i have a desktop with 4 gb ram ddr3 .......ECS motherboard H61H2-MV and processor i 3 and graphic card ZOTAC NVIDIA GTX660 192-BIT 2 GB DDR5.
I want to ask that i have a Power Supply 450W , can it run that graphic card , there is a 1 x Dual MOLEX to 6-pin PCIe Power Cable in graphic card
So in my PC powersupply there is a 2 Molex pin connector option is there .
Please tell me it will run my graphic card , without buying other Power Supply

Hard to say from the info given, but probably (it can run it).

Without the details of the other stuff in your rig, its hard to calculate the total power draw in your system, but I doubt it over 300 watts. And without the details on that PSU, its hard to tell if it can supply all of that 450 watts at 12vs or not.

Molex is rated for 60 watts at 12v, whilst PCIe is ~70 watts; by combining two molex, you "get there". Your card only needs ~140 watts, and it gets ~75 of those from the motherboard itself (which is why the single PCIe connection is enough). The two molex to pcie connector should be okay.

That said, I'd read up on quality power supplies, and do some more homework on whats in your rig.

The minimum power requirement is 450W for the GTX 660 and it requires a 6-pin PCI-E power connector. The 1 x Dual MOLEX to 6-pin PCIe Power Cable should help you if you don't have a PCI-E power connector. So, the card should be working fine. Although it is suggested to use the PCI-E power connector from the power supply rather than a 1 x Dual MOLEX to 6-pin PCIe Power Cable.

I could better guide you if you share the model of the power supply you have.
