This chapter contains mechanical guidelines that apply to desktop power supplies
regardless of mechanical form factor. For mechanical form factor specific design
guides, refer to Section 11 through Section 15
.
5.1 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 PSU is a modular design or if the Sense
lines are dynamic (can change in standby mode only), another location on the PSU
(highly recommended to be on the PSU Voltage Rail label) and the product
documentation must describe the power levels supported. If the criteria for different
power levels based on the number of PCIe* Add-in Cards connected that must be
described for the OEM or end user as well. Sense0/1 are described in Section 3.3.1
of
this document as illustrated in Figure 5-1 below.
