Assuming Sandy Bridge, it comes in 4 TDP's 95, 65, 45 & 35W, and I cannot think of any H61/H67/P67 that doesn't support 95W. Kinda the same with AM3.
Regardless, if your MOBO doesn't support 95W then you'll need a new CPU from the MOBO's 'CPU Support List'. Go to the MOBO site, look up your MOBO and then look for supported CPUs.
