Special Features

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 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).

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.

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

Pros: - Excellent performance and efficiency (92% @ 50% power load @ 50C) - Compact size for a 1200W power supply unit - Hybrid fan function allows for silent operation when using 300W or less - A lot of cabling options for even the most extreme computer builds - Seasonic's 7 year warranty!
Cons: - Fan operation can be a bit louder as it spins up to keep the power supply cool when at 70% or higher load (~840W) - Pricing varies from e-tailer to e-tailer...make sure to get it on sale! Don't pay full retail for it if you can wait. - No monitoring software available like Corsair's Command Link :(
Overall Review: The Seasonic SS-1200XP3 is an oustanding power supply. DO NOT LISTEN TO THOSE NON-TECH SAVVY BUYERS WHO POSTED BAD REVIEWS ABOUT THIS POWER SUPPLY! Johnny Guru gave it a 9.8 out of 10! There is nothing more to be said. This power supply delivers as promised! The unit came well packaged and included all the necessary cabling or accessories. Also included is a nice velcrow bag to keep all the extra cabling that you may not use after building your system. I am currently using the Seasonic SS-1200XP3 to power my main gaming rig: Intel Core i7 3930K @ 4.5Ghz @ 1.35V Asus Rampage Extreme IV motherboard 32GB 1600Mhz Crucial Ballistix Tracer DDR3 (8 x 4GB) 3 x Gigabyte GTX780 GHz Edition cards in 3-way SLI 2 x Corsair Neutron GTX 480GB SSDs in RAID 0 2 x Hitachi 3TB HDDs (storage) 2 x LG Blu ray burner optic drivers Asus Xonar D2X sound card 5 x 120mm Corsair SP120 fans 1 x 140mm Corsair SP 120 fan Custom liquid cooling (Swiftech MCP655 water pump) The recommended power supply for my setup according to the eXtreme power supply calculator is ~1200W. The Seasonic SS-1200XP3 does NOT disappoint and performs perfectly without one hickup or instability issues whatsoever. I'm gaming at high overclocks on both my CPU and three GPUs (116% overclock) at 4K resolutions in Crysis 3 and BF4. Everything runs rock stable for hours on end. For this price point, the Seasonic SS-1200XP3 is the perfect choice to power your gaming rig that can't be beat!
