Seeing as how PSU prices are quite high, I figure this is a pretty decent deal when even the crummier 650-750w units are now $140-150 while a Corsair RM 850w unit is $199. This is an older PSU platform but it's essentially a Seasonic Platinum XP3 underneath so it's capable of running completely fanless with high efficiency up to 500w for 25 minutes or so. This used to run for $400 or so but has been dropping steadily over the past while. Also comes with a 7-year warranty.
