Seasonic "S12" 430w PSU Review

TweakTown Rating: 9.0%Manufacturer: Seasonic USA



For those who have dealt with the Seasonic line before, you'll remember that they are about efficiency. Their newest models still work on this same model. In essence, the higher the efficiency of the power supply, the less power it consumes from the outlet and the less heat it is required to dissipate. Seasonic has been making an 80% efficient PSU for a while now. To give you a comparison, other manufacturers often put out models that are less than 70% efficient.


This particular power supply also uses an Active PFC (Power Factor Correction) that allows for a cleaner and more stable power level to be transmitted along all voltage rails. While I haven't found any significant differences in performances between those that have and don't have this feature, it certainly doesn't hurt.


Add into this the automatic detection of outlet voltages and the cable management kit and you'll find yourself with a well-rounded power supply. With a price of about US$90-100, it falls in the realm of what you would expect to pay for a performance PSU.


Bottom line... If you're looking for a power supply to handle the rigors of an enthusiast system, then keep the Seasonic S12 series in mind as one of your choices. With higher efficiency than many other models on the market and a stable supply of power along all voltage rails, it won't leave you lacking when it comes time for the high-end performance we need for today's power rigs.


- Pros


Stable power along rails


Includes cable management kit


High efficiency


Automatic voltage detection from outlet

Could use some more 4-pin Molex connectors
