Seasonic Platinum 1050W Modular Power Supply Review

Introduction & Packaging

Seasonic is one of the most respected PSU manufacturers in the world, not only do they create their own premium grade units, but they’re also one of the most popular manufacturers used by a range of PSU brands around the world. Time and time again we’ve seen them deliver flawless designs, incredible performance and a whole lot more, so we’re very excited to have one of their latest and greatest units on our test bench today.

The Seasonic 1050W packs a huge amount of power, making it an ideal choice for overclockers and those with multiple graphics cards in their systems. It comes with premium grade components throughout and this helps it operate at 80 Plus Platinum efficiency, meaning it’ll cost you less on your electricity bill to run vs Gold, Bronze and below rated PSU units.

Packed with features such as Ultra Stable Voltage, a Hybrid Silent Fan Control which allows for 0RPM operation at low loads and Dual Copper Bars, the 1050W Platinum sounds like a premium choice for system builders.

As you can see, the 1050W hits all the usual requirements of a modern PSU, can operate between 100-240v AC and features all the protection features you would expect.

The packaging is nicely designed, keeping in theme with the rest of the Seasonic range.

Around the back, a quick run down of what 80 Plus Platinum efficiency is, as well as a run down of the major features; which we’ll take a look at in a moment.

In the box, you’ll find a durable storage bag that houses all the modular PSU cables and the 3-pin power cable.

There’s also an assortment of plastic and velcro cable ties to aid with cable management, an owners manual and with this unit, a UK 3-pin power cable.
