In the last couple of years, the PC market has changed from being almost 100% performance focussed, to becoming very noise conscious. While delta fans running at 7000rpms were accepted a few years ago, even fans running at 3000rpms are considered noisy today. This combined with the rapidly rising power requirements from today’s high-end components, the performance, cooling and noise of power sup

by: Steven Stoddard Power Supply If you suspect your power supply is giving you trouble, make sure you check it out fast, because power supplies can make trouble with the rest of your system as well. Irregular voltages sent from the power supply can short circuit and overheat your components thus frying them and making them unusable. Some faulty power supplies have even caught on fire, but if you’re lucky it might just smoke a little and start to smell. A few signals that your power supply is bad or is going bad would be erratic and seemingly random system behavior like system hangs and crashes, and burning smells along with smoke.

How The Efficiency Rating of A Power Supply Can Save You Money
Introduction
Personal computers use a tremendous amount of power these days. As the processors and components get more powerful, so does the amount of energy they need to consume. Some desktop systems now can consume almost as much power as a microwave oven. The problem is that even though your PC may have a 500W power supply, the amount of power that it actually pulls from the wall could be much higher than this. This articles takes a look at how much energy a power supply uses and what consumers can do when making a purchase to try and reduce that consumption.
Power In Versus Power Out
The electrical power that is supplied to your house runs at fairly high voltages. When you plug your computer system into the wall for power, this voltage does not flow directly to the components within the computer.
The electrical circuits and chips run at much lower voltages than the current coming from the wall outlet. This is where the
Understanding PC PSU Wattage Ratings
Introduction
Pretty much every power supply on the market for a desktop PC computer is advertised solely on its wattage. Unfortunately, this is a simplistic view of a very complex issue. The power supply is there to convert the high voltage from the wall outlet into the lower voltages required to operate the computer circuitry. If this is not done properly, the irregular power signals that are sent to the components can cause damage and system instability. Because of this, it is important to make sure you buy a power supply that meets the needs of your computer system.
Peak vs. Maximum Wattage Output
This is the first real big gotcha when it comes to looking at power supply specifications. The peak output rating is the highest amount of power the unit can supply, but this is only for a very brief time.
Units cannot continuously supply power at this level and if it attempts to do so will cause damage. You want to find the maximum continuous wattage
Power supply units (PSUs) are often overlooked when building a computer system. A poor quality PSU can greatly reduce the life span of a good system or cause instability. A high quality PSU can also help reduce the noise or heat generated within a computer system. Whether you are buying one for a new computer or replacing a old unit, here are some tips for purchasing a PSU.
Avoid Power Supplies Under $30
Most power supplies that are priced below $30 generally do not meet the power requirements of the latest processors. To make matters worse, the components used in them are of inferior quality and more likely to fail over time. While they may power the computer system, inconsistencies in the power to the components will tend to cause instability and damage to the computer.
ATX12V Compliant
Developments in processors, the PCI Express bus and graphics cards have all increased the amount of power required to operate them. To help provide this extra power, the new ATX12V standard was deve

This is my 13.8V 25Amp power-supply. With over-current (26 Amps) and over-voltage (16 Volts) protection.
Uses fold-back current limiting.
Short circuit current is around 8 Amps.
Uses 3 (or 4, which is better) IRF150n power MOSFETs as pass transistors. LM723 can drive the MOSFETs directly.
Needs big heat-sink, 1.2 C/W for the FETS and bridge rectifier, or forced air cooling.
Yes, the MOSFETs need equalizing resistors (0.1 Ohm 5 Watt) if they are not closely matched. Short circuit current of 8 Amp must be divided between the 3 MOSFETs, as the total power dissipated is 160 Watts. Better is to use 4 MOSFETS’s to lessen the stress during short circuit.

Now if you are competent to build a 4.5V to 25V variable power supply capable of supplying 10 amps then the above information is all you need. On the other hand if the above leaves more questions than were answered then obviously you need more experience. The little schematic above, as a project, would run into hundreds of dollars to build.

This circuit provides 0-30 volts, at 1 amp, maximum, using a discrete transistor regulator with op-amp feedback to control the output voltage. This power supply has constant current mode suitable for charging batteries.
With reference to the schematic, lamp, LP2, is a power-on indicator. The other lamp (lower) lights when the unit reaches its preset current limit. R5, C2, and Q10 (TO-3 case) operate as a capacitor multiplier. The 36 volt zener across C2 limits the maximum supply voltage to the op-amps supply pins. D5, C4, C5, R15, and R16 provide a small amount of negative supply for the op-amps so that the op-amps can operate down to zero volts at the output pins (pins 6). A more modern design might eliminate these 4 components and use a CMOS rail-to-rail op-amp. Current limit is set by R3, D1, R4, R6, Q12, R10, and R13 providing a bias to U2 that partially turns off transistors Q9 and Q11 when the current limit is reached. R4 is a front panel potentiometer that sets the current limi

By Guy, de ON6MU
This is an easy to make power supply which has stable, clean and regulatable output voltage. By using two 2N3055 transistors we become more then 2 times the amount of amps then the power supply delivers, making it real though to brake ;). Although you could use this design to deliver 20 amps ((with almost no modifications and with a proper transfo and a huge heat sink with a fan), I did not needed such much power. Make sure you mount them on a huge heat sink, as the 2N3055 transistors can get very hot at full load.
Although the 7815 power regulator will kick in on shortcircuit, overload and thermal overheating, the fuses in the primary section of the transformer and the fuse F2 at the output will secure your power supply. The rectified voltage of: 30 volt x SQR2 = 30 x 1.41 = 42.30 volt measured on C1. So all capacitors should be rated at 50 volts. Caution: 42 volt is the voltage that could be on the output if one of the transistors should blow.

The circuit described here is a full wave voltage doubler. The output voltage is twice the input voltage. For 230V AC input the output will be nearly 600 Volts.
Resister R1 is used to limit the initial high voltage and high currents. Capacitor C1, C2, C3 together with coils L1 and L2 form input line filter. The capacitors C4 and C5 protects diodes from high voltage transients on the AC line as well as reduces inter carrier hum modulation of the R.F picked up by the mains. Capacitors C6 and C7 provides enough filtering for the output DC Voltage.
