I just got my SM X10SDV-2C-TP4F (flex ATX , 2core PentiumD chip, very similar to Xeon-D chips). And im a bit confused on the various power ports / options on the MB. ( after reading closely in the manual, i think i may be lucky i didnt fry my board already!)
According to the manual, that 4pin MOLEX power port (# 3 in my pict) is ONLY for powering a HDD, nothing more.
And in terms of powering the MB itself, you should ONLY use EITHER the 24pin atx (#2) OR the 8pin connector (#1) but NOT both (#2 and #1).
Does anyone have any info on this or realworld experience with these power options on these board types (ie what are you using to power it?). im pretty sure ive read other threads where users are using both 24pin and 8pin, as i was researching this board here on sth.
When i first got the board in, on my test bench, i connected both the 8pin and the 24pin to my power supply (as you would on a normal server type board). I then ran memtest for about 22hours, with no issues.
Then as a test i tried connecting ONLY the molex 4pin to my power supply (+ using one of those 24pin shorted pin13 plug/connectors to power on the psu). This worked! the MB power button would not work, but i was able to power on the board via IPMI and run memtest for about 20min (FWIW, the power draw was 4w less using this, ie 50w vs 55w when running memtest86 pro v8's load). im using a PSU i had laying around, a 650w psu, so its def. not efficient at these low load levels, ofcourse.
here is the relevant page from the SM manual for this board. (i find it weird that you are NOT supposed to connect both 8pin and 24pin)
thanks
