i'm asking cause i've seen this on retail psu units. i have not personally done it due to fear and have only used it if the cables already come stock in that fashion. for example, some psu comes with cables like this (cable A): and some are just single like this (cable B): so my question is if i could take cable B and put a y-splitter on the end and use it for a gpu that requires two 8pin pcie connectors like a evga 1080ti ftw3: my 2nd questions, i assume it would be safe to use cable A for the card above, right? so the question remains, should you get a "quality" y splitter and split a single 8pin into two 8pin or just hunt for a power supply that has enough connectors to meet the needs of your gpus? it can get crazy if you are building an 8-gpu rig and each gpu requires two 8pin connectors meaning you need sixteen 8pin connectors, yikes! thoughts? or am i way out in left field? i have not personally used splitters yet so i continue to hunt for enough stock 8pin connectors or add another psu. as a given: assume only quality psu will be used (as i don't go cheap when it comes to psu but the $ can add up fast).
