While not as mighty as its Noisetaker 600W PSU, Enermax's 535W still has enough output for a powerful SLI system. It has a connector for anything you can find in a PC, with four SATA power leads, seven standard four-pin plugs and two PCI Express for graphics cards in SLI mode.
It has two fans to keep the graphics cards and processor cool, and is extremely quiet. The box also contains a six-pin to four-pin 12V adaptor, so you can connect it to older motherboards. It's a quiet and powerful power supply and excellent value.
