They're called the Antec Smart Power 2.0:
I find them to be crap because I bought the 400W after my old power supply fried and I soon found out that this Antec power supply was meant for the garbage. This power supply couldn't handle running my computer for more than 5 min at a time, it would simply over heat and turn off if I let it go for longer than 5 min.
So I went back to the store today to get a more powerful power supply thinking that 400W just wasn't enough to run my computer. When I got there and asked to exchange it, the guy told me that this type of power supply is only meant to run the most basic computer (motherboard, 1 HDD, 1 drive, no fans, the basics).
I believe the reason is always overheated was because its got a thing in it to try save power. It saves power by only turning on 1 of its 2 fans all the time and it only turns the other one on when the power supply is just seconds from overheating.
So stay away from this type of power supply. But Antec still has good products, I ended up leaving the store with another Antec.
