Power Supply Shopping

Hello once again,

I am slowly resurecting an Asus Pundit-R Book sized PC. Next on the list is a power supply unit.

The part number is DPS-200PB-138C, made by Delta Electronics.

I have found these guys: click here who didn't reply to my email and one on Ebay which is the same apart from one letter and claims to be for an Elonex Prosentia.

Oh, and lots of people in America who have them in stock!

My Google arm is knackered, anyone know of a specialist or pattern supplier? Anything that would fit in the box would be great at the moment!

Thanks, Epirb.

I would measure the physical size of the power supply before you start and try to get one the same size with at least the same wattage.
Whatever the size is you should be able to get a replacement from somewhere in the UK.

If renewing a PSU check:

1. The physical size of your PSU, some are hard to replace due to being a non standard size.
2. The amount of power need from the PSU don't skimp

1. Physical Dimensions

Besides the specs and form factors, the physical dimensions are also important factors in selecting a compatible power supply. Here is an outline of the physical dimensions of most standard power supplies:

# ATX: 6x3.5x5.5", HxWxD. Most common. Uses 4 mounting screws.
# Mini-ATX: 5x3.5x5", HxWxD. Rare size. Uses 4 mounting screws. Can be used in a regular ATX case, but often not the other way around.
# MicroATX: 5x3x4", HxWxD. Use 3 mounting screws. Not interchangeable with ATX or miniATX.
# Flex ATX: Even smaller than Micro ATX. Various sizes according to case specs; often not interchangeable.

Use the data above to determine if a particular power supply would fit your case.

The quality of a power supply can be estimated by its weight. While this is not a true scientific or thorough measurement of the power supply reliability, it is nevertheless a very simple and easy way for ordinary PC users to estimate and compare the quality of a power supply.

The original 200W PSU was woefuly inadequate for these mahines.

Thanks for your input, I have bought the one that was available on Ebay, they are rare these PSUs, so rare noone wanted this one except me.

Fruit bat, you are obviously very informed on your PSUs! Would just say though that we are talking about a computer that at two years old crossed the atlantic in a yacht and then had twice the voltage put up it that it was expecting, not suprising it went pop and I would not describe it as 'woefully inadequate' for the work it was doing.

Brgds, Epirb.

When you say the PC had "twice the voltage put up it that it was expecting", did the original PSU have a voltage selector switch on it which was inadvertently left on the 110v setting when 240v was applied?

If that was indeed the case it may well be more than the PSU that has gone pop.

yes phono, thats exactly what upset it!

Oh dear, was it a spectacular pop? I'll keep my fingers crossed for you that it was only the PSU which fried.

Keep us informed as to the outcome and once again, best of luck.
