PSU help needed urgently

Ok so I'm building a system on a AU$2000 budget.... here's what I've got so far but the out of the box power supply isn't gonna cut it...

Case: Honli ATX 9638SB Black Case with USB/AU port 2 CD door and 550W [HLC-9638SB] 1 35.81
CPU: Intel Core 2 Duo E6400 - 2.13GHz - (1066FSB/LGA775/2MB Cache) 1 345.57
DVD: Liteon SHM-165P6S 16x DVD-Rewriter Retail 1 51.48
Hard drive: Seagate 320G 7200RPM SATA-II 16M cache [ST3320620AS] 1 145.00
Mainboard: Gigabyte GA-965P-S3 supports Core 2 Duo [GA-965P-S3] 1 199.00

Special Components: None + 0.00
Discount: Amit Approved - 6.00
TOTAL: GST Included: $167.71 $1844.86

into this I am adding a surge protector and then several options I'm trying to get advice on now...

the first is moving from the E6400 to the E6600
and the second is upgrading from the 7600GT to either a 1600XT or a 7900GS

selecting all of these options is likely to blow my budget by a few hundred $$ but I'm considering it anyway (how often do I get to build a new PC after all)... for the PSU I'm not sure if I can get away with a coolermaster... here's the 2 I'm looking at:

CoolerMaster 430W eXtremePower PSU [RS-430] $79.00

and
Antec 450W Smart Power 2.0 [SP-450] $111.00
http://www.antec.com/ec/productDet [...] odID=14450

I know antec has the most solid rep... but I'm hoping to prevent major budgetary overflow but I don't want to get something crappy...

any ideas?

dude? how did you know where I was buying my PC?

hehe scroll up... the antec smartpower 430 is 111 and is the one I decided to go for with the 7900GS and the E6600... my last PC I spent a month designing and with only one RAM upgrade and a new harddisk managed to last 7 years at a price of 1800 in 2000 lol....
my monster: P4 2.4 (400fsb) on a asus p4s8x I believe with a ti4200 a burner a rom a floppy a wd80gb caviar hd (bolstered with a 120 later on) 2 fans a 400W PSU (generic due to my ignorance) and 512mb of ram (upped to 1gb) oh and an SB 5.1 oem lol


I'm thinking that with this new rig I should be able to last another 4 or 5 years easy... given that my 2.4 rig only just discovered games it couldn't handle (oblivion and civ4) and that's more from wearout given it's run almost 24/7 for the last 6 years... I'm not sure but I think it might be the most veteran PC I've ever known lol

u need 35-45 amps on the 12v line if upgrade your card later. if not then 30-35 amps min.

u should get 1950 pro card or low end 7900. go with the e6300 put more into the gpu and psu - i build systems. get a good overclocking board and run the 1.8ghz chip at 2.6-2.7 ghz it will run super cool with stock intel cooler - i know i use e6300 at 2.67ghz and it rocks!!!

i run a 4 drive raid 10/0 4 segate drives raid 10 is xp 4 drive raid o is vista rc-1. 2 gigs of ocz 3-3--3-8 ,533mhz,1.8v at 2.1v 4-5-4-15 and 800mhz ram runs cool.

learn to push the ram and chip and spurge on the psu and gpu!


get a silverstone, hipro - antec is ok but it may be low on amps
