Returned due to buzzingI've been using Seasonic PSU's for years and have always found them superb. Another rig has a Seasonic 650W X-Series which is the forerunner of this Platinum. However I had to send this PSU back as it made a pronounced buzzing noise.
This doesn't mean it was defective as such - sometimes you get unlucky with PSU's. I was building a super quiet watercooled rig so the buzzing was too much for me.
To replace it I bought a Corsair AX760. These are rebadged Seasonic Platinums so you see I still have confidence in the brand. I already have an AX860 in one rig and that PSU is flawless as is this one.
Things I like about this Platinum and AX ranges are firstly they are fully modular so there are no redundant cables to hide and secondly they are hybrids. This is particularly useful for a quiet build as in hybrid mode the PSU fan only spins up if it exceeds about 50% load. Below that they are entirely passively cooled.
Hope this helps

A premium quality power supplyThis Seasonic power supply has worked faultlessly since installed. It comes with lots of different cables as well as velcro loops and cable ties to aid installation. Fan noise is not noticeable compared to the other fans in my case. A bit expensive but you get a top quality product.

Seriously quietCan't hear this supply when it's running. In hybrid mode the fan barely comes on. This is running i7 processor, GTX 770, a couple of SSDs, five 120mm case fans and a beQuiet dark rock pro cooler.
Cables could be more flexible though.
