I'm upgrading the PSU to something w/a little more punch. Not sure what I need for a proper PSU. Have a P.O.S. Antec 300W that doesn't even put out 300W. Was looking to get @ least a 480W. Maybe the Antec True 480. I wasn't going to get a custom built job. I WAS hoping to get one w/some adjustable POTS on/in it. Also WAS hoping to keep the price down a little. Didn't want to spend more than $100-150 bucks. Saw that Antec had a 550 TruePower w/a 5.25 baybus to go in your case bay, & has adjustments for the individual rails & the fans for the PSU. Not too expensive. My biggest problem is even when I'm not overclocked, my 5v is below 4.9 . So it is causing a big problem when I'm overclocked. Plus I have to increase the voltage on the CPU to keep it stable. So zouup, down it goes. Any suggestions will be greatly appreciated.
