It does appear to have PCIe connectors, from the eBay image. 2x6pin?
While it might be capable enough, I'd be skeptical.
From what you've posted from the labelling, there's dual 16A 12V rails.
16x 12 = 192W x 2 = 384W theoretically.
Dual rails never scale 100%, so it's probably more like 25A / 300W max.
While that could probably run a 4460 + 1060 system, I wouldn't risk it.
