This is new and un used and has never been turned on. This version of the HX1000 is very similar to the HX1000i but lacks corsairs iCUE software compatibility. For settings this model is set it and forget it in the bios like usual, no fancy desktop icon for your psu. I bought this for a PC build however I ended up going with a mini-itx build in the end which required a different power supply unit/PSU. It was by this point too late to return for a change of mind. I held onto this incase I ever swapped to an atx build. It’s just been sitting in storage. I originally choose this item because of the reputation it had in the community for being one of the best PSUs. High performance, premium components, Ultra low noise.
