keyboard problem , its clicking random keys

Make sure you use the provided cable, or if you want to use a 3rd party cable reduce LED brightness.
What you're experiencing is due to voltage drop coming from the power source.
If you're using the yellow and black braided Wooting cable your second hand purchase should have come with, then might also want to change USB ports to one directly connected to the motherboard

so i did use new cable that arrived from amazon hours ago not worked also tried close brightness 0 light not worked , the problem is when u put low actuation [under 1mm example 0.1mm] point it start go crazy tipping random if i put higher all good .. eh :/ sad.. i wanted have this keyboard as low as possible actuation point if it not work than is pointless i just go back to my apex pro tlk .. sadly [ the cable i had from guy i bought keyboard was the original one but has some problemas the one i got from amazon today] strangly keyboard doesnt give any problems when activation point is on 1mm when i go lower its strat go crazy u still think its due to ,, voltage ? ,, otherwise i just send back to this guy who sold me ebay seems like try sell me some broken keyboard probably..

Is there anything magnetic near the keyboard?

[orchid spoke]

Adding on to this; would using a powered usb hub (as in plugged into an outlet) fix the voltage issue?

[sturdy vessel]

In some cases yes, but that is highly dependent on the usb hub itself.

[sleek knot]

Yes - But no.

The voltage drop happens through the cable. So if the cable isn't stable enough for a Keyboard to PC connection, connecting it to a USB hub will be the same problem (except now you have an additional point of failure to deal with)
