5 out of 5 eggspfft its a seasonic

Pros: Seasonic quality and reputation. decent efficiency, pretty quite for a 80mm fan.

Cons: none

Other Thoughts: this is the second one I've ordered. works great, so did the last one but...I've been a diehard seasonic fan boy for many years now ever since the first I never used anything else and never received less than the highest quality psu. but the last one of these i ordered the 12v ran at 11.81 instead of 12.04 or so like it should. I was within the wattage but think i may have exceeded ampage. that being said this model is several several years old and has a little lower amps than a newer model

5 out of 5 eggsGreat PSU

Pros: Great PSU as most people already know. Rock solid and all that was needed.

Cons: The cables are a little short so if you have a big case, you might need cable extenders.

Other Thoughts: Just buy it already!

5 out of 5 eggsGood, quiet PSU

Pros: Quiet, well built, good price.

Cons: None.

Other Thoughts: SeaSonic is generally my go-to brand for good quality, quiet and efficient power supplies. I've bought lots of them and rarely seen one fail.

3 out of 5 eggsMissing a few parts...

Pros: Well, it arrived. I can't tell you much more than that, because...

Cons: ...it arrived in bubblewrap (not in a nice drawstring bag and box like my last PSU from Seasonic, though to be fair this is OEM), and WITHOUT an A/C cord. Seriously, it's not like I have tons of those things lying around, could you maybe put that as the first line in the description next time?

4 out of 5 eggsShort connectors..

Pros: SeaSonic makes great power supplies. Fan was quiet.

Cons: Short wires. In a small case with the power supply on the bottom the wires will barely, and I mean barely, reach. I knew this when ordering but when connecting the CPU power I had to cut the wire tie to get the extra length to feel comfortable.

Other Thoughts: Be careful if buying for a case where the power supply is mounted on the bottom.

4 out of 5 eggsNot quiet

Pros: Seasonic is a top brand in power supplies. Even though this is an OEM unit with a 3 year warranty, I have no concerns about its quality.

Cons: LOUD. Loud is relative, but the fan they have in here is a cheap dual ball bearing 80mm that spins at at least 2000RPM.

The noise is quite noticeable. That quite as in very, not quite as in quiet misspelled.

If you want something quiet, the 120mm fan version might be better (my chassis is designed for the 80mm type, otherwise...) or something more expensive.

Other Thoughts: I ended up spending $15 on a Noctua fan to replace the included one. Altogether I probably could have just gotten a bigger, quieter PSU for the same price.

4 out of 5 eggsGood PSU

Pros: Nice in general. Very silent, can't hear anything. Super stable voltages.

Cons: Motherboard power cables are indeed a little short. Just 2-4 extra inches of length would make it perfect, otherwise, it's difficult to make sure it will work for your particular system. I did took into consideration the info posted by some reviewers, measured required, for my system, lenght of power cables, and only then bought this unit. It worked for me.

Other Thoughts: Good choice for Ivy/Sandy builts w/o dedicated draphics cards and limited number of drives. Assuming you know that poer cable length of 12" will work for you, a great choice for 300W PSU. Taking one egg off for obvious Seasonic mistake to make cables a bit longer, which actually decreases the otherwise strong competative edge this PUS has over competion.
