3rd gen i5 3550 question on wattage of processor

Hi,

My question is this, does the wattage on these processors only come in at 77w? I don't see any others here on this site, but I have one that the box it came in claims it's at 95 watts and when I put it in my Gigabyte Z77x-UD3H MOBO the fans spin but the BIOS never runs. Is the processor not compatible if it's 95 watts? Could the processor be dead or the BIOS corrupted? Please help.Gigabyte site says these boards are compatible with 77w processor. Wondering if my  Intel box is mis labeled.

Thanks, Mike
