2 out of 5 eggsPoor connectors

Pros: They run cool, and the voltage is well regulated, but see below for issues under 'Cons'.

Cons: This power supply came with poorly manufactured SATA power connectors which were virtually impossible to attach to components. In fact someone who works for me partially broke the power connector on a new SSD in attempting to connect it. This represents very poor quality control and whereas we used to buy many Seasonic power supplies we will no longer utilize them.

5 out of 5 eggsGreat!

Pros: Great retail packaging. Plenty of cords. Modular. Rebate. Quiet.

Cons: None so far.

Other Thoughts: For the first time I didn't buy the least expensive unit for my power needs and I'm glad I did. This unit seems like a great value. I installed this in a Cooler Master HAF X (huge case). The cables were all long enough to route behind the motherbaord tray for a nice clean look. I mounted it upside down to exhaust out the bottom of the case.

5 out of 5 eggsGood PSU

Pros: Greats PSU. I love how it is completely modular. In my opinion every PSU needs to be this way it makes hiding wires easy because u only use what is needed and makes for a cleaner looking pc. Stable power.

Cons: None looks and runs great

5 out of 5 eggsAMAZING!

Pros: AMAZING! It's THE most beautiful PSU out there! I love how it was boxed, with the velvet (fake velvet), and the little bag for the cords, much better than just a box with plastic wrap. Also it runs smoothly with a great little button for hybrid and normal. I love it

Cons: none

1 out of 5 eggsPSU Failed after 4onths

Pros: Great performing PSU.

Cons: The unit popped and smoked in a flash.This literately exploded. I have never had this happen to me with any other PSU and I have built a large number of custom PCs in the past.

Thankfully my components remain intact but I think my boot drive is gone. Will have to reformat to make sure. Its under warrantly so I hope I will have a smooth replacement process.

1 out of 5 eggsGreat deception

Pros: Cable management as expected

Cons: Noisy fan - it is the loudest component in my rig. Hybrid mode does not work! I have a total power consumption of 101 W, less than 10% of nominal rating and still it seems the fan is operating at full speed! Tried switching the fan control mode with PSU on and off and nothing seemed to happen.

I ONLY bought this power supply because of the advertised fanless mode operation below 20%+-5% load and it's not happening so since I live overseas I just threw 220 USD in the garbage.

CPU temp: 19 C
GPU temp: 32 C
room temp: 15 C

Tried removing the fan from the case and setting it with the fan outlet upwards in order to allow natural convection to remove hot air from the PSU. Fan kept working and the air was flowing at room temp.

Other Thoughts: Ridiculously bad costumer technical support, it seemed like I was speaking to a non interested and low knowledge person, at the end they asked me to fill out the RMA form. Well, guess what, I live overseas and it's going to cost me another 220 USD in shipping and duties on the way back so thank you Seasonic for fake advertising / bogus quality control. Will defenitely not buy another one again and will recommend the same to my friends / coworkers.

5 out of 5 eggsBest power supply I've owned

Pros: This has been an excellent power supply. I have had it for 4 months now and it has run flawlessly. System:
ASUS Crosshair V Formula MB
AMD FX-8120 Zambezi 3.1GHz
CORSAIR Vengeance 16GB (4 x 4GB)
Phanteks PH-TC14PE_RD 140mm CPU Cooler
Nvidia GeForce GTX 460 x2 (SLI)
Blue-ray combo, DVD, etc.

It was wonderful having a fully modular unit so that I only had cables I needed in the case. There are plenty of cables for all your needs, so rarely if ever should you need to request or buy additional cables. The fan is quiet so I'm super happy about that as well. Additional comfort from the SLI certification since I use SLI and from the 80 PLUS Gold (which basically guarantees no less than 80% of maximum power rating at any time).

Cons: None so far.

Other Thoughts: It comes with a beautiful though fairly useless velvet bag that the unit was in, a much more usefull cables bag with two spacious compartments, and a half dozen sweet cable ties - the really nice micro velcro kind.

5 out of 5 eggsAs good as Corsair!

Pros: I've been building rigs for years, and have always been a Corsair guy (for gaming machines). I wound up doing a server build for a customer and they already had a Seasonic. Noticed really solid voltages during stress testing, so gambled on this guy. Top notch! Reviews don't lie! Under full load (Metro 2033 at full clip using two Radeon 7850s in crossfire and i7-970 doing ffmpeg conversion in the background), the 12V never hovered above 12.025, 3.3V never above 3.31, and 5V never left 5.0! Was inaudbile during this test (as the CPU fan really was the loudest). Very impressed! Packaging and fit and finish is outstanding.

Cons: Cables not very flexible. That's reaching, I really got nothin'

Other Thoughts: Have always been a Corsair guy, but now adding Seasonic to that pedestal.

5 out of 5 eggsGreat PSU so far

Pros: This power supply is powerful, efficient, and quiet. This is a very well-constructed unit, with high quality parts. I love the fully modular design. Only time will tell whether the quality will hold up, but so far so good.

Cons: I would have liked a couple more molex cables in the bundle.
