What if i'm missing the ATX 12V 2x4 cable?

post #1 of 8
Thread Starter 
I've bought a new mobo , and i went to install it today.
However I wasn't even thinking of whether my PSU was capable of handling the new mobo... It's missing the ATX 12V 2x4 cable.. I believe my psu only has 2x2 cable and it can't fit the mobo obviously.
What if I leave it out and just connect the 24pin ATX cable? I mean I know it's a stupid question , i know it won't work , but i'm just wondering , can i try it?

wont work, the 24pin is for the boards power, the EPS (ATX 2x4pin) is for the CPU. so if you dont plug the EPS in then no boot, just fans and LED's. there is also no "safe" way to make a EPS plug either. ive seen some people who have mistaken a EPS for a 8pin PCI-E and try and use the 4 pin that comes off the 24pin plug for some reason... but this will fry stuff nice and crispy. get a new powersupply, if you dont have EPS then your well over due for a upgrade

So when buying a new PSU I should look for EPS in it's specifications?
Because i've been searching already and didn't find any ATX 12V 2x4 in psu specs , only ATX 12V 2.3 or something?!

Are you sure it won't fit? Most boards can use 4 pin instead of 8, just half the socket won't be used.

However, since your cable is 2+2, it may be incompatible physically, but I'd give it a try.

Hmm i've just tried it , it fits on upper socket , leaving 4 lower socket holes empty , but it fits correctly... Should I try to fire it up like that? Could I fry the new mobo?

You will be fine.

Most PSU's will either come with a single 4-pin, two 4-pins, or a 4+4 pin. As long as you have the single 4-pin, it will fit and work correctly, even in an 8-pin socket. You will get better power delivery and a higher overclock with a true 4+4 or two 4-pin connectors, but for small overclocks or basic usage, the single 4-pin will allow you to use the machine.
