Following the announcements from other power supply manufacturers, Seasonic has now released a list of its own power supplies that are compatible with Intel's upcoming Haswell processor. The new Haswell CPUs, set to launch June 3rd, incorporate new C6 and C7 sleep states that draw as little as 0.05A from the 12V PSU rail. Because of the low load, some existing power supplies will have issues with the new sleep states and could result in system instability. In light of that, many manufacturers are validating their existing lineups to determine which ones are compatible.

As of the time of publication, the following power supplies from Seasonic are compatible with Haswell and the new sleep states.
