Hello all,
i have a computer whose PSU (Power Supply Unit) was broken. I could have easily replaced it by anyother new PSU but the original PSU had a pretty unique 14 pin connector for the Motherboard instead of the usual 20 or 24 pin.
I googled the 14 pin configuration and luckily found the pin config. I had a spare 20 pin PSU, now all i had to do was to rearrange the pins so that each pin gets the correct voltage. i did that and now when i turn the computer on the power LED blinks ON and OFF (twice in like one second), the LED on the motherboard also blink the same way, like its turning everything on and off periodically. nothing comes on the monitor.
Please suggest a solution because otherwise i will have to abandon the whole CPU which will be a waste Sad
Other technical information is provided below:
14pin PSU pin config:

20 pin PSU config "Dell HP-145SNF":
- i had to modify the following things: the pins 3 and 6 (FAN OFF and FAN CMD) of the 14 pin PSU didnt make any sense to me so i gave nothing on them, they are disconnected. what to do with them?
- as only 3V was available in the new PSU so i had to give 3V where 3.3V were required.
- the unused pins of the 20 pin PSU were properly insulated from eachother.
- the power ratings of the new PSU is 152W and the old PSU was 125W. so its well over than what is required, the voltage was equal of both the PSUs but the current of the new PSU was more, so it should suffice.
- The fan Spins pretty good until the CPU is on standby, but as soon as i push my CPU power button, the blinking starts and the fan also keeps on switching on and off. dont know what signal to give at the pin 3 and pin 6. Please help.
