To find PC power supply problem, do not open it and try to repair, as pass through the high voltage. Such work should be performed only experts who know a lot about this case. (more…)
This article will discuss about the alert function of pc power supply. The main voltage power supply, which supply the computer is +12 volts. Power supply for this circuit should provide a large output current, especially in computers with lots of drive bays. 12 V is applied also to the fans, who tend to work all the time. Usually, the fan motor consumes between 100 and 250 mA, but with newer computers, this value is less than 100 mA.
For fanless unit X-400 is a bit unusual: no walls, as expected, perforated, but where's the huge heat sink that forms the top cover? Without a doubt, Seasonic X-400 Fanless could surprise : externally it is more like a normal block, which forgot to put a fan than a model that could be given without the fan to four watts of power. However, he - can. Moreover, with the X-400 Fanless shows excellent electrical characteristics and features a fully
The appearance of the block is sufficient for typical fanless models mesh body, covered from top to a massive aluminum heatsink. Immediately we can notice that the radiator fins are frequent and low, and therefore the most favorable work for him - blowing weak air flow, for example, the case fans. Although in theory the fanless power supplies can operate without any air flow, at least one low-speed fan inside the computer is better to have - it will
Power Supply FSP Aurum and Aurum CM left a very ambiguous impression. On the one hand, it is clear that engineers, designers and marketers FSP Group have invested in them, if not the whole soul, then at least most of it - blocks of neat, handsome, beautifully decorated in terms of visual aesthetics, and the availability of useful information, they are made on the new platform, demonstrating excellent efficiency and other parameters are good ... So, if you select
Feature of this transistor compensation voltage (see picture) - used in the feedback field effect transistor VT3, which acts as a dynamic load for the transistor VT2. Because of this factor increases the voltage regulation: when the input voltage from 11 to 19 V output voltage varies within ± 60 mV. Rated output voltage using Zener type D814B is 9 V. (more…)
The ATX power supply generates three main voltage outputs that are: +3.3 V ; +5 V ; and +12 V. Low-power −12 V and +5 VSB (standby) supplies are also generated by this power supply. The −5 V output was originally needed since it was supplied on the ISA bus, however it became obsolete with the removal of the ISA bus in modern day PCs and has been removed in later versions of the standard ATX power supply.

Why PC power supply..? Here the answers: A fact that standard PC power supply is very cheap. The new PC power supply will cost you about US$10 - US$15, but a bench lab power supply cost you about US$ 100. You may use your unused old computer power supply Has regulated and very stable output voltage (+/12,+/-5, +3.3VDC general) Has very high current DC current output Has a "box" which very easy to modified (more…)
