250 watt is low under any circumstances, I'd upgrade atleast to a 450 or higher, around 650watt to be extra safe.

How to use ATX-250-12z SMPS with 24 pin


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.

Power on is ok but when switch off not ok


They are lightly loaded and WILL take time to bleed off the charge on the caps.

Also switching power supplies MUST have a load on them or they MAY overvoltage.

Hmmm.... mainly you have:
-20 or 24-pins connector, that is unique and goes directly to motherboard (powers motherboard and its components)
-4 or 8-pins connector that powers CPU
-the rest would be connectors for ROM (CD/DVD/BlueRay) and HDD devices (there are: molex and sata power conectors)

If you totaly unshure, there is manual:

Smps problem circle 600 watts


id say stick with the highest power supply you have, try replaceing the CMOS battery. also if your video card requires a PCIe power cable and there isnt one you may want to try that. this may be as simple as a bad 24x ATX power jack or the 4 pin on your mobo....which of coarse means Get a new mobo or have it fix with the warranty.

If computer is not powering on then open u r cpu and check the SMPS i.e Switch mode power supply which converts AC to DC it gives a output of 5v & 12v in that the 20 pin or 24 pin connector which is connected to the mother board remove that and short the wires Green and Black and make sure to remove all the power connectors i.e,hard disk,Cdrom or cd writer or DVD writer or any other device and one more connecto which is a four pin connector which is connected to the mother board please remove and test the 20 or 24 pin connector by shorting green and black and behind the smps u have a power cord of ac 220v just plug it and switch on if smps fan rotates that means it's fine then the problem willbe on the mother board just try this
