Be careful though on the power intensive algos. You will draw more current from one connector. If you use your PSU cable without splitter, that should be fine on low power algos. But if you e.g. mine X11 and, even worse, connect one splitter from a 6pin PSU cable to two boards, this wont be a good idea.
And just remember again: Ratinds: 8pin connector 150w, 6pin connector 75w.
[edit]
the 75/100 watt concept only used for gpu because it's utilize the sense pin, i don't think miner use that.
