How about a back view to show off our new PSUs! We've had them for a while, but just got upgraded fans so we could run them @100%.

Each shelf (or pair of rigs) has one, as well as 2 more of them powering our 7 Antminers (not pictured).

The other PSUs on the other shelves are running 8 GPUs, but on the top shelf we're only having it run 7, cuz the 290s draw a little more power than the 280x.

Those are 3x 60mm delta fans strapped to the side of the PSU. That PSU prolly has more airflow now than it ever has.
