[daroliaking]

I have following specs

AMD HD 6870
core 2 quad q8300
750GB HDD
4 gb DDR 2 Ram
G31t-m5 motherboard
lite-on PS-5251-7
win xp sp3

The graphic card runs fine
BUT
When i run games like Prostreet, GTA : EFLC , GTA san an, etc the monitor gets turns off (no signal)
I have to restart my pc.
Sometimes restarting pc also dont work
I think i need a new psu.
Tell me a psu or any other solution if available for this problem.

I will overclock my GPU only if needed.
Stock clock rates would be fine.
Just tell me PSU which is cheap and good.

Also note

CPU temp = 48-50 degree celcius (at idle)

I am ready to change my fan speed.
Should I set it to 100%?
I dont care about noise.

I am building a new pc with the same card as yours. I was taking the aerocool 600w which is not so expensive, but as 6870 requires 2-6 pin connectors, it was not compatible.

Finally, i took a 700w aerocool to power up my card......Hope it helps...

Thank you everyone

I found out the actual problem was with my by cable.

Since I had only 1 slot to put AMD power cord i was using a by cable.

I just saw that it was broken uo .
I will get a new by cable now.

Thanks ;D
