March 5, 201115 yr CORSAIR Builder Series CMPSU-600CX 600W ATX12V v2.3 Active PFC Power Supply $34.99 after promo EMCYTZT329 and MIR (promo is valid from 12:01am PST on Saturday, 3/5/2011). This isn't a PSU that I normally use just because it doesn't fill a specific need. It is too small for 20+ drive support, but overkill for 15 drive support. The 40A single +12V rail is suited to support around 18 or fewer drives. Most servers don't fall in the 16 - 19 drive range, and for 15 or fewer drives I would normally use the Corsair 500W. That said, this is a good deal for this good quality PSU. After the sale, this PSU comes out cheaper than the Corsair 500W. So if you are thinking about a 15+ drive server, then this is a good choice. This PSU would also be a good choice if you wanted a 15 drive server that could support mostly 7200 rpm drives and some green drives (though it is still underpowered for a full 15 7200 rpm drives).
March 5, 201115 yr How does this PS compare to the Antec Neo ECO 520C? I ask because I got the Antec for $39.99 from Newegg just last week which ends up about $4.50 more expensive after taxes than this deal which ends up just under $40 after tax and rebate.
March 5, 201115 yr Author In terms of specs they are the same. The differences are that the Corsair has a variable fan speed, so the fan will spin down when not needed. Also the Antec doesn't come with a power cord. Given the choice between the two, I would probably opt for the Antec just so I didn't have to deal with a MIR.
