Solved Crossfire 5850's with 650W PSU? Tags: Power Supplies Crossfire HD Components Product Last response: February 26, 2010 12:57 PM in Components Share GlenK February 25, 2010 8:01:48 PM I'm looking into building a PC with a X4 955, 2 HD's, and for now a single 5850, but would like to add another in the future. This seems like a pretty good deal, just wanted to verify that I could run two 5850's in the future with this PSU. http://www.newegg.com/Product/ComboDealDetails.aspx?ItemList=Combo.326297 More about : crossfire 5850 650w psu Best solution JohnnyLucky a c 248 ) Power supply February 25, 2010 11:23:42 PM First, the system requirements!

It should not have any problems powering your system with two 5850's.

All I could find was this: http://www.jonnyguru.com/modules.php?name=NDReviews&op=... The Black Editions fared better: http://www.jonnyguru.com/modules.php?name=NDReviews&op=... but considering the price on that one on newegg, I don't think they are in the same league. m 0 l JohnnyLucky a c 248 ) Power supply February 26, 2010 12:01:38 AM Jack - never mind! Too many models! Confuses the heck out of me. m 0 l GlenK February 26, 2010 12:57:59 PM I believe the one on newegg is the same as the one you linked Jack(the first link) and the same one Johnny linked as well. Even though the model name doesn't say XXX on newegg, the model number listed: P1-650X-CAG9 is the same model number for the 650 xxx listed on XFX's website http://www.xfxforce.com/en-us/products/psu/xxx/P1-650X-CAG9.aspx Also, according to XFX's website, they only make one model of 650w power supply, so it's gotta be the same one as far as I can tell. m 0 l Can't find your answer ?
