Labeling and Marking (Recommended)
The following is a non-inclusive list of suggested markings for each power supply unit. Product regulation stipulations for sale into various geographies may impose additional labeling requirements.
Manufacturer information: manufacturer's name, part number and lot date code, etc., in human-readable text and/or bar code formats.
Nominal AC input operating voltages (100-127 VAC and 200-240 VAC) and current rating certified by all applicable safety agencies.
DC output voltages and current ratings.
Revision number of the ATX12VO, SFX12VO, etc. specification that the power supply meets.
Access warning text (“Do not remove this cover. Trained service personnel only. No user serviceable components inside.”) must be in English, German, Spanish, French, Chinese, and Japanese with universal warning markings.
Power Supplies are recommended to list if it meets the Recommended Timing values (T1 & T3) in product documentation. There are two levels of timing for T1 and T3 a power supply can support as detailed in Table 4-8. This will help power supplies that meet the lower T1 & T3 timing values highlight that it meets the lower timing values to OEMs and end users.
12VHPWR connector/cable harnesses that are hard-wired to the power supply shall be labeled indicating the maximum power supported according to the Sense0/1 encoding implemented for each connector. If the Sense lines are dynamic (can change in standby mode only), the product documentation must describe the power levels supported based on the number of PCIe* Add-in Cards connected. Sense0/1 are described in Section 3.3.1 of this document as illustrated in Figure 5-1 below.
