Is my PSU ATX 4-pin connector reversed from the standard?












1















I just got an EVGA 750 GQ power supply. The manual mentions that it includes a ATX 20+4 pin motherboard cable. However, the 4-pin connector appears to reverse the pinouts from the 4-pin plug on the motherboard.



Here is a picture of the male EVGA 750 GQ connector:

Here is the male connector on the old power supply:
enter image description here



You can see that the pins are reversed compared to the EVGA power supply.



Here’s the female connector on the motherboard:
enter image description here



Wikipedia seems to indicate that the connector on the old power supply is the standard: See picture from https://en.m.wikipedia.org/wiki/ATX
enter image description here



I was wondering if anyone might know why the pins might be reversed on this power supply? Is there a name for this “reversed connector”? And is there a way to adapt the connector to make it compatible with my motherboard?



...



Update:



This is a Lenovo TS140 branded box that I am attempting to upgrade. It has a 4-pin power connector and a 14-pin power connector.



enter image description here



I was planning to adapt the 20-pin power cable to the 14-pin plug with this adapter, which specifically mentions the TS140 motherboard.



As for the 4-pin, it actually does fit, if you tilt it at a right angle. Upon further research, there are similar comments about the connector not fitting, but being able to rotate it.



I have not yet tested this configuration, as I am waiting on the 20-pin-to-14-pin adapter, and I so am unsure about whether the system will power on.



Is the 4-pin connector on the Lenovo motherboard proprietary? Any guidance would be appreciated. Thank you.

  • Judging by the Google Image results for "ATX 20+4 pin", I'd say your old power supply has the wrong plug. Is this a custom desktop or a branded box you are trying to upgrade?

    The picture of the female connector on the motherboard appears to be of the wrong connector. The correct one is actually part of a single 24 pin connector on the motherboard, i.e. on the motherboard it is a 12x2 connector, which from the power supply is a 10x2 + 2x2 connector that gets married together.

  • Please, using better lighting against a neutral background, and your camera's 'macro' setting, photograph the 4-pin power supply connector next to the 20-pin connector, with the latches on each connector up, and then click on edit and upload the new picture. Then, take a picture of the connector on your motherboard, and upload that as well. What is the make and model of the motherboard, anyway?

Upon further research, I have discovered that that Lenovo motherboard and 14-pin power supply is totally proprietary.



I will do more research later to discover the best way to adapt the standard ATX 20+4 power supply to the proprietary Lenovo plug.

  • Just to follow up, I was able to adapt the ATX 20+4 pin standard connector to the 14-pin proprietary Lenovo connector using this adapter: amazon.com/NEORTX-Power-Supply-Adapter-Lenovo/dp/B00WE5KSFQ I was also able to connect a 12-volt supply from the PSU (labelled as CPU) to the 4-pin female connector on the motherboard pictured above. This had an 8-pin connector on the PSU, but the cable was split into 2 4-pin connectors. Plugging in one of these 4-pin connectors into the 4-pin female connector on the motherboard worked perfectly. The computer boots and seems fully operational.
