Power supply for PC
When you build a computer, or buy, it is important that the computer is working properly. A stable running PC starts with a good ATX power supply. This PSU (power supply unit) is 230 volts AC from the proper voltages that your computer needs, and that is at most 12 volts. You understand that such a piece - for most people unimportant - hardware has a lot to endure. Many computer problems are therefore by a malfunctioning power supply.
What does the computer power supply?
A feed is an important function namely: the conversion of AC (Alternating Current) to DC current (direct current). It is a variable AC power source, which must be converted to be used in a computer. The components in a computer using a similar flow: DC current.
There are different types of feeds available, active, passive and water-cooled power supplies.
If you rondsnufflet internet you see that much difference between the ability of the various power supplies. Starting at 300 watts and as high as 1000 watts. And the price is!
What to look when buying food?
The parts for the 12 volt rail to provide more amps are more expensive than the other voltages. Buy a cheap power supply bijvoorbeel 650 watts, then the 5V and 3.3V often with a fair amount of amps, unfortunately that is not the place where it comes, whether at the 12V connections, which the video card (s) and other stroomslurpers with power.
When you buy a proper diet, has at least 24 amps, but preferably 30 amps on 12 volt connections. May be desirable that the example 2, 12 volt connections with 1x 10 and 1x or 2x 15 amps 15 amps
The number indicates how many amps that supply at that voltage ballast (rail) can handle. The power to the power supply is indicated, the total sum of all the different amps to track, but can be converted to watts
Voltages
A fed 220 or 230 as input for what a large part to the motherboard. This only happens after it is converted from AC to DC. The hard drives, video card and optical drives get power directly from the power supply (12 volts)
The motherboard will have the following voltages:
* +3.3 Volt
* 5 Volt, usually for components
* 12 Volt, modern devices such as video cards that use a lot of power, but also for fans.
* -5 And -12 volts. This is rarely used. The -5 volt power supplies often come up in modern any more.
* 1.0 has a connector for ATX motherboard with 20 pins.
* ATX 2.0 is a connector with 24 pins. This is needed for an Intel LGA775 socket. Often feeds in addition to the connection of an additional 1.0 ATX 12-volt connection for the ATX 2.0 standard. This cable you prick alongside the cable into the motherboard.
Many modern power supplies have one or more S-ATA power connectors. There are also separate adapters to get from the standard 12-volt plugs a plug to s-ata.
Power works best around 50% of their maximum capacity. If you average power consumption of your system has, therefore do well to a power to procure one of the double handle. And the maximum power consumption of your system will set them cope with the efficiency it has, so pull in some extra margin is sometimes needed.
Of particular importance is the efficiency of the power supply. The best power supplies out over 90% efficiency, cheap generic copies, perhaps 70-75%. Power not converted is actually thrown away, and the difference between 10% and 30% of the current used disposal is great, especially if you have heavy systems. It is therefore of great importance to the nutrition info at the right to review or to the manufacturer's website in advance to find.
Faulty power supply? - Computer problems!
The 12 volt power to "all the basic components of a computer. When there is shortage amps on the +12 V in order to feed the various components, it can be challenging.
1. The computer is regularly
Usually this happens for example after installing a new video card or hard drive / optical drive. The power supply is overloaded .. Install a heavier diet will solve the problem.
2. You hear a loud bang and smoke coming from the diet
The food, the capacitors 12 volt power jumped. The damage is often limited to food.
3. You hear a bang and smoke coming from both power from the computer
The capacitors of the 12 volt power outlet in the food jumped, along with several components that were connected to it. Often the motherboard, processor, memory and video card is defective.
Grounding
Besides a good diet is a good socket with a precondition. From my own experience, excellent computer or hardly working at a poor or non-grounded outlet.
The computer can be on his ass get the PC fails, restart, for example, but there is nothing on the hard drives. That this is, is because of static electricity, normally through the earth into the wall is removed. Now that accumulates with many problems as a result. Several parts in this computer can malfunction.
Power connected but the computer does not do anything?
You have connected to the connector for the motherboard, but you may be the 12 volt socket on the motherboard password?
