Hi,
I have an original Pentium 233 MMX from the 90s that I'm using as my main retro machine. So far I've replaced the IDE hard disk with a CF card (after one of the two already died anyway) and added an external battery to the Dallas RTC chip.
So far, so good. The only remaining project for me with that PC would be to replace the old power supply, assuming that the capacitors are probably not in great shape after all these years and it's fairly noisy anyway - which is particularly noticeable now that the drive noise is gone.
Obviously, a PC of that age does not have an ATX power supply, but an AT one.
Now, who has experience with renewing the power supply on a machine of that age? Is it as easy as taking a low-power ATX PSU (like this one for example) and an ATX-AT adapter (like this one) or is there more that I need to keep in mind? At the very least I need a few more adapters, like power for the floppy drive, CD-ROM, etc, right?
I noticed that most modern PCs have the PSU on the bottom while the old PC has it at the top - is that potentially an issue when mounting it?
But would the mainboard adapter "just work" or is there anything I'm not thinking about but should look out for?
Thanks!
