Cooler master psu
RS-550-ACAA-a1 and RS-550-ACLY got difference? which one better RS-550-ACLY seem more expensive
a1 is thew real power pro, with mesh on the cable (tidyer), the ACLY is basicly the PSU without coverin, but does come with a PSU monitor that can sit on the case or in the case in a DVD slot.
i must admit that these 2 PSU's are great, as i have the 520 mudular of the real power pro
and i am very pleased with it.
