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. (


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!
