In short, basically this is a 680 Watts PSU, completely ready for SLI GFX solutions (only two PCIe connectors though) and multi-core (server) systems. The PSU itself is build in accordance with ATX12V Version 2.2 and EPS12V Version 2.91, including 8-pin 12V connection specification ( newer PCIe 2.0 power design). If we look closer at the voltage rails for a minute, we see there's nothing to complain about either.

Let's focus on the important 12 Volts rails as there are apparently four of them. Four of them rated 18 AMPs per rail. There seems to be some enough leverage as the +12 maximum combined load in Wattage can be pushed towards 624 Watt.

As stated these four separate 12V circuits each are rated with a 18A to ensure the stable distribution of the power requirements of your high-end gear; yet there is some xtra reserve: 4x (18a x12v) = a 864 Watt calculated peak.

To get you a broader overview, one GeForce 8800 GTX/Ultra draws roughly 10A maximum. Two 8800 Ultra's would not even itch this PSU with a peak, though the PSU would chuckle a little. However we are bound by the two PCie outputs this PSU has. Why then 4 rails ? Likely one for mainboard internals (CPU), one for your peripherals (HDDs) and two dedicated for your graphics cards.

Some other distinctive features are as mentioned, the USB ports (with one charge port for your moblie), low-noise LED colored fan, nice blue or black colored PSU with mesh design all over the chassis, sleeved lengthy cables and the fact that it is a very silent PSU.

Though the PSU is not modular, there are some options to connect, disconnect extra cables thanks to a (less favorable) T-splitter connector. Also worthy mentioning, the Molex plugs are all based on 'EZ-grip' design (easy to connect/disconnect).

Cabling wise you'll find:

• x1 24-pin mainboard connector
• x1 PCIe 6-pin
• x1 PCIe 8-pin (+8 to 6-pin adapter cable)
• x2 Floppy
• x7 Molex
• x1 P4 mainboard connector
• x1 P8 mainboard connector
• x4 SATA
• x4 Molex t-splitter
