How big of a power supply do I need?

[dwango]

I'm building a semi-new system, and I'll have the following:

Inwin Q500 case (w/ included 300w PSU)
6 case fans (including 4 YS-Tech 120mm's)
TBird 1.33ghz AYHJA-Y
EPoX 8K7A+ mobo.
existing GF2, SB Live!, and EE Pro/100 NIC
512 MB PC2100 from Crucial.

IBM 75GXP 45GB, IBM 60GXP 40GB, and a WD 13gb hdd
2 optical drives, and a floppy

With that, I'm assuming I'll need a larger PSU. Should I go for the 431W Enermax?

(P.s. Sorry if this is the wrong forum, I didn't really know where to post this message. ):D

Just say no to emermex :D They are awsome power supplys BUT some people with just the 8k7a and 8k7a+ have problems when paired with ememex psu's. They say that antec 400w psu's get the job done, might wanna take a looksy. I belive there around 80 or so not sure.

Can you explain like what type of conflicts? (system won't boot, etc)?

I would wager it is a 3.3 and 5 volt issue. My Enermax 431 is a great PSU , but I had to do the 5 volt mod and the 3 volt AGP mod to get it to run stable. I couldn't afford to buy a new PSU.
