New!! How to Diagnose GPU Faults with a BENCH PSU
0LER #155: In this video I look at a new technique using a bench power supply to test and diagnose graphics cards. I use a multimeter to confirm the problem, but the bench PSU is telling me what is wrong with the GPU.
I've not seen this technique used elsewhere, hopefully it is a new approach for many of you learning GPU repair.
In particular I found that it gives you clear visible evidence that the GPU runs (or tries to run) after the Power rails come up.
