8800GT - Question about power

[altmann]

How important is the second rail going to the 8800gt? Will I be hosed if I don't connect it? Is it REQUIRED or is it there just in case? I know this may be a nub question but if you could let me know I'd appreciate it. I'm running a 520watt PSU.

What second rail? Do you mean the power connector that comes with the 8800GT? Where you can plug 2 molex connectors into one PCIE connector?

 

[altmann]

er... yea. that's what I meant.

Yeah otherwise it beeps and moans and screams, it won't hurt it if you leave it out, your computer just won't start.

Umm, if you leave it out, you'll see what I mean, not a nice sound it makes.

But yeah, you'll have to plug it in to use it at all.

the only issue here being that... I didn't use the 2 into 1 molex connector, and I'm wondering it just one 4 pin is ok or do I need to use that dual one for sure...

depends on the PSU.

I used one for my 8600GTS on a 250W Shuttle PSU, and the 8800GT uses about 30W more power than an 8600GTS, if it isn't wailing loundly (you'd know), I'd say you're in the clear.
