atx power supply specification

Do you want to enable a power source without a motherboard? 20 pin atx has a sticky port on it, which is facing itself. Then, the number on the left is 4th in the lower row, and the number on the right is 4th in the lower row. Green and any one black. Black is the ground! Note:1. The PC power supply is a conversion

One day, I repeatedly started the machine several times, and then pressed the power key, but it didn't respond. After my check, it turns out that the power supply is not working and there is no voltage on all the feet.At first, I thought the fuse was burned out due to frequent start, but I took the power off and saw th

Are you going to have a power supply to get him powered on without a motherboard? The ATX 20pin has a non-stop bayonet on it, and it's facing itself, and then it's down to the left of the line. 4th and right, 4th, get these 2 connected. Green and any one black, black is ground! Special attention: 1, the PC power

A search on Google found an ATX switching power supply consisting of TL494 and LM339 At first glance, more than 3842 of the switching power supply to be more complex in fact, as long as the basic circuit has a certain understanding and a certain imagination to understand

most of the current power supply fan design for the blow or side blowing mode, if it is on the blow, the fan is fixed in the power supply cover, when the demolition, it is important to note that the fan also has a power cord connected with the internal PCB, demolition, shou

Most servers are configured as 24-hour running devices. Therefore, server energy-saving technologies are more important than personal products such as PCs and laptops. Generally, there are two kinds of energy-saving technologies on servers. One is energy-saving technologies for processors, such as the Power Islands technology used by IBM on Power5, Intel's SpeedStep and AMD's PowerNow! The other is power

power will be directly burned off. So the power of the best state of the work in the rated power state, the occasional overload is no problem, but also does not rule out the stability of the problem. Calculation of rated power of non-standard rated power

What to do if the laptop motherboard is out of power: First step. First, pin 14 and 15 short, and if the fan on the ATX power supply rotates, skip this step and look at the next one. If the fan on the ATX power

supply is to convert a 220 v ac to a DC power available for the PC. Generally, the power supply converts an AC to 12 V, 5 V, or 3.3 v dc. 12 volt DC is used to drive a device with a motor, such as a hard drive and a CD-ROM drive. 5 V and 3.3 V output are used to supply diff

. Assume that the output voltage accuracy is ± 2%, then the output voltage lower limit vo1 = 4.9 V, CO = 40000 UF, there are: 0.5 * Co * (Vo2-Vo12) = rjt1 * Po ...... (2) the substitution values can be: T1 = 1 ms. We found that the output capacity of UF is extended, and the power loss duration is only 1 ms! It can be seen that increasing the output capacitor has little impact on the power-down duration. 3.

In the last few installments, we have installed the main parts of the chassis, which will teach you the power source for installing your computer. One, from the appearance of recognition power supply Probably a lot of people know that the main power supplies are: at power

capability--look at the power supply standard We know that Intel has a series of design recommendations and reference specifications for computer power supplies, which is the ATX12V standard, which defines the physical dimensions of power supplies, thermal requirements, configuration of various connectors, electrical

The ATX Power specification is the motherboard and power structure standard established by Intel Corporation in 1995, and the ATX is an abbreviation for English (at Extend). ATX Power s

"Fault phenomenon" a computer recently connected to the power on its own boot, sometimes inexplicably on the boot. "Failure analysis and processing" causes this kind of failure may have the following: (1) First check whether the computer in the BIOS setup will be timed to boot function set to "Enabled", so that the computer in the set time automatically boot. (2) Again check whether the computer in the BIOS setup item to open the function of the call

Offline Live detection Under normal circumstances, in standby state of ps-on and Pw-ok two power signals, one is high, the other is low level, plug 9 feet only output +5VSB voltage, as long as the meter to measure the voltage to the parameter value, you can determine the result of the problem. Artificial Wake power supply detection Use a thin wire (such as a p

jinhetian Jinba ATX-S388 power saving Master, professional design for Internet cafes, not only powerful power, but also wide voltage design, effective to prevent computer damage caused by voltage problems. The standard power-saving Master also features a patented technology that adds an energy-saving

Seagate Hard Drive, and then upgraded with a 128M memory, configured with a built-in 56KMODEM and TV card, The fault appeared. Specific performance for the system started shortly after the crash, the monitor black screen no signal, the optical drive light long bright. Whether into the WIN98 system, with the system disk boot, or into the CMOS system will appear this fault, once the crash either reset key or power button can not shutdown, only pull the

the ATX power supply to the motherboard plug can not unplug the measurement, therefore no measurement. Analysis of the machine has more than two years and the internal configuration of the Board more, power supply in the long-term high-load operation may be the

Study on the application of Poe power supply (I.) Introduction to Guan Jinssong PMP 2010-4-2 Poe POE refers to the transmission of data signals to some ip-based terminals (such as IP telephones, wireless LAN access point APS, network cameras, etc.) while the existing Ethernet CAT.5 cabling infrastructure is not changed Ethernet It can also provide DC-powered technology for such equipment. Poe technology can

, which is our only choice when the Judge standard. For example, the rated current of a 8 cm 12V DC fan used in general power supply is usually between 0.12~0.18a. Four, the Power supply safety specification PC power
