    Power supplies - cases and shielding

    I got this ECS K7SOM+ that I want to make a custom slim case that will attach to the back of a monitor.

    The motherboard has a soldered on XP 1600+, and is just a little smaller than micro-atx. What I wanted to do was take this astec 200W power supply from a hp and power it with it. The internals come to a total height of about 1 3/4 inches to the top of the heatsinks/primary caps.

    What I wanted to do is take it out of the psu casing, flip it over, glue a piece of plastic to it to prevent shorts, and place it upside down over the pci slots, and a little over the edge of the motherboard (see pic)

    Am I going to run into any trouble trying this?

    Keep an eye on the airflow going through the power supply. Since it is being mounted upside down, and heat rises, it has huge potential to trap heat from the PSU components as well as the motherboard.

      Induced currents from the PSU without its shielding will wreak havoc with the mobo.

          Thought so.

          External shouldn't be a problem, right?

          Maybe I will just screw it to the outside to keep it all grounded.

            Still need to build a custom metal case for PSU and *still* need a fan to move air through a complete system. I tend to modify the PSU case, some metal for PSU is so TOUGH.

              Vizio e601i-A3 - Has Sound and Display, But No Backlight - Bad Power Supply Board or Bad LED Bulbs ?
              by Tynan Dill
              I was given this TV from my great uncle. He said it just wouldn't turn on one day out of nowhere, replaced the TV, and gave it to me to possibly fix and use for myself.

              Upon bringing it home and plugging it up, it showed a standby light.

              I powered it on and without a flashlight, the display showed the "V" but the lighting is very dim, but visible.

              The screen seems to blackout and stay black, but with a flashlight I can see the display.

              With my Playstation 4 connected via HDMI, and running a game I can hear sound.

              Assuming...

              Asus Probook P5440UF-XB74 power issue
              by GLISIT
              Hi all,

              TL;DR - this laptop is driving me nuts with the oddball power-related behaviors. Appreciate any insight you can provide!


              I'm experiencing a power issue on an Asus Probook P5440UF-XB74. Although I've worked with electronics and computers for decades, this is my first attempt at getting into motherboard-level component troubleshooting. Any help the community can provide is greatly appreciated!

              A few weeks ago I was using the laptop (on battery power) for a Zoom meeting. The battery was running very low (long meeting) but I wasn't worried about...

              Vintage AT Power Supplies - Selecting Capacitors
              by iMic
              Hi,

              Back after a long hiatus with some old power supplies that need repairing. I've recently picked up a couple of 386SX systems, two 486DX systems, a SiliconGraphics Indy and an iMac G3 that either have verified leaking capacitors in their power supplies, or are likely to in the near future. For the sake of simplicity, instead of tackling all at once, I'm starting with the 386's and one of the 486's.


              The 386's power supplies are Seasonic SS4040A's, with caps that are visibly leaking, and 9 replacement caps per unit are required. Most appear to be from the Rubycon...

              by meraklinetx
              Hello, I have an asus Z97-A motherboard and it doesn't start which was working properly before, the problem isn't related by ram, ram slots or psu (I changed all and nothing work), the exact problem is when you switch it on , it starts and after 1 seconds (no boot or display picture) it's off and then on cycle continuously until you power it off from psu also it's responding to the power switch for turning it off if you keep pressing it 3 or 4 seconds (power button pin has 3.3v) , also when you start it with eatx 12v socket connected this is happening (power cycle also all voltages are resetting...
