it is 450 wats. the pc is a HP desktop model h8-1140sc. the bios is locked and as such i can not configure it myself at all.
what does Motherboard timer not operational (check all PSU to MB connectors seated) mean.
450W from a no-name cheapo PSU (usually cheap units are included in pre-builts) could actually simply not have enough power for a Nahalem i7 + 960. 960 might be power efficient but first gen i7s were quite the power hogs so if you say your system uses about 300W of power with efficiency of 75% that means that the PSU has to actually draw 375W. if you factor in capacitor degradation and that the PSU cannot output (if it ever could) 450W anymore it could be the issue.
Check all the cables that it has connected - Sata power cable, 24/20-pin motherboard cable, 8-pin CPU power and PCIe power connectors (should be dual 6-pin). If all cables are in place make sure nothing else is loose (GPU is properly inserted in the PCIe slot, RAM sticks are properly inserted, everything) and try again
EDIT: DSG pointed you to something I forgot - check if the 12V rail(s) of the PSU have enough Amps for the GPU. if it's a multi-rail unit. make sure to use 1 PCIe cable from both rails as to avoid overstressing 1 rail.
