I recently got a 1000 G2 PSU, and have a quick question about the best way to connect two 980ti's to the PSU:
 
I have two options:
 
A;  the PSU comes with two number PCIe 6+2 pin +6 pin cables, so I can run one of these to each GPU:
 

 
 
or:
 
B; The PSU comes with  four number PCIe 6+2 pin cables, so I can run two of these to each GPU:
 

 
 
To me option B looks better; but is it safe-is it loading the rail(s) of the PSU correctly? 
 
Thanks in advance.

    for best results, use a separate cable for each connection

    Either is fine ,.. I just prefer pic  A .  That is how I run mine because it is less cabling-looks cleaner, easier
     
    I just use pic A   cables off seperate rails on the psu to each separate video card

    Thanks for the prompt replies guys, I will go with B, as I can easily hide any slack behind the motherboard tray and I plan on overclocking the GPU's, so no harm having the extra cable cores.

    until 225W of power (per card) and litle to no OC there is no problem with using the first option.
    going above that you should definitely use the second one.

    I went with option B; the PSU is excellent, well finished and quiet...much quieter than my previous corsair one-and no damn coil whine at idle. Result 
     
    The stock cables are good quality, but thinking the white sleeved EVGA kit will be the next upgrade. My previous build I sleeved my own with MDPC sleeving, but they've dropped off the planet lately.
