ugh. I blew up another PSU and a riser. Thankfully the GPU in the riser still works. Phew. Now on to the lesson. Again.
PLUG YOUR MOTHERBOARD, CPU, AND ALL POWERED RISERS INTO ONE PSU!!! I had my motherboard and CPU powered off of one PSU, and I needed to add another GPU. I got too lazy to hunt down the molex string for the "main" PSU (it was stuffed in the back of the chassis somewhere), so I hooked this new GPU (both riser power and GPU power) into the slave PSU. Whelp... looks like there was backfeed. Blew the riser into hell, and shit the PSU in the process. I hear some of you giving advice to split the riser power among multiple PSUs... and I know it depends on riser model and motherboard model and PSU model and even GPU model sometimes (and it might work for some of you), but like
goddamnit
please dont learn the lesson the hard way
please
