The Seasonic PRIME 850W GOLD supply is an almost identical design to the Platinum versions with gold accenting on the case. The Platinum version is more of a chrome colour scheme.
The PRIME logo on the Gold rated power supply is different to the other ranges – again it is coloured gold. No N shaped grill on this power supply either, with Seasonic opting for plain black.
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 Gold unit is home to all the modular cables. The main M/B connectors are indicated along the bottom of the panel and are 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 is exactly the same layout as the higher capacity 1000 watt PRIME Gold power supply that we reviewed a couple of weeks ago.
Above we can see the specifications of the power supply. The Model number is SSR-850GD Active PFC F3.
