Acer N50-600 PSU Upgrade Issue, 4-pin connector not matching new cables

kyserkess · February 6

Hi, I have several very long cables connected to my PC and I think it's what is causing the PC to hang and sometimes crash, so I want to update my PSU. I purchased the Seasonic Focus V4 GX-750 (ATX3) - 750W for my Acer N50-600.

There's a four pin connector on the motherboard that none of the new cables match. There is a 24 port on the motherboard that one of the PSU cables connects to, but the other 4-pin connector doesn't have a matching cable. I tried connecting one of the new cables with the extra pins not attached, but in every case, the computer will not fully boot up.

I removed the all of my memory to test the beeping indicator and that part passed. I saw there is a LP4 Molex to ATX 4 Pin I can purchase, but I worry that could fry the motherboard. Is it true that there is no way to upgrade the PSU on this model? I would hate to throw it in the trash.

I hope someone can offer me a solution.

The below tables are the deceptive list of all the ATX power mobo plug pins for the N50-600 desktop and also the oem Acer fitted PSUs that work with your desktop, the new Seasonic PSUs could have different 24pin pin layout as the board should just work with the 24pin main plug plugged into the N50-600 mobo 24pin plug, If the 24pin of the Seasonic PSU is not the same then you have to change them and fins out what the Seasonic 24pins are so that it works with your N50-600 desktop mobo. Good luck and hope this helps you out.
