Verge of hitting PSU limit?

[RTFMy]

Hey, I was talking to my dad today about modding in a 120mm fan blowhole in my case today, and he brought up my PSU, and I forgot about wattage, so i'm just wondering if I have enough left to add some more 80mm fans, a fan controller, and a 120mm fan and to stay stable.

Specs
NF7-S revision 2.0
AMD Athlon Mobile XP 2500+
512mb Corsair XMS (upgrading to 512x2 soon)
some 80gig harddrive 7200rpm (IDE cabled)
Xtasy Radeon 9800Pro 128mb 256bit
400watt ANTEC PSU
Volcano 12 HSF
5.1 headphones (don't think this matters, but just in case)

current fans : 2 (exhaust) 80mm case, 1 motherboard fan, 1 video card fan (prob gonna upgrade for overclocking purposes), 1 HSF.

my case : http://www.newegg.com/app/ViewProductDesc.asp?description=11-129-120&depa=1

what I plan to mod :

Looks like it got defaced, but meh all I have on my space is files.. lol
Actually I think i'll take a peek through the logs, cause I searched google for "ximilonx owns you" and found numerous other defaced sites dunno what jailtime would be for getting caught though.. It certainly isn't hacking cause any 5 year and his dog could do it if it were explained.

just about every fan you ever meet will run under 7 watts. most run 3 or 4 maybe. With only 1 hdd and a reletively svelte vid-card ..wattage wise.. doesn't look like a problem at all.

Just remember to connect all those fans on their own dedicated PSU wire. I've read recently that you can fry things, such as you hard-drives or other components, if you run them in serial on the same connection.

Is there a site or anything I can go to to calculate the # of watts I have left?
