Solved System Rebuild Tags: Prebuilt Intel Systems Product Last response: April 14, 2012 9:27 PM in Systems Share skribbz14 April 14, 2012 7:57:30 PM I am about to rebuild my system and have a new processor, mobo and graphics card picked out. I don't really know how to check if my current power supply I am using will be compatible. These are my new parts: ASRock Z68 Extreme3 Gen3 LGA 1155 Intel Z68 HDMI SATA 6Gb/s USB 3.0 ATX Intel Motherboard http://www.newegg.com/Product/Product.aspx?Item=N82E168... XFX HD-679X-ZRFC Radeon HD 6790 1GB 256-bit GDDR5 PCI Express 2.1 x16 HDCP Ready CrossFireX Support Video Card http://www.newegg.com/Product/Product.aspx?Item=N82E168... Intel Core i5-2500K Sandy Bridge 3.3GHz (3.7GHz Turbo Boost) LGA 1155 95W Quad-Core Desktop Processor Intel HD Graphics 3000 BX80623I52500K http://www.newegg.com/Product/Product.aspx?Item=N82E168... and this is my old power supply I am hoping to continue using: CORSAIR Builder Series CX430 CMPSU-430CX 430W ATX12V Active PFC Power Supply http://www.newegg.com/Product/Product.aspx?Item=N82E168... Thanks again in advanced for any help! More about : system rebuild Best solution jsc a b å Intel April 14, 2012 8:09:10 PM You will need a more powerful PSU. A 6970 needs about 17 amps, peaking to 21 amps under load. Your CPU will need about 10 amps. And that doesn't include the rest of your system. A CX430, while a pretty good power supply, only has a 28 amp 12 volt rail. I would recommend something like an XFX 550 watt PSU: http://www.newegg.com/Product/Product.aspx?Item=N82E168... a little pricey for a 550, but a great power supply and built by Seasonic. Or one of these: Corsair CX600 http://www.newegg.com/Product/Product.aspx?Item=N82E168... But my first choice would be the XFX.
