hello. First post here at ocuk have been using this forum for a wealth of knowledge for years hopefully someone can help me with my somewhat complicated question. Might need someone with some serious cable mod experience.

I have recently bought a VEga 64 liquid cooled edition, a powerhungry beast at the best of times. Currently it is running off of the dual 8pin gpu cable that came with the psu, however these are doubled and they are not separate wires for each pcie connector. While this runs I feel if I overclocked it too hard (modifying the power table) it will draw too much for the single wire(and it may heat up).

I currently have a superflower leadex 2 850w gold psu. The connectors psu side are ‘universal’ 3x3 connectors. My question is this:

I have 2 spare 3x3 off psu not being used, both Molex and satapower. If I wired 2 x8 pin pcie wires using high quality wire and sheathing and matching the pinout of the current dual 8pin wire, will this overload/damage my psu’ 12v rail? Am I alright to make 2 shortened custom pcie cables for this power supply or can I only use 1 pcie power cable at one time from a psu of this strength, I don’t see power draw being much higher I just want to run 2 cables for it!
 
Right so I have misplaced a lead. Damn thank you very much. I may be able to find it but I was just looking for confirmation that I was Okay to make a custom pair anyway. I will be using the original connectors, however some less knowledgeable people earlier today told me I would 'Blow it all up' and I like to err on the side of caution.
Have 17awg(cablemod) and connectors on the way also, and have undervolted the card to a point im very happy with, hoever my thermals are way below where they need to be and I can still hit the powerlimit relatively easily, and don't mind burning another 75 watts for like 3% performance, so was going to modify the powertable.
