And can I buy now a more powerfull PSU for my upgraded system, and how much more w's it chould be? DelroyMonjo November 21, 2011 11:20:07 AM If you think you will upgrade to another 6950 soon, consider a 650W PSU. Power supplies are long term, Mobo's and video are short term in the computer world. 13thmonkey a b ) Power supply November 21, 2011 11:23:08 AM for twin 6950's? i'd say 700 from a good manufacturer. Droozel, how many amps does the 6950 say its needs? http://forum-en.msi.com/faq/article/power-requirements-... I'd suggest you want 50Amps to allow you to go to crossfire. which means a minimum of 600W, if it can all of those 600W on the 12V lines. Hence I'd be thinking in reality 700W. droozel November 21, 2011 11:34:44 AM OK guys, thats more info than i can imagine, so what can you recommend to me? A good quality 650-700W but not very expensive, because im on a tight budget... FinneousPJ a b ) Power supply November 21, 2011 11:35:13 AM I'd say min 650W for the crossfire setup. 700W would be safer. droozel November 21, 2011 12:12:42 PM Yes ok, but im a little bit out of the way regarding PSU's brands, can someone recommend a good price per value brand or model that does not doing noices of a train passing by Can't find your answer ?
