Used EVGA 750W Power supply. I used this in my system for a couple of months before upgrading. Never had an issue with it, works great!
Will come with original box and manual. I purchased this in November 2023 from EVGA on Amazon so it is still under warranty, and I can send you the order invoice for it. EVGA has a 2 year warranty on this power supply and you get another 2 years if you register it.
