A10-7800/H50-55 PSU Replacement - 20 pin ATX to 14 pin ATX adapter

Hello everybody!

I bought a new graphics card (Radeon R7 250) and PSU (EVGA 600W Model No. 100-W1-0600-K1) for my Lenovo A10-7800 H50-55 desktop.

 

What I didn't know whas that the motherboard uses a 14 Pin ATX plug. The PSU that came with the computer is a HuntKey HK280-25FP (180W) which also uses a 14 pin ATX plug. This seems to be an unusual format, as most PSUs I looked at had 20+4 pin ATX connectors. Even the HuntKey website lists their comparable 180W PSU as having a 20+4 pin ATX connector. (http://www.huntkey.com/en/products/d499/index.html)

 

Unfortunately the HuntKey website does not list the HK280-25FP, so I thought that because most of their other 180W products use 20 pin connectors, so did the HK280-25FP, and thus my Lenovo H50-55 would use a 20 pin ATX plug. The hardware manual for the h50-55 DOES NOT specify how many pins the power plug on the motherboard has.

 

I did not know that my Lenovo used a 14pin plug until after I bought the power supply and attempted (unsuccessfully) to plug it in. I have found a variety of 20-to-14 pin ATX adapters on the market, my question is if anyone here has used any, if their are any they can recommend, are their any that work well? Thank you!

You can buy an adapter cable from Moddiy or Amazon:  Lenovo-H50-55-upgraded-to-GTX-1060-graphics-card-and-Corsair
