Product Overview The Seasonic S12II series needs no introduction, as this is a well-established, long-standing Seasonic series that has withstood the test of times. The S12II Bronze Series achieves the 80 PLUS® Bronze standard of providing at least 85 % power usage efficiency at 50 % operating load. This efficiency combined with active power factor correction enables this power supply to lessen energy waste. The S12II-620 features all-in-one DC cabling design and comes equipped with additional EPS connectors to support both 6-pin and 8-pin PCIe connectors for the most current high-end dual graphic cards. It is a reliable power supply backed with 5 years of warranty. 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.

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.

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

Gold Plated Connectors
Gold plating critical connector pins (motherboard, CPU and PCIe cables) extends the lifetime of the connectors and greatly increases the efficiency of current transmission.

Ample +12 V Output
Enhanced +12 V current capability broadens utilization possibilities.

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.

620W Seasonic S12II-620 SS-620GB Wires 80PLUS Bronze, 1x120mm Fan, ATX, PSU is rated 3.6 out of 5 by 5.
Rated 1 out of 5 by from Bad company and product I ordered this product, expecting it to work, however when it arrived there was a fault where it didn't work at all even after carrying out the paperclip solution. I emailed them about what I should do and they replied saying to send it back in which I did, although they didn't tell me it was going to cost me £13 out of my own pocket as they don't reimburse you for delivery charges although it's their fault in the first place for sending faulty goods to customers without testing them. I wouldn't recommend this product or even this company. If you do decide to order from this shambles of a company then be prepared to pay the price of deliveries. This was my first time ordering from this company and I can happily say I will not be doing so ever again.

Rated 5 out of 5 by from Seasonic 620W Comprehensive PSU kit I bought this to replace a flaky and unreliable ACE 750W PSU which was causing boot up and general instability problems. Ordered on Saturday fitted Sunday morning. Computer now totally stable again. Comprehensive product with all required cables, cable ties and screws.Perfect! No more cheap power supplies for me!

Rated 5 out of 5 by from Excellent quality and best value for money PSU Bought this PSU as it's a Tier II supply as suggested by Tom's Hardware, after my old PSU packed in. Very good quality, more than capable of supporting an Asus GTX 1060 and a large amount of peripherals and runs very quietly. Highly recommended PSU.

Rated 5 out of 5 by from Quiet, comes with plenty of cables. Excellent bang for buck This power supply (like all Seasonic units) is built with high quality components such as Nippon Chemi-Con and Rubycon capacitors. The fan is very quiet even under load, which is a must for silence freaks like me. It comes with plenty of cables for additional hard drives and even 4-pin molex connectors for old style fans. The non modular design makes for more difficult cable management, so make sure the case you use for this has a shroud over the power supply area if you care about tidiness. You probably won't find another power supply with high quality components at this price point.
