You need electronic engineer or similar, not electrician!

What you actually need is someone with the right experience, current job titles may not be clearly indicative of this :-)

As stated, he is an electrical engineer, not an electrician... excuse my phrasing. Shorted the two pins and i have power to the fan, so will i be able to check if im getting +5 +12 and -12 with the short before i plug the psu back into the machine?

Ta,

Damn this reply box behaviour, now it's recognising spaces but if I insert them higher up the reply it parses them as line feeds and initially ignored them entirely!

All wired up, voltages are good BUT we dont have a white wire (-5v) on the new psu, which we did have on the old one??

[magicniner]

If your PSU doesn't have all the right voltages it isn't the right PSU for the job, you could add a separate -5v fairly easily, but have you asked the manufacturer how much for the correct PSU for the job?

I think you need one of the older type ie AT not ATX http://www.ebay.co.uk/itm/AT-PSU-WOR...-/142163387623

I've pulled a power supply out of an old computer we have lying around, and ive managed to get it wired in. Now when i turn the m/c on the screen is coming up all stripey with a bunch of random symbols/ letters on it. Video card maybe??

[m_c]

Either the video card, or the video card is getting junk data.
You're probably better speaking to your board repairers, as now you know what the main problem was, and the machine is now doing something, it may help them track down what has been damaged.

I don't know the machine at all but if and only if it has a dumb monitor ie RS-232 it could be board rate set wrong with showing random symbols. If its a VGA type I take it you have unplugged the monitor and card and refitted.
