Miner Power Supply Unit
A Miner Power Supply Unit or PSU is used for supplying the electricity needed for the graphics cards of a digital currency extraction center. With this device, the power required for one or more graphics cards in a rig can be supplied. Since proper and fluctuating power supply increases the life of other equipment and the efficiency of miners, you have to be very careful in choosing the best PSU. In the electronic parts market, you can find different brands of PSUs. Almost all brands of PSUs have the same functionality with each other, but it is recommended that you look for products from well-known and reliable brands. .Poor quality of PSUs will cause breaking down of the other mining equipment.
PSU approvals and certifications
Quality control institutes classify PSU devices based on certain specifications. For this reason, when you look at the packaging or body of a PSU, you will see a symbol with the number 80 written on it. This logo actually shows how much power the PSU wastes in different pressures.
Unapproved PSU devices
Power supplies produced by unreliable brands usually have no endorsement by standard organizations. It does not matter if the voltage is 20% on the power supply or more. These PSU devices does not work efficiently.
Confirmation 80 Plus for PSU devices
The 80 Plus logo with a white background, means that the device is performing almost perfectly. No matter how much pressure is applied to the output of the PSU, the working efficiency of the device will not be less than 80%.
80 Plus Bronze Certificate PSU devices
PSU devices with 80 Plus bronze certification, perform better than white. In these PSU devices, you will reach the maximum efficiency only when the output power pressure does not exceed 50%. For this reason, its choice will not be very suitable for powerful miner devices.
80 Plus Silver Certificate PSU devices
If you use powerful and expensive mining devices, it is better not to think about PSU devices lower than silver certification. In silver-certified PSU devices the efficiency at normal pressure is about 88% and in the worst case it reaches 85%. For this reason, such PSUs can have a positive effect on power consumption control.
Gold Certificate PSU devices with stable performance
When it comes to supplying power for powerful graphic cards, you should look for an ideal PSU. Well-known brands such as Bitmain have introduced PSUs with more than 1000W power, which is approved by 80 Gold Plus. That is, their efficiency is 87% even at the highest working pressure, and with normal use, they provide 90% efficiency.
80 Plus Platinum Certificate PSU devices
In cases where a lot of equipment is installed on the rig, you should have 24-hour control over the status of the output power. 80 Plus Platinum certified PSU devices give you the assurance of working at 90% efficiency in all conditions.
80 Plus Titanium Certificate PSU devices
A titanium certified PSU can be a good option for professional digital currency miners cause its efficiency during normal working pressure is about 95%.
PSU Buying Tips
Several points should be considered together in buying the best PSU for a currency mining farm. If the PSU is not chosen suitably, the other valuable components such as graphics cards on the rig will easily damage .
Total power of PSU and adaptation to the mining system
Graphics cards used to mine digital currencies have a power consumption of about 150W. PSU devices for this purpose usually work with power above 600W to be able to supply power for several graphics cards. SO you have to choose the right power with graphics cards.
Output connectors of PSU
PSU connects to graphics cards with standard SATA or PCI-e connectors. For this reason, the type of cable should be compatible with the miner system. Otherwise, the installation of power becomes impossible and will be done with unprincipled tricks.
Cables
As you know, PSU can connect to multiple graphics cards. For this reason, cables are used to increase the length or number of outputs. Make sure that the cable is of good quality and has little effect on the output power.
Other points
The cooling fan and its sound is another important point to be considered, so that the PSU does not suffer from efficiency drop with increasing temperature. The authenticity of the product and the warranty are other points that you should not forget when buying.
