Need a bit of Help here

Ok ... heres my system Specs

AMD athlon 64 3500 Winchester (Actually will be a 3800 venice Next week)
Asus A8N-e Nforce 4 Ultra Motherboard
1 Gig Corsair Value Select DDR 400 kit 2x 512
1 DVD Drive
1 CDRW Drive
1 300GB Raid Stripe from 2x160 GB WD Sata Drives
1 120 GB IDE Drive
1 40 GB IDE Drive
1 ATI x850XT-PE Graphics Card
1 Soundblaster Audigy Mp3 Sound Card

How here is the Dilemma
I had an Antec True 430 PSU before and it worked Flawlessly in my previous system which was
AMD Athlon 64 3500 Winchester
MSI NEO 2 PLatinum
1 Gig Corsair Value Select
1 dvd Drive
1 CDRW Drive
1 120GB IDE drive
1 40 GB IDE drive
1 ATI X800xt AIW
1 soundblaster Sudigy Mp3

During the upgrade i thought I would need a new PSU as the 20 pin connector for the True Power didnt fit at first (Dont ask i didnt read the manual) and I ran out and bought a NeoPower 480

Fine everything installed great and the system seems stable.. HOWEVER
Ive noticed that When i run 3d mark 05 i get my best scores when i "plug out" the 2 ide hard drives... Im not talking minimal improvement either.. Im talking 300+ points... Im now starting to Wonder if i bought the right PSU for this Rig... Ive been trying to do the PSU consumption Calculator thing and at full load its looking like ill only have approx 8 amps left on the 12v1 Rail after everything else gets their share... Compounding the problem is the fact that i cannot find the max load power requirements for the x850xtPe

Can someone please help me verify that im not starving my system in the PSU dept ? Any expert help would be appreciated.

Thanks

maybe windows is doing something with those harddrives which uses cpu power? indexing? iono

Somehow i dont think thats the problem as the indexing service is off on bothe ide drives .
