I have an old IBM Aptiva 2153 that I would like to replace the PSU by swapping one in another box. The current bad PSU in the IBM is a 95 Watt PSU. Would you think if I switched it with a 200Watt or above PSU this would work/be safe? Are the PSUs on these old computers proprietary to the one the manufacturer put in? I would like to save some money by not having to spend $40 on a replacement part for this old computer. Please let me know what you think. Thanks!
