If we compare the image of a PC to a human, the CPU will no doubt be the “brainâ€, the electrical energy is blood, and the power source is the “heart and liver†of the PC. Convert 220V AC to DC, for each component. Provide precise and stable “blood.†Ensure that the PC is stable and efficient for us.
The "heart" that we are going to bask today is a 500W MASTERWATT LITE 500W full-mode power supply built by CoolerMaster.
CoolerMaster rated 500W MASTERWATT LITE 500W full-mode power supply (80Plus white card / Taiwan series capacitor / 85% efficiency / 3 year replacement) 299 yuan rated power 500W fan 12mm HDB hydraulic bearing fan PFC active efficiency 85% main Power Interface 20+4PinCPU 12V Power Supply Interface 4Pin+4Pin D 4pin Interface 3 SATA Interface 6 Input Voltage 150Vac-265Vac Support Wide Range Security Certification 3C Size 150 x 140 x 86mm Weight 1.62kg Support Temperature Control Peak Support 500W Jingdong Direct Link At present, only Jingdong sells, the price of 299 and the same series of MASTERWATT LITE 500W power supply (CoolerMaster) built before the same (CoolerMaster) to maintain the same price, even in the case of no reduction is added to the moment The popular and practical full module features, and maintain the same price, had to lament the cool wave this wave is very good.
CoolerMaster rated 500W MASTERWATT LITE 500W power supply (80Plus certified / Taiwan-based capacitor / 85% efficiency / three year replacement) 299 yuan MasterWatt Lite series uses all black matte spray, equipped with a HOB oil seal bearing fan, support PWM temperature control promises 100,000 hours of trouble-free life. The wire lengthening process is convenient for routing. 500W provides 2 6+2 pins to meet the needs of high-end graphics cards. Although this system is not high positioning, it adopts active PFC to support 150V to 265V wide voltage access, and it also has a complete protection mechanism, including overcurrent Jingdong direct link to encyclopedia map 
The outer packaging is a genuine green paperboard, black tone, simple and elegant, and very environmentally friendly. The author has always resisted the flashy packaging.
Although the pricing is only 299, but the warranty is not ambiguous, 3 years for new, rest assured use.
80Plus white card certification, non-virtual standard, green design, pure power, flat module wire, full module interface design and other related manufacturers information, revealing a sense of professionalism.
The back of the box has more detailed information, MasterWatt Lite 500 Fully Modular (WL500 full module) name is really long ah. . . I will also refer to the WL500 full module for short. Intel V2.31 standard, in line with ErP2013 energy saving and environmental protection regulations 5Vsb<0.5w. Active PFC (>0.9) supports normal operation under a wide range of 150V-265v, maximum current 4A @ 220v (that is to say the conversion rate of the power of the power of about 650W, it is recommended that you must never exceed the rated power when using the power Power is good). 120mm HDB Fan (dynamic hydraulic bearing fan), the efficiency of 85% has exceeded the standard of the white card. Multiple protection design with an average time to failure of >100,000 hours. The parameters feel very comfortable.
Certificate of conformity, manufactured by Taiwanese factory.
Accessories are still relatively simple, the interface provided is still very rich in PCI-E6+2 interface*2, 4Pin peripheral interface*3, SATA interface*6, but also provides a 4pin floppy drive interface for the first time, which made me feel very surprised. It is very heart.
Ontology appearance, handsome branding.
Last name. The boss gave me 10 pounds 500w power, yes, to WL500 full module.
The interface of the back work is flat and the whole shell is painted with black matte. The handsome feel is also very good and it is on the grade. The foundry of the WL500 full module is Yiheng. The quality of Yiheng is believed to be very much appreciated by most people.
Equipped with a HDB Fan (dynamic hydraulic bearing fan), PWM control, high efficiency and quiet.
Through the protective net, we can see the double EMI filter that is closest to us, as well as active PFC components, equipped with switches.
The detailed parameters on the back are not repeated in detail.
Fragile stickers, if you have to remove the power supply, this fragile sticker is definitely not safe. This way you will also lose the warranty. Non-professionals are still advised not to open, and it is still a bit dangerous to pass the power supply.
On "chicken"
Tucao back line can be washed and slept. . I am lazy, as long as I can't see the place, I don't usually feel very much. .
Installation of snakeskin nets was completed.
A light broiler test was done. The original heat sink was overclocked to 3.8 on the Ryzen R7 1700. In the roasted chicken state, the CPU temperature was 60 degrees and the heat sink temperature was 43 degrees. At this time, the CPU fan noise is close to 50 dB and the speed is 80%
Power outlet temperature is only 18 degrees, 35 dB noise, PS indoor temperature is about 12 degrees, temperature and noise control is still quite good.
MasterWatt Lite 500 Fully Modular (WL500 full module) can actually be regarded as a non-upgrade upgrade of CoolerMaster 500W MASTERWATT LITE (non-full-module version), plus the quality of Coolermaster and Yiheng's foundry does not need to spend a penny to experience the simplicity and equivalency of the modular power supply. Why not do it?
CoolerMaster rated 500W MASTERWATT LITE 500W full-mode power supply (80Plus white card / Taiwan capacitance / 85% efficiency / 3 year replacement) 299 yuan Jingdong direct link Semiconductor Fuse And Ferrite
Fuse refers to an electric appliance that, when the current exceeds the specified value, melts the fuse and disconnects the circuit with the heat generated by itself.When the current exceeds the specified value for a period of time, the fuse melts and disconnects the circuit with the heat generated by the fuse itself.A current protector made from this principle.The fuse is widely used in high and low voltage power distribution system and control system as well as power equipment.
Ferrite is a metal oxide with ferrous magnetism.As far as electrical properties are concerned, the resistivity of ferrite is much larger than that of single metal or alloy magnetic materials, and it has higher dielectric properties.Ferrite magnetic energy also shows high permeability at high frequencies.As a result, ferrite has become a non-metallic magnetic material widely used in the field of high frequency and weak current.Due to the low ferrite magnetic energy stored in the unit volume, saturated magnetic induction strength (Bs) and low (usually only pure iron 1/3 ~ 1/5), and thus limits its higher requirements in the low-frequency magnetic energy density in the field of high voltage and high power applications.
