Can the HX850 do this?

post #1 of 21
Thread Starter 
I'm wondering if my HX850 can manage 2 GTX570 Twin Frozr's and 2 768mb EVGA SC GTX460's and all 4 at 100% 24/7. My cpu is at 4.0 and I have 3 hard drives.

Edit: what about minus 1 460?

highly doubt it.

that would push it to its limit and probably beyond it.

I'd say it'd be very, very close, and probably too much for 24/7 use. You have around 700w worth of just GPUs there, add in the rest, including the 4GHz i7 and you're talking near 1,000w. I know the HX850 can do it, but it would die very quickly under that load if you tried to sustain it for a long time with everything full on, like folding with it.

Folding. >.>

General consensus is no, what about minus 1 460?

With everything at stock it might just scrape by.... but with overclocks I'm gonna have to say no.

Is this for folding? The HX850 is a underrated unit, but OCN does not recommend it. The GPUs themselves draw close to 800 watts. You may be able to run it initially, but under full load, this beast will draw over 1000 watts.

GTX570 is 220w and GXT460 is 160w but they use less in folding most cases but some units may draw more. We know hx850 usually does more than its specs but in this case, it is on edge.

I'd suggest at least the hx1000 for your needs at minimum for 24/7 use. The AX1200 would be your best bet and the best for your electricity bill as well as you'll get better efficiency.
