The OEM for the SuperNova 1500 was Etasis, and while they have a good rep in server PSUs, they have a mixed rep in consumer versions. And, the 1500 was loud, performed acceptably but not great, and had that gimmicky switch where you could make it act like it had multiple rails or a single rail. That is just silly in a modern PSU design, and one more thing to go wrong.
If this is actually made by Super Flower, and w/o the gimmick switch, I'd say it is could be a very nice PSU to consider - assuming it gets good reviews by people who test these things right. I never buy a PSU by brand or OEM alone. If it's another Etasis unit - meh. Those reviews would have to be seriously glowing for me to consider one.
