Frequently Bought Together
Product Overview In addition to being highly efficient, the S12II Bronze Series maintains important features such as the stable and proven Double Forward Converter circuit design for reliable power conversion. Sea Sonic’s industry leading Smart and Silent Fan Control (S2FC) achieves not only reduced operating noise but by lessening the number of fan rotations it also incurs savings on the costs of energy for its users. The use of low resistance and high temperature rated Japanese brand capacitors only adds to the reliability of this unit, which will surely keep the power flowing when needed. Features 80 PLUS® Bronze
The 80 PLUS® Bronze certification indicates that a high percentage of the electricity is converted into useful power, therefore there is less heat lost and more money saved on the electricity bill. The 80 PLUS® Bronze certification guarantees greater than 82 %, 85 % and 82 % efficiency at 20 %, 50 % and 100 % operating loads, respectively. Sea Sonic’s Bronze Series is an economical choice with great performance and high built-in value.

Fluid Dyanamic Fan Bearing
High performance Fluid Dynamic Bearing (FDB) fans are designed to take advantage of the impact absorbance effects of oil. They are extremely reliable and generate considerably less operating noise and heat than ball bearing fans. The lubrication of the bearing surface reduces friction and vibration and therefore lowers overall power consumption. Due to the effortless, quieter rotations and its robust construction, this reliable fan technology also greatly increases the lifespan of the fan.

How it works
When the fan shaft rotates, high pressure oil drifts along the grooves of the bearing sleeve to generate a thin layer of lubrication between the bearing faces. As the speed increases, so does dynamic oil pressure and the shaft is lifted from the bearing to create smooth, effortless rotations. The herringbone shape of the groves helps to efficiently channel the lubricant and avert leakage.

S2FC
The intelligent thermal circuit feature is designed to find the optimal balance between the necessity to cool the components and the need to run the power supply in the most silent manner possible.

Universal AC Input
Switch-mode power supplies can tolerate a wide range of power frequencies and voltages. The power supply is designed to automatically adjust to the inpout AC voltage, therefore it can safely be used anywhere in the world.

Easy-swap Connectors
The markings on the connectors minimize the possibility of mistakes and facilitate installation.

Reviews
520W Seasonic S12II-520 Bronze Series, 80PLUS Bronze, Dual Rail 20A, 1x120mm Silent Fan, Fully Wired, ATX PSU is rated 5.0 out of 5 by 6.
Rated 5 out of 5 by from Perfect Value For Money This power supply cannot be matched on Amazon even for value. I recently built a new AMD based PC to replace my old Quad Core setup inside a good size tower case. The set up consisted of; AMD Ryzen 5 1600 CPU Asus B350 Plus Motherboard 16GB Corsair DDR4 300MHz Ram Zotac GeForce GTX 1060 6GB Ram The old power supply I had worked but was resulting in random crashes as it was simply not up to spec to feed this new set up with the juice it needed. It's great value for money and will fix any crashing problems you could be randomly getting when gaming with this GFX card.

Rated 5 out of 5 by from Awesome PSU Firstly it's built by Seasonic so you are purchasing quality. Its not flashy or lit up like a Christmas tree but will power your system with efficiency and its very quiet. Secondly if you do your research on computer components you will see Seasonic are in the top 3 manufacturers of PSU for quality, reliability and value. I cant recommend this PSU enough, has rave reviews and does exactly what its made to do without a fuss and showing off with flashing LED's.

Rated 5 out of 5 by from Great quality product for the money! This PSU is seriously good value for money, where other PSU's try to lure you with Gold ratings and more watts, this one just focuses on quality. Great buy if you're looking for a cheap and HQ PSU.

Rated 5 out of 5 by from Happy customer I had taken my time in making this purchase and reviewed other comparable 500W+ PSU's. Excellent choice imo. Product delivered on time, maybe a few too many email updates, but accepted that as excellent customer service. Well packeged etc.

Rated 5 out of 5 by from As you'd expect from SeaSonic There really isn't much to say about a power supply of this price range, except that its the quality that you would expect from a Seasonic made unit. Would recommend.
