Advice 1: How to increase usb power

Initially, a predetermined power and voltage in the USB ports cannot be changed, however there is a possibility of replacement of some components of the computer to optimize the work with data ports.
How to increase usb power
You will need
  • - information about your computer configuration;
  • - additional power supply unit.
Instruction
1
Find out your motherboard model and read its review online. Please note that the increase in voltage that is distributed to the USB ports on the computer is only possible in the latest models of motherboards and only if in the BIOS the setting is set below the maximum.
2
Never increase voltage USB with custom tools or overclocking you'll just mess up the South bridge of the motherboard, or, even worse, the power supply or the whole computer.
3
Open the settings of the BIOS and review the settings of the voltage distribution on the USB ports. If this is an option, increase this parameter to the maximum possible, and exit, saving your changes. If your motherboard does not support this function, you can replace it with a newer model, depending on how you need it.
4
To increase the power supplied to USB ports, you can use the special Autonomous power supply 5V, which are sold in computer stores in your city. For each USB port in your computer is allocated a certain number of capacity units (500 mA) and modify the figure as impossible as to raise the voltage above USB possible - you'll just mess up the chip of the motherboard.
5
Use special adapters to connect USB devices, it helps you to preserve the proper status of ports on your computer. However, note that the ports work in full power data adapter and the cables must be of appropriate quality, as the various Chinese bands and non-original cables for connecting portable devices ruining the ports and reduce the speed of data exchange.
Useful advice
Use original cables to connect devices.

Advice 2 : How to increase the capacity of the power supply

In the process of using a home computer you may find that the original capacity of unit power is not enough. Do not hurry to part with it and buy a new one, because power can be increased.
How to increase the capacity of the power supply
You will need
  • — power supply unit;
  • capacitors;
  • — chokes;
  • — three assemblies;
  • diode;
  • — soldering iron.
Instruction
1
Open the power supply and estimate its technical characteristics. To do this, it is enough to gently remove the metal housing. You need to know that self-revision at home may be subjected exclusively to that unit, the transformer which has dimensions of not less than 3 x 3 x 3 cm
2
Replace the high-voltage large capacitors. It is recommended to install in the power supply those that have a capacity of at least 470мкф x 200V. In the low-voltage part supply chokes, which can be obtained in several ways. For example, try yourself on a ferrite ring to wrap the wire with lacquer insulation. Or remove the chokes with the old, the used and unnecessary power supplies.
3
Now respeite smoothing capacitors in the voids that are in the low-voltage side of the power supply to fill them. To increase the power to make three capacitors. They must meet certain parameters, namely to have the capacity 2200мкф x 16V.
4
Replace diode Assembly. To do this, desolder the conclusions of the Assembly and carefully pull it out of the plastic holder, taking care not to prevent attacks on the rectifier unit. Next, clean the installation area is free from residue of epoxy resin. Install a new two or three assemblies, for example MOSPEC S30D40 or similar type, they can be purchased in a specialty store. Glue the body diode Assembly to the holder with epoxy resin.
5
Reduce the voltage of the second, dvenadtsatiperstnoi channel in the power supply. To do this, solder high speed silicon switching diode. Be sure to turn off power at 0.6 V, if this is not done, the computer will be under harmful excessive voltage. If you complete all the steps correctly, updated the computer will work faster and better, and will last another few years.
