Antec TPII 550EPS12V or Cooler Master Real Power 550 power supply???
Does anyone have any experiences with either the Antec TPII 550EPS12V or the Cooler Master Real Power 550 power supplies? They both are rated at 550 watts, with ATX 12V 2.01 and EPS 12V 2.1. The Cooler Master has a power output meter and a blue fan, so I am kind of leaning towards it. any comments on either model??? tks. - brian |

Depends whether you want power/known-good or style The first thing to note is that the Antec has one huge 12V rail, and the CoolerMaster has a 3-way split. This is due to EPS12V 2.1 spec requiring that all PSUs comply with IEC 60950-1, which essentially stipulates that there should be no lines capable of supplying more than ~220W. This limits the 12V rails to 18A each. The CoolerMaster only does 30A on the 12V, so should (IMO) have gone with an 18A/12A split. Instead they went with a 12A/12A/6A 3-way split. Given that even a 2-way split causes problems with some dual-processor boards, I'd be very cautious about using the CoolerMaster in such a situation. The Antec shows complete disregard for the safety regulations and will happily pump out 36A from a single 12V rail. This can be a bad thing if something gets close to shorting out (400W of energy being pumped into anything is generally bad), but also provides marginally better rail stability. As far as the actual power outputs go, the Antec has a slight lead on the CoolerMaster. Additionally, it's known to be an incredible power supply, capable of running pretty much anything (dual overclocked Xeons? No problem. SLI? Doesn't even notice). I'm using one at the moment to power a dual Duron system; a complete waste of the power but I'm intending to keep it for my next major system upgrade (whenever that occurs). The Cooler Master has less of a track record, having only come out last month, but certainly looks a lot nicer and is quiter than the Antec. However, unless you're building something that actually needs such immense amounts of power (or reliability; I'd definately choose the Antec over the Cooler Master for a server), either PSU will do the job fine. At which point it comes down to which one suits you better and the prices involved.
