Corsair AX1200i PSU review - Product Showcase

As you can see the PSU is fully modular. Lot's and lots of connections. Even the ATX power header can be detached. See the button on the lower right ? That's a Self-test switch to determine PSU functionality even before installation. Green is good.

And yeah as you can see, a lengthy product alright with a length of 20 cm - it's complete dimensions are 150mm x 86mm x 200mm

At the top you'll stumble into a big yet silent enough, 140 mm. A silent quality fan (double ball bearaing). When load is under 30% the fan will remain off meaning if load stays below roughly 240 Watts, the fan will disable itself.

And check that out, that's 100A on the single 12V rails alone. Nice !  In theory this PSU could hold four GeForce GTX 680 cards or Radeon HD 7970 cards quite easily, and then you can still add a PhysX card and overclock.
