Well, without overclocking, core 2 quads don't really draw much power even in heavy benchmarks at full load. Pentium 4 is the least power efficient socket 775 intel cpu.

Core i7's like core i5 can consume quite a lot of power at full load, even over 200W but not 400w.

If you make crazy overclocks, maybe you can draw 400w peak. For a typical user without liquid nitrogen? No..

Yes core 2 quad 9650 extreme is a sick processor, it can draw crazy amounts of power under high oc.

Quote: The first thing we notice is how full load power consumption quickly increases to almost uncontrollable levels when pushing above ~4.25GHz.
In fact, we found achieving true stability any higher nearly impossible with water-cooling alone.
