I wound up going another direction and the ebay seller I bought this from does not accept returns so looking to unload this.
Item description: Butterfly Labs BFL 850W 80+ Gold ATX Fully Modular Power Supply New Sealed Box
[Note]: though the printed info on the box says it includes 3 each of sata and molex cables, it seems these actually come with only one of each. Additional ones can be sourced on Ebay however using Great Wall and/or OCZ as your search term stepping off point.
Asking: $40 (plus shipping)
Feel free to message here or on Discord with your zip code if you want a shipping quote.
Thanks for looking.
