ATX Power supply form factor

ATX Power supply form factor
ATX stands for "Advanced Technology Extended". This is the standardization of the latest computer packages. All computer components, which are also standardized to ATX can be installed in this housing. ATX power supplies support the latest additional features that bring any modern computer with it. The different types of PC power supplies differ mainly due to equipment size and the number of available slots and ports. To meet the ATX standard power supply, it should at least provide a

AT Power Supply Form Factor

AT Power Supply Form Factor
AT means "Advanced Technology" and is the predecessor of today's standard ATX format. Previously, IBM developed the XT format. The AT-format is a standardized form factor, which determines how large the main board, how wide must be the spacing between holes and where all components are placed. In addition to the AT format, there is a smaller version, the Baby AT format, which was developed somewhat later. (more…)

PC power supply : Cool without a fan

PC power supply : Cool without a fan
Now there are  great PC power supplies that operate without a fan. As a result, these devices operate completely silently. The heat produced is dissipated in the computer by using passive cooling processes. The temperatures are derived through a copper wire from the housing interior to the exterior. There are an aluminum heat sink that can cool the temperature. This type of system ensures that the heat is released into the environment. The interior of the housing isn't heated

Removing the Desktop PC Power Supply

Removing the Desktop PC Power Supply
Before removing a PC power supply, make sure that the computer has been removed from power. In order if it is carrying a residual voltage in the power supply, you must push the power button-on. However, be careful, because the PC power supply unit can store up to 5 minutes after it's cut off from electricity.  Don't damage the sensitive components, for example by touching it, one must be grounded on a heating pipe. In order to supply the

Build A PC Power Supply

Build A PC Power Supply
Built a PC power supply basically quite simple. It consists of a housing made of metal. A Euro unit connector is for connecting to the socket, and there is a power switch. The PC power supply has at least one fan. There are power supply that work with multiple fans. (more…)

PC Power Supply Basic

PC Power Supply Basic
The function of your personal computer power supply is very simple: It distributes the required electrical power from the electric outlet to all computer devices. Power supply is responsible for transforming Alternating Current (AC) from a wall outlet into Direct Current (DC), because only in this way, computer hardware can work. Since each component requires a certain voltage, it will be distributed to 12 volt, 5volt and 3.3volt. Processors and graphics cards are the most widely used source of 12

12 VDC TO 117 VAC / 60HZ POWER INVERTER

12 VDC TO 117 VAC / 60HZ POWER INVERTER
Capacitor C5 and potentiometer R12 figure out the frequency of the output signal at pin number 3 of IC1, the 555oscillator. The output signal is differentiated by C3 and C4 before it's input to the base of power transistors Q1 and Q2 through diodes D1 and D2, respectively. The signal from IC1 is adjusted to 120 Hertz, because the flip-flop created by transistors Q3 and Q4 splits the frequency by two. (more…)

12 Volt Battery charger

12 Volt Battery charger
The following schematic is a high-performance battery charger for gelled electrolyte lead acid battery. Battery charger quickly recharges lead acid battery  and shuts off at a full charge. Innitially, charging current has limitations to 2 Ampere. While the battery voltage goes up, current to the lead acid battery  decrease, and if the current has decrease to 150 mA, the battery charger changes to a lower float voltage protecting against overcharge.
