Cooler Master Has 70 Power Supplies That Are Intel Haswell CPU Ready
There has been a lot of talk about PSU compatibility for Intel’s upcoming 4th Generation Core Processors (code named Haswell) and Cooler Master feels there is a large amount of misinformation being spread. They are calling for calm and have reassured the public that the vast majority of their power supplies are ready for Haswell. You can see the entire list of 70 Cooler Master Power Supplies that are Intel Haswell ready here. Below are some quick facts that the public should be aware.
- Most power supplies don’t support Haswell – False
- I need a Haswell certified power supply to build a Haswell system – False
- Haswell only works with DC-DC Power Supplies – False
- Haswell only works with 80+ Gold and better Power Supplies – False
- Haswell requires a second 12V rail and doesn’t work with single rail Power Supplies – False
- On some older power supplies, Haswell consumes 5W more in idle mode – True
Among other improvements of Intels latest Core Processors, power consumption in idle mode has been greatly reduced from around 6W to less than 1W. This might cause some older power supplies to shut the system off when the CPU enters idle mode, or prevent the system from waking up out of sleep mode. To our knowledge all mainboard vendors will disable this advanced power saving mode by default, and no customer upgrading to Haswell should experience any issues whatsoever. Should customers experience problems nevertheless, or would like to enable the advanced power saving mode on older power supplies that might not support it, there is a simple fix. Simply adding a single silent case fan to the system, connected to the power supply, should provide enough additional load to keep the system running in advanced power saving mode.
The only disadvantage would be that power savings in idle mode on such a system would only surmount to around 2-3W instead of ~5W.
