Using Y-spliiter for rx Vega is very dangerous. It can't handle the power spikes fluctuations, however you can use dual cerfified cable like the one EVGA has with 1 end 6+2 pin and the other end with 6pin and use a 6 to 8 pin adaptor

Dual I understand. Certified, I do not. The whole world of cabling is new to me, however. Is there a trusted certification authority or something? Also, I haven't been able to find any 8-pin to 2x8-pin that seem to be from reputable vendors. Everyone seems to make 6-pin ones, but the 8-pin ones seem harder to find. Am I missing something or are larger vendors doing this intentionally?

Per my little research..
Credit to stackexchange question.. "Is there any limit on how many SATA power connectors i can extend" (superuser).
Helpful link was wire gauge to current rating.. Seems 18 gauge for short runs can max out at 16A, 16 gauge at 22A, which translates to roughly 12*16 and (or) 12*22.
As per their nifty chart, they're saying (as conservative figures) for max load for the different wires:

Gauge	Max Load
18	192
16	264

I could definitely be wrong. So eat with salt. But since everyone's undervolting, if they're using the 18 gauge, they're probably somewhere near the top end of the allowable range. If the cards or software fault, however, and they start pulling 250+ from the psu (does anyone know what it pulls w/o the undervolt--has anyone measured the wire?), I guess it's anyone's chance if a fire starts/they begin to melt? For posterity and the curious, I've got vega64 lc's running on these cords.
If anyone's got wiring like this, but is NOT undervolting, I would be curious as to how long they've been running, how many watts they've been pulling, etc. It's hard to find solid information out there.
