PSU help :)

Heya all my son won a pc at his local college but the psu is only 250w and he'd like to upgrade it if possible.
The only problem we have is that it is in a horizontal case and pc world think they're hard to come by. We've been looking at various websites but can't seem to find what we're looking for . Does anyone no if it is possible to upgrade a psu in a horizontal case and if so what do we look out for at the various websites ...... thx for any reply :)

Open the case and physically measure the PSU casing. How easy it will be to replace I don't know but should be possible.

It is possible, but unless your son needs to upgrade other parts, such as graphics, there is not much point, as it is obviously built to work with a 250w psu. To upgrade the psu unnecessarily is a bit of a waste.

is possible to upgrade a psu in a horizontal case

Yes, no different from a PSU fitted in a tower.

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.
3 The correct connections for your equipment

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.

3. Correct connections
Some boards have 20 pin connectors others 24 pin
There is often a 4 pin plug required to power Intel CPUs
Molex D plugs for IDE HDD and CD/DVD drives
SATA power connections for latest HDDs and DVD drives.
