PSUs single 12v Rail or more?
I might be needing a bigger PSU than my Antec 430w, it has 17a on 12v1, and 16 on 12v2, total of 33a. The reason I am asking is that I just ordered a GTS 450, and it specs a minimum of 400w PSU .. and I want to add a 2nd HDD in the case, and not use the USB adapter on the 2nd HDD. I tried the 2nd in the case before, and had some issues upon boot, once I removed the 2nd HDD it booted fine.
I'll layout what I have on/in my rig:
Antec EA-430D
Phenom X3 8650
4x1GB DDR1066 (1.8v at 800Mhz, not stable at 2.0 & 1066)
Onboard GF8200 IGP (was a GF 9600 GT OC)
WD SATA 3gb 500GB
Toshiba SATA DVD+-RW
Chaintech AV-710
WD 500GB via USB to SATA adapter
160GB USB 2.0 Pocket HDD
Logitech MX518 Mouse
Dell Multimedia USB Keyboard
Logitech Webcam Pro 9000
HP LaserJet 1200 USB
I am going to install the GTS 450, and I want to install the 500GB. I can't find minimum 12v specs for the GTS 450. I know I am cutting it abit close with my 430w w/o the 2nd HDD, and 500+ would be preferable. But I don't know what would be best: Single 12v rail or more than one. I am guessing on 2 rails, one is for devices and the other is for PCIe power?
