Some manufacturers have proprietary designed PSUs which are non ATX form factor, the case of the PSU could be of a different size, or the 20 pin connector could have a different pin out. If you let us know what the make and model of the computer is and the make and model of the PSUs we can determine if it will be compatible.
Another option here would be to purchase another PSU for the computer, that shouldn't be too much of an investment for a new to you computer. The PSU is the heart of most computers, it's worth while knowing yours is going to work properly. There are computers out there that I will not mention...emachine...which have a reputation for a combination failure, if the PSU goes out it usually takes the motherboard out as well.
Family and loved ones will always be a priority in my daily life. You never know when one will leave you.
