Seasonic Platinum 1000W Modular Power Supply Review

The Seasonic Platinum 1000W arrives in a box which is coloured to suit the 80 Plus Certification – in ‘Platinum'. There is a high resolution image of the product on the front, artistically presented.

The power supply is shipped protected inside sculpted foam with a user manual on top. The modular cables and accessories are shipped in a separate part of the box. The power supply is additionally protected inside a soft felt bag.

Seasonic supply the modular cables in a large, double sided pouch. They also include a case badge, branded cable ties and some screws.

This power supply is a fully (pure) modular design, so no cables are hardwired into the chassis.

Cable Connectors
MB 20+4 pin x1 (590mm)
CPU 4+4 pin x1 (650mm)
CPU 8 pin x1 (650mm)
PCI E 8 pin (6 pin +2) x2 (600mm)
SATA x9 (530mm+150mm+150mm)
SATA x2 (530mm+150mm)
MOLEX x6 (550mm+150mm+150mm)
MOLEX x2 (350mm+150mm)

All of the cables are high quality, sleeved (covered in black braided plastic mesh) and there are no shortage of PCIE cables (6+2 pin) for demanding Crossfire and SLI systems. There are a total of 11 SATA connectors, meaning this power supply is also ideal for a massive storage server system.

  1. Excellent unit. Seasonic are great, dont they make for XFX and a few others too?

  2. Absolutely fantastic design, they are the best imo for quality

  3. 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!

  4. The Platinum Series features a high-tech LLC/full-bridge circuit topology with a unique integrated DC Connector Panel with an embedded Voltage Regulator Module.
