Power Supply Help...

[Smith]

These are probably the stupidest questions in the world...but I just bought
this thing and the Use Manual wasn't in the box (can't contact them until
Monday about it) so I have to ask as this is different from any power supply
I've used before apparently. This is an older power supply, I needed an ATX
1.3 with the aux power connector for my year 2001 model Gateway computer.
It's a Fortron, FSP, whatever
(http://pcpartscollection.com/fspfs40siled.html) power supply.

Well the first question is that black nob in the second picture. It spins
like a volume control nob, one side is a + the other a - . I'm guessing it
has something to do with fan control? Also, there is no voltage switch.
Every power supply I have ever had has had one, is there a reason there
isn't one on this model? I have to wait until Monday to contact them about
my manual, was hoping maybe someone here would know something? I don't want
to hook this thing up until I understand it...

the specs say 115/230 volts

some of the newer devices do not require a switch so it should be fine

and yes, the knob is to adjust fan speed

Okay, that's great, thank you so much. I've been waiting to get this to
support my new video card and really wanted to use it this weekend
