In early 2020, ATX standard setters intel introduced a new generation ATX power supply specifications: ATX12VO, where the “O” on behalf of “Only”. And follows the previous ten years the biggest difference ATX2.31 is canceled 5V, 3.3V voltage accessories and other peripherals, leaving only the 12V voltage, from 24pin interface board also become 10pin, means that more than a decade of silence motherboard Electrical market ushered in a major innovation.
HuntKey Group since its establishment temper roots in the power industry for 26 years, it is the leading power supply manufacturers enterprises, today’s power adapters, chargers and other products covered by many of the world market terminal domain, can fully meet the needs of users at all levels. The face of the arrival of the new standard ATX power supply, HuntKey ahead of the layout ATX12VO related products, launched HuntKey 180W PC power supply HK280-23PP, let’s take a look at the specifications of this new power in the end there are those differences.
ATX Power Development Brief
Desktop computer ATX standard has been with us through many years, ATX power supply specification was first developed by intel in 1995, has gone through several versions iteration. If the computer in the 1990s played the players should know that the ancient ATX2.0 specification of the motherboard power supply interface for the 20-pin, CPU power supply also take power from 20pin interface 3.3V, D-shaped peripheral interface big mouth.
With the increase in CPU power, ATX specification ushered in the first major replacement, added a separate 12V 4pin CPU power supply interface, providing strong support for the CPU power, version number naming to adjust, change ATX12V1.0, and ATX12V1. version 3 was added to the S-ATA peripheral Interface. After PCI-E interface cards began to spread, 12V start adding multi-way power supply, ATX power standards also will be upgraded to ATX12V2.0,20pin adjust the interface upgrade to 24pin. In recent years, in order to respond flexibly to use with different power CPU and graphics card, power supply standard and return to single 12V power output, iteration to ATX2.31 through multiple versions, still in use.
Why keep only 12V?
ATX12VO PC power supply specification, “O” on behalf of “Only”, indicating that only 12V supply output. Why should cancel other voltages retain only 12V? Previous chassis peripherals mainly hard drives, optical drives, fans, a very ancient old CPU also has a 3.3V power supply. Now the drive has been eliminated, SATA hard drive NVME line gradually transition to the motherboard and the fan controller board is also attributed to the direct management, as power-hungry CPU, graphics card already full 12V supply, the traditional 5V, 3.3V has little effect .
Peripheral how to do?
Currently ASRock has launched its first motherboard based on ATX12VO power supply design specification: Z490 Phantom Gaming 4SR, you can see from the motherboard power connector, 24pin interface to the original disappeared, replaced by a new 10pin input interface, you can also see two small 4pin SATA interface is used to supply output peripherals. After ATX12VO canceled other voltages, the power supply to the peripherals responsible motherboard, the motherboard added 5V buck circuit providing support for other peripherals.
Huntkey Power ATX12VO
HuntKey HK280-23PP power electroplating metal shell production, appearance and consistency conventional ATX power, before and after heat-through design, the parameters attached to the side plate, since only the voltage of 12V, the cable can be seen that significantly less lead than the traditional cable ATX .
Behind square punching cooling network, built 8cm active cooling fan, an input interface is a common three-prong socket product word.
Size, power HuntKey HK280-23PP 85mm width and height, respectively, consistent with the power supply size 150mm X ATX standard, four screw mounting hole location is exactly the same, may be used ATX chassis perfect adaptation. Only terms of length 100mm, ATX power supply common length is generally between 140 to 160, this product is HuntKey short section design.
10pin cable interface
On the interface you can see a very obvious change, HuntKey HK280-23PP power based ATX12VO standard production, leaving only the 12V output voltage, the joint is not the traditional ATX power supply 24pin, but with a new 10pin interface. Total cable from yellow + 12V, green PS / ON, blue -12V, GND black composition. Also with a 4pin interface is CPU power connector.
The ATX12VO intel published specifications can be found, 10pin interface contains only three main 12V supply cable, from a 5V standby voltage becomes 12V.
10pin motherboard connection cable length is 30cm.
4pin power to the CPU for the cable length of 60cm.
AC input: 200-240V ~, 50 / 60Hz, 3A
DC output: + 12V15A (yellow line) -12V0.2A (blue line)
Rated output power: 180W
+ 12V output not exceeding 180W
-12V output does not exceed 2.4A
Manufacturer: Shenzhen Huntkey Electric Co., Ltd. Chi source
Products made 80 PLUS certification, through the national 3C mandatory standards.
Charging head network summary
Huntkey PC power supply as the old brand is the first time to bring a new standard first products for the next generation of spy power industry standards, HuntKey HK280-23PP power based on a new ATX12VO standards development, easier 10pin motherboard power connector, plug is no longer required feeding strength, and the alignment is more beautiful. Canceled 3.3V, 5V circuit section, more simplified circuit design efficiency focused on providing clean 12V DC power supply as a PC.
Currently ATX12VO PC power supply standard has not yet large-scale commercial, but I think this is definitely the future mainstream, follow Huntkey will also continue to publish a series of different power ATX12VO PC power supply, to provide a stable power supply services for computer accessories.
