Antec, Cooler Master, and Thermaltake are well established brands in the computer power supply market. In this article, we'll be examining some of their high end power supplies catering to users with multi-core and multiple GPUs. The participants include Antec's Signature 850w, Cooler Master's UCP 900w and Thermaltake's Toughpower CM 1000w. They will be strapped to our new power supply test system and will be evaluated on efficiency, noise, ripple, and voltage regulation.
Corsair has a great reputation for being one the leading performance memory module companies in the industry. They are the providers of some of the fastest memory around, and it is no surprise that when they made the foray into the power supply market, they offered high performance units in the HX-series. Continuing the HX-series legacy, Corsair now offers the VX-series. Touting the VX-series as having "the industry's most efficient power management" and "rock solid performance", we'll see if Corsair can live up to these claims with the VX550 550w power supply.
On the test bench today are two power supplies, Antec's EarthWatts (EA-500) 500w and Seasonic's M12II 500w (SS-500GM). They're both 500w power supplies, and in many ways they're the same, but also quite different. With one marketed for users who want a value priced energy efficient unit, and the other for gamers, I'll take a look at what sets them apart.
Antec's EarthWatts power supply is constructed of plain steel. It has a very plain look to it, which fits well with it's placement as a value power supply. The Seasonic M12II on the other hand is painted black, giving it a sleeker look, especially more enticing if your case has a window. The M12II is a little longer than the EarthWatts, putting the lengths at 16cm and 14cm respectively.
