HD6870 needs 500W PSU. Those cheap ones are not suited for gaming.


BTW, did u clean install the windows?

Make a run outside of the PC, with only CPU+FAN + RAM + GPU and PSU with connection to the LCD to see if it starts the BIOS.

All that installed to your mobo that is sitting just on the paper box it came in.

It should boot in to BIOS.

ok i will try that, looking at that psu it doesnt have the two six pin connectors my 6870 requires. also do you think it is possible that my cpu or mobo has been damaged by the new psu?

Hardly. The PSU is not a good one. Unless it did the collateral damage, it should be fine.

CPU is the most quality part in the PC.

And since it is spinning, I thing it is just the PSU.

Can u reset the BIOS?
Reset the CMOS memory the right way as is described in the motherboard manual using the clear CMOS link with the power cord unplugged.
And when the battery is out, press the power button to discharge all the electricity from the system.

Do u think that the CPU could be the culprit?

They do go bad too, but that's rare.

as i said in my original post i did smell burnt electronics when i turned the power on for the first time, but if thats the case that would make two in a row. Do you think i should see if newegg will refund my psu for credit towards a better one? Which psu would you suggest? will newegg rma my cpu again? i should still be within their return period.

Do you think the mobo is fine though? I mean that the psu didnt damage it.
