There is a fair bit of wiggle room on and above the board, so you can fudge a little on the cap dimensions. In particular, the cap they used for EC12 was a very short "low profile" one which I was unable to find; however I was able to fit a "normal" sized 100 µF cap from my parts bin with no trouble. | |||

The VIA EPIA CN is a Mini ITX mini PC based on the VIA C7 processor.
Known Issues
Symptom or Problem Encountered
Machine powers down unexpectedly and/or is generally unstable. Out of spec values for voltage rails are shown In the PC Health Status screen of the BIOS.
Causes
- Failing capacitors on the power supply board and/or a failing power brick
Solutions
- Replace capacitors on the power supply board. May also need to replace the power brick.
Original Parts
Power Brick
This device came with a 19 V 4.74 A power brick. Barrel plug is 5.5 mm OD x 2.1 mm ID, and is center (tip) positive.
Power Supply Board
Power supply board is labeled "Migrus C5" and is located in the front left corner of the case.
| RefDes | Qty | Capacitance | Voltage | Mount | Diameter/Size | Height | Lead Spacing | Temp | Type |
|---|---|---|---|---|---|---|---|---|---|
| EC1, EC3, EC7, EC11 | 4 | 2200 µF | 25 V | Through Hole | 13 mm | 22 mm | 6 mm | 105 °C | Electrolytic |
| EC12 | 1 | 100 µF | 25 V | Through Hole | 6.5 mm | 7.5 mm | 2.5 mm | 105 °C | Electrolytic |
| EC13 | 1 | 680 µF | 10 V | Through Hole | 8.2 mm | 12.7 mm | 4 mm | 105 °C | Electrolytic |
| EC2, EC6, EC8, EC9, EC10 | 5 | 1500 µF | 16 V | Through Hole | 10.3 mm | 21 mm | 5.5 mm | 105 °C | Electrolytic |
| EC4, EC5 | 2 | 470 µF | 16 V | Through Hole | 8.25 mm | 12.5 mm | 4 mm | 105 °C | Electrolytic |
Replacement Parts
Power brick
Any 5.5/2.1mm center (tip) positive power brick rated at 19 V and at least 4.74 A should work. The author of this page is using this Nobsound power adapter and it is working well.
Power Supply Board
There is a fair bit of wiggle room on and above the board, so you can fudge a little on the cap dimensions. In particular, the cap they used for EC12 was a very short "low profile" one which I was unable to find; however I was able to fit a "normal" sized 100 µF cap from my parts bin with no trouble.
