It is feasible to supply computer with al power supply. One power supply for the original host, and another for the graphics card. This method can be used to solve the problem of insufficient power supply
the key problem is to synchronize the two power supplies when they start. Two wires can be used to connect the "green line" and "black line" on the 24pin main plug of two power supplies. All black lines are connected to the public
it should be noted that the line should be connected correctly, and the voltage should not be too large to cause power failure

1, daily cleaning
< P >
there are many computer management tools in the market, such as 360, computer housekeeper and a series of management tools. According to personal preferences, you can use these software to clean up the registry, boot key, etc. to improve the boot speed or rece the useless temporary files and cache files on the disk
< P >
new computers must be reasonably partitioned, because the system will default to the system partition for file exchange, virtual memory, etc. So give Disk C a little more space. Today's computers basically have 1t space, about 70g ~ 100g for disk C

usually
5, hardware maintenance computer is too laggy for
computer chassis. This will affect the heat dissipation of the machine. After overheating, the parts will rece the working frequency automatically to protect their hardware from overheating and burn. It will feel that the computer will be slow and very stuck. p>
therefore, it is recommended to clean the st in the computer every six months to prevent the st from accumulating on the cooling devices such as fans. At intervals, the computer screen and keyboard should be wiped with a special cleaning agent for the computer
3. 1. Parallel connection of green wires
firstly, remove the pins on the green junction (PS on) on the 24pin interface of the two power supplies with a needle withdrawing device, then cut off the pins on the green wire of the auxiliary power supply, then weld the pins on the green wire of the main power supply with an electric soldering iron, and then insulate them with a heat shrinkable tube to prevent short circuit, Finally, the modified green line is installed back on the 24pin interface of the main power supply to complete the parallel transformation of the green line
2. Parallel connection of black wires
players who have removed the power supply all know that the black wire (GND ground wire) of the power supply is grounded at the screw fixing hole of the power supply PCB and the shell, so the black wire parallel connection between the two power supplies can be realized by connecting the shells of the two power supplies with wires
3. Platform installation test
after a series of wire parallel modification, the parallel connection of al power supply is completed. Next, according to the idea of operation, connect the power supply of the main board, CPU and hard disk to the main power supply; The auxiliary power supply of the graphics card is connected to the auxiliary power supply through the double large 4Pin to 6pin adapter line. After confirming that the connection is correct, plug in the power supply, and then use a screwdriver to short circuit the start pin on the main alarm. With a click, the host starts smoothly
it is recommended to connect the hard disk to the main power supply, because there is a gray line in the 20pin (or 24pin) interface of the motherboard, which is the P.G signal line, which means power good. When power on, the power supply will send P.G signal to the motherboard after the output is stable, then the motherboard will start self-test. When the power is turned off, before the voltage drops to 75%, the power supply will also send a P.G signal to the motherboard to let the motherboard hang up the hard disk head. Because the auxiliary power supply is not connected to the motherboard, it is unable to send this P.G signal, so the hard disk should not be connected to the auxiliary power supply to avoid damage to the hard disk
it should be noted that the 220 V power supply of the two power sources must be connected and turned off at the same time. If one of the two power sources is connected or cut off first, the 220 V power supply will start automatically
conclusion: Although the al power supply can operate stably for the time being, it is easy to cause more hardware damage e to the damage of one power supply. And when the two power supply linkage, the conversion efficiency is very low, the power consumption will be a part of the second power consumption. In general, al power supply scheme is only suitable for temporary replacement of single power supply

4. The double power supply of computer mole needs to perform the following operations:
1. Parallel connection of green lines
firstly, the pins of the green junction (PS on) on the 24pin interface of the two power supplies are removed by using the needle withdrawing device, then the pins of the green line of the auxiliary power supply are cut off, and then the pins of the green line of the main power supply are welded with an electric iron, and then the heat shrinkable tube is used for insulation treatment to prevent short circuit, Finally, the modified green line is installed back on the 24pin interface of the main power supply to complete the parallel transformation of the green line

6. The process of making desktop computer al power supply system is as follows:
1. Set the computer 220W power supply as the main power supply, and supply power to the motherboard, CPU and hard disk. Set the 220W power supply as the secondary power supply, and supply power to the graphics card separately, and then connect two power supply green lines and black lines to make the two power supplies work synchronously
2. Remove the needle from the green knot on the 24pin interface of the two power supplies with the needle withdrawing device, then cut off the pin of the green line of the auxiliary power supply, then weld it on the pin of the green line of the main power supply with an electric iron, and then insulate it with a heat shrinkable tube to prevent short circuit.

8. Ha ha, I have the same idea! One Weixun 300W is used as the main power supply, and one delta 200W small power supply is used as the video card power supply. Chat slowly:
1. The power consumption of hd6790 graphics card is only 150W. The 200W you checked should be the power consumption of the whole machine when the graphics card is full load (CPU is not full load)
2. Don't you think x2 5000 + with hd6790 is a little bit of a horse pulling a cart? Ha ha, it's off topic. I won't say more
3. The peak power consumption of Jinhe Tian power supply is not the power consumption that can be operated for a long time. The maximum current of 12V is 16A. When it comes to 16a, it will start the current limiting protection mechanism. It doesn't necessarily mean that it can output 16A stably. According to Jinhe Tian's personality, I estimate that the maximum output of 12V power supply is 150W
4, 4Pin interface. According to your description, "the maximum output current of + 12V is 16A". This is a single 12V power supply. The 24pin of motherboard is not separated from the 4Pin of CPU. In that case, all 12V can be output from 4Pin in theory. But the output power is definitely not 350W, at most 150W. The first reason is that 350W contains 100W contributed by + 3.3V and + 5V, and the second reason is that the virtual scale of power supply
5. The PCI-E graphics card has two power supply sources, which are connected to the motherboard through 24pin. The maximum power supply of PCI-E slot is 75W, and the excess part comes from the external power supply of the graphics card. So this Jinhe Tian power supply alone to power the graphics card, in theory is enough
6. Connection of al power supply. In theory, you only need to connect the signal control line (gray one) in the 24pin and the ground wire with the gray line of the auxiliary power supply (two power supplies in parallel). But in fact, the 12V deviation value and ripple of the two power supplies may be different, or the turn-on time may be slightly different. Will this affect the graphics card? I don't know. I'm also obsessed with this problem, so I haven't started to change it. Hd6790 is not cheap. LZ is cautious
7. Another more reliable method is to use one power supply for CPU, motherboard and graphics card, and auxiliary point power supply for fan, hard disk and optical drive, which should rece the risk. But how much power does these drives consume? Ha ha, the key is the graphics card
PS: if you don't plan to set up a al graphics card in the future, 500 W power supply will be enough. Antyk vp550 plus, 400 yuan can do it!

9. You can't use al power supply. If the power is too high, some chips on the motherboard can't bear or convert so much voltage. It's recommended to choose one with stable voltage and higher power.
