PSUs contain high-voltage components; "patching" or opening them should only be done by trained technicians.
Compact and semi-modular, often used in space-constrained rack systems like the H3C switch series . hys3c210cs power supply patched

Stock: ~82% at full load. Patched: ~85% at full load (due to lower ESR losses in capacitors). The difference is marginal but measurable. hys3c210cs power supply patched
