If your PSU has only an 8pin, you can still plug it into the 4pin.

Edit: NVM thought you were talking about 4 pin power outlets for fans.

It would boot, but it'd be pulling all the power through the main 24-pin ATX cable.

im using an h50. my 8pin wont fit into the 4pin because there are capacitors surrounding the 4pin. It will only be for about a day, i gotta load windows onto the drive, and thats all ill be doing tonight.

if i dont have the four pin power plugged in to my mobo it wont even post, for some it is required to power the cpu, the main 20+4 isnt wired in to the cpu.

i might be wrong but that is what happens with my MSI board

Well my understanding was that that P4 connector was added by Intel back with the Pentium 4 processors because the chips were drawing too much power for the PSU to supply through the 24 pin connector alone.

To that end, try it out. You might get lucky as long as you're not running a full load on it, but it will probably be unstable.

Most PSUs let you split the 8 pin in half for boards that only use 4 pins, so check the connector if that'll work for you.
