As long as you have a little in-depth understanding of the DIY field, you will find that even those players who buy second-hand hardware to build a cost-effective platform for fun, that is, what everyone often calls "garbage guys", do not dare to be sloppy in the choice of power supply, other hardware can be saved, and the power supply must also choose a reliable big brand of first-hand goods.
Because other hardware will cause some performance bottlenecks at most, and the quality of the power supply is directly related to the stability and reliability of the entire platform, "ripple instability and explosion" is not a joke. I myself was pit by inferior power supplies a few years ago, and even after the power supply "exploded" once, it also affected the constitution of the CPU, and then even if you change the good power supply, you can't achieve the original overclocking rate, pulling to the original frequency has a 99% chance of blue screen, and 1% is a blue screen within five minutes after entering the system.
PC power supply: Hangjia Gold Medal 850W MVP K850X power supply
In terms of appearance alone, the current PC power supply can be divided into three types: full module, half module and non-module. Among them, the non-module means that all the cables are non-pluggable, while the semi-module is to retain a part of the cable, such as the power supply line of the CPU, motherboard and graphics card, and the remaining cable is pluggable design. I don't recommend these two designs very much, because they are a nightmare for chassis cable management, and there will be many inconveniences when installing the machine.
In contrast, hangjia MVP K850X this full module power supply is much more humanized, how many power supply lines you want can be directly plugged in, cable management is very convenient. Especially in the installation process, you can choose to connect the POWER supply line of the CPU and the motherboard first, and then plug the other end into the power supply after installing it into the chassis, instead of installing the entire motherboard, and then face the risk of being cut by the radiator for half a day just to connect.
And the full module power supply also has a great advantage in terms of appearance, because this Hangjia power supply adopts a standardized design, so in addition to the wire that comes with it, you can also buy DIY cables of different colors by yourself. I just bought a power supply cable with RGB lighting effects to make the whole chassis cooler.
And we often hear of white, bronze, gold power, represents the conversion rate of the power supply, such as the need to input 100W of power to supply the entire platform 87W of electricity, then the conversion rate is 87%, can reach the standard of gold. These represent not only the efficiency of the power supply, the higher conversion rate also means that the internal materials of the entire power supply are more solid, so it is not that their computer power consumption is not high, you can choose a white card at will, the impact of the power supply is almost all aspects, and the stability is more important.
This Hangjia power supply uses the LLC + synchronous rectification + DC-DC scheme, such a configuration is a high-end version in the power supply, so its conversion efficiency has also reached the gold certification of 80 Plus. At 50% of the load, its conversion efficiency can even reach 90.9%, and the conversion rate of 88.13% can be guaranteed under full load, which is higher than the gold medal standard overall, which is a very good level.
In addition, many power supplies are not converted high enough in a low-power state, and the wasted electrical energy will be transferred out in the form of heat, which leads to the continuous operation of the fan under low load, resulting in greater noise. This Hangjia power supply is very high due to its own conversion efficiency, so there will be no excessive heat at all when the load below 300W, at this time the fan is completely non-rotating, which can ensure the quietness of daily use. When the overall load reaches more than 300W, it will turn on the intelligent temperature control mode to ensure sufficient stable operation.
Everyone knows that the domestic civil power supply standard is 220V voltage, but in fact, due to the complexity of the entire mains system, this value is not constant, and sometimes there will even be large fluctuations, and the poor power supply will appear various unstable situations at this time. Another important reason why I chose this Hangjia power supply is its full-frame design, which can guarantee normal operation between 90V and 264V, and the mains voltage fluctuation is not panicked.
Wireless charging pad: Hangjia SSA109
After suffering a loss before, I not only replaced the power supply of the computer, but also replaced the other power supply equipment with Hangjia products, such as this Hangjia SSA109 wireless charger. It's a wireless charging device with Qi certification, so it's quite broad in terms of compatibility, from phones to headphones, and even my razor can be charged with it, basically as long as it supports wireless charging devices can be compatible.
And it is not like the ordinary wireless charger like the wireless charger only wireless charging one function, it is also equipped with 2 USB sockets, these two sockets are all able to charge. In other words, as long as I have this one device, I can charge three machines at the same time, and I don't need to make the table full of chargers like before, which is perfect for people like me who like simple desktops. 【Click to buy】
Insert: Hangjia SST307
Of course, as one of the power supply bases, the plug is also not to be ignored, because of the need to withstand the total power of multiple devices at the same time, the safety of the plug has become particularly important. The Hangjia SST307 insert I am using now is a plug that uses high flame retardant PC material and has passed CCC safety certification, and has passed a very strict multi-environment test, which can be said to be very excellent in safety.
Although I already have the Hangjia SSA109, which can basically meet the charging of my commonly used equipment, who will think that there are too many charging ports? This plug excludes three conventional holes with four USB interfaces that support buck compensation technology, and the average user can use it to meet most of the charging needs even if there is no charging head, and can also save desktop space. 【Click to buy】
This program is the final choice after I have done a lot of homework and compared many similar products, and it took a long time to recommend it to everyone. If you encounter someone who does not know how to choose when you start such products, it is not wrong to buy the above products directly.
