I am not sure if I have said this before, but the power supply in your PC is the core of the entire system. This is the one area you don't want to skimp on when it comes to quality. You may know I personally use an Antec High Current Pro 850W Gold for my test system. The new Antec High Current Gamer M series units have the same pedigree.
The Gamer M series is offered in 400W, 520W, and 620W models and all boast the same hybrid modular design as its HCP big brothers. To ensure the PSU either makes no noise or at least not enough to notice, you'll find a 135 mm two ball-bearing fan controlled by Antec's Thermal Manager and CircuitShield. In other words, the fan will only be used as needed and only fast enough to keep the PSU well within heat tolerance. This is further complemented by 100% Japanese caps and other high end components which don't produce a lot of heat to begin with.
The High Current Gamer M 400W, 520W, and 620W are available at an MSRP of $89.85, $99.95, and $119.95, which to be honest is my one issue here. If these units are built anything like my HCP 850W then they would be a great core to any build; however, there are similarly spec'd units on the market for less. If the MSRP turns out to be $15 to $20 higher than retail, I will be putting these at the top of my short list of PSUs to buy.
