BittonShai Posted June 25, 2008 Posted June 25, 2008 I'm in a little bit of a problem here guys. Does anyone have any recommandation about how big ? what manufacter ? Would appriciate any help aviable on this subject. I thought of either the Antec TruePower 850 or the Zalman ZM850-HP would appriciate if anyone that got either would let me know of his personal expirience with them. Thanks in advance.

Comp Dude2 Posted June 25, 2008 Posted June 25, 2008 500-600W or above would be fine...a PC P&C 610 is a favourite. Share this post Link to post Share on other sites More sharing options...
Ste Posted June 25, 2008 Posted June 25, 2008 ^^ Thats a good choice. But atm, the 750TX is one of the best bang for you buck power supplies out there.. either way, there are many many many choices and I really cannot reccomend one so many, But I would stay within the brands of: PC Power and Cooling Corsair Seasonic Silverstone Share this post Link to post Share on other sites More sharing options...

damian Posted June 27, 2008 Posted June 27, 2008 (edited) the PC power and cooling 610W only has two PCI-E connectors, in order to run two 4870's you need 4 PCI-E connectors. Here are some good ones to choose from: SeaSonic M12 700W - http://www.newegg.com/Product/Product.aspx...N82E16817151031 Corsair TX750W - http://www.newegg.com/Product/Product.aspx...N82E16817139006 PC: Power and Cooling 750W Crossfire Edition - http://www.newegg.com/Product/Product.aspx...N82E16817341011 Silverstone ST85F 850W - http://www.newegg.com/Product/Product.aspx...N82E16817256011 Edited June 27, 2008 by damian Share this post Link to post Share on other sites More sharing options...
CanadaGUY Posted June 27, 2008 Posted June 27, 2008 Ya the Corsair 750W is a great deal right now Share this post Link to post Share on other sites More sharing options...
OrangeJuice Posted June 29, 2008 Posted June 29, 2008 (edited) http://www.newegg.com/Product/Product.aspx...N82E16817814001 I recommend 2 of these. Edited June 29, 2008 by OrangeJuice Share this post Link to post Share on other sites More sharing options...
Praz Posted June 29, 2008 Posted June 29, 2008 750W may work for you but anything below that size and you're doing nothing but wasting your money. ATI doesn't even list an approved PSU below 800W for dual 4870 cards. Makes no sense for most users to purchase a 1000W or higher power supply but makes even less sense to try to get by at a minimum.

Praz Posted June 29, 2008 Posted June 29, 2008 Benchmarks show that a 4870 in crossfire is about 420W total. Then maybe ATI should revise their specifications. On second thought they probably wouldn't as they use the proper equipment capable of showing instantaneous maximum loading. Unlike review sites using $12.00 watt meters.

cirro Posted June 29, 2008 Posted June 29, 2008 """http://www.newegg.com/Product/Product.aspx...N82E16817814001 I recommend 2 of these. """ what would need 2600w power supply? that is MASSIVE overkill plus that would be around $800 for PSU's i can build a whole PC for that. your electric company would love that though.
