Closed Upgrading to Sapphire hd radeon 6770 Tags: Radeon Sapphire HD Graphics Product Last response: February 12, 2012 6:30 AM in Graphics & Displays Share theddd1 February 12, 2012 2:51:22 AM Hi! Im currently trying to upgrade my computer from a sapphire hd radeon 5570 to the 6770. The 6770: http://www.newegg.com/Product/Product.aspx?Item=N82E168... However the PSU in my system is pretty bad, its a Logisys 480 Watt PSU. However I was tricked into buying it when I eventually figured out it only had 16 amps on its 12 V rail. So my question is, in order to have the Sapphire hd radeon 6770 in my system, what PSU would I need to run it smoothly. Currently Newegg is having a sale on all CORSAIR power supplies so I was looking at this one. http://www.newegg.com/Product/Product.aspx?Item=N82E168... Would 430 Watts on a 28 Amp 12 V rail be enough to safely power the 6770? Current Computer specs: Sapphire HD radeon 5570 OC 4GB 1333 DDR3 RAM AMD Athlon II X4 3.0 Ghz. 480 Watt 16 Amp@12V rail Logisys PSU.
