8-pin to 4-pin CPU Power Connector Issue

post #1 of 13
Thread Starter 
Yesterday I bought AcBel R8 Power 607W PSU. It has a 20+4 pin power connector for mobo which replaced my old 20 pin one & worked fine & a 8-pin power connector which I didn't know how to attach since I have only 4-pin CPU power connector on my mobo. I tried to attach the half of the 8-pin but the PC didn't boot up.



Please Advice

You will need a 4 to 8 pin adapter--but honestly what you really need is a more modern standard PSU.

Thanks for your fast respond. I don't know what to say AcBel have a very high quality PSU. Now I'll be search for the adapter.

You shouldn't need an adaptor, that PSU says it comes with a 4+4 pin connector meaning it should split in half.

It's not like an adaptor is going to perform any magic either, this connector is really simple. One half is 12v and the other half is ground. The only difference is one has 2 12v's and 2 grounds while the 8-pin has 4 12v's and 4 grounds.

edit, oops

Don't get an adapter because it would apply too much power to the CPU 4-pin port. Just use the CPU1 4-pin plug of the 8 pin connecter that is coming off the PSU for the power.

Since he already tried splitting it I thought an adapter might help...

Not all 8 pin PSUs have split adapters either...

You can't apply too much power to the CPU 4-pin port. You just supply the correct +12v voltage and the component draws what current it needs. You can't apply too much voltage either with just a +12v and ground. You will have +12v, a short, or an open.
Once again...
