This post is more to hardware, but if you have wound up here, I hope it is useful.
I have long recommended people buy good PSUs when building a new PC. If you use it for work, 8h a day or more, it is a requirement.
Failure to do so may cause the PSU to only last a couple of years and be more expensive in the long run due to short warranties for most. Those that don't have a MOV as spike protection, may not protect your hardware from current fluctuations as a good PSU will!
