So I bought a thermal camera a while back and decided to check out my server with it and boy am I glad I did, one of the 12VHPWR connectors is only supplying power on two conductors. Each of the two wires is supplying 18 amps at my power cap of 450w, I've been running it like this for a while with no visible connector damage yet but that doesn't mean it's ok. Here's a few photos of the cables.
Been running this rig for about a year now, built it before the price surge on ram and GPUs. 7970x, TRX50, 256gb DDR5 6000, 4x RTX 5090 with bykski water blocks, nEXT CPU block, PMP 500, external 12x18 radiator to put the heat outdoors. 1600w superflower PSU, 2x 2000w crps with c-payne dual crps breakout board for total of 5600w. I plan on building a base to set the PC case one that will hold more GPUs on a PCIe switch backplane in the future. I'm still getting 5090s for 2k each so I can do things that otherwise wouldn't make sense. This thing currently runs 70b models so fast it kicks commercial ai subscriptions ass.
7970x, 256g ram, TRX50 platform and 4 RTX 5090 with bykski water blocks.
