hidethecookies Posted May 12, 2018 Posted May 12, 2018 (edited) I just bought a GTX 780 classified that was supposedly broken on ebay. I paid $60 and I planned on using it for a homemade epower. Seller stated PLL light was out which means that PLL vrm isn't functioning. PLL is a rather low volt and current vrm most cards are 1-1.25v at less than 5a. I figured I would try to put a little ebay 3a dc-dc buck converter I had for other zombie projects to power the PLL. If that failed then I would cut it in half and have an epower. When I got the card I noticed 3 missing smd caps and one resistor. I figured the caps didn't really matter but checked on Techpowerup hi-res picture for resistor size. It happened to be 0 ohm. I just used a small piece of copper wire and soldered it in. Then tested it out and it fired right up. I ran a few stress tests and oced a little. I can get 1350mhz @ 1.2v So is it worth keeping whole or just cut it up for epower?? Edited May 12, 2018 by hidethecookies Add picture Quote
TAGG Posted May 12, 2018 Posted May 12, 2018 (edited) Keep whole and OC to the max I had the same thing happen to me recently, bought a Gigabyte 1080 Xtreme Gaming for epowering, it had a short on some little vrm (that i still dont know what it was good for) after i removed one of the FETs it worked fine and is my daily driver now (with a 10 phase VRM instead of a 12 because 2 of the main phases are also dead)... I guess there could be worse surprises than finding out the broken card you bought works Edited May 12, 2018 by TAGG Quote
