On the power supply shelf those blue blocks can put out 20 amps at 23 volts EACH they weigh 40 pounds each. The pretty meters are a, as of yet unfinished, adjustable 10 amp RMS supply with 50,000 uf doing the filtering, it weighs another 15 pounds. So the total weight on the shelf is only 120 pounds or so, its smiling not sagging i promise! The shelf above my desk is actually a tv stand and the desk, while small, was free.
