Corsair undoubtedly is one of the most active players in the PSU market. Aside from several series and tens of power supply units available, they have a very active R&D department as well. Today we will be having a look at the AX1200i, the second most powerful unit of the premium AX series. Although the AX1200i is only the second most powerful unit after Corsair’s pinnacle, the AX1500i, the price difference between these two units is $150, making the AX1200i a more reasonable choice for anyone who is financially conscious. How well it can perform? We will see that in this review.
