[USER=272]@Supercluster[/USER] made very good points at choosing a 12V PSU.


An additional opinion is that the hold-up time doesn't really affect us the same way regular PSU does.


The hold up time is considered after the loss of the power good signal. That is, the PSU should detect the loss of power, cut the power good signal, and then from there the pc complete the operation and prepare for emergency power loss.


The other thing is the hold up time was a requirement developed during a time of slow pcs and even slower disks.


I can't say how much it affects us 12V builders but it does affect us differently. The pc doesn't really see power good signal with a plug in unit.
