    This is the 2nd unit In purchased to get my office PC back up and running again. Computer was randomly restarting at will . Got to the point that it would start up to the bios logo and recycle . Purchased this one and all was well . I was issued an exchange for the the original PS and kept it for backup. Not even 2 moths and this is doing the same . Just replaced with the warranty exchange and all is fine again . This is apparently an issue with this PS as described on forums .

    Chick who delivered it to me didn’t care about the package and just slid the package under the fence causing the package to rip and the box to rip too so bad delivery. But it’s okay and working.

    This is a replacement for one that went out just under a year of having it. So far it’s working well. Time will tell, hoping it was just a fluke.

    Not my first time buying this PSU but it failed after 2 days of very minimal use. It failed in my last PC but it maybe an issue with just this model, I recommend getting the new gen version of this or go with at 750
