Rail 1 or 2 is just the 4-pin CPU plug only, on that PSU model.Originally posted by: Zebo

Excellent posts. I just bought a Enermax EG375 (370W) dual +12v rail PSU. Plenty of juice on the +3.3v (30A) and the +5v (32A)... but I'm questioning the +12v rails. 12v1 (14A) and 12v2 (13A). Here's why: just put in a MSI GeForce 6600GT AGP card (replaced my nVidia MX400). System runs perfect in windows... and in 2D.. Even COD runs flawless; however, when I run 3DMark01/03/05, video freezes and system locks up.. it doesn't reboot though. I started disconnecting +12v components until I only had my boot HD and 6600GT powered.. still froze. My question is: does the AGP slot power off the same +12v rail as the CPU... or the other 12v rail (HD/opticals/etc) ? I used a dedicated molex called "Extra" to power the 6600GT.. but not sure which rail it hits?
Started getting message (from nVidia control panel) "video card cannot draw enough power.. adjusting...."

Replies greatly appreciated....
It's about 50/50 power draw. The plug you plug in to card is the second rail.
Rail 1: is both mobo connectors (20/24 pin and P4/or 8 pin)
Rail 2: is all molex/floppy connectors
You problem is rail 1IMO.. but why guess? get a fat single 12.
OP: If the A7N8X-LA is similar in design to the A7N8X Deluxe in that there isn't a 4-pin CPU power connection on the motherboard, rail 1 or 2 is technically unused. In that case, your system is pretty much running off of one +12V rail in total. To make matters possibly worse, that Enermax model (old) could choke and/or shutdown @ full load according to SilentPCReview & TrustedReviews. Therefore there's a possibility you have even less than 13 or 14A altogether.
Sorry
