Corsair CX850M, an 850 watt 80 Plus Bronze certified semi-modular ATX power supply, model 75-011012, with a quiet thermally controlled 120 mm fan. The 24-pin ATX harness is attached, and the CPU 4+4, PCIe 6+2, SATA, and peripheral cables are modular.
I am the original owner. It powered a single personal build without a hiccup and was tested working on removal. No known issues.
850 watts is comfortable headroom for a GPU in the RTX 3080 Ti class. This listing includes the power supply and the modular cable set shown in the photos.
