Got it. It's a monstrosity with 3 external power supplies that I have to wire in myself... however even the power side needs to be screwed in with bare wires, and that's basically illegal to do in my country unless you're a certified A grade electrician... so I'm not sure exactly what to do with it yet

External power supplies?? Got a picture?
It's as per the opening post, but with one extra power supply (presumably a spare/redundancy). Here's some photos, including a baseball cap for size comparison:

STI.
1)extra power supply can give you the ability to over clock. The boards are equipped with 32+A current capacity power supply per chip:), in 25G/s mode, it only consume 20A per chip. so it has room to do the over clock.
2)Linear Tech power supply + careful design gives the ripple only at 20mv:), it will stabilize chips using the higher clock without too much HW error.
