This is a little besides Linux but I'll try to answer it
It "will work" sort of, but I do not recommend it. The extra four pins are to supply more power to the mobo and it may get underpowered not to talk of that the 20 pin PSU may not have the umpf needed
At worst you end up destroying your hardware
Go buy a decent 500 + watts PSU - and look at the amps on 12 volts - that's the critical part
Cost is probably around 100 $ US

Don't fix it if it ain't broken, don't break it if you can't fix it
