I recently purchased parts to build a new computer and after finishing it up, it refuses to turn on, I think it is because of the PSU and motherboard.

Antec Basiq BP500U 500W Continuous Power ATX12V Version 2.01 Active PFC Power Supply
GIGABYTE GA-990FXA-UD3 AM3+ AMD 990FX SATA 6Gb/s USB 3.0 ATX AMD Motherboard

I think it has to do with there being no 8 pin connector from the psu or something, only two 4 pin connectors if that makes any sense.

I have been reading the motherboard manual and next to ATX_12V pin #4 it says GND. I think this means I have to buy some sort of modifier to make my 4 pin connection into an 8 pin one?

Hi Dave,

From the picture you linked it looks like there are 4 pin connectors for the CPU power...two in white casing, two in black

Click on the picture you linked to bring up access to view connection setup

This shows that the motherboard has an 8 pin power connector, but the PSU has no 8 pin to put in it.

The 4 pin will work on some motherboards but even if the motherboard works with the 4 pin you are only providing half of the current carrying capacity which would be provided by an 8 pin. I would say yes, get an 8 pin cable or modify to an 8 pin
