Compatibility check 1: clamp or cutout fit
For desktop power centers, record the exact value, standard, measurement, or supported condition behind clamp or cutout fit before checkout. A broad category label does not prove that the selected variant fits. Confirm the manufacturer, complete model, hardware revision, operating-system support, port layout, dimensions, power supply, and included cables rather than assuming similarly named products share limits.
Compatibility check 2: total AC rating and surge protection
Test total AC rating and surge protection across the actual desk, body position, computer, operating system, cable reach, workday, and shared-device routine—not a product-photo setup. If this desktop power centers fit depends on a driver, dock, cable, adapter, mount, power supply, operating-system feature, desk clearance, or assembly service, confirm the exact part, service, or behavior as part of compatibility.
Compatibility checks 3 and 4: USB-C power-delivery allocation; cord length, grounding, and spacing from liquids
For desktop power centers, USB-C power-delivery allocation and cord length, grounding, and spacing from liquids are the limiting conditions most likely to surface only after installation. Measure the smallest clearance, weakest connection, least compatible user or device, and the most demanding normal task. Passing an ideal bench test is not enough.
Prove fit in a reversible order
Use this sequence: measure the edge, mount without crushing the surface, route the mains cord safely, connect known loads, and verify shared USB power behavior. Keep labels, packaging, manuals, and the previous system until the product works through normal use and a recovery test. Photograph wiring, measurements, or assembly states that would be difficult to reconstruct.
A failed fit check is a stop signal
Stop when the desk edge is incompatible, liquids are likely, high-draw equipment exceeds rating, or an under-desk certified power strip is safer. Do not repair a fundamental mismatch with unapproved accessories, copied settings, or community anecdotes. Use under-desk surge protectors when it meets the job with a clearer compatibility path.
