Keep in mind that these wattages are taken at the wall for the entire system containing an Intel QX9770, 2GB Corsair, RAM, the video card(s), 3 WD Raptor Hard Drives, a DVD/CDRom, a floppy drive, and a Koolance Exos water cooling system. We used the new BFGTech ES-800 to power our systems. With that in mind, if you have an 80% efficient PSU, you can take the wall wattage and multiply by .8 to see what your PSU output would approximately be. So in the case of the 4870: 359w x .8 = 287w. This roughly shows that the PSU is actually outputting around 300 watts of power.

dan kan je het zelf wel uitrekenen
je hebt genoeg
