Wieso haben manche Netzteile zwei oder mehr 12V-Schienen?

Hallo,

kann mir einer mal sagen, wiewßhalb manche Netzteile zwei oder mehr 12V-Schienen haben? Das Corsair VX550W hat bspw. nur eine 12V-Schiene mit 41A, dagegen hat das Corsair HX520W gleich drei davon mit je 18A.

PS: ATX12V 2.0
ATX 450 PHF.

The above conclusion was incorporated in ATX12V 2.0 (introduced in February 2003), which defined quite different power distribution from ATX12V 1.x:

* The main ATX power connector was extended to 24 pins (it is backwards compatible). The extra four pins provide one additional 3.3 V, 5 V and 12 V circuit.
* The 6-pin AUX connector from ATX12V 1.x was removed because the extra 3.3 V and 5 V circuits which it provided are now incorporated in the 24-pin main connector.
* Most power is now provided on 12 V rails. The standard specifies that two independent 12 V rails (12 V2 for the 4 pin connector and 12 V1 for everything else) with independent overcurrent protection are needed to meet the power requirements safely (some very high power PSUs have more than two rails, recommendations for such large PSUs are not given by the standard).
* The power on 3.3 V and 5 V rails was significantly reduced.
* The power supply is required to include a Serial ATA power cable.
* Many other specification changes and additions.
