My current PSU is dying. So i need to replace it soon. current budget is under $200.


Antec Nine Hundred(possibly a 1200 in the future) (

intel e8400 core 2 duo over clocked to 1.4v 4ghz

Palit 8800gt 1gb sonic not OCed (possibly will though)

2x 2gb OCZ reaper DDR2 1066

nForce 780i SLI

western digital caviar black 1tb 7200rpm

not the exact one but: Seagate Barracuda 7200.11 160gb


let me know if i forgot anything. The dying PSU is an OCZ gamexstream 850w. Using the Newegg wattage calculator said i need 567watts. so i want to get something 650+ and preferably modular.
i was looking at THIS PSU but i'm not familiar with the Kingwin name.was also looking at this one but i'm also unfamiliar with XION.
both seem to have good reviews.

A good 400W PSU can easily handle your system.

I would recommend the Corsair HX520 so you have some extra in case of upgrades.

^5 +1 what the animal said.

Corsair has a reputation for high quality power supplies that consistently earn high marks in technical reviews. They are stable and reliable.

The general rule of thumb is that a high qaulity 500 - 550 watt power supply can easily handle just about any single video card made. The reason power requirements for video cards are mentioned is that sometimes the video card uses more power than all of the other components combined. In your case the 8800GT 1MB card does not use much power.

thank you for the advice. i think i will follow theanimal's advice and get the 520hx. definitely within my budget. was thinking of using an SLI configuration with my card but apparently it is no longer sold so i don't have to worry about SLI anytime soon.

Another would be a Antec TruePower New TP-750/TP-650/TP-550 which is a newer and more efficient design. Both are SeaSonic built units.

I use the Antec quaddro 850watt and have had great results with it. The unit is over 80 certified and modular. If I weren't on a budget I would go with PC Power and Cooling, but they are not modular.

The PCP&C Silencer units are all also SeaSonic units. The new 910 is a M12D based unit but honestly I would get an actual SeaSonic sine they have a 120mm fan and are modular.

Thanks for the info Ancient_1. I didn't know they were SeaSonic. I also like a modular power supply.
