Style Compliance
Devices are designed for specific types of cases. A variety of computer motherboard styles and cases are available. Most case styles have a corresponding power supply type.


	Style
	Your choices are...
	ATX		Devices are designed specifically for the ATX case.
	FlexATX		Devices are designed specifically for the FlexATX case.
	microATX		Devices are designed specifically for the microATX case.
	AT		Devices are designed specifically for the AT case.
	LPX		Devices are designed specifically for the LPX case.
	NLX		Devices are designed specifically for the NLX case.
	SFX		Devises are designed specifically for the SFX case.
	TFX		Devices are designed specifically for the TFX case.
	Other		Other unlisted, specialized or proprietary styles.
	Search Logic:		All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches.

	RoHS Compliant		Restriction of Hazardous Substances (RoHS) is a European Union (EU) directive that requires all manufacturers of electronic and electrical equipment sold in Europe to demonstrate that their products contain only minimal levels of the following hazardous substances: lead, mercury, cadmium, hexavalent chromium, polybrominated biphenyl and polybrominated diphenyl ether. RoHS will become effective on July 1, 2006.
	Search Logic:		"Required" and "Must Not Have" criteria limit returned matches as specified. Products with optional attributes will be returned for either choice.

	Search Logic:		All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches.

	Number of Outputs		Enter the number of outputs.
	Search Logic:		User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria.

	Minimum DC Output Current		The DC output current corresponds to the primary DC voltage output.
	Search Logic:		All matching products will have a value greater than or equal to the specified value.

	Maximum DC Output Current
	Search Logic:		All matching products will have a value less than or equal to the specified value.

	Power		Enter the output power of the device.
	Search Logic:		User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria.

AC Input


	AC Input Voltage:
	Your choices are...
	115 VAC		Devices accept 115 VAC nominal inputs.
	208 VAC		Devices accept 208 VAC nominal inputs.
	230 VAC		Devices accept 230 VAC nominal inputs.

Features


	Features
	Your choices are...
	Fan Cooled		Devices include a fan for cooling.
	Integral Heatsink		Devices have an integral heatsink for cooling.
	Overcurrent Protection		Overcurrent protection is internal circuitry that limits or shuts down the current output during overcurrent conditions.
	Overvoltage Protection		Overvoltage protection is internal circuitry that limits or shuts down the voltage output during overvoltage conditions. Typically, overvoltage protection is provided for the primary output.
	Power Factor Correction		Power factor correction is used to correct the phase difference between voltage and current in order to optimize power output.
	Remote On / Off Switch		Devices can be turned on and off remotely.
	Short Circuit Protection		Short circuit protection may include electronic current limiting and thermal resets with automatic recovery.
	Water Cooled		Devices are water-cooled for temperature stability.
	Search Logic:		All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches.

Environment


	Operating Temperature:		Enter the operating temperature.
	Search Logic:		User may specify either, both, or neither of the limits in a "From - To" range; when both are specified, matching products will cover entire range. Products returned as matches will meet all specified criteria.
