Hi there
With the new RTX 3080 out, they recommend a 750W power supply. The HP Desktop PC - 870-290NZ only has a 500W built in.
My questions are:
1) Would the built-in power be enough to use a RTX 3080?
2) If not, is it easily possible to upgrade the power supply and are there recommendations?
Thank you in advance!

The 500W supported the GTX 1080 (180), but the RTX 3080 (320W) is a 140W gain. A 500W can not handle it.
You need to make measurements.
1) The RTX 3080 is a very lengthy card. Can it fit?
2) Both EVGA and Corsair have 750W modular PSU's. Both are slightly longer into the case.
