P/S requirement calculated

[PCHardstuff]

Below is my list of components and my estimated power consumption of each, assuming each component were operating at full load. Please look this over and let me know if it looks like I miscalculated something. It looks to me like I've got to get a Antec True Power 550 watt p/s. If I calculated correctly, I am going be almost at 75% load assuming everything were running at max load. I already have everything except the p/s.

Abit IC7-G w/ p4 3.0 200 watts?
2 WD Raptor Drives 30 watts
2 WD 120gb SATA Drives 20 watts
11 Antec 80mm LED Fans 40 watts
3 Sunbeam 12" Cold Cathode lights 12 watts
1 Sony DVD burner 11 watts
1 plextor premium burner 11 watts
2 vantec hard coolers 5 watts
Asus V9950 ultra FX video card 40 watts
Vantec 3.5" bay fan speed controller 5 watts
Audigy Platinum 18 watts
Corsair TwinX 3200LL (2x512mb) 5 watts
Lian Li 3.5" front panel LED display 5 watts
Floppy drive 2 watts

Max Load is almost never the case though. 550W for that setup should be plenty.

You don't HAVE to get a True Power 550W unit, the Fortron 530W unit puts out more power for less money.

my god... sure you got enough casefans there???
and 300W for the mobo and CPU is a little excessive.

IMHO a quality 420W psu should be pleanty.
i dont believe all those wattage figures, plus not everything is running full power at once, except for possibly startup and then its only for a few seconds.

I didn't say anything about case fans, try to learn how to use the forums, its not that hard even for a tech.
