Seasonic PRIME 1000W Platinum PSU Review

The Seasonic PRIME 1000W Platinum supply is a great looking power supply, but regular readers will notice that the fan grill section is missing the accented silver section which you can see HERE. The Titanium supply is therefore a little more dynamic looking.

You can see the ‘outline’ close up actually of where the silver/chrome section would be fitted if this was a Titanium rated unit.

One side of the unit is home to a big cooling vent, with a power connector and switch at the side.

There is also a switch for Hybrid mode – allowing the fan to be disabled completely when the unit drops to a specific temperature threshold. Seasonic claim the Hybrid Fanless mode works up to:

  • Approximately 50 % (±5 %) of system load at 25 °C.
  • Approximately 30 % (±5 %) of system load at 40 °C.

One side of the Prime Platinum is home to all the modular cabling connectors. The main M/B connectors are indicated along the bottom of the panel – clearly labelled. The Peripheral/SATA/Molex connectors are visible in a bank of two and three along the top right side. On the other side are all the CPU and PCI-e connectors in a row of 1, 3 and 2 from top to bottom (6 in total).

Above we can see the specifications of the power supply. The Model number is SSR-1000PD Active PFC F3
