SkyHawk Power ONE 570W Power Supply w/Audio Stand-By


Skyhawk's GM line of Power ONE power supplies are available in various wattages and can be combine with several options. One of the defining features of these power supplies are the "Smart Cable Management" system, which allows the user to connect only the cables that are needed. An interesting option available is the "Audio Stand-By" feature, this provides an additional +12V rail that is always on and capable of powering a CD-ROM drive to play CD audio when the computer is off.


Important Update:

The specifications on the box for models ATX-GM 470PC, ATX-GM 520SC, ATX-GM 570PC, and ATX-GM 620SC list the power supply as having dual 12V rails, and is supposed to comply with Intel ATX12V V2.0, Intel EPS12V V2.1, and AMD ATX-GES guidelines, unfortunately it does not. First discovered by the guys at Legit Reviews, all the 12V wires are connected to a common source (instead of two independent sources). In our opinion this does not make it comply to ATX12V V2.0 requirements, and it certainly does not meet EPS12V V2.1 requirements.

EPS12V V2.1 specifications clearly state that the CPU and the rest of the system should have separate 12V rails, and that the two rails "... should not be connected together on the baseboard ..."

Intel ATX12V V2.0 specifications are not as detailed on the matter, and while it doesn't explicitly state "they must be separate on the baseboard", every manufacturer thus far has taken the assumption (and common sense) that they should be when designing a power supply to conform to the specs.

We cracked open our PSU so that we could verify the results as discovered by others, and indeed there is only a single 12V source out as can be seen in the picture below.

SkyHawk has informed the public that any customer unhappy with the ATX12V 2.0 or EPS12V 2.1 compliance on one of the above mentioned power supplies can contact their retailer for a refund. Also SkyHawk has put a request in to change the design of the power supply, and alter the wording on the box / labels.
