This is a PSU in used condition. It has the latest PCIE 5.0 power connectors, not just one, but TWO of them. You can run dual 4090 GPUs powered directly from the PSU WITHOUT the need for the controversial adapters that come with those graphics cards. That much power comes with heat.
PLEASE NOTE: this PSU has an aggressive fan curve for a hybrid mode PSU, which is set BY DESIGN FROM FACRORY. This means that on high loads, the fan with spin with very high RPM. On low loads it will remain silent. A couple of other peculiarities: 1 when you turn the hybrid mode to off position, the fan will be relatively loud as it goes to a factory-set constant high RPM mode. 2 when you turn your system off, like many other high-end PSUs, the fan will stay active to high RPM for a good few seconds, and then it will turn off.
It has something to do with the design and capacitor discharging. It comes in original box with all cables, in decent used condition. It has been tested and stress-tested.
