Thoughts and rating
Corsair has brought together all of its PSU know-how from the previous four years and stuffed it into the 80 PLUS Platinum-rated AX1200i Digital. Based on the AX1200 but improving upon it by raising the efficiency and adding a DSP controller for rock-solid regulation, ripple control and data feedback via LINK, while keeping the fan switched off until load gets close to 500W, it's comfortably Corsair's best-ever supply.
Most premium supplies manage to exceed standard specifications easily enough and are thus more-than competent performers for any high-quality PC, but if you're pushing components to the absolute limit, with sky-high voltages and frequencies, having top-class power is a must. Fitting that bill is the £260 AX1200i, and though it seems expensive on first glance, it'll happily power a system costing over 10x its price.
We're looking forward to Corsair rolling out mainstream wattages in the AX 'i' series soon. A 750W model, with the same quality innards, would provide mass-market appeal.
Bottom line: a very high-quality PSU from start to finish, do consider it if running multiple graphics cards and heavily overclocked CPUs is your cup of tea.

Silent at reasonable loads
DSP data feedback is kinda cool
