Hunting a replacement power supply for my old Corsair 850w that's on the way out and this is probably the most competitive priced 10 year warranty 750w PSU I've found lately.
From a quick look at reviews seems not quite as good as a Corsair RM750x when it comes to noise and efficiency, but long warranty and a reasonable build quality from Cooler Master so you should be pretty right!
The thing that irritates me the most is squeaky noise some PSU made, once i hear those noise i know there's something wrong with the PSU, i brought two seasonic x series before they all have the same issue, 4 Corsair units over the past 10 years, absolutely dead silence, i think they are worth the price.
