How can I test new K7s5a?

For the time being I have a K7s5a, xp1600, power supply, 256 stick of crucial DDR, a monitor and a GF2 GTS card.
Can I test the system so far with just these components?

I realise i'm missing some important parts (including a case), but if i put them together and try to post, will I get anywhere?

Thanks
 
why not?

i remember seeing some where that a ATX PS will start if 2 pins is short. (try to search some mod for adding an extra ATX PS)

or you can play around the PS SW on the board (jump it? connect it to a switch like the once in a case for on/off. I don't know much. But the switch is different that the AT form factor before)


(you miss hard drive and case, right?)
 
Thats what i figured. I tried it last night, connected it to the speaker of an old 486 and tried to fool the board into thinking the power button was pressed. It took me two tries to find the right pins to short (the manual was crap).

Once i did that the sys would start, all the fans would start (inc the GF2 fan) and the speaker would beep once. Then it would power down again.

I'm now pretty confused. I read online that 1 beep means either POST succesful or refresh failure. I've tried reseating the memory, using SDRAM instead and reseating the graphics card (if i remove it completely I get 2 rapid beeps then seven more). Am i shorting the wrong pins? Do i have to do anything else to get it to believe its on? or have i got a component prob.
btw, I'm using a Delta 300W PSU with 245 TCO.
thanks
 
You may not keep the PowerButton pins shorted. (The manual is absolutely precise about them btw, can't see why you say it's crap.) If you do, it'll power back down five seconds later. That's the override function should the operating system not react to the poweroff command generated by a short button push.

Peter, thanks. looks like i was too hasty in blaming the manual (although my complaint was over the differing labelling of the pins on the FPI connector in the manual vs on the motherboard itself - i got a bit confused 😱)

so what can i do to get this running? short the pins then pull it off once its running? will that let me test it?

thanks,
 
Well it's a pushbutton connector - power on by connecting them briefly, power off the same way. Best done with a leftover jumper.

regards, Peter
