BleepingComputer.com: Built New Computer - Wont start!

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

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

Okay thanks for the help Pauline
