I started expirimenting with local AI, but i clearly dont know what i am doing as i blew up my PSU two times now! :S
So i thought this would be a good time to ask for advice... Im expirimenting with this setup;
- I have a X670 GAMING X AX V2 motherboard (https://encrypted-tbn0.gstatic.com/images?q=tbn:ANd9GcRtBTCDzQlZdCitzI-A1cu_7cz1Hjsn_Auvd2YQOWbWHRpvk-dlOuuArCjI&s=10), paired with a 7950X cpu and a (now dead for the second time) 1200W PSU (FSP Hydro PTM PRO ATX3.0 (PCIe5.0) 1200W): https://tweakers.net/pricewatch/1877116/fsp-hydro-ptm-pro-atx30-pcie50-1200w.html
- In my main PCIE X16 slot i have a 4090
- In the (top) three M2 slots, i connected 3090's (forcing PCIE 3) and an oculink adapter (KALEA-INFORMATIQUE M2 to Oculink SFF-8612 - https://www.kalea-informatique.com/m2-nvme-m-key-to-oculink-sff-8612-pcie-4-0-port-adapter-with-20cm-shielded-cable.htm). I expirimented with using the X4 pcie slot, but didnt get that to work, the top 3 m2 slot did work with the 3090's. Each 3090 is hosted on a MINIS FORUM DEG1 and has a dedicated psu (Sharkoon Rebel P10, ATX 3.1, Cybenetics Silver, 850 Watt).
Now when i run some llama.cpp benchmarks, i heard the main PSU make weird noises, i looked it up and it seems likely coil whine. The first time my PSU died I thought it was because it was already a few years old, so i ordered a new one. The new one worked for a couple of sessions, but the PSU gave up again!
Does anyone recognize this problem or maybe sees a problem in the combination of these components before i order a new (heavier?) PSU again?
Thanks in advance!
