Mining+ +?

[Cajmo]

So I'm designing a build for my friend who doesn't really have a budget but has no idea what to get. To prevent him falling into the trap of a manufacturer ripping him off, I;m designing a build. But I want to know. Using this, can a GPU run off 0.25 of a PCIE lane?

There's no such thing as 0.25 of a lane.  You can only ever have 1 lane, that's the minimum.  Of course if you add PLX chips you can have more lanes provided than are actually fed through so I get what you mean about 0.25 lanes worth of bandwidth, and yes, that should be fine since mining doesn't really use bandwidth.

So what does this adapter do then? https://smile.amazon.co.uk/ROKOO-Expansion-Express-Switch-Multiplier/dp/B075DD6LX2/ref=sr_1_3?s=electronics&ie=UTF8&qid=1512408427&sr=1-3&keywords=pcie+x1+to+x16

Think he means 1/4 of a x16 lane. So x4 in this case.

It appears to give 4 x16 slots fed by a single 1x slot, so each would have 0.25 lane worth of bandwidth, but electrically, they're at least 1 lane each, if not more (I can't really tell by the picture)

to be direct (hopefully you will get what I'm saying)..  it will extend an 1x slot into 4x 16 slots.   Anything which needs high bandwidth should not be run on this.  Please do not confuse high GPU usage with high bandwidth.
