Computer Power Supply “Breakdown Failure” Scheme

Project Overview ： Computer power supply

        The computer power supply provides power to all components within the system, naturally serving as the foundation for the machine’s overall stability. In recent years, the dramatic increase in power consumption of hardware—such as CPUs and graphics cards—has further expanded the demand for high‑wattage, high‑quality power supplies. 。

        This is a product of a certain export brand. PC Power supply customer. They raised the issues they urgently needed to address, and Jiaxun selected solutions that were well-suited to their needs.

Project Issue: MUR2020CT Breakdown failure

The customer’s products are sold in many countries. In the Middle East or in certain countries in Africa, summer temperatures can reach 45 above ℃, which necessitates a highly stringent thermal management design for the entire chassis, particularly in component selection; previously, Customers will Often receive MUR2020CT Resolve customer complaints.

Solution: Recommended Model MUR2020CT

        After a thorough investigation, we determined that the frequent breakdowns of the components previously selected by the customer were due to an improper chip‑to‑application match on the supplier’s end, which made the devices prone to breakdown under high current conditions. Jiaxun promptly provided a tailored solution and recommended Jiaxun Electronics. Fast-recovery diode under the brand MUR2020CT , this model MUR2020CT With a relatively low forward voltage drop (VF) and no significant increase in reverse current (IR), the device can handle high currents without a noticeable temperature rise. In our lab tests, under full‑load conditions at 20 A, the output voltage remained stable at approximately 11.30–11.40 V, while the junction temperature stayed below 105°C, fully meeting the customer’s requirements.

Customer Satisfaction: ★ ★ ★ ★ ★

        The customer has chosen to partner with Jiaxun Electronics. We are pleased that they have acknowledged our objective provision of relevant data, including the MUR2020CT—such as chip‑area specifications and experimental results—and recognize Jiaxun’s dedicated efforts. We extend our gratitude for this recognition and remain committed to delivering tailored solutions and the most suitable products, ensuring customer satisfaction, which is Jiaxun’s core mission.
