All of Huntkey's PSUs Are Ready for Intel Haswell Processors
SHENZHEN, China, Aug. 20, 2013 /PRNewswire/ – Huntkey Enterprise Group, a global professional power supply provider, has published its collection of Haswell-ready PSUs.
Intel's 4th Generation Core Processors (named Haswell, a follow-up to last year's Ivy Bridge), were released in early June, bringing with them the usual inter-generational IPC (instructions per clock) improvements. When the CPU is in deep sleep mode, the power dissipation recedes to just 0.05A (0.6W), 10 times below Ivy Bridge. As Intel's fourth-generation Core-series central processing units are so power efficient and able to go into a lower power sleep state than any previous processor, concerns have arisen regarding PSU compatibility with the new processor.
Thus, Huntkey have been rigorously testing their power supplies to determine which ones are able to handle Haswell's C6/C7 states. Luckily, all of Huntkey's power supplies have been certified to run Haswell.
After assembling the system, Mr Zhong, an engineer from Huntkey, connected a Power Meter in series with the computer power supply to indicate the computer input power. At the same time, he connected an Ammeter in series with the cut yellow wire in the CPU interface, which was used for reading the CPU power.
System hardware configuration list:
CPU：i5-4570, 4 core
M/B: Gigabyte GA- B85 -HD3 (BIOS Version: F3)
MEM: 4G DDR3-1600 GSKILL
HDD: seagate 160G 7200RPM
Enable C6/C7 mode from BIOS when turning on the computer.
Boot up system and check system configuration in the Power Meter Panel and Ammeter Panel.
Booting Up Configuration - Power Meter: 55W-60W Ammeter: 2.3A-3.0A
Keep present application and leave the system idle.
Idle Configuration - Power Meter: 35.5W Ammeter: 0.8A
Go into Microsoft© Windows "HIBERNATION MODE", then Intel® Haswell processor will go to C6/C7 energy-saving mode. CPU and PSU cooling fans freeze in this stage.
"HIBERNATION MODE" Configuration - Power Meter: 32.8W Ammeter: 0.63A
"DEEP HIBERNATION MODE" Configuration - Power Meter: 0W Ammeter: 0A
Click mouse button or type on the keyboard to wake system up, then you can see the applications in Windows before hibernation. As shown in the pictures, the system can wake up properly except when shutting down showing that the PSU is compatible with Haswell C6/C7 states.
Huntkey has already tried to test several Haswell platforms to ensure compatibility. End users and system integrators can build a new Haswell system using Huntkey power supplies.
