Professional diagnostic and board-level repair service for this I-Star Computer Co. TC-400R2UP power supply.

I‑Star Computer Co. TC‑400R2UP is a 400 W, 2U redundant switching power supply designed for industrial servers and telecom equipment. Known failure modes include degraded electrolytic capacitors on the input filter or output stage, fan motor burnout leading to overheating, and failure of the active PFC control IC which can trigger over‑power shutdowns. First‑check diagnostics: verify AC inlet voltage and continuity through the power module; test the 12 V/5 V/3.3 V outputs with a multimeter for correct voltage levels and load regulation; inspect the internal fan and thermal sensors for proper operation, then review any protection trip logs or LED status indicators for over‑power, over‑voltage, or short‑circuit conditions.
