I have 6x2gb sticks of DDR3 ram, from several different brands. 

Here is what I got:

4x Hynix
1x Micron
1x Samsung 

They are all functional, and were pulled out of working, running systems!

DDR3 2gb Sticks

I have 3 of these! They were all pulled out of working systems, and come with a power cable!

As far as connectors go, they each have the standard 24 pin motherboard cable, a 4pin CPU cable, and 4 sata power connectors. 
They do not have GPU 2x6 pin or 2x8 pin cables.

They are capable of delivering up to 275 watts, and would be great for a low powered, hyper budget PC.
