The lists of power supplies have been provided to Intel dealers as an aid in the system integration process. Intel has determined that the power supplies meet MINIMUM electrical, mechanical fit and functional compatibility with Intel® boxed desktop boards and Intel® boxed Pentium® D or Pentium® 4 processors or Intel® Core™ 2 Duo Processor.
- Evaluations for any individual system configuration are considered the responsibility of the integrator and/or system OEM.
- Integrator and/or system OEM are responsible to submit their integrated system for safety compliance for their target market. Please select components, in particular power supplies, with appropriate specifications and certifications (for example UL Recognition) to produce a product compliant with safety regulations and standards for the target market. Please contact their power supply vendors for additional information regarding the selected unit’s specifications, certifications and the specific use conditions associated with it. Not all power supplies on the list are suitable for all regions and applications, evaluation of suitability for use in a particular system and market is the responsibility of the integrator and/or system OEM. If the selected power supply has any single output rated at more than 240VA contact with circuits connected to the output must be prevented in user access areas, protection may be achieved by insulation, guarding or interlocks (refer to IEC 60950-1 First Edition, 2001 Clauses 0.2.2 and 2.1)
