That Enermax only has 2 PCI-E connectors according to the cables tab on the website. Jupiter requires 4. I'm not sure which PSUs supply 4 PCI-E connectors, unless we'd have to use adapters.
Each cable looks like this. There are four of them. The linked supply has 8 PCIe connectors total.
8 PCIe connectors is actually optimal because while Jupiter only needs 4 connectors and the connector can handle 300W+ there is no easy way to know if a PSU with only 4 connector is designed to deliver that much current on the wire safely. By the spec a PSU only needs to deliver 75W to each 6pin connector and 150W to each 8pin connector and be compliant. Most PSU with only 4 connectors are probably fine but there is no good way other than testing to know for sure. The nice thing about a PSU like this (or any PSU with 8 connectors on 4 sets of cables) is you know that it can safely deliver 300W (150W + 150W) on each set of wires.
