Be Quiet! power supplies confirms Intel Haswell ready

Be Quiet! power supply units (PSUs) have been confirmed to be Intel Haswell ready for all current models and series. For those of you that have no heard of Be Quiet! they are a German company that has been the market leader for years. Today they confirmed that all current product lines for power supplies will be compatible with Intel Haswell when it releases. You can go here and read the full details on Intel Haswell’s potential compatibility issues with power supplies. The quick version is that when Intel designed Haswell they were trying to drive power consumption down and so they designed the new C6 and C7 sleep states. When in these states the processor will drop down to a staggering low rate of 0.05 amps. To put that in perspective, Intel Ivy Bridge has a sleep state that only drops down to 0.5 amps. Haswell cuts power 10 times the rate that Ivy Bridge will.

Be Quiet! power supply compatibility:

Dark Power Pro 10:

• All Models – 100% compatibility 

Straight Power E9:

• All Models – 100% compatibility

Pure Power L8:

• All Models – 100% compatibility

System Power 7:

• All Models – 100% compatibility

Pure Power L7:

• 630W – 100% compatibility
• 730W – 100% compatibility

 

As you can see from the list is that all Be Quiet! power supply units will be compatible with Intel Haswell in their current lineup. If you have a Be Quiet! power supply that is older or not on this list but plan to upgrade to Intel Haswell then be ready to mess around with the C6 and C7 states since Intel has ordered all motherboard manufacturers to give users the ability to turn off both of these sleep states in the BIOS. Hopefully this won’t be to painful for anything that does not have a compatible power supply or Be Quiet! among other manufactures will do more test to see is if lower end or older PSUs will be compatible.
