Masterchief79 Posted May 6, 2020 Share Posted May 6, 2020 (edited) Hey guys, this card worked for about 3 years as a daily driver (wasn't OCed) when it started to crash the PC. It would just shut off instantly, like when it's a PSU issue. The PSU was fine though. I replaced the card and the problem went away. I finally got around to repairing the card and traced the problem down to one of the Mosfets. The card powered up when I would leave the 8-pin out - the 8-pin powers the lower 4 GPU Mosfets - and sure enough, one of them was fried (no resistance between two of the pads). The card powers up fine with the 8-pin in now, although the lower 4 Mosfets are still out. First question: What kind of manufacturer is this and where can I get a replacement Mosfet? A datasheet would also be helpful I guess. Second question: Should it already show a picture on the screen now with 4 deactivated phases? Voltages and everything look good. Or does this indicate there might be something else bad (like the GPU itself?) Edited May 6, 2020 by Masterchief79 Quote Link to comment Share on other sites More sharing options...
