Check This PSU Calculator Prog Out

[lettuce]

Was trying to work out what my current rig PSU should be, so came across this program, http://www.extreme.outervision.com/psucalculatorlite.jsp

I have a 400Watt PSU for my current system:

AMD Althon 64 x2 4800
3GB DDR RAM
120 GB 7200 HD
300 GB 7200 HD
7900 GTX
4 FANS
3 USB Devices
Floppy Drive
DVD-R Drive

That calculator said i require a 414 watt PSU!!! Then i checked if i had bought the correct PSU for my new build, i have bought a 520 watt PSU for

C2D Q6600 (will be OC to 3.4)
4GB DDR2 RAM
500 7200 SATA HD
7800 GT
4 FANS
3 USB Devices
DVD-R SATA

it told me that i require a 618 Watt PSU. Surely this calculator is way off, well im hoping it is??? What results do you get??

Well i call BS on it, as it states that going from a stock q6600 to an OC @ 3.4, it requires an extra 169 watts!!!, That cant be right can it??
