Question Can i adapt a 20 pin PSU connector to work on a 24-pin ATX connector?

[Gollot]

Hello, I'm trying to build a small form factor PC for emulation and maybe as a home theater PC. Most of the emulation that I plan on doing it on MAME and that emulator benefits the most from the CPU so I won't be using a high voltage graphics card. My problem comes from the case and the PSU, I found a working HP D530 PC on a working condition, my idea was to build a PC with an I3 9100f (That I already own) and use a Gigabyte H310m which looks that is going to fit perfectly on this small case. The problem is that these small cases have very specific PSU and any other kind of power supply won't fit on this case, this one works and is 325W and from the results on the PSU Calculator, all the components that I plan to use shouldn't draw more than 220W, I noticed that the PSU has a 20 Pin connector and the Gigabyte H310m has a 24 Pin connector, is there a way to make an adapter? Or maybe use a Molex to 4 pin adapter to fill the missing pins?
Thanks for your time and apologies for my rough English, let me know if I can provide more info.

Thanks for the recommendation, but unluckily that case is extremely overpriced (Around 250$ USD in my country for some reason...)

Hmm... How many forums am I going to see this posted on today?

Using a power brick with a PICO PSU is a MUCH BETTER idea than using that antique, proprietary HP PSU.

Lol, I post on various websites to get a wide arrange of answers. Thanks for replying, can you recommend a decent 300W or 250W Pico power supply?

If things are overpriced and not always available in "your country", how would I know what power bricks and PICO PSUs are available in your country.
