Seasonic XP2 Platinum 660W Power Supply Review

Introduction & Packaging

Seasonic is one of the most established names in the power supply industry, not only do they make many of their own very high quality products, they’re also an industry leader for manufacturing high-end PSUs which are used and sold by a whole host of other brands; there’s a good chance you own a Seasonic PSU and don’t even know it. Seasonic products have proven to be award winners many times before, not only from us here at eTeknix, but in reviews all around the world. The unit we have today is a mid-range 660W unit, so I’m not expecting earth-shattering performance, but it does have a few features that are worth getting excited about.

The SS-660XP Active PFC F3 PSU comes with an 80 Plus Platinum efficiency, which should make it very cost-effective to run in your system. It also comes with a powerful +12V single rail design, an active/hybrid fan design and fully modular cables.

The packaging is nice and simple, with a stylish image of the PSU on the front, and some small branding for the 80 Plus Platinum efficiency, Haswell Ready and the 660W power rating.

Around the back, you’ll find a quick explanation of what 80 Plus Platinum means, as well as some details on the hybrid fan mode, which we’ll take a closer look at in a moment.

Inside the box, another box! Although this one houses all the additional cables for the PSU.

There’s also a mains power cable, owner’s manual, velcro cables ties, plastic pull-cable ties, four PSU screws and a small “Powered by Seasonic” sticker.
