Power Supply rec for 24/7 load on OC'd i7 950 - Page 2

Drop the oc down to 3.8 or 3.6.. it'll use a few hundred watts less power.
Wow! Never knew that. Go with a 600+ watt then.

Yup. Most people don't realize how bad energy efficiency gets once you start hitting certain clock speeds/voltages. I'm willing to bet that 4.2ghz would want another 75-100 watts..

Not only is it hard on your PSU, it's hard on your energy bill and it's just wasteful imo. find a good balance between consumption/performance.

OK thank you guys. +rep to all :-)

like i said, im a n0ob to PSU's. Didnt know if one allowed for more CPU power than others or not. I thought that I had read that the i7 consumed +300w alone @ my clock speeds. Really though, the power bill is fine. But I will look into lowering the clock maybe. As I fold (bigadv) I have to have certain TPF so we will see how this impacts it. I need to just get a 2600K lol.

TX650 v2, you won't need anything more than that and it's a solid PSU.

I should have just gotten the 2600k. Less power consumption. And for 210 shipped? i mean srsly!?!?!

Does that power draw problem happen to the 2600k? Maybe I should stop running at 4.5Ghz.

EDIT: I think it's still over $300.

Yup. The 2600k is really an insane chip in terms of energy efficiency/performance.

first gen i5s/i7s are pretty bad with power, way worse than I would have thought anways

Nope. Decently efficient chips imo

My 920 at 4.0 folding 24/7 uses 255-260w according to my kill-a-watt. I did fold during the chimp challenge with a GTS450 and was pulling 365w with it then. A 600w will do just fine. I'm using a Cooler Master silent pro 600, great psu and is damn quiet.

Actually, NZXT's recent Hale90 PSUs are excellent. However, I doubt the OP got one of those if it was free.

Wasnt quite free but yea... its a NZXT Precise Power 650w. I got that along with an NZXT case and mobo, cpu, ram, etc etc, 8800gt for 50. Well I still have to pay him (my friend) that was ~1yr ago.

Which one?

750w
http://www.newegg.com/Product/Produc...seasonic%20750

650w
http://www.newegg.com/Product/Produc...82E16817151088

I can do either but the 650 is more in my price range lol... bought a 25 dollar difference between the 2 after shipping
