power supply
Selection guide for assembling computer power supply (Power)
The importance of power supply
The Power Supply Unit (PSU) is responsible for converting external power into the stable voltage required by various components of the computer. A good power supply can ensure the stability of the computer system and avoid hardware damage caused by unstable voltage, so it is important to choose a suitable power supply.
Key points for choosing a power supply
1. Power requirements
Calculate the total power based on the needs of each computer component (such as CPU, GPU, hard drive, etc.). It is recommended to choose a power supply that is 20-30% higher than the required power to ensure stability and provide room for future upgrades. Generally, normal use requires about 400W - 600W, while high-performance gaming or graphics requires more than 650W.
2. 80 PLUS certification
80 PLUS is the certification standard for power efficiency, with certification levels including Standard, Bronze, Silver, Gold, Platinum and Titanium. The higher the grade, the higher the power conversion efficiency, which can reduce power consumption and heat. It is recommended to choose a gold medal or above power supply.
3. Modular design
Power supplies can be divided into full module, half module and non-module designs:
- Full module:All power cords are detachable for easy wire management and suitable for aesthetic needs.
- Half module:Some power cords are not detachable and the necessary wires are fixed, making it cost-effective.
- Non-mod:All power cords are non-detachable, which is suitable for those with a limited budget, but wire management is troublesome.
4. Security protection mechanism
Choose a power supply with basic protection mechanisms, including over-voltage protection (OVP), over-current protection (OCP), short-circuit protection (SCP), etc. These functions can protect the computer hardware when the voltage is abnormal and improve the safety of use.
5. Brand and warranty
Choosing well-known brands (such as Seasonic, Corsair, EVGA, etc.) can usually provide better product quality and after-sales service, as well as longer warranty times, providing a long-term and stable use experience.
Power calculation example
The following are recommended powers for different assembly requirements:
- General office or web browsing: 300W - 400W
- Mid-range gaming or multimedia applications: 500W - 650W
- High-performance gaming or workstation: 700W or more
in conclusion
Choosing the right power supply can ensure stable computer operation and reduce potential risks. It is recommended to select the appropriate power based on actual needs and consider 80 PLUS certification and safety protection features for optimal performance and durability.
