Hey everyone,

im fixing my friends eMachines 5220. Its pretty old now and the PSU has died. Ive already tried two psu's but one didnt fit and one didnt work. I cant find any that seem to be compatible. dont want to go ordering them if theyre not going to work because its a waste of money on delivery charges.

The voltages that ive seen on the side of the old psu were

Orange Red Yellow White
+3.3v +5v +12v -5v
12A 25A 12A 0.5A

Blue Purple Grey
-12v 5vsb P/G
0.5A 1.5A OK

If you need any more information, please ask, ive had this system for a wile now and i want to fix it asap!! lol

Thanks for any help given :D

Here you go:

You'll probably have to look around to find a matching psu.

ok, well ive looked at the links that ulysses posted. all of the 400w psu's that ive found have minor difference in voltages. the psu in the computer has the voltages
+3.3v +5v +12v -5v -12v 5vsb

the ones ive seen all have +12v1 and +12v2 instead of the -5v, would these differences in Voltages and amps make any difference in the computer working?

if anyone needs any more details about anything then please ask!
thanks

The -5 volt was eliminated when the new standards for atx power supplies were adopted. Your friend's older motherboard will require a replacement power supply with the older -5 volts

The two +12 volt rails maybe or may not be two separate rails. Sometimes it is an advertising gimmick and sometimes it is genuine. Either way it probably won't make any difference. If you find a power supply with the -5 volts, then it will probably also have only a single 12 volt rail.

We had a similar thread a while back. I seem to recall there was a source in the USA but I can't remember the name of the vendor. Maybe if I think about it for a while it will come back to me.

Sumvision power supplies are available at ebay in the UK but they are used psu's.

Note - use a UK search engine and search for: sumvision KY2300ATX 400 P4

You might have better luck than I did.
