With no markings, taking it to Radio Shack will not work, there is no info on what we need, can't tell by looking at hub. djp

How to increase power on my daystate mk3


Basic power supplies should be 400 to 1000 Watts for current systems. A 230W supply is Underpowered and may not support the hardware devices all that well. In addition, the Video drains power, so a Video card with 2G Ram will help speed up the process. Then an additional Power RAM (Memory) with speed available to your system; helps increase activity. Cooling Fans help reduce HEAT that also slow down operations. Clean the inside of the computer as dirt., dust and dust balls collect and keep the electronics hot.

Ac adapter is red, what should i do?


This problem occurs when the power supply detects a problem. The power supply has several built-in safeguards to help prevent damage to either the console or to the power supply. The power supply will turn off if:
  • There is too much current.
  • The voltage is too high.
  • The temperature of the power supply is too high.
When any of these things happen, the light on the power turns red.
Solution 1: Make sure that the power supply is cool loadTOCNode(2, 'whattotry'); The red light might indicate that the power supply is too hot or that it has overheated. Follow these steps if the power supply light is red:
  1. Turn the console off.
  2. Disconnect your Xbox 360 Power Supply from your Xbox 360 console and from the wall outlet.

    Collapse this imageExpand this image unplugpowersupply.jpg

  3. Let the power supply cool for two hours in a well-ventilated space. Do not connect the Xbox 360 power supply to the console or to the wall outlet during this time.
  4. After the power supply has cooled for two hours, reconnect the power supply to the console and to the wall outlet, and then turn the console on.
If the power supply light is still red, try the next solution.
Solution 2: Make sure that the power supply is plugged in loadTOCNode(2, 'whattotry'); Make sure that the power supply is directly plugged into a working wall outlet. Problems might occur with the power supply if it is connected through an extension cord or surge protector.

If the power supply light is still red after you connect the power supply directly to a working all outlet, try the next solution.
Solution 3: Plug the power supply into a different wall outlet loadTOCNode(2, 'whattotry'); To check the possibility that the wall outlet you are using is faulty or that there is a blown fuse, plug the power cord into a wall outlet that you know is working.

If this does not solve the problem, try the next solution.
Solution 4: Order a replacement Xbox 360 power supply loadTOCNode(2, 'whattotry'); If you've tried all the solutions above and your power supply light is still red, you should contact Xbox Support to order a replacement power supply.

To help the power supply work correctly, follow these guidelines:
  • Do not block any ventilation openings in the power supply.
  • Do not put the power supply on a bed, a sofa, or on any other soft surface that might block ventilation openings.
  • Do not put the power supply in a confined space, such as a bookcase, a rack, or a stereo cabinet, unless the space is well ventilated.
  • Do not put the power supply on a stereo speaker, an amplifier, or a heat source such as a radiator or a heat register.
  • Do not use an unlicensed accessory, such as a third-party power supply or any accessory that plugs in between the Xbox 360 console and the power supply.
  • Plug the power supply directly into a working wall outlet. The power supply might not work correctly if it is connected to an extension cord or surge protector.
hope this helps.

Hi I try to troubleshoot the ASTEC 450W power supply. I don't know how to power up. Anyone can help me with this problem. Thanks. My email is trinhluu62@yahoo.com


DO NOT troubleshoot a power supply unless you are professionally trained. Power supplies contain a lethal charge even when disconnected from a power source and should never be opened or tampered with. If you are having a problem with building/upgrading a PC and are using this power supply, then please post further details on your problem here and maybe we can help.

I need an ASTEC power supply model SA147-3506 for IBM P-2 computer, Can anybody help me??!!


145 Watt power supply with the old style AT motherboard power cable connectors. (2 Each)

http://www.playtool.com/pages/psuconnectors/connectors.html#oldpc

I just put Astec SA147-3506 in my browser search bar, and came up with a number of search hits. Prices ranged from $50 to $170!

And it's a 145 Watt power supply! Astec is a cheap quality power supply manufacturer, to boot!

You know, there is a way to use a newer reliable power supply, and the AT power supply motherboard connectors, off of the power supply you have.

It's not for the squeamish, but can be done.

The power wires are removed from the ATX power supply motherboard cable connector, of the new power supply, and inserted into the AT power supply connectors.
(ATX 12V power supply is the newer one. AT power wires removed from the P8, and P9 connectors of your old power supply)

Interested?

Hello,

You can replace the pc with the same watt power supply or upgrade to around 420W and still be able to run your system within thermal threshold. The power supply should be a 20-pin ATX power supply.

Good Luck

Power supply not working


Hello my friend, if one of your power supply's part is burned, your power supply won't work else if its work i has a short time to operate and it will be burned the whole board of your supply. Mainly the reason of burning your supply are the following: 1. The Electric supply  from the source is to high or above the limitation of your Power supply. 2. Your power supply is over capacity. 3. You're power supply board develop a liquid moisture inside that is why it shorted and eventually the board is burned.  4. The load of your power supply is overload due to some device you attach that is beyond to the limit of your power supply's wattage capacity.
Note: try to see the wattage or voltage or the capacity of your power supply can supply the electricity within your computer system. To ensure that it does not exceed the limit of your power supply's limitation.  I therefore reccomend that to avoid burning the entire power supply board from short circuit, it is recommended to replace your power supply to avoid incidents may arise.
Hope this advice helps your problem. If you need more assistance just reply to this post.  If this solution or recommendation is able to solve or help your problem then please rate it.  Thanks
