Seasonic Platinum 1000W Modular Power Supply Review

Review Score:
54 Flares 54 Flares ×

We love the appearance of this unit, it is black and silver (almost gunmetal). The name of the product is on the side panels. It measures 190mm x 150 mm x 86 mm (LxWxH).

The supply is vented on the front, alongside a power button and connector.

The dual black/silver tone top looks great. Seasonic have opted to put their logo along the bottom, rather than in the center of the fan. Another nice touch.

The modular connectors are all clearly labeled to ensure that the installation phase is not problematic. There is a blue sticker highlighting the Hybrid and Normal modes. This has to be removed before using. This review was handled in ‘normal’ mode as we want the fan active during our intensive stress testing.

Hybrid is classed as S3FC fanless silent mode and Normal is classed as S2FC silent cooling mode. S3FC is designed to turn off the fan at lower power levels and the S2FC mode keeps the fan running all the time. Normal is the best choice for the majority of environments.

The power supply can deliver 996W to the single +12V rail, or 83A. Extremely impressive figures.

    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!
