Seasonic Platinum 1000W Modular Power Supply Review

Rating: 9.0.

Seasonic are one of the most famous and highly regarded power supply manufacturers. They create many high grade units for other companies, allowing them to rebadge their designs. Today we are reviewing one of their most powerful products under the ‘Seasonic’ brand, the Platinum 1000W.

The Seasonic Platinum 1000W is (not surprisingly) 80 Plus Platinum certified, aiming to target the efficiency sensitive audience. It is a fully modular unit featuring a LLC/full bridge circuit topology with a unique integrated DC connector panel with an embedded voltage regulator module.

One of the talking points of this unit is the new ‘Hybrid’ Silent Fan Control which offers a three phased (Fanless, Silent and Cooling Mode) thermal control to balance the noise levels between cooling efficiency. The company also offer a selector switch which is provided to allow the user to control the settings.

    If only the very best is good enough for you, then look no further than Seasonic

    When it comes to power supply. You have very good power supply and then you have Seasonic power supply. I own a X560 Gold unit powering a 2500K @ 4.7Ghz and a GTX670 @ 1.25GHz (turbo). The X560 have been tested up to 750W before failing! Over engineered you say? LOL… So a puny CPU / GPU overclock is nothing even for a lowly 560W unit. Even under load, the fan barely starts . It’s totally silent 99% of the time!
