PSU is working 100% with the system for two weeks. It's a new AMD box I've had nothing but trouble out of .. Anyhow, it's a 400w PSU. I took the intake fan off of the front of it for room for my case-fans, but that's okay because I have two 80mm fans blowing into the case right above it. It gives better intake than that other fan ever did. Anyhow, from time to time, my PSU will stop powering external things. It'll stop for about 1-2 seconds, all the fans will turn off, and then turn right back on. This is probably a sign of an overused PSU? Maybe I need a bigger one? Or maybe I should plug some of my things in externally? The PSU will just cut power to everything but the mobo, cd drives, and HD. Post back with any experiences or answers.. ;) Thanks.

Did you remove the fan from your PSU? If so, are wondering why it isn’t working correctly?

the PSU fan keeps the PSU from overheating and really doesn't do much for cooling the case.When the PSU overheats it stops working when it cools down it works again. Might I suggest putting the fan back.In order to cool your case a front low intake fan with either1 or 2 back high(heat rises) exhaust fans like AMD recommends is best. This produces the necesary movement of cool air that will be used by your chipset cooler/fan to cool the AMD chip

a link is below you should goto. Its about correct airflow in cases. A fact that is not commonly known is, If fans are impropely placed than they can work against each other. Be sure the the fan is in the power supply and it is blowing air out and not in. you want the air to come in at the front. copy and paste the below to your browser http://www.heatsink-guide.com/casecool.htm

I heard that it's usually better to have exhaust fans than intake fans. The reason being that intake fans might just swirl the hot air inside of your case around, and not help it reach the exhaust fans. If you have exhaust fans, they'll suck the hot air out, and the cold air will come in from the edges of the case and your one intake fan...

I haven’t seen Naomi post back yet but if she took her fan off the PSU and her problem is intermittent shutdowns, it seems pretty obvious to me what the solution should be.

Check all of your connections Naomi. This problem can also arise from shorts on any of the cables from the PSU.
