Reason of this Question,

: recently, 1 psu manufacturer in Korea, attacked seriously by hardware review site.
I think they trying to sniping, So, I need exact knowledge about PSU.

Please see below documents,

http://www.tomshardware.com/reviews/power-supply-specifications-atx-reference,3061-12.html

Table in the document (CTRL+F and standard terminals please,,,)


Only two +12 V pins are used in the six-pin connector, even though most power supplies include three.

Standard terminals are rated eight amps.
HCS terminals are rated 11 amps.
Plus HCS terminals are rated 12 amps.
All ratings assume Mini-Fit Jr. connectors using 18-gauge wire under standard temperature conditions.



Please let me know,

Standard terminals are rated 8 amps,,

What exactly this mean?

Is it mean, single 12v pin can afford to 8 amps?

OR, entire 6 pin connector( two 12v pin ) can supply 8 amps?















 
Solution
Read a little further down the page, it says "Each pin in the PCI Express auxiliary power connectors is rated to handle up to 8 amps of current using standard terminals—more if using HCS or Plus HCS terminals."

Hi,

It means that single +12V pin can deliver 8,11 or 12 amps. It's due to wire gauge (18 should be achieved) and connector design.
For security reasons you have GPU's up to 150W (actually even less) that have 6 pin connector (75W through 6pin + 75W through PCIE). That applies for stronger GPU's also. Where you could in theory have only one 6 pin connector you need to provide 8 pin connector for security and durability.


Best regards :)
