I just finished building my first PC but there's one issue, when i hook up the monitor there's no signal, everything else powers up, fan turns on but the motherboard speaker gives of 1 long beep and 2 shorts, I've heard that means it has something to do with the graphics card but the graphics card is brand new. Could it be that my power supply isnt strong enough for my specs?

Specs
MOBO: Gigabyte GA-970 D3P
GPU: Radeon HD 6870 1GB DDR5
CPU: AMD FX-8320 8core 3.5ghz
PSU: Dynex 400w
DVD: lite on 24x
HDD: Seagate 1tb 7500rpm
RAM: 2x 4gb dual ballistix RAM


Something tells me my PSU isn't strong enough for those specs someone please let me know, and I've tried some things already such as removing 1 memory stick and moving the GPU to a different slot
