hi
I have connected the components myself after reading the manual.

when I turn on power, nothing happens.
NO BEEP
PSU and CPU fan not spinning.no glow of LED on keyboard too.
ONL

a small LED on mobo glows. indicates that supply is OK upto motherboard.

what can be the issue?


note I have cooler master 430 n check image, I have not connected this.

Check the connections on your Motherboard. Also, check the headers of the Power.

yeah...m kinda confused with headers. but will that be an issue for no PSU and CPU fan spinning ?

Yes, only when the power of the Motherboard is switched on the PSU's fan will rotate.

Led on the Motherboard will glow. But only after you switch on Motherboards Power (via Power Button) the Motherboard starts working. So, first check the headers of the Power on the Motherboard.

so you mean you connected it originally.

and BTW those white connectors you left unconnected are for fan. put in molex there from psu.

removed 1 RAM , connected everything back including headers. have put a molex from PSU in that white pin from above image.

still the same, LED on mobo glows but no PSU and CPU fan rotating.

here is what i did

confirm the Headers plz

CM 430 has following headers, POWER , RESET , HDD , P+ and P-
here is how i added it


7-5 = RESET
3-1 = HDD LED
8-6 = POWER

now in 4 goes -P LED and in 2 goes +P LED

1. Motherboard fan can spin without any HDD
2. PSU fan will only spin when your motherboard kicks in the process of booting (motherboard fan starts spinning if you have connected the wire.)

Most probably you have some problem with motherboard connectors, start, restart, hdd light etc. Check if you have plugged em right.

try to short the on/off terminals with a metal bolt. If it works then fine else the problem lies somewhere else.

Your connections look right, a pic of mobo with conn will be helpful.
