another problem with my Biostar

**Darthv15** · February 19th, 2002, 01:52 AM

Hey guys, I have a Biostar M7VKS and an AMD 1.33 ghz processor. I posted a thread earlier but don't know the policy here, and i need help. I am running this off of a 200watt generic power supply. I have found that after shutting the computer down I am able to start it back up. In order to start it back up i have found that i must pull the wire for the on/off switch. So I figured there was something wrong with the switch right, wrong. I replaced the switch that didn't help and now I have replaced the power supply with another generic 200watt. Still not working the way that it should. I have looked at both AMD's website for documentation and Biostar's. Biostar says virtually nothing about this, while AMD does touch on it. Unfortunately in order to understand the documentation from AMD I beleive you need to be an electrical engineer. Any help would be much appreciated and if a bigger power supply is need could you explain why? Thanks a lot.

yes you need a bigger power supply 200 watts doesn't meet the minimum requirments nor should it be a generic brand

amd recommended power supplies

Yep, running an Athlon of that speed you need a bigger PS. At least 250W (if a really good one), preferably 300W. That should solve your problems. Kendos link from AMD explains all.

If you want the best price, check out the Doc's Deal's forum at this site, and posty a request for info about the best place to get a PS if you can't find it in the threads.

Hope this fixes it for you.

cheap way out

$29.00

That is case and all, about as cheap as just a p/s alone.

The deal about 250 vs 300 watts, if you're just running one CD-ROM/Burner, 1 Hard Drive and a couple of fans, the 250watt QUALITY power supply will do just fine.

The high quality p/s will give you STABLE voltage control as well as enough amps to load up the system on boot.

The AOpen 250watt I've suggested here is capable of 375 watt surge during boot, or at times when other devices are just starting up. This is directly from AOpens power supply site.
They state a 150% overload capability for short periods.

Cheap power supplies only weigh like 1.5 pounds, a high quailty one will weigh more than double that. Not very scientific method of comparing, just a measure of the weight of the internal transformer which is the basis of any power supply.
