This review is from: SeaSonic M12II 750 SS-750AM2 750W ATX12V / EPS12V SLI Ready 80 PLUS BRONZE Certified Modular Active PFC Full-modular Power Supply New 4th Gen CPU Certified Haswell Ready
Pros: Excellent modular cable setup
Cons: Absolutely terrible fan - loud at idle and even louder at load
Other Thoughts: As another review(s) stated below, the fan on this thing is terrible! It was a big disappointment, as I had the computer all assembled and tidied up, with cable ties, etc., only to discover that the computer was unusable due to the fan noise! I could hear it across the house, in a separate room. It was loud at idle, then got even louder under load. I initially was confused what the source of the noise was, thinking it was the two GTX 780s or case fans, but low-and-behold it was this seasonic 750W PSU. The PSU was bottom mounted in a NZXT case, with plenty of gap between floor and PSU fan intake.
It was a shame, as I was really happy and impressed with the cabling. I had just what I needed, with room for growth. I will say that this was one of the best modular PSUs I have dealt with, in terms of cable selection, length, options, etc. Hopefully the RMA replacement or repaired unit works out, as it was a joy to work with the setup.
Oh, and regarding the RMA and tech-support. You just get an answering machine all day for their tech support, asking to send an email. I submit an RMA, and the approve it right away. So I am sending it back, though I would have like to discuss it with an engineer first. Oh well.

Pros: Seasonic is one of the very few honest to gosh actual manufacturer of PSUs, Has 5 yr warranty. My last one lasted 5 years and a few months. It is highly regulated and protects my PC from power surges and irregularities.
Cons: none
Other Thoughts: why buy the products of fabless rebadging companies like Corsair when you can get the genuine article straight from the manufacturer? I bought a Corsair and had to return it because it wouldn't run my old AGP graphics card!

Pros: Modular, fair price, steady power output. Easy to install and worked great for a year
Cons: I bought this on 4/4/2013, It died on 8/13/2014. First PSU to ever die on me like this. I researched a lot and every source was saying Seasonic was the best. Well I'm replacing it with a Rosewill now. I will not buy another Seasonic PSU. It should have lasted longer than 15 months.

This review is from: SeaSonic M12II 750 SS-750AM2 750W ATX12V / EPS12V SLI Ready 80 PLUS BRONZE Certified Modular Active PFC Full-modular Power Supply New 4th Gen CPU Certified Haswell Ready
Pros: Underrated (can do about 750W on 12V alone), fully modular with flat black cables, high quality, plenty of cables included.
Cons: Much louder than it should be. It is the loudest part of my system at idle, audible even with headphones on.
Maybe the fan is defective? I don't know. The air it is pushing out isn't even warm, so I don't see why the fan is being so loud.
Other Thoughts: Its a shame this unit has such good test results but is stuck with a terrible fan.
Another thing to note: You can get an XFX P1-750B-BEFX for almost as much as this, which is the exact same as the Seasonic X-Series, which has a fan that turns off and is Gold rated.
Manufacturer Response:
Hi Rodney, Very sorry for your experience with our power supply. I recommend that you RMA the unit so it can be tested to make sure the fan control is operating correctly. Thank you.

Pros: I was pleasantly surprised to get the new EVO edition of the Seasonic M12II. Fully modular. I read the Eggxpert Tier list and few others. Reading lots of psu's made with Seasonic parts, why not go with their psu. Buy it for sure.
Cons: As been stated in previous reviews. The modular cables are pain to get bent right and into motherboard slots. But no egg reduction for that. Like the brand new cables and freshly new smell.
