I am soon to be upgrading my GTX 560 Ti graphics card to the new GTX 760, and I need to upgrade my current power supply,
http://www.newegg.com/Product/Product.aspx?Item=N82E16817171031
in order to support the a 6+2 pin, because that one only has one 6-pin connector. I found an old power supply in my closet, and it is older than my current one, but it has 2 6 pin adapters which is what I need.

However, this PSU only has one 4 pin CPU connector, and my current motherboard,

requires 2 CPU power connectors. Would I be able to use this adapter to make it work? Or is this not a reliable method?

Your antec 550 should be enough: it's just closer to the edge than I like to be. The formal PSU spec for a 760 is 500W with 30A on the 12V. Your Antec is rated for 38A. I think you're OK if you don't plan on overclocking the GPU.

But to answer your question: it's a bad situation when the PSU can't supply enough power to a component. This can cause many problems, such as system instability and/or hardware damage, and can even cause the "magic smoke" to leak out of your PSU :(

The GTX780 needs a minimum 600W PSU with at least 42 amps from the 12V rail. Your old Antec isn't going to cut it.

Edit: I see you're getiing a 760, not a 780. My eyes aren't what they used to be... Your plan should work with the 760, but it's a close call. Give it a try, but be aware that you might need to shell out for a bigger PSU.

Alright, thanks your your answer, but is there any way my current power supply could support the 760? Buying a new power supply is kind of a pain, but is there any way I could get like a 4-pin molex to a 6+2 pin connector?

Your 500W Coolermaster can supply 12V at 36A. You're still close to the edge, but it should work OK, just don't even try to overclock the GPU.

I've used those Molex adapters before without any trouble.
