Hi every one, heres the prob.

My computer switches on for a split second and then switches off. I can see all the fans are spinning and all cable are connected in that split second. It was working perfectly the day before and now it doesnt want to seem to work. I have to completely take out the power cable to switch it on and have another go. The motherboard light is on so it seems to be gettin the power, so im stumped :(.

System specs are : Asus P4S800D, P4 3.00 Ghz S478 , 4 x micron pc2100 256mb , 160gb diamond max 9, msi 6800 128mb , enca 400w psu with 12A on the 12V line.

Any help would be really appreciated!!!!!!

thanks!

Do you have another PSU you can put in the rig for testing? My first thought is it is either the mobo or PSU.

This has worked for me to isolate the problem: Unplug everything, hard drives etc. and only have power to the motherboard and monitor, it should post then if not then it is PS or MB. If it posts then hook up one item at a time and find where the trouble is.

Not familiar with the sites you might buy stuff from. Good inexpensive PSUs:
Fortron 450W
or this
Fortron 400W
Get the 450W and you will be able to use it for your next build.

Let me know if you need to have PFC or send me a link to the websites you like to buy from over there and I'll take a look.

hi thanks for all the help.
My m8 can get me a EZ cool 450 watt clear box with l.e.d blue lights in it.

would 450w be adiquate for this rig?
its ratings are :

5v-28a

12v-30a

3.3v-26a

is this a good deal? he wants £30 ($50).

thanks!

Never heard of EX Cool, so I can't comment on its performance or reliability. I would stick with a good, reliable PSU mfr - the PSU is the heart of every PC. That being said, 450W is more than enough for your rig. A good 300W PSU would be enough for your rig.

yeah thats enough power for your rig, but do not buy a psu based only on appearance. Do a little homework, check out tomshardware reviews, or accortech, etc. The specification stickers on psu's generally aren't all that accurate as it's the manufacturer that is the source of the info.

A general rule of thumb however,
if it's less than $50.00 it' probably isn't great.
oh, and weight often is an indication of quality as far a psu's are concerned. More weight = better components.

Either of those FSPs I linked are good PSUs at a great price. I do agree that you don't want to skimp on PSU, but you don't have to spend an arm and a leg to get a good PSU.

Quite right, a good 300 would work OK for now. A 400-420 will take additional video cards, etc. I've had several 400-420's under $50 that had excellent 12v ramping:All these are good except the cheapie on this page. I use Antecs because they have lots of extra molex leads :)
