    Can the symptoms this person is reporting be a sign of bad caps in the PSU?

    http://www.ocforums.com/showthread.php?t=433846

    Said that the PSU was fine for at least approximately 1 year and that afterwards, the +12V rail spikes up to at least 13V then shuts off.

    Possibly... the caps in them are all Teapo, and the PSU has cooling issues with the intake fan blocking all ventilation to the secondary side.

        Aye

        The intake fan on these is fitted right up against the secondary heatsink, leaving perhaps a 1/8" space on the extreme edge of the fan to get air into the secondary side. As one might expect, the secondary side then gets hot and since the fan controller is on that heatsink, the fans start spinning up to very audible levels.

        On mine, I moved the fan to the outside of the PSU case - it runs much cooler and quieter that way. At the moment, the exhaust fan is barely pushing any air at all, and it's nice and cool.

        Edit - forgot to mention the secondary side has a huge coil shoved right up against the 6800uf secondary filter caps, and the heatsink unfolds right overtop of the whole thing - with no good ventilation, it just acts like an oven and cooks everything in there.
