IdeaCentre 700: 10-Pin power supply PSU connector / adapter?

2015-12-01, 1:56 AM

Just bought a new IDEACENTRE 700 - 90ED0009US from Best Buy and I would like to upgrade the anemic 250 watt power supply but noticed I have a 10+4(cpu) pin connection to the motherboard. I have found 24 to 14 pin but nothing of this sort on the boards. Anyone have any idea on adaptors or the pinout of the 10 pin so that I can make my own?

hi jegillis,

 

Welcome to the Forums.

 

I don't have the pinouts on the 10pin connector that's used on the IdeaCentre 700 motherboard but I looked around the net and you're right, there's no one selling a lenovo 24pin to 10pin ATX adapter cable yet, however, I have high hopes that this cable should work:

 

PSU Main Power 24-Pin to 18+10-Pin Adapter Cable (30cm)

 

I would recommend you contact the seller though to ensure compatibility.

 

 

Let me know if this works for you.

 

Regards

I did some digging and it appears that  the gray PS_OK signal line and Purple +5v was removed with a different order on the pins, the keys for the connector are the same so I could just get a 24 to 14 and chop off 4 pins and put the wires in the correct place.

 

 

The wires are as follows

I tried this as well and could not get it to work.

 

I have a Lenovo 300s, which came with a 10 pin motherboard power connector, 4 pin power connector, and a 200 watt HuntKey PSU.  I bought a 400 watt Kentek TFX power supply and the 24 to 10 pin adapter.  I rearranged to the wires to match the Huntkey.  Unfortunately, the computer would not power on by use of the button.  I tested the Kentek with a mutlimeter with the adapter on (shorted green to black) and confirmed the power supply worked.  

 

I have been researching this the last couple of days and still no luck.  Please let me know if you were able to make it work.

 

Thanks

Same thing here I was unable to get the power supply to start up. The only wire not on the 10 pin that is on the 14 pin is the +5v and power supply ok. The only thing I can figure is that PS on is not pulling down when pressing the switch?

Well I got it working! I shorted pwr_on and ground in the connector with a paper clip, power button works like normal and I can shut down from windows. Only issue I see with this is you would not want to power any drives as it appears the power supply just stays running and the MB manages the power.

Had anyone tried the cable from the first response to this post yet? Or has anyone gottenit to work without using a paper clip to short it? I'd just use the paper clip if it was my computer but it's my wife's
