Please refrain from using Molex to EPS 12v adapters on your 4p systems.
I have seen this picture and those like it too much...
Even dual molex to 12v eps are not a good idea.
If there is absolutely no way to do an 8pin EPS from the psu directly (no Ys or splitters)...
I suggest a PCIE to EPS adapter.
Each wire is rated at about 7A, the EPS 8pin is therefore rated at 28A.
A single molex has 1 7A line... dual molex 2, pcie 3....
Trying to push 28A through a single wire is just a bad idea.
Also 4-pin Molex are typically on the same "rail" as the 24pin...so you are not really gaining anything other than a firehazard.
