12 volt rail

Does the 420 ps-375 watt have 1 or 2- 12 volt rail,the manual says 2 but the
last time I open the case I thought I seen 1.I bought a geforce 8800GT and
it's got 2 cables (2 wires on each cables connector)so if it has 2 12 volts
I have to buy 2 Y adapters.I hope I'm making sense.

The power supply connectors are found here;

Hi!

but the last time I open the case I thought I seen 1.

You won't be able to determine that unless you open the power supply and
look, and even then it may not be obvious. A "rail" in a power supply is the
path that power takes as it is regulated to the proper voltage levels. If
you have two twelve volt rails, then you have two separate sources of +12V
in that power supply. This can help when trying to power especially heavy
loads that might otherwise be too much load for one regulator and it
supporting components to handle.

maybe I only have to connect 1 six pin,this is a 8800GT,from what I
understand the 8800GTX requires 2 six pin connections,am I right,I didn't
get any manual or instructions with this card.TIA

Mine needs one six-pin and one eight-pin connector. There are no converters
from standard 4-pin connectors to connect to it. Luckily, my Thermaltake
power supply has detachable cables that do the job.
