Just a heads up, I will be taking Inuvik down for about 4 hours tonight to replace a power supply. It was initially very spotty after I brought it back online after a month or so of downtime to get a working motherboard in place, but after a week or so settled down.
This is typical of failing electrolytic capacitors, the plates will deform when there is no power and they will have leakage and less than their rated capacity when first used, but with power over time their plates will reform. But they are on their way out and will eventually fail hard, and on a 1kw power supply, a short circuit is not something you want.
Therefore I am going to replace it tonight, actually changing it out for a Seasonic 1200 watt with a 12 year warranty, so hopefully won’t have to deal with this issue on this machine again any time soon.
