Seasonic have opted for a Ong Hua 120mm fan, Model number HA1225H12F-Z. This is a high grade Fluid Dynamic Bearing (FDB) fan designed for low noise emissions.

These fans not only tend to emit lower noise levels, but they are rated to last longer as well due to the lubrication of the bearing itself.

The Seasonic XP3 design is rock solid and this isn't the first time we have looked at it. It also featured in the Cooler Master V1200 Platinum power supply which we reviewed earlier this year. Soldering quality is excellent throughout.

Behind the AC receptable is a sealed PCB which is home to some of the components of the EMI filter – a single X cap, four Y caps and a CM choke. The other components of the filtering stage are on the main PCB, which include an MOV, two pairs of Y and X Caps and two more CM chokes.

The primary side is a full bridge design with an LLC converter for lossless switching. The secondary side uses a synchronous design with +12V fets on the main PCB. The DC-DC converters are installed on the modular PCB to help reduce power loss.

The main PCB and modular PCB incorporate high grade Japanese electrolytic and solid capacitors.

Seasonic are using three high grade Japanese capacitors on the primary stage (class leading ‘Nippon Chemi Con’). These are all 105c rated. All three are rated 330uF 420V. The Seasonic Platinum 1200W unit uses three more powerful 390uF rated capacitors in the primary stage, for those interested.
