We like the appearance of the PRIME power supplies, and they are finished to a high standard. The Platinum units do not have the same shiny silver grill that is showcased on the Titanium models, so they are easy enough to tell apart.
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 easily removed to fit a shiny panel – for the Titanium units.
This side of the unit is home to the power socket, power switch and Hybrid fan switch.
This Hybrid mode allows 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 1200 Watt and 1000 Watt units we reviewed in previous weeks. 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).
Exactly the same modular connector layout as the 1000 Watt unit we reviewed last week.
