5.2.2.4 PCI Express* (PCIe*) Add-in-Card Connectors (Recommended)
These are optional connectors for the power supply to support additional power
needed by any PCI Express* Add-in Card (AIC). The most common PCIe* Add-in Card
that uses these connectors are discrete graphics cards. The PCIe* CEM Specification
defines different connectors based on the power used by the Add-in Card which can
range from 75 watts up to 600 watts.
5.2.2.4.1 PCI Express* (PCIe*) 2x3 Auxiliary Power Connector
(Recommended)
The 2x3 Power Connector is designed to provide 75 watts to the PCIe* Add-In-Card(s)
and has the following requirements:
• Current Rating: 8.0 A/pin/position maximum to a 30 °C T-Rise above ambient
temperature conditions at +12 VDC, all six contacts energized.
• Mated Connector Retention: 30.00 N minimum when plug pulled axially.
Cable Assembly Contact and Housing Details:
• Housing Material: Thermoplastic
• Pin Contact Base Material: Brass alloy or equivalent
• Pin Contact Plating: Sn alloy
• Flammability: UL94V-1 Minimum - Material certification or certificate of compliance
is required with each lot to satisfy the Underwriters Laboratories follow-up service
requirements.
• Lead Free Soldering: Connector must be compatible with lead free soldering process
