Special Features

SeaSonic Power Supply

Ultra Tight Voltage Regulation
Improved load voltage regulation keeps the voltage fluctuations on the 12V output within +2% and 0% (no negative tolerance), and on the 3.3V and 5V outputs between +1% and -1%, which (under 80 PLUS load conditions) results in smooth and stable operation.



SeaSonic Power Supply

Seasonic Hybrid Silent Fan Control - S²FC & S³FC *
The industry first, advanced three-phased thermal control balances between silence and cooling. The Hybrid Silent Fan Control provides three operational stages: Fanless, Silent, and Cooling Mode. In addition, there is a switch provided to allow for manual selection between the Seasonic S²FC (fan control without Fanless Mode) and the S³FC (fan control including Fanless Mode).




SeaSonic Power Supply

Benefits:

  • Reduces noise without increasing temperature.
  • Extends fan life by eliminating unnecessary rotation.
  • Optimizes heat dissipation at all times.
  • Fanless Mode provides unsurpassed silent performance.

New Feature: Hysteresis is achieved by a fan control IC, which optimizes how frequently the fan switches on and off. At 25 °C ambient temperature the fan turns on when the load rises above 35% (± 5%) and it turns off when the load drops below 25% (± 5%). Due to this lag in response the fan switches on and off less frequently, which reduces power loss in Fanless and Silent Mode.



SeaSonic Power Supply

Dual Copper Bars
These pure copper bars conduct high current more efficiently to reduce impedance and minimize voltage drop.

Pros: I had a 750w before but wasn't enough for two 980ti overclocked, it would crash. So I bought this and it solved the problem.

Cons: nothin yet

Reliable PSU but fan is too loud

Pros: Great Build Quality. Comes with nice braided cables that are long enough to use in a full tower case. The hybrid mode is nice for silent operation

Cons: When the fan comes on it is very loud. It also randomly comes on and stays on for an unnecessary amount of time. For example when I'm browsing the web it will just start up even if I'm drawing a lot of power for my video card or other devices.

Overall Review: I sent Seasonic an email about the fan issue but I have not received a reply. I would not expect Seasonic to release their high end PSU with this problem.

5/ 5

Pros: seems like a reliable PSU. worked the first time. my system seems more stable now and starts up faster. I would recommend this to anyone who has a rig with lots of extras, like expansion cards and drives.

Cons: none

Overall Review: I purchased this because I was using and older 1000W PSU and having some very strange issues with my computer (crashing, long startup times, etc.). decided on seasonic because I have used their PSU's before on smaller builds and was always satisfied with their quality.

Seasonic 1200 Platinum XP3

Pros: One of the best power supplies on the market. Seasonic is the OEM manufacturer for Corsair, EVGA and many other top rated power supplies and this same quality is apparent in this unit. Rock-solid stable power delivery even under high load.

Cons: None.

Nice Unit with a MAJOR Nuisance

Pros: Stable, quiet, good reviews by power supply reviewers.

Cons: The first unit came dented, the second unit came with a very, very slight sent on the same side on the same side. The power cable between the outlet and power supply unit is too loose and the slightest movement will shut off your system. If you do not get the cable fitted 100% into the power supply unit, it won't power on. (You'll find yourself wiggling the cable to get the right fit/spot so your computer can turn on.)

Overall Review: I needed to apply the right amount of electrical tape to allow the cable to fit into the power supply without being loose. If you periodically need to unplug and re-plug your cable (for moving the case or cleaning inside the case) this will be a major nuisance because you will need to periodically change that electrical tape. You will find that you need to keep cutting the tape on the end of the cable (the end that goes into the power supply unit) to find the right thickness so that it can actually fit into the power supply's socket while not being loose.

Manufacturer Response:
Hi, Thank you for your review. Please note, the AC Plug must be pushed into the AC Inlet firmly and yes, there might be a slight wiggle but it will be secure and not affect the running of the system. As well, please use the AC cord that is supplied iwth the PSU. As for the dent, I apologize for this and I kindly ask that you take a photo and please send it to newegg@seasonicus.com along with any questions or comments you may have. Thank you.

Pretty good

Pros: Silent fan, and runs 2 980's like a champ. I've never noticed the fan come on in Hybrid mode, even while gaming. Granted, I don't really check out my PSU fan that often.

Cons: Outside of the first one being DOA, none that I can think of.

Overall Review: First one was DOA. The RMA process was pretty straight forward, and only took a while because I dragged my feet. It arrived in their facility on a Thursday and I had a new unit shipped out by Friday.
