Say rtx3070 needs 220w from nvidia website

If i put it in 65w ryzen system , it should still have a lot of headroom left?

Btw Its a decent corsair tx550m 80gold

Is the PSU new?

Do you have visions of changing to a video card that draws considerably more power?

What else is connected? Hard drives and fans and RAM sticks don't draw much..maybe under 50 watts total.

Are you easily worried or prone to use the phrase "future proof"?

It was new using for 4 yrs
1HDD, 1 nvme, 1 wireless lan, cpu fan only
Or may be 3 more 12cm fans in future
I'd guess the specific items you just listed total 40 to 60 watts?

But I have absolutely no idea if that 220 watts figure you got from Nvidia is accurate during actual use. Or laughable.

Nor do I know how much a "65w ryzen" processor can draw under certain conditions.

Could well be 400 watts is the most it could possibly draw, but someone will always tell you about "headroom" and "in case you ever upgrade" and "err on the side of caution" and "it's aging" and so you end up with an 850 watt PSU.
