I would try a cheap one first , a used one . But I would n't buy anything under 350 watts .


I like this site ,while not rocket science it does give one an example .

'k, sounds like you fried the PSU.

Depending on how good quality it was it may have done some damage to your system.

If so, the only way to determine what may have happened is get hold of another PSU, perhaps an old one for now, and try it with a minimum of hardware connected to the mobo.

Just the GFX card and the Mobo at first, and then try adding drives and stuff if it posts, and so on. If you connect something and it stops posting you may have fried that part.

As I recall my brothers computer wouldn't even post after he fried his PSU, until we removed the floppy.


As for what new PSU you should get, go for a good brand, like Fortron or Antec true (I know the former is excellent, and the latter is a favourite with the crowd here).

I wouldn't buy anything below 400 watts today.

This may help, tho' it's not entirely accurate, I think.

And it only shows you how much you need if everything is working at full power at once, and that never happens irl. So that gives you the biggest PSU you might possibly need, but you can buy something rated a bit below the wattage you get from the site.

Snny and Peat,

While that calculator may be (semi) useful, the problem is that there is no standard for determining the output of PSUs.
Basically, a manufacturer can claim anything they want.
A good test is simply to pick up the PSU...the heavier the better.

I don't think it's possible (awaiting the flames) to buy a decent unit for under $75 anymore.

Good advice clocker . My mentor or fellow computer buddy says that all the time . Its like 16 or 22 gauge steel . "Peat just feel the weight ,and pick the heaver the better." I' pay a little more attention to PSU 's now when freinds ask about a system. That Slaco site I metioned , I'v sent 20 people from freinds to work mates to him. At first three had power supply problems . After that I questioned him on his choice of case's and psu 's . Now when he sees me I ask for a better brand of psu and another case fan. Even tho they bought new and it's under warranty they called me and bitched ! :lol:

That's why I also recommended specific brands.

Fortron's like the best manufacturer on the market, so when they say 400 watts, they bloody well mean it.

Well, at least they come close. :unsure:

And I still wouldn't get something without having looked at a couple of reviews as well. I think I posted this (http://www.trustedreviews.com/article.aspx?page=2279) one a while ago regarding relatively cheap PSUs.

Jeantech looks good. :unsure:
