattage that covers your parts with some margin and choose a reputable 80 Plus rated unit.
