LithStud Posted December 16, 2013 Share Posted December 16, 2013 Hi, i have encountered strange problem with TX650 power supply and powercolor 5970 graphics card. The problem: - After inserting this card and connecting everything as it should be and powering up the PC screen is black, nothing happens, no bios POST, nothing. All the leds and fans both on MB and 5970 are lit (5970 goes into berserk with 100% fan speed). 5970 also indicates that there is not enough power (two red leds on the back of the card). Whats strange about this? I tested same graphics card at work with PSU of just 530W (no idea whats the manufacturer) and it works fine (loads right to the windows). My first guess was maybe MB too old, so i basically upgraded all of the old components (Gygabite G1.Sniper B5, Corsairs 2x4GB DDR3, intel i5 4570S 2.9GHz) and it still is the same problem. The old GeForce GTX260 works fine. I know that 5970 needs 20A on 6pin and 15A on 8pin rails. Link to comment Share on other sites More sharing options...
