OCZ ModXStream 500W - enough for 3x 450GTS

post #1 of 10
Thread Starter 
I still haven't gotten my XFX 750 RMA'd, so I'm running two 450's in SLI right now + the 2500K. Possible to toss in a 3rd 450 for folding, or would I finally be overbudget?

Shows total system power consumption at 208W - I think you should be able to pull 3 with a little room left

No chance... your PSU will run very hot aswell due to running at high output.. I would recommend a 750w psu which should have a little headroom..

Two 450s on a 500w? Easily
Three 450s on a 600w? Also easy
Three 450s on a 500w? Could work, I have my doubts

The ModXStream has like 430w on the 12v rails
Nvidia has them labled as 100w cards on their site, dunno if they will draw that much though. Trying to find some benchmarks at the moment..

EDIT: Yeah I'm going to say no. Over 400w from the wall with 2 way SLI over at guru3d, cutting it too close for folding imo.

Will work but might be cutting close. Try it out? See if it restarts or something.

It will be closer than I like. It might work, but I won't recommend it, certainly not long-term.

I knew it would be uber close, I probably won't risk it then...

When folding on all three, you're probably looking at ~25A just for the cards.

Well if that's the case, then that would leave him approximately 10A leeway. I'd imagine that would be enough for the rest.

But as phaedrus said, it's probably a little close for comfort.
