[H]ard|OCP found a 700W PSU from Sigma which proved to be far superior to the unit they reviewed just a little while back.  At 700W it can handle most hardcore gaming systems needs, and [H] has no problems recommending this particuar PSU.  Give them a visit and see what you think of it.

“Sigma is back with a high powered computer PSU coming in rated at 700 watts this time. If you are an enthusiast thinking about installing some of the newer more powerful GPUs, a 700w rated PSU or something thereabouts, should be on your list.”
