The Seasonic PRIME 1200W 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.
The large fan is hidden behind the black grill, with the PRIME logo in the center. If you pay close attention you can see the ‘n' shaped black grill which can be removed to fit a shiny silver panel – for the Titanium units.
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.
Exactly the same modular connector layout as the 1000 Watt unit we reviewed last week. 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).

This 1200W power supply can deliver a very potent 100A via the +12V rail. Plenty of power on hand for a powerful SLI and Crossfire configuration. The 1000W model from the same family we reviewed last week could deliver 83A via the +12V rail.
