52030C10 PCD2.W200 is obtained by any combination of output cables
Instead of adding more current limiting circuits, many manufacturers choose to ignore this requirement and raise the current limit above 20 A per supply rail, or provide a “monorail” power supply that omits the current limiting circuit. In some cases, violating their own advertising claims to include it. [12] As a result of the above standards, almost all high power supplies claim to achieve an independent supply rail, but this claim is often wrong; Many omit the necessary current-limiting circuit, [13] partly for reasons and partly because this is off-putting to consumers. [14](This absence was, and is, sometimes advertised as a feature under names like “track fusion” or “flow sharing.”)
As a result, the requirement was withdrawn, however, the issue left its mark on the PSU design, which can be divided into monorail and multi-track designs. Both can (and often do) include a current limiting controller. Starting with ATX 2.31, the output current of the monorail design can be obtained through any combination of output cables, leaving the management and safe distribution of the load to the user. Multitrack designs do the same, but limit the current provided to each connector (or group of connectors), and the limit is a manufacturer’s choice, not set by the ATX standard.
Since 2011, Fujitsu and other *** manufacturers [15] have been making systems incorporating motherboard variants that require only a 12 V power supply from a custom PSU, which is typically rated at 250-300 wDC to DC conversion, providing 5 V and 3.3 V, which are done on the motherboard; The proposal proposed that the 5 V and 12 V power supply for other devices such as hard drives would be obtained from the motherboard, rather than from the PSU itself, although this does not appear to have been fully realized as of January 2012.
