does the wattage requirement stack?

[franco.albertoni697]

if I have a 500w gpu and a 65 w cpu, is a 550w psu enough? or should I get one with a higer wattage

No current graphics card has a 500W power draw. Even the Radeon RX Vega 64 is only a 295W card. The GeForce GTX 1080 Ti is only a 250W card.

Don't confuse the "recommended power supply" wattage for a GPU with the power the GPU actually consumes. That recommended wattage is the manufacturer's guess at what you ought to get without know what other components you have, or the quality of the PSU.
