well after i have been through countless power supplies.

overclocking these AMD"S is tough on a power supply.
I want to get some oppions on the best power suppy made.
I ordered a new PC POWER & COOLING 510 watt unit with custom built with remote adjustments on all the supply lines.
i have been running 550 antec's but they have disappointed me latley.
so what do you guys think are the best supplies out there?
