Recently i replaced my mobo, gfx and ram.

The refreshed config looks like this :

MOBO = Abit KN9 (nf4 ultra)
GFX = Sapphire X1600XT (256 MB ram)
RAM = 2 x KingMAX 512 MB DDR2 @ 800 MHz (dual channel)
PSU = Chieftec 400W (forgot the markings, if needed i'll get them)
HDD = 250 GB Maxtor
DVD/R = Pioneer DVR-111D

The question : a friend of mine strongly advised NOT TO CONNECT THE REMAINING 4 PINS on the power
motherboard connector. He told me that this will lead to CPU/mobo overvoltage and subsequent failure.

So, scared of burning anything, i decided to connect only basic 20 pins. I was told that some earlier mobos
had this problem, especially the AMD with 7xx pins (all i know is that this number starts with 7).

I'm worried this may pose a big problem later if i decide to do some OC or add more HW on mobo itself.

What to do ?

Does it work? Leave it as it is, although if the mobo has the 4-pin connection, it's there for a purpose, i.e. to plug the power connector from the PSU

That would have to be an extremely badly designed mobo for such to happen. As long as the voltages match, nothing should happen.

Thanks guys !

One more thingy : i have the AbitEQ monitoring s/w. It's looks lame (the whole DeLuxe design sickens me)
so i also tried a freeware SpeedFan util.

It reports 12V rail at 6.05V !? WTH is going on !? BIOS says all voltages are OK. Also searched for
infos on HMonitor and found it has also the same prob.

Is Abit KN9 THAT new, so no monitoring s/w can report correct voltages ?

Might actually be 12.10.

Look for the divider settings on the monitor software.
