How Are PSU rated, At the wall or componant draw?

post #1 of 5
Thread Starter 
Hello,
Iv got a Antec Neo Eco 620W and just wondering how they come to max draw ratings.
Iv got it folding at the moment on GPUs and CPU and my rig is pulling 650-680W from the wall.

If they are max rated by the components I take it im with in the safe zone since its rated as a 80+ bronze so it would only be drawing 545W and from reviews of the PSU they could take it to 780W before it shut down (dont know if that was from wall or components tho)

I know I should really get a bigger/better PSU or lower my overclock but i only plan on folding for the chimpchallenge and when gaming it only pulls 400ish from the wall so dont see the need to upgrade it.

Its only shut down on me once and that was from the cable tie for the fan over the VRM slowing the fan down on the PSU but iv trimmed it now so its no where near it.

Your PSU is fine man, they rate them by what they put out in DC voltage, not what they pull from the wall (AC voltage). Big difference there. Your unit is capable of at least 620w DC.

As has been stated, they're rated for output (most things are, since that's the figure that's more important).

If you're folding 24/7, that's still a pretty high sustained load though: around 540W on a 620W PSU, even if it's a decent model. It's a Seasonic inside, but a more budget-oriented design, and with some second-tier Chinese capacitors in there. It should be fine, but it's not ideal.
