> ... and now you want to tell them they're gonna have to buy a whole new PSU?

I saw the connector and did a double take, it has a third row of smaller signal pins which none of my existing power supplies have. Not even my newest which is a 750W from last year. Sone new gpu power connector. So I assume most people had to buy a new psu anyway.

I am all for higher voltage. 24V is the standard in industrial automation as well as off highway machinery and european trucks. 48V is common in telco but positive ground though it is common in industry; I use 48v supplies for small stepper and servo motor amplifiers for motion control.



People haven't had to buy new PSUs. The adapter has the circuitry built in to detect how many of the connections are populated. For each one, the 40xx cards will raise their power limits by 150W.


fun fact - that circuity is totally superfluous. Connector itself has 4 small pins underneath main ones specifically for detection. Nvidia did Apple here inventing stupid shit to make it proprietary. All this circuity does is 4 to 2 binary encoding.


It's not proprietary, the connector is called 12VHPWR and it's specified by the PCI SIG.


Not the connector, additional useless chip Nvidia put in it encoding 4 signals into two pins, and leaving 2 remaining pins unpopulated.


Usefull to have unused pins, if you have to update it to support 1000w in the future


Sometimes its good to stop and think a second longer. This "600W" connector is already melting, and you want to pump 1000W thru it?
