The digital platform allows for OCP adjustments at 12V. At 12V, only the Super Flower Leadex platform has a small lead, without using any digital circuits. Transient response is excellent on all rails, especially the minor ones where the AX1600i smokes the competition. The AX1500i was already a difficult opponent for the competition the AX1600i is on a different level, not leaving any room for doubt about who is the performance king. The AX1600i puts to shame all other platforms regarding average efficiency, thanks to its totem-pole APFC converter.
PC GAMER KENSHI REVIEW FULL
The bulk caps have enough capacity to provide a long hold-up time, even when the PSU operates at full load, and the inrush currents are super-low.Įfficiency is high under both normal and light loads, especially the 5VSB rail. Looking to performance, and load regulation is super-tight on all rails and ripple suppression is excellent. This is why totem-pole PFCs achieve up to 99% efficiency, while the most efficient APFC circuits top out around 96%. In a totem-pole PFC, the signal passes through a MOSFET and a MODFET in both cases, so we theoretically have no voltage drops. When the conduction path is off, the signal passes from two low-speed diodes and a high-speed diode (SBR). Some more details about the total-pole APFC that the AX1600i uses and why it offers increased efficiency: In a conventional APFC converter, when the conduction path is on, the signal has to pass through two low-speed diodes (of the bridge rectifiers) and one switch. Given that this PSU is for extreme systems, Corsair could also use a double ball-bearing fan, which is more suitable, than FDB fans, for operation under high operating temperatures. The build quality is top-notch, and the cooling fan uses a fluid dynamic bearing, for increased reliability.
The 12V rail is digitally controlled, while the minor rails and 5VSB use analog controller, to keep the cost and the design’s complexity in control. The totem-pole APFC requires a digital controller, and the AX1600i has two of these, to handle the APFC converter, the primary and secondary sides.
