Hi all,
I currently nearing the end of my build, and found an 8 'pin' plug from the power unit spare. Can anyone tell me what it is supposed to be for please?

There are usually 2 types of "8-pin" plug in a PSU (it depends what brand/model you have).

You have either the CPU ATX12V/EPS power (for the motherboard), which comes either with a full 8-pin *or* a combined 4+4 pin; or the PCIE power (for the graphics card), which comes either with a full 8-pin *or* a combined 6+2 pin:

The options are as said above me, CPU or PCI Power.
Since that PSU is not brand new and likely old, chances are it's PCI Power, because in the past CPU Power was a 4 pin connector.

Hi,
I have my graphics card plugged in via 2x 6/8 pin plugs which you can unplug at the power unit and the graphics card, and my motherboard is plugged via a 20/4 pin plug fixed. My drivers are plugged into the power unit via a 8 pin plug into the power unit and the other has 3x L shaped plugs, this fixed black pin plug is confusing me.

It's most likely the CPU since everything else is plugged in, it should say "CPU" on it's side, if you're still not sure, snap us a pic.

You don't necessarily have to plug all the cables that come with your PSU.

Some PSU's have extra PCIE cables (for 2-way/3-way multi-GPUs). So if you only have a single GPU, you would have another PCIE cable as spare.

Some motherboards require 8-pin, some 4-pin, some both 8-pin and 4-pin (just half of the 4+4 pin cable).

Those 3x L shaped plugs you described are the SATA power cables (used for SSDs, HDDs, and ODDs).
