Well, I've either done something horribly wrong...

...or installing a new power supply unit into a PC is actually a piece of piss.

You know, even though this is meant to be a 'silent' PSU, I'm glad to hear the fan purring quietly away.

It means the damn thing's actually moving, unlike my old PSU, whose fan died at some indeterminate point in the past, hence the frequent overheating and crashing during high-resource games and prolonged periods of idleness, even when I removed the side panels to ease airflow.

And I'm pretty sure it's quieter than the near-buzzing of the old fan (and that's before I replace the side panels, too).
