A mistake in Page 4: At 200W to 400W output, the 12V line was down 0.1~0.15V. At full load, it was -0.25V, nearly 5% down. 0.25V load regulation on +12V translates to ~2% instead of ~5%, so ST50NF's +12V output is actually (a touch) more stable than STR500. Both power supplies use technologies that ...
