Will 750w be enough?

Thinking of a 750w PSU

See sig for spec, but will be switching to I7 in a few months and adding in second GTX280 bought in the OCUK sale.... Will that do the job.... Or should I go higher?

95thrifles · 29 Jan 2009 at 09:54

Yeah 750 should be OK

icey_haj · 29 Jan 2009 at 09:56

Yup 750 is enough

littlepuppy · 29 Jan 2009 at 10:00

Even with pysx?

icey_haj · 29 Jan 2009 at 10:03

Liquidfox · 29 Jan 2009 at 10:03

The 9600 isn't a high powered card, and can't draw more than it normally would just because it's processing PhysX... so 750W will be fine

littlepuppy · 29 Jan 2009 at 10:05

OK final question then

850w Coolermaster

or 750 W dark power as I can get either for same price...

icey_haj · 29 Jan 2009 at 10:10

Well both are good. BeQuiet tends to be quite expensive and is obviously a good PSU, so if you can get it at the same price then it's great. 750w is also more than enough, I would try out the Dark Power.

can get the 750 here as a bgrade item... 109.99 or the coolermaster for 104.99, cant decide!

StephenLawUK · 29 Jan 2009 at 10:25

i recently got the coolmaster comes with all the modular cables you could ever want i have so many spare lol. Its also very quiet.

icey_haj · 29 Jan 2009 at 10:26

If the coolermaster is new, then I would go for that.

I wouldn't buy a b grade item personally..... *runs and hides*

Have you checked out this Zalman, also very good

edit: I also own a coolermaster, very happy with it

littlepuppy · 29 Jan 2009 at 10:37

yes thats another I looked at, dont know why just not sure about zalman for a PSU, plus coolermaster has 5 year warranty....

May well be totally irrational..

Go for the coolermaster then, you won't be dissapointed

Cheers guys, decision made, ill get one :-)

PS opened my case and found my seasonic at the mo is only a 500W version ! lol thought I had bought 600!

icey_haj · 29 Jan 2009 at 11:41

^ lol

Kennysevenfold · 29 Jan 2009 at 12:24

yeah of course it is, wouldnt draw more than 500-600 i would think mate

littlepuppy · 29 Jan 2009 at 14:22

Right well just made a trip to a competitor - normally always shop at ocuk but thought id get this lunch time and then fit tonight, but competitor as is the case v often just says "normally in stock" against items - they hadnt got the coolermaster - only the 1200 / 1250 watt version and i didnt want that, so I have ordered from OCUK the

**B Grade** Be Quiet! Dark Power Pro 750W ATX2.2 Modular SLi C

Thanks for all the advice lads - im just a bit worried it wont be enough but the internet posts around the place seem to confirm the general opinion here that it should be.... I mean min draws around 350w under load at the moment..... (with the voltage reader I have)

Ill let you know what its like when it (hopefully) arrives tommorow!

Like it should, that 280-300W is peak draw for those parts.
One GTX280 more will add 180W at most to that.

littlepuppy · 29 Jan 2009 at 16:38

Cool, and if its drawing 500W say, at 80% efficient that means the PSU is only dishing out 400 so should be well within the compass :-)

Its been despatched, so Ill run a test when it arrives, see how much it uses with all 3 gcards and the CPU folding :-)

littlepuppy · 30 Jan 2009 at 13:22

K its arrived, ill look to test some power readings, considering its "b" grade it was all boxed up very nicely and seemed pretty much new. Fingers crossed it works!
