Been using this PSU for 1 year now, bought this used from Amazon, and has never given me any trouble, comes with all the cables, the manual, and PSU tester along with the screws. Upgraded to a 850W PSU which is why I’m selling this now. I will be using the box that came with my 850W PSU because I do not have the original 750W PSU box anymore, everything will arrive packaged for safe delivery. If you have any questions please let me know by messaging me, thanks for your interest!
