Good day the community!
I have recently received my new power supply, i was very excited for it and just finished installing it.
But i have a problem, it's the same problem i had with my Cooler Master GX Lite 500w, it won't boot up! i have already asked the community about my other power supply, they suggested me buying another power supply and there you go! My newest power supply is a Sharkoon WPM 600w ATX.
I have installed it correctly, the 4-pin cable, 20+4 motherboard cable, SATA cables on my Disk Drive and Hard Drive, and the 6 pin PCI-E cable to my graphics card.
After succesfully installing my power supply, i tried pressing the button to turn my computer on, but... nothing would happen.
I have although noticed the green LED turning on my motherboard, but that's all, no fans are running, nothing is powered up. I have tried everything, plugging everything out and back in multiple times but it wouldn't help.
I know you guys have more experience than me and i'll be honest; i am desesperate, those were already 100$ on both the powre supplies, i don't want to waste anymore on my computer, but i will surely buy more RAM.

If it helps, my motherboard is a ASUS F1A55-M LK R2.0, i forgot what my processor is but i am sure it is 3,00ghz and i have 4 of RAM on my computer.

Thanks alot!
Have a good day.

Can you provide a list of all components in your computer including the case itself?

Please follow these instructions exactly as I wrote them. Make sure the computer is completely turned off before you start.

1. Turn off the power supply with the IO switch.
2. Unplug the power supply from the AC outlet.
3. Unplug all components from one another. The motherboard should not be connected to anything. The PSU should not be connected to anything. The HDD should not be connected to anything. GPU, RAM, and CPU should not be attached to the motherboard. All case wires should not be attached to anything.

Once that is done, attach ONLY the following. Nothing more.
1. Attach the 24-pin motherboard power connector.
2. Attach the 4-pin CPU power connector.
3. Place the CPU on the motherboard. Plug the CPU fan into a motherboard fan header.
4. Attach the CPU Cooler.
5. Install one DIMM of RAM.
6. Find the power switch cable on the case. Plug it into the F_PANEL. If you don't know where that is, open up the motherboard manual book and find the diagram of the motherboard. It should label all parts. Anyway, it's located in the bottom right corner, just to the left of the big blue SATA port. The top row of the F_PANEL has 4 pins with one missing on the far right end. Plug the power switch cable into the 3rd and 4th (left to right) pin in the top row. That should leave two pins to the left of the switch and an empty slot to the right of the switch.

From there:
1. Connect the monitor.
2. Plug the PSU into an AC outlet.
3. Switch the PSU on with the IO switch.
4. Click the power button on the case.

What do you see? Any POST? Does the CPU fan spin?

You probably already have done all that, but I just want to verify it. If it doesn't work, please leave the setup as is. Do not add or remove any components.

Thanks for the quick answer ksham!
I have done what you told me to do, step by step.
After i was done with it something happened, the fans of both CPU cooler and the PSU ran for about 1.5 seconds, but then they stopped right after.
I am impressed, and surprised.
Thanks for that, but it didn't work :(

Okay. Again, I would prefer you leave everything in the same state that I left off on so that there's no misleading results. From there, make sure your computer is shut down completely. Do you have another computer around that works? Try to borrow one RAM module (any size, doesn't have to be 4GB) and replace the RAM module in your motherboard with it. Then try turning it on again.
