PSU Under Power?

post #1 of 9
Thread Starter 
Planing on folding 24/7 for CC. Catch is I plan on using my 965 (4.2 1.4v ATM...) with my 1.3V 6970 (990/1500) AND a pair of 9800GTs. Can the system do it on my HX-650?

It's unlikely as this is a system that can pull 500W at stock speed. You can try to power the rig @stock speed and then start OCing and OVing one at a time to see how the PSU holds. It would help if you'd have a way to measure power consumption, this way you'd be able to evaluate how much the internals are consuming (plug power*~0.8) and see if you fit within the rated wattage of the PSU.

My guess is that it could hold all of this and one of these OCs, not both, or not both pushed as far as that.

With all three GPUs and that CPU going full blast you are gonna be pushing it. It defintiely won't be running efficently (costing you more on electric bill).

If you are gonna be running all that 24/7 you should step up to a 1000W unit, so that under full load, you are around 50% of the power supply's peak where is it most efficent

Yes, it should be enough. It's a decent PSU.

I checked my system and with an i7 970 @ 4.2 Ghz 1.31v,a GTX 470 @ 750/1500/1700, and a 9800GT @ 675/1687/1000 i pull 580W from the wall I'm using an NZXT HALE 90 650W

edit: That is with all 3 components folding

Are you referring to my 1000W suggestion? Did you not read the post? Of course it's overkill, but the point is to get maximum efficency for a 24/7 load machine... That happens around ~50% peak

You did notice that it's his sig rig PLUS 2 more 9800GTs right?

Just giving suggestion to save $$ and go green!

The 40-60% load recommendation does hold when it's a 24/7 load machine.

Thanks for the imput so far.

This setup only has to run for the next 10 days of CC. After that its back to just the one 6970
