@Rand My PSU is a 650W. The 7800XT wants a 700W.
Phanteks AMP 650 W 80+ Gold Certified Fully Modular ATX Power SupplyIf it's a quality name brand unit it's not going to be an issue. What PSU do you have?
Asuming it's a modern PSU with a most of the output on the 12V rail, you'll be fine especially since you're using it in a mainstream AMD platform and your CPU will only draw like 6-7A at max load and the GPU will draw an estimated 25A, the rest of the system shouldn't use that much, you should have well over 40A available on a good quality 650W PSU.@Rand My PSU is a 650W.

That's a great, Seasonic-built unit. It will be fine for a 7800XT.Phanteks AMP 650 W 80+ Gold Certified Fully Modular ATX Power Supply
Holy cow. Why do they over estimate the PSU wattage?That's a great, Seasonic-built unit. It will be fine for a 7800XT.
Edit: as per my UPS, my whole system power, including 4K monitor, lamps on my desk, and PC itself, with an i5-11600K and RX 6950 XT which is a hungrier GPU than a 7800 XT, uses 620W - and that's with a CPU stress test and FurMark torturing the GPU, so pretty much worse case scenario.
Do you mind linking the information about the 12V rail please?I found the specs, it can handle upto 54A on the 12V rail that'll power a 6800XT and a 65W CPU no problem with a good 20A to spare.

Newegg list it at 12V@54A, so do a few other places if you Google it, you could also verify it by checking the label on the side of your unit.Do you mind linking the information about the 12V rail please?
Also these days even high end mainstream CPUs from a certain blue company can exceed over 250W while boosting.They can't account for all variables. There are less and less junk PSUs on the market now - most are at least halfway decent and can output their rated wattage - but they don't know that for sure. Plus, they have no idea what the rest of your components are. You could have a dozen hard drives in there! THey don't know - so a higher than neccessary recommended PSU is an easy way for the manufacturer to decrease the likelihood you'll have power issues.
So much for e-cores e for efficiency. Riiiiight.Also these days even high end mainstream CPUs from a certain blue company can exceed over 250W while boosting.
I see it. Thank you!Newegg list it at 12V@54A, so do a few other places if you Google it, you could also verify it by checking the label on the side of your unit.

So about 400w at the power supply? Net is different than at the UPS.. the UPS number has conversion losses too over 10% usuallyThat's a great, Seasonic-built unit. It will be fine for a 7800XT.

Of course the power supply has to cover the power spikes to so you want extra capacity. I also think a seasonic based 650w is ok.
