Looking for a new PSU for my old Optiplex 990
As the title says, I'm looking for a new PSU for my old Optiplex 990, but I'm not sure if the 24-pin power connector and the 4-pin power connector of the 0D6H9T motherboard are compatible with the ATX standard or if I would need an adapter.
If I need an adapter, what type do I need?

it is 990 SFF mobo
24/4 pinout is standard but the form factor of Dell psu is not standard.
