Tagan PSU - Split or combine?

[Neken]

I've recently replaced my PSU for a new Tagan Modular 580W (TG580-U15). I have an NF7-S motherboard and wondered whether the switch on the back for the 12V rails should be combined or separate? Or doesn't it matter?

Cheers!

What does the aforementioned PSU power?

Hi,

The NF7-S board
XP-M2500+ (1.65V, 2200MHz)
2x512MB PC3200 RAM
ATI R9800Pro
3x Hard drive
1x DVD-RW
1x DVD-ROM

Think that's all

You both have pci-e cards so I think that means split it

Dragging up my old thread... I now have a nice new Core 2 Duo set-up to put together.

E6400, P5W DH, 2GB GeIL RAM, 2x300GB HD, X1900XT.

Based on the above posts, I'm guessing it should now be changed to separate?

How do you know? I have just got one of these. My GPU is a Radeon x1800xt 256mb.

*Bump* *Bump*

Any clarification anyone, please?

With a GFX card with a high power draw like the X1800XT/X1900XT you'd be better with seperate rails

Split for a single graphics card system

Combined for SLI / Crossfire

Ta and Ta - off building I'll go

So if say i was running my single x1800xt with my PSU on combined, could this cause any problems? (IE: Crashing, graphical errors etc)

Edit: The guy from Overclockers who replied to one of my webnotes said:

"If you have just the one video card then it will be better to have the combined
rail"

now im intrested.

1 graphics card = combined i think ?
2 graphics cards = split.

or is it the other way about as i have been running in combined mode and my x1900xtx has been drawing about 30-35amps when in 3dmode....

and my 12v rail has been droping to about 11.97v-11.94v
if i run in split mode wont that reduce the ampage even more

i dont even understand why the 580w psu is running down into the under 12v line as 35amps should be plenty for 1 graphics card.....

and im hopeing when i buy the x1950xtx that this psu will also run it fine or im foo***ked :/
