Would my PSU be able to handle this processor upgrade?

[Jango]

I am quite sure that my Asus P5N-E SLI motherboard can support a Q6600/6700 LGA775 65nm Core 2 Quad processor but I am not sure whether my PSU would be able to handle the upgrade. I will also be upgrading the heatsink to a Freezer 7 pro, would my PSU be able to handle that?
Here are the details on my PSU sticker:

Is my PSU good enough for the new heatsink and processor? My current processor is a E6550 Core 2 Duo 2.33Ghz.

definately, nothing to be worried about

I wouldn't trust it after googling the model. I'd get this instead.

What about upgrading the processor without upgrading the heatsink? Would it overheat and would my PSU be able to handle it?

Without a new heatsink surely it would take up less power. Wouldn't it?
