d975 boot probs - fairly newbie

[JCDC]

Hello

Im trying to get my d975xbx to boot – having a bit a struggle and think it’s the psu that the problem. Certainly need to eliminate any probs with the psu first I think..

I was told by antec that the psu that came with the case was compatible with the mb but im not so sure. Im in the uk if that makes any difference.
P150 PSU here: http://www.pcper.com/article.php?aid=23 ... pert&pid=4

Mb psu requirements are here: http://www.intel.com/support/motherboar ... 022070.htm

Currently I just have the 24 pin connected and 4 pin connected to the 8 pin. No 4 pin out from psu but i guess i can plug one into the psu easily?.

Theres a green led lighting on on the mb labelled “CR3J1" – always on when the psu is turned on. isnt taht the standby led indicating that power to the mobo is OK?

On power on - the fans turn. Memory leds flicker then cuts out.

Can anyone help me verify this or at least give some advice as to how I can figure it out myself? Fairly new to all this so any advice would be cool

Cheers

I also have the Antec P150 (http://www.legitreviews.com/article/352/1/) and use it on my system, which just happens to be using an Intel 975XBX and an E6700 processor.

I removed this power supply and installed a better (750W) power supply that had all the cables I need.

I'm not sure what CPU, GPU, and number of hard drives that you have, but the 430W prolly won't cut it. If a motherboard has an 8-pin header on it just remember it's there for a reason.

its so hard to know what to do - i mean went to my shop just now and said i want to get a new psu to try and he said 'oh no it definately wont be that" its probably your memory.

very frustrating.

the manual doesnt help much - i mean take the second diagram down - what the hell does that mean? is it saying dont use a converter?

rant over.

currently i have my 12*2 in and 2*2 in half of the 8 pin socket. i think i have an 8 pin socket which i can fit into the psu so may try that next.

thanks for the reply - glad to hear that someone else has a similar config up and running!

I've read a couple of places that the D975XBX/BX2 requires the 8-pin connector:

http://hardware.gotfrag.com/portal/story/33492/?spage=4

quote: "However, we cannot say that the entire installation experience was as hitch-free as installing the processor. After initial connections were made and we attempted to power up the system, it became apparent that something was wrong. After a lot of testing and a little bit of panic, we traced the problem back to the 12V power connector on the motherboard. Unlike most 8-pin 12V motherboards, the D975XBX absolutely requires dual 4-pin 12V adaptors, aka full EPS12V compliance from the power supply."

Good luck.
