Where to purchase a new 250w ENP-3125 power supply unit in the uk

Go to this link and get one http://www.ebay.com/itm/New-250W-ATX-Power-supply-HP-Compaq-5187-1098-/360389017209?pt=PCA_UPS&hash=item53e8dbfe79

Do not try to fix this power supply. Better to replace with new or good used. I see many on ebay from 13.50 to 25.00. Also google that model for other options. Most likely fuse on the power supply has failed but if you bypass the fuse, with jumper wire or another fuse, will blow again. Probably capacitors. Good luck

I would put in a new power supply 250W is too little Wattage for newer Graphics Cards.

The only thing to do at this point is to replace the Power Supply with a KNOWN to be good, compatible unit, and see if the rest of the computer hardware components are okay.

Going by your information stated that the Power Supply is an Enhance ENP-2224B SMPS, (Switched-Mode Power Supply), it is a special shape.

If it wasn't for the Slim Micro-ATX computer case you have, you could use an easy to obtain ATX form factor Power Supply.

From a quick search though it looks like a replacement unit is affordable,

There is simply no way to tell if the motherboard, and/or Processor, and/or Ram Memory, and/or Harddrive, etc., is okay without having power.
Unless you transfer the components on the motherboard to another working motherboard.

[NOTE*
If your Power Supply has a rocker switch on the back that lets you use 120 volts, or 220 volts, make SURE it is set to the right voltage.

USA?
120 Volts
Europe?
220 Volts
Australia?
220 Volts
Japan?
100 Volts ]

Then your power supply is dead. You can purchase a new power supply relatively cheap. Give newegg.com a try.

Welcome I want you to help does not exist DC voltage reading was 1.5 disappear

Replace the power supply.

Chances are that 250w power supply is not going to power a motherboard with a 24 pin connector, but you can try.
You will need to purchase a 20 to 24 pin adapter cable.
