A Detailed Look (Cont’d)
The Seasonic Snow Silent-750 comes with a good assortment of modular cables. All of the cables except the 24-pin ATX power cable are the flat, ribbon-style cables. (Note: cable lengths are listed in the Specifications box, back on page 2.)

Here are a few photos of the Seasonic Snow Silent 750W power supply showing the components and internal layout. As you can see, components are neatly laid out with good spacing for optimal airflow.
Once inside, we see the design of the Snow Silent-750 is very similar to other top-tier Seasonic power supplies. The main differences between the Snow Silent 750W and the Seasonic Platinum 760W are as follows:
• Platinum 760W has an extra 10W output (on +12V)
• Silent Snow chassis is 170mm deep vs the Platinum 760W at 160mm
• Different fans: Silent Snow-750 uses Hong Hua and Platinum 760W uses Sanyo Denki
• Hybrid Silent Fan Control uses a slightly modified profile
The Seasonic XP2S platform incorporates a modern topology that delivers tight voltage regulation, high efficiency and low AC ripple on the DC outputs. The primary side incorporates a full bridge rectifier and resonant LLC converter for zero voltage, lossless switching, while the secondary side uses a synchronous rectifier design with DC-to-DC converters on the X-Connect board for the +3.3V and +5V outputs. All of the capacitors are high-quality Japanese made components with predominately electrolytics on the main PCB and solid polymer caps on the X-Connect board. The two primary capacitors are made by Nippon Chemi-Con and rated for 270uF, 420V, and 105°C.
