PC Power Supply – Diagnostics and Replacement | Bahía Blanca

PC power supply diagnostics

We perform comprehensive power supply testing to detect voltage faults, instability, ripple, intermittent cutoffs, or out-of-range lines that affect the power-on and stability of the equipment.

We use professional measuring tools (load tester, multimeter, oscilloscope) to check each power line and ensure that the PC operates stably and safely.
