You need to replace the power supply on an old computer, but the power supply has a unique shape that you’ve not seen before. What’s the best way to handle this replacement?

A) Purchase a 3rd-party power supply that is close to the same size

B) Contact the original manufacturer for a replacement

C) Move the motherboard to a new case and use a standard power supply

D) Buy a 3rd-party power supply and mount it on the outside of the case

E) Start a new web site: oddlyshapedpowersupplyowners.com


The answer: B) Contact the original manufacturer for a replacement

Although today’s computers tend to use standardized power supplies, some older systems used proprietary and uniquely-shaped power supplies that are matched to the motherboard. You can’t directly replace the power supply with a standard model, and the best choice is to contact the manufacturer for an exact replacement.
