Would a single EVGA Supernova 1600 G2 have enough connectors for six Vega 56's (with 8+6 PCIe connectors), as well as the 3 sata and 3 molex connectors on the Onda D1800? I'm struggling to understand the specs of the PSU. And buying additional splitters and cables gets quite annoying when those brands prevent you from using third party cables...
vega 56 has 8+8, at least my MSI 56 does, however, you can always connect a cheap 6 to 8 extender to the second branch of the 8+6 cable.
At least, i did just that and it works fine, no cable overheating.
I have 7 old rigs with R9-390s with EVGA-1600-G2 circa 2015, and the bloody thing is still running - incredible.
These old rigs are going to be upgraded with D1800s.
The 1600-G2 has 9 ports for VGA, and 3 sata and 3 molex to support D1800 no issues.
2 x Perif (2 x molex cables) -- double and triple molex on single cable
4 x SATA (4 x Sata cables) -- double and triple sata on single cable
Perif and sata cables compatible with any of these 4+2 ports.
I have one big box of extra cables from a total of 42 x EVGAs since 2015, EVGA-1000w, 1300w, 1600w, from the 1st farm.
The 2nd farm, is mainly server PSU consisting of HP1200w, 1000w, 750w and 2400w Deltas.
