Ummm, I think your wrong. The 9800GT has a 400watt minimum according to factory specs. I had a 430watt in the machine and the card ran like crap....new or old games it didn't matter. Cut start-up down to 4 processes and services down from 48 to 26 along with firwall diasable and anti-virus disable before going to online game. Huge lag, ping spikes from 50 to over 200 plagued me until I got this 850w PSU.
Thanks for the link, feel like a dunce now LOL. My 430PSU had a clearly marked CPU plug-in, this Corsair does not so thus the confusion. Thanks for the help!
Actually, he's not.
Your 430w psu may have been crap or may have been defective, but a decent, functioning 430w would be more than sufficient.
