Corsair AX1200 Power Supply Review

The Corsair AX1200 arrives in one of the largest power supply boxes we have ever seen, and just for reference we placed a Blackberry phone beside it. Its huuuggee.

Inside the box there is a manual, reviewers guide (which you won’t get if you buy one obviously) and a bag with all the modular cables inside. They also supply mounting screws and cable ties to neaten up your system build.

The reviewers guide explains about synchronous rectification on the outputs and Zero voltage and zero current switching on the primary side to help the unit reach the remarkable quoted efficiency levels.

The storage bag within the box is extremely big and all the cables are supplied inside.

Type Of Connector Corsair AX1200
ATX Connector (600mm) 20+4pin
6+2 Pin PCIe (610mm) 6
SATA (400mm+90mm) 4
SATA (440mm+90mm+90mm+90mm) 12
4+4 Pin EPS12V/ATX12V connector (610mm) 2
5.25″ Drive (460mm+110mm+110mm) 12
5.25-3.5″ Drive Adapter (100mm) 2

There are enough cables included to support even the most demanding of system builds. Some are sleeved ribbon design and others are flat black ribbon.

The power supply itself is wedged between two heavy duty blocks of styrofoam and it is encased within a felt bag . When you remove the PSU from the felt bag, yes there is another protective cover. We would be safe in saying that if this unit arrives damaged, then your postman needs a slapping.

Corsair AX1200 +3.3V +5V +12V -12V +5VSB

Max Power 180W 1204.8W 9.6A 17.5W
1204.8W

Yes you read that right, 100.4A on the 12V rail. This is a simply staggering level of power to be delivering down a single line and is without a doubt the highest we have seen. Even the Silverstone Zeus ZM1200M which resides in our labs falls short of this mark.

Is this enough connectivity for you? Yes we thought so.

The top is home to a 140mm fan – we like the aesthetics of the unit, its a simple ‘black’ design throughout, no controversial gold fans here (opps sorry Enermax).
