Andrix85 Posted April 26, 2012 Share Posted April 26, 2012 Hy boys !!! Today i have received one ATI 5970 to overclock with my system. I use a 2600K @ 5.7GHZ @ 1.65V under Phase Change with a MSI Z77 GD65 and the 5970 with stock cooler. When I start the system the mboard debug show me d3 error that mean VGA POWER. My psu is a CORSAIR TX750V2; Must I need more watts? It's the Corsair 750W insufficient for the system's overclock ? Can I use two psu ad alternative ? Thanks and sorry for my bad English..

nedernakker Posted April 26, 2012 Share Posted April 26, 2012 you can use 2 psu's, 750W could be short. test it to find out.. Quote Link to comment Share on other sites More sharing options...
Andrix85 Posted April 26, 2012 Author Share Posted April 26, 2012 you can use 2 psu's, 750W could be short. test it to find out.. Why can I use two PSU ? I can start the second without mboard ? I can take a 500W PSU to use with only vga card... Quote Link to comment Share on other sites More sharing options...

Andrix85 Posted May 7, 2012 Author Share Posted May 7, 2012 short circuit the green wire with a black one on the 24pin connector Thanks... But I have seen a strange thing about the mboard. I have upgrade the last bios v 10.5 and the vga card boot with the only TX750V2 PSU. Why? with the other bios V 10.2 don't boot. It's very strange this MSI mboard.
