RE: Dell Inspiron 3847 PSU upgrade

24 pins is EPS12V.  20 pins is ATX.

Power supplies that guarantee 150W combined on the 3.3v 5v rail and 15 to 20W on the +5vSB Rail  with 450W or more on the 12v rails would work.

This is why a Corsair CS750M is a recommended upgrade.

Systems that are 650W and lower that only have 130W on the 3.3v/5v rail tend to not work well if at all.

Systems with less than 15W on the +5vsb rail tend to not work well if at all.
