GTX260 pcie power connectors
The gtx260 has 2 power connectors.
My psu only has 1 pcie power connector, and plenty of unused molex. I went to the store to buy a molex to pcie adapter and was offered 2 options.
1. 1 molex to 1 pcie connector.
2. 2 molex to 1 pcie connector.
Which one was I supposed to get?
Was the 1 molex to 1 pci-e only 6 pin pci-e or 6+2? How many pins do you need for the second power connector on the 260? Should you perhaps consider a better psu?
The 260 should have 2x6 pin for power.
Myself personally I don't like using molex to pci-e power adapters but I do know that sometimes its all you got.
All you would have to pick up was a 2 molex to 6 pin pci-e adapter.
Has enaberif said, the 260 has 2 connectors of 6 pins each.
The 1 molex to pcie was; 1 molex to 1 pcie(6 pins)
The 2 molex to pcie was; 2 molex to 1 pcie(6 pins)
I would have liked to get a better psu, but the difference between a new psu and the adapter is about 100$:haha:
I'm rocking a 500w OCZ psu if anyone is wondering. It's the modular type. And I got it from someone(lcdguy) very generous on this board about 2 years ago.
The 2 molex to 1 pci-e allows the connect to pull power from 2 lines not just 1
Does that mean I should connect each molex to 2 different rails?
I don't know if "rail" is the term I should have used... but you know... on the wires coming out of the PSU, 1 harness may have a bunch of molex, then another harness has another bunch of molex. Should I use 2 molex coming from the same harness, or 1 molex per harness?
The 2 to 1 runs off two seperate lines which means your gonna plug the molex into or should be 2 separate molex lines.
I don't know what video card you are upgrading from or what the rest of your system has maybe you check your requirements with the psu calculator

A 500watt OCZ would make me a little nervous ...
Make sure to factor in at least 20% Capacitor Aging as well.
It recommanded me 321w
The card will replace a 8800GT Alpha Dog in the rig linked to my profile.
