atx p4 power supply

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

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

in the country, but the price is very affordable, because the price is low, the profit is less, the company's staff treatment is generally low, this is the force for the company often have employees resign the main factor, From which I also realized what kind of power better, here to talk about personal experience: a good power supply must have PFC,PFC is a stan

by Intel in. The output power is generally ~ Between. The ATX Power Supply usually uses a 20Pin (20-pin) double-row rectangular socket to power the motherboard. With Intel's Pentium4 processor, the power specification is changed

, the output line switch to a dual-row 20-core plug to the motherboard power supply. Some ATX power supplies have a switch under the output socket that cuts off the AC power supply and shuts down completely. Intel l997 February l

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

"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

follows. +12V≥18A, you can choose any one of the cpu;+12v≥14a on the market, you can choose Intel Celeron D and P4 processor, +12v≤14a can only P4 low speed and normal Celeron. We suggest that we should tailor it to avoid unnecessary waste. You can also calculate yourself according to the following formula: (CPU Power consumption W1/12) +2A (motherboard VR

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

monitor output voltage and current exceed rated value, IC through feedback circuit feedback back to adjust the internal control circuit, control Q1 and Q2 duty ratio, always keep output constant voltage and current supply CPU. Maintenance process The first manifestation of the failure is that the CPU core voltage (VCore) is not normal. And there are two things: The first is: CPU core voltage High or Low: Voltage bias High Check whether the Q1 bre

In recent weeks, frequent video card failure, in the normal operation of a sudden black screen, and then the boot BIOS has a long two short sound alarm, indicating that the video card failure. S

The company's computer is idle with two hard disks. I want to put these two hard disks on a celon D machine. This machine has a power supply of 250 W, it is estimated that the actual output power may be less than 200 W. A hard disk and an optical drive were previously attached. After the hard disk is loaded, the machine starts and can identify three hard disks a
