Need help with a DPS G RGB 750W. I am building a showcase system, using a P5, 3900x, and an RX 5700 XT. I finished the build, and rechecked all the cabling. I powered up the PSU, first, no RGB from the fan, then one of the wires on the 8 pin connector to the motherboard literally melted from the PSU to the mainboard. This PSU came straight out of the box and into this build. It had never been used before now. If there is damage beyond the failed PSU, do I contact Thermaltake? All the components are brand new.
