Enhance have been a major switching power supply manufacturer since 1986. Its product quality, competitive price, global operation and service, technical design and support excellence are the major reasons to choose Enhance as a primary vendor.

The following are the mechanical considerations when choosing a power supply:
Thermal Considerations:
What is the thermal environment of the power supply? Ambient temperature & temperature rise within the product. What options do you have to keep the power supply running within its intended operating range. No airflow, convection airflow, forced airflow. Conduction?
Electrical Considerations:
DC input or AC input. What is the desired range of the input? If it is Switching AC input model, the approval agencies may eventually require you to have harmonic correction. If a linear power supply will fit the specifications you desire, you will not be able to use the same model for worldwide input. How many output voltages are required? How tightly do they have to be regulated? What is the duty cycle of each output and how do they relate to each other? What is the output peak requirement for each output and for what duration?
Logic & Controls:
What signals do you require from the power supply such as "power good/fail"? What signals do you want to send to the power supply such as "remote enable" or "margin"? Do you need a voltage adjustment pot or remote sense on one or more outputs? Do you need "Standby Voltage" to keep a processor idle until called upon to "wake up" by the operator?
Approval Agencies:
If your product is to eventually be sold in Europe, you will want to consider the CD mark. If it is only going to remain in the United States, you can probably do with the appropriate UL mark.

POST is a new innovation design to help users easily determine if the power supply working properly. Simply plug-in the AC power cord and press the POST button, the internal embedded chip will generate a signal to perform self diagnostic. If all internal components and circuitry perform properly, the power supply will activate the cooling fan and light up the GREEN power-on status indicator. It tells user there is no problem found inside of power supply.
Available Model: ATX-1136H-PDB-R

Yes, please visit AMD ( www.amd.com ) and Intel ( www.intel.com ) web site for more detail test report.

Yes, Enhance power supply is designed to meet industry standard. It will work for your Current PC as long as its physical dimension, output wattage and the original PC power supply is industry standard compliant as well.

Enhance have been working with industry leader such as AMD and Intel to make sure product compliant to industry standard form factor. Besides, Enhance also alliance with major motherboard manufacturers (Asus, Aopen, ECS, FIC, Intel, Iwill, Giga-Byte, Microstar, SuperMicro, Tyan, etc.) and Chassis vendors (Chenbro, Enlight, Evercase, Fong-Kai, Gigacase/Yeong-Yong, Min Maw Int'l.., etc.) to ensure product best performance.

Unfortunately, No. ATX power supply is not compatible with AT form factor. You cannot use ATX power supply unless replace the motherboard with the same form factor at the same time.

Please refer to the power supply design guide for each different form factor. ATX/ATX12V ; EPS12V; SFX/SFX12V
