Hi,

So my mobo uses this PSU dell ac290am-00 which has an 8 PIN mobo connector and 4 PIN CPU connector.
I bought this today EVGA 500 W1
I went home and tried to install but i'm missing 1 cable.
I found a cable labled CPU which has 8 PIN so I used 4 PIN only and it fits into the socket.

But then that was the only 8 PIN cable in the box. The other cables are PCI-E and 20+4 PIN.

Then i read another thread that says I can use a 4 PIN cable to power the board.

So now does that mean the same cable that powers my CPU can also power my motherboard? In other words, 4 PIN plugged into the CPU, 4 PIN plugged into the mobo?

I plugged the PCI-E cable into the 8 PIN mobo socket and that didn't power on the mobo. I was terrified so I plugged the old PSU back and now my computer turned on. So I guess I didn't fry the board.

I attach the picture so you can see what i'm talking about. Thanks in advance.

Are you suggesting me to buy a PSU with 2 EPS cables? If that's the case then I'll just stop by Fry. I just want to make sure not to return this and end up buying something else unnecessary. Thanks.

I ended up ordering the 24 pin to 8 pin connector power adapter. I didn't know such thing exist. I wish I googled this earlier instead of going to fry and bought the PSU that has 2x 12v connectors
