insert cap table here
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 is hard to find, and was easily replaced with another (more "normal" sized) capacitor of the same values.

The VIA EPIA CN is a Mini ITX mini PC based on the VIA C7 processor.


Processor: VIA C7 @ 1 GHz (x86 w/PAE)

Chipset: VIA CN700 North Bridge, VIA VT8237R-series South Bridge

Graphics: Integrated C-Pro AGP with MPEG-2 Acceleration

Audio: VIA VT1618 8-channel AC'97 codec

Memory: 1 x 240-pin DDR2-533 (PC2-4200U DIMM (maximum of 1 GB)

Slots: 1 x PCI (broken out to 2 x PCI using riser card)

IDE: 2 x UltraDMA 133/100 controllers

LAN: VIA VT6103 10/100 Ethernet

TV Out: VIA VT1625 HDTV Encoder

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

Closeup view of the PSU board

Power supply board is labeled "Migrus C5" and is located in the front left corner of the case.
