Seasonic Snow Silent Series 1050W Review
Product name: Seasonic Snow Silent Series 1050W
Seasonic, one of the most popular and high quality PSU manufacturer on the market since 1975, released end of 2014 another fully modular PSU with 80+ Platinum certification called Seasonic Snow Silent Series 1050W. This time they decided to paint it in white and call it Snow Silent. Snow = white. Silent = well let’s find out. Some Seasonic PSU we have tested before were not very silent under high loads. As there was bigger demand for silent fans, Seasonic finally offered its solution. Let’s start with quick unboxing and general overview.
As traditional by Seasonic Products, also this PSU is very nice protected in hard foam and cables are in its own bag. We find also instructions and technical information inside the package. Backside presents all main features of this PSU as well as graphs of how Hybrid Silent Fan Control works.
On the side of the package are all most important information, such as Voltage and individual power delivery specifications.
Taking the PSU out of the package was like opening a Christmas presents. White bag gives it just a little bit of luxury feeling and also some extra protection.
As we know this PSU is going to be used mostly for high-end systems there is more then enough SATA and Molex connectors, as well as 8 PCIe connectors so it will be able to power up to 4 graphics cards. We like to see the “flat” cables which are easier to work with and also very flexible.
Seasonic Snow Silent Series Cables and connectors specification:
Power supply itself looks astonishing and we really like the overall design and especially the fan grill.
Dimensions: 190 mm (L) x 150 mm (W) x 86 mm (H)
Blue sticker in front of the PSU gives you quick informations about usage of the hybrid fan control selector switch. You can select between Normal mode and Hybrid. Normal will enable the fan to rotate continuously in Silent and Cooling modes, depending on the system load. Hybrid enable the power supply to run fanless up to approx. 35% of of the maximum rated load of PSU, after that the fan starts to operate in Silent/Cooling modes.
Seasonic uses hexagonal mesh( also called honeycomb) for fan grill which is not only optically very good looking but also allows appropriate airflow and good protection for fan itself.
Snow Silent edition uses a fluid dynamic bearing fan of good quality, longer lifespan and quieter operation.
After we removed the cover, we see that even PCB is white. What a nice finish in details.
Using of Nippon Chemi-Con capacitors are guarantee of high quality as well as reliability and smooth voltage. Seasonic uses the best Japanese capacitors which are labeled at 105 °C for longer lifespan.
All heat producing components are perfectly cooled with aluminium fins. Also soldering quality on the main PCB is excellent, but we are used to see this by Seasonic products.
Simple Voltage testing.
As you can see we have measured very clean Voltage delivery, for detailed and full load test results please follow the Link at http://www.JonnyGURU.com/
