I think the cause can be the PSU is dying.

I found this post and want to try to replace the original PSU with a 220W FSP220-60LE flex ATX PSU as Sonicboom did, but I'm not an expert at electronics like people here so it's difficult to me to understand some information, like this part:

Quote:

The C2 motherboard uses a 6 pin connector that I din't have so I cut the wires about 2 inches from the PSU so I could solder the new PSU to them.

-12=BLUE
+12=YELLOW
+5=REDx2
0V/COM=BLACKx2

Power on is GREEN and needs to be connected to a BLACK wire to power up the unit. This could be wired to a switch and mounted externally for convenience....or just use a dedicated power strip or even a smart plug maybe.

Do I need to select only 6 pins from the 20 available in the molex connector from the new PSU?
And what about the "power on" connector? The green has to be connected to green to turn off the unit and to black to turn on the unit? So... if I use a dedicated power strip for shutting down the unit, it doesn't matter if I let the green soldered to that black pin? Then the power button will not work anymore (so there will not be standby mode) and all the time the power led will be green color? For that purpose, is it an additional 7th pin to use (the 3rd black) or it's one of the two previous black pins?

I'm very sorry if my English is far from perfect and I'm asking a lot of questions.

Greetings and thank you very much for your help.

Update December 2022 I finally replaced the original 200W Channel Well PSU with a 220W FSP220-60LE flex ATX PSU. The original had begun to cause visual distortions so it had to go. I bought the replacement on Amazon for maybe $60 about a year ago. The original provided 13A@5V and 15A@12V while the replacement provides 16A@5V and 16A @12V. Even the -12V rail increased from 0.3V to 0.8V. The fan seems to be a little quieter too. After some basic reading I learned that the original PSU followed the standard color coding for the wires and their voltages. See the image for reference: Attachment: connector_atx_pinout.gif [ 21.47 KiB \| Viewed 1693 times ] The replacement PSU has a 20 pin molex connector (as in Version 1 above) with all the connections necessary. It also followed the standard color coding. I verified the correct voltages with a DMM prior but all I had to do was match the colors. The C2 motherboard uses a 6 pin connector that I din't have so I cut the wires about 2 inches from the PSU so I could solder the new PSU to them. -12=BLUE +12=YELLOW +5=REDx2 0V/COM=BLACKx2 Power on is GREEN and needs to be connected to a BLACK wire to power up the unit. This could be wired to a switch and mounted externally for convenience....or just use a dedicated power strip or even a smart plug maybe. Seems to work just fine. I noticed that after about 12 hours the fan was definitely still running while the C2 was turned "OFF". I hope this thing lives a long life. The MTBF is 100K hours so that's 11.4 years at 24/7 use. Even at 1/4 I'm happy

I have a Crystalio II VPS-3800 that I bought second hand. The installed firmware is version 2.10. It was working perfectly for the first 30 minutes; then it began to do weird things: The green led of "Power" blinks, the LCD screen also blinks, the unit resets itself, some times it doesn't power on and remains at standby mode with the led in red, it hangs randomly and show graphical glitches before that, it doesn't recognize the input signal most of the time, the internal HDD seems to be trying to work without luck (I can hear it connecting and desconnecting all the time), ... I think the cause can be the PSU is dying.

Open the case and disconnect the HDD for now. It will cause problems on start up especially if the HDD is damaged from shipping or the PSU is dying. Remove it completely. My C2 was packed poorly and the HDD was clicking on start up and the C2 would not start up normally until I disconnected the HDD. After that it powered up fine. katsura82 wrote: I think the cause can be the PSU is dying.

Greetings and thank you very much for your help. Your English is amazing, please don't worry about that. I can understand Spanish also but prefer English... After you open the case and remove the HDD, carefully disconnect the old PSU from the motherboard. You'll notice the six colored wires on the Molex connector. Keep the Molex connector and the 6 wires that are in it. Cut them off from the old PSU. You should now have a connector with 6 wires about 2-3" (~7cm). Strip the ends of the wires about 1 cm exposing the wire. Now you're ready for the new PSU. YES, connect green and black to power on the new PSU. They are right next to each other. This is required and has nothing to do with the power strip. All you need to know is that you have to connect the green to the black. Put some electrical tape around it to protect it from shorting out! Make sure NONE of the exposed wires are touching the metal case. On your new PSU follow the colors for the wires in the graphic from my last post. The colors should match the 6 wires you have. I used the wires from the main bundle of 20. You only need the 6 wires of the same color for the C2 plus the green/black for power on. 8 total. You don't need any other wires from the new PSU. Study that graphic and if possible, test the voltages with a multimeter to confirm you have the correct wires. You want +5VDC not 5VSB (red wire NOT purple). I think you bought the same one I did. If so, the colors should be the same. The colors are standardized to be the same. To test them make sure the green and black are connected and then insert the power cable and then plug it into the wall. It should turn on. From there you can measure the DC voltages. Don't worry about amps, just confirm 12V and 5V. The new PSU can be tested before you install it. Put it on a table or something to test. Be careful while its plugged in... You should solder the wires together and put heat shrink over the connections. If this isn't an option simply twist the wires together and use electrical tape to protect the connections. That is not my favorite method but it will work... Good luck! Feel free to message me if you need help. Post photos here if you can.
