Is my temporary PSU ok?

Hi folks,

I've had to RMA the PSU in my signature, and there's no way I'm waiting several weeks for it to come back without having a computer

I've got an old Corsair HX520 watt PSU - will it have enough juice?

Planning on taking my overclock off, and I know that my 7970 takes about 200 watts under load. I've got 3 fans, 5 HDDs, and a few LED strips, in addition to my signature.

Thanks

According to the online psu calculators you only need a touch over 400W without the overclock. It's probably just about big enough even with the overclock still applied.

Google 'psu calculator' and run the figures yourself.

It should be fine... unless it's lost a load of capacity over the years but, it been a Corsair unit, you should be fine.

Yeah it's about 4 years old. Ran the numbers on a PSU calculator, getting about 450 watts.

Just wasn't sure quite how close to 520W I could be.

Is it possible to damage other components, or would my PSU just give out if it couldn't keep up?

The PSU calculators suggest the size of PSU you need, the additional capacity margin is already built in.

HA!!

Kind of makes me feel bad about running a 1000w PSU when my calc came out at 350w. hmmm....time to downgrade me thinks :S

Depends if its a decent 1000W PSU or a pile of junk

Most people go mad on PSUs for no reason at all, it'll be fine.
