I have question if someone could answer please. I am trying to do this on my son's computer and he bought the corsair tx850m power supply. He also bought the tax adapter. What I can figure out is the 4 prong plug from the old supply which a schematics say it's 12v. The new power supply has a 8 prong plug plus the tax and all the perifial plugs. Can I plug half of the 8 pin plug into the 4 prong plug?
Any help would be great thanks.

cut the molex from the old lenovo supply up close to the the supply itself. Cut off the molex to the new power supply closer to the molex itself. Take one yellow wire from one of the power leads on the new PS and use it as the third yellow on the lenovo molex connector. You can always order another power splitter if needed they're cheap from amazon. But you will still be able to draw power from the motherboard itself as well to power hard drives. Splice and solder (or electrical tape, not the best but it will suffice) the wires together from the old lenovo molex wires and the new PS wires, four blacks, green, blue and three yellows to each other and bam, you have a working upgraded power supply using the old lenovo molex connector. My plex server is very happy with my five hard drives now and enough power to them.
PS I did not need the paper clip jumper as others have mentioned but you may depending on the type of power supply you are using. best wishes

Old post, but important to clarify. The 8-pin 12v power connector is for certain hi-power processors, and is actually two 4-pin connector interlocked together. You should be able to split these apart into two 4-pin connectors (and re-interlock if need be), use one and cable tie the other back onto it's cable. I would expected this is detailed in the instructions that came with the power supply, or on the Corsair website.
