How to determine if a power supply has a four-pin CPU connector?

I recently bought a power supply for an HP Envy 700-056, with an AMD A10-6700 processor. However, the very last cable I had to hook up was the CPU cable; unfortunately, the connector was a six-pin connector, and the motherboard connector is a four-pin.

How do I determine the best match for a power supply? Please let me know if any other product specifications would be of assistance.

I like the corsair line, and am looking at a 550W supply on Newegg, as I really don't need much more than that with the components I have (or would possibly add in future).

Thanks for any help!

Okay, did a little research.

Actually, looking again at the CPU connector, it is an eight-pin, not six. So, looking at some forums, I found that the eight-pin connector really is two four-pins with a friction connection, and separating the two four-pins gives me the four-pin connection.

My question now is this issue the manufacturer points out: "The detachable four-pin from the 24-pin main connector is not a “P4” or “+12V” connector". I have scoured the HP product info and am unable to determine whether this four-pin connector will be sufficient for the motherboard CPU connection or whether it is an incompatible connection.

You called it right, Rolli. This is why I come to Tom's Hardware looking for real answers.

So it is a 4+4 pin that comes apart into 2x4 pin. Now just need to figure out whether this four-pin is the right connection for the CPU. Still not sure whether it not being a P4 or +12V connector is a problem?

The power supply is a CORSAIR GS series GS700 700W ATX12V v2.3 SLI Ready CrossFire Ready 80 PLUS BRONZE Certified Active PFC Power Supply New 4th Gen CPU Certified Haswell Ready unit.

The PC I am attempting to install it on is an HP Envy 700-056 with an AMD Elite Quad-Core A10-6700 Accelerated Processor (Richland) with (now disabled) AMD Radeon HD 8670D Integrated Graphics (I have installed an ASUS Radeon HD 7750 and to get it to work I had to disable the on-board graphics).

The Motherboard is a MS-7778 (JasmineR). Chipset is AMD A75 FCH.

yea...I was stuck on this ...I saw a 6 pin PCI-e connector and the 8-pin connector coming off my PSU.......I connected 4 pins of the 6-pin PCI-e to my 4 pin motherboard connection....that DIDN'T WORK............So I be doing some reading here.....and sure enough..there's the answer,...it's an 8-pin connector that splits into (2) 4-pin connectors...BINGO!
I ran to my PSU ..and sure enough the 8-pin came apart...YAY!...I don't have to return the PSU...I don't have to steal a PSU from my son's unused PC....I can put the PSU from the Dell that I thought might work back in the Dell...YAY!
