Super quiet in hybrid mode. I set up the case with positive pressure and the fan opening into the case. This might be causing air to flow through the PSU already (Note: the fan acts as an intake into the PSU and Seasonic recommends having the opening into the case for hybrid mode or drawing cool air for always-on mode).The modular cables are awesome. I could just plug in the few that I needed and it made routing them out of the way even easier.Overall build quality feels very solid and so far (a week in) everything is working great.

Used in a computer build for a client. This is my sixth Seasonic PSU - four for client builds, one for myself, and this most recent purchase - and none of them have given me any issues since install, all running for one or two years. Nearly silent, high quality construction (at least, on the outside - I have yet to open one), braided cables are great. Honestly, I've had some infuriating case builds, and these cables, while firm, bend securely and I have no concerns on them fraying, breaking, splitting, or otherwise. I'm in love with Seasonic units, and have no plans to use anything otherwise.If I may inject some personal opinion, this unit comes with "10 year warranty" plastered on the box. I can't find a single other company to warranty for that incredibly long. To me, a company that gives that long of a warranty has deep faith in their parts.

Compering to my other Platinum PSU, there are no faults that I can find with this unit. I have this installed in a Fractal Design Define C case on the bottom. I do not hear any noticeable noise from this unit.I only buy Platinum PSU for two reasons. First reason is due to better power efficiency that comes from better components and system power swings. The other reason, and maybe even the main reason, is my expectation that Platinum rated PSU units built with better components will live longer and reduce the risk of catastrophic PSU failure.The only trick is not loosing those extra cables that I did not use, thankfully the unit comes with a bag.
