csaari Posted March 17, 2009 Share Posted March 17, 2009 Hi everyone! New member here. I decided to upgrade the video card in my home-built PC. My old power supply didn't have enough power to run the new card, so I picked up a TX750. I hooked it up, and when I plugged in the power cord, and turned the switch on the power supply on, my case fans started spinning very slowly. When I hit the power button on the PC, nothing happened. I have a basic power supply tester, which just has LEDs for each of the power rails. When I plug the 24 pin motherboard connector into the tester, and turn on the power supply, all the fans run at their normal speed, and all the LEDs light up except for the one for -5v. (I have not tried the paper clip test....) Does it sound like I have a bad power supply? I bought it at a local retailer, so I can take it back and exchange it for another one. I don't currently have another power supply I can try, nor can I easily try the TX750 in another PC. I can put the old video card and power supply back in, just to make sure everything still works, but of course, I'd prefer not to. Well, thanks in advance for any suggestions!
