troy5061 Posted December 11, 2008 Posted December 11, 2008 (edited) I know the Corsair 750w is a good unit, a few buddies have them and they get raving reviews but im worried about it being enough to run my 2 2900XTs. Ati recommends at least a 750w to run them both and im getting conflicting reports from various reviews on how much power they actually use. Ive seen one review that burned out a couple good brand 750w units and one review that said the system with overclocked cards was milking 575w which would lead me to belive the Corsair would be enough. Any thoughts on whether Ill be ok with the Corsair or not??? I can get it for $99 at ZZF $84 after the rebate which is half the price of the Antec 850w im looking at as an alternative. The antec 1000w was $159.99 shipped last night but I didnt get it in time and they bumped the price back up to $229.99.

Yoosty Posted December 11, 2008 Posted December 11, 2008 You should be ok, but if you still want to get a bigger PSU. Buy.com has a deal on the Corsair CMPSU-1000HX ATX12V &EPS12V Power Supply - CMPSU-1000HX for $174.99 after rebate, but it ends in the next day or two. http://www.buy.com/prod/corsair-1000-watt-.../207510101.html Share this post Link to post Share on other sites More sharing options...

paulktreg Posted December 11, 2008 Posted December 11, 2008 Two 2900XT in crossfire is an absolute maximum of 350W. The Corsair TX750W is a great power supply and will be more than enough. Cheers Paul Share this post Link to post Share on other sites More sharing options...
Krieg1337 Posted December 11, 2008 Posted December 11, 2008 I would get the PC Power and Cooling 750, ran two PRO's which were somewhat overclocked. It's pretty cheap too Share this post Link to post Share on other sites More sharing options...
Pilliy Posted December 12, 2008 Posted December 12, 2008 Most of my friends and I are running a HX-620W. It handles 2x 4870s with a quad core processor. So the 750W would easily handle what you want to throw in But as Yootsy said, if you don't feel like it will be enough go get the HX-1000 and watch your equipment cower before it!

Hyper Threaded Posted December 12, 2008 Posted December 12, 2008 Corsair PSUs are quite strong, no need for 1kw. In fact, a 1kw PSU is complete overkill in any modern system. Share this post Link to post Share on other sites More sharing options...
tanka12345 Posted December 12, 2008 Posted December 12, 2008 I think 750W is enough, but it's better to be safe than sorry. Share this post Link to post Share on other sites More sharing options...
devit Posted December 12, 2008 Posted December 12, 2008 1k is too much...but if u plan to change something in the near future..who knows maybe it won`t be.like other members have told you...750w for the moment is more tha enough.

troy5061 Posted December 12, 2008 Posted December 12, 2008 Thanks for all the help guys!!! The Antec Truepower Quattro 1000w is $179.99 shipped on Newegg vs the Corsair at $119.99 shipped so I guess its going to comedown to how much I value $60.00.

damian Posted December 12, 2008 Posted December 12, 2008 Save those $60 for something else, go with the 750W. Share this post Link to post Share on other sites More sharing options...
Krieg1337 Posted December 12, 2008 Posted December 12, 2008 The PC Power and Cooling 750 is probably the best price/performance PSU, go with that. Except if you want to run 3 GTX 280's. Share this post Link to post Share on other sites More sharing options...
