Yes, it will fit. It's a poor quality power supply, but it's definitely compatible.
I would recommend choosing a different unit. The CX units are tier 4, which is not very good and they have a rather high early failure rate. I'd recommend something that's tier 1 or 2 from the following list based on the recommended capacity of your GPU card model which I've linked as well.

Not really. The B1 series units are not among those built for EVGA by Super Flower, and are inferior to those units. This would be a very good choice though.
