Pricing and availability is unknown but considering the previous NightJar 500W PSU retailed for $199 we expect this unit to be quite pricey.
Cabling includes a 24-pin ATX, 4+4-pin EPS, two 6+2-pin PCIe, six SATA, five Molex, and one Berg. On offer are flat (ribbon) cables that are easier to bend around tight corners in your case.
