are the benefits of a power supply that is compliant
with the latest Intel ATX12 V2.0 guideline?
1.Increased +12V power, and dual independent +12V output
circuitry for safer, more reliable output to all components.
2.Reduced current capacity on +3.3V and +5V lines to match
decreased demand with modern PC and ensures maximum current
is available on the 12V lines.
3.Supports the BTX and IPC standard 24-pin main power
connector for more flexibility
4.Support for PCI Express; all Seasonic models rated at
450+ watts will include a 6-pin PSU connector for PCI
Express graphic cards.
an older-version power supply fitted with a + 24-pin main
power adapter work as well as the new version - ATX12V2.0
Many power supply companies tried to make a quick upgrade to
the new Intel ATX12 V2.0 standard by attaching a 24-pin adapter
to their existing power supplies. In the long run this is not
a viable alternative to a real ATX12V v2.0 version power supply.
1.+12V line current may remain inadequate,
2.Due to the high current draw of ATX12V V2.0 hardware, such
adapters can lead to voltage drops that cause power instability.
can I tell whether a power supply is compliant with the
latest Intel ATX12V v2.0 design guide?
1.The statement of ATX12V V2.0 compliance must be clearly marked
on the product label, and the specifications on the label must
indicate the presences of two independent +12V lines.
2.A 24-pin Main Power Connector is used.
3.The 6-pin AUX power connector has been removed
4.Efficiency is > 70% at full load; and at >60% at light
are the advantages of the new design of twisted
wires in the Seasonic S12 series?
1. Better EMI results
2. Reduces impedance to doubles the airflow, ensuring
3. Easy-to-manage cables for improved airflow, thermals
