Great while it lasted

Pros: Platinum efficiency, other marketing jargon. Nice and quiet

Cons: none until it died suddenly after turning PC off

Other Thoughts: Died after 3 years. I just had to put my even older antec EA-650 in this PC (6700k/GTX 1070) that is still running strong. I bought that PSU over 7 years ago too.

Running great four years later

Pros: Got this for a great price, and its performed extremely well. Moved it into an older 1336 system that could peak draw 600W and its handled it fine. Fan barely runs.

Cons: Cables are all right angle so it can't easily fit any drives directly against a panel.

Quiet

Pros: Very quiet, even when fan kicks on, which has only happened during stress testing. Good quality cables.

Cons: CPU cable was a bit short, and barely reached across my ATX board.

Other Thoughts: SATA cables were tough to fit on the SSD-specific 2.5" brackets behind my motherboard, but someone probably makes a cable that would lay flat and work better.

Great Brand and Plat Rating

Pros: -Seasonic Brand
-Fully Modular
-Reliable PSU
-Nicely Packaged
-PLAT Rating

Cons: None at the moment

Other Thoughts: Got this PSU on sale for frond 80$ after rebate. Crazy good deal for a fully modular sea sonic plat PSU. You want a PSU to last you awhile and i'm confident this one will.

Failed after 5 months

Pros: - quiet
- modular

Cons: - failed within 5 months, tested with a PSU tester as dead
- SeaSonic RMA support is very poor

Other Thoughts: SeaSonic USA has a RMA department that goes to voicemail. That mailbox is full. This is not acceptable for a premium-priced piece of hardware.
Given the RMA difficulties other reviewers have had, I would recommend being careful before buying a SeaSonic product.
Buyer beware.

4 Years and still no problems

Pros: - Seasonic quality
- Fully modular

Cons: - None

Other Thoughts: I've had this PSU for 4 years and haven't had any issues. No noise whatsoever and if the fan has ever come on (I use hybrid mode) I've never heard it. Definitely recommend it.
