PC power supplies have built-in surge protection or not ? TECHWIN provides indispensable protection

PC power supplies (PSUs) typically include basic surge protection, but they are not designed to handle large power surges (e.g., lightning strikes or grid fluctuations) effectively. Here’s how Shenzhen Techwin Lightning Technologies (TECHWIN) can enhance PC power supply protection with its surge protective devices (SPDs) and expertise in lightning protection:

1. Limitations of Built-in Surge Protection in PC PSUs

Basic Protection: Most PSUs include minimal surge suppression (MOVs, filtering) for small voltage spikes but lack robust defense against high-energy surges.

No Dedicated SPDs: PSUs prioritize stable power delivery over surge protection, leaving PCs vulnerable to electrical surges.

Short Lifespan: Built-in components degrade over time, silently failing without warning.

2. How TECHWIN Can Enhance PC Power Supply Protection

a) External Surge Protectors for PCs

TECHWIN’s Lightning Protection PDU (e.g., PDU10-220-6) can be installed between the wall outlet and the PC:

Advantages:

- Higher surge tolerance (absorbs more surge energy than PSUs).

- Faster response time (nanoseconds vs. milliseconds in PSUs) and low residual pressure .

- Extends the lifespan of PC components by diverting surges before they reach the PSU.

b) Type 2/Class C protection DIN-rail AC surge protector

TECHWIN’s SPDs modular (e.g., M40B2) with high energy MOV technology, installed into power distribution box before the wall outlet，can quickly response to protect the PCs.

c) Custom SPDs for Industrial/Data Center PCs

For overall protection of general power distribution in high-risk environments (such as computer rooms, data centers), TECHWIN featured T1+T2 SPD (eg., MA25/4) can act as 3-phase SPDs for server racks.

d) Compliance & Safety Standards

TECHWIN’s SPDs comply with IEC 61643 and UL 1449, ensuring compatibility with global PC power systems.

Conclusion

While PC power supplies offer minimal surge protection, TECHWIN’s SPDs provide professional-grade defense against high-energy surges. By offering Lightning Protection PDU, T2/Class C protection modules, and industrial solutions, TECHWIN can significantly improve PC power safety—especially in lightning-prone or unstable grid regions.
