Sorry you must be uninformed i use sata connectors plenty of time's with graphic cards they are well and capable of running graphic cards infact they problably better than the 4 and 6pin cable assigned themselves,
I'm not as nice as these guys, so I'm going to just say it right out front and put it on notice. Either PUT UP the evidence that you suggest exists, or we'll remove the post AND issue a warning for intentionally providing false and misleading information that is likely to result in the potential for harm or at the very least, problems, with users systems who come along and see your post.
In point of fact, it's pure BS. Plain and simple. You say it's not? Fine. Show us the evidence. Show us ONE example of ANY power supply oriented electronics engineer or specialist/reviewer, that is known and reputable, saying that what you are indicating is factual. Because I'm telling you that you are full of crap and I think you know it as well as we do. I'm calling foul/troll, and that angers me because it means you are less than thoughtless when it comes to the other members of our community or anybody who might happen to drive by.
I on the other hand, will be happy to provide the evidence to the contrary, which is clearly out there for anybody to see.
- 6-pin PCI-e Power cable is rated for 75 watts/13 amps, the same amount given by the PCI-e lane on the motherboard.
- Molex is rated for 132 watts/11 amps.
- SATA is rated for 54 watts/4.5 amps. - Do not convert from SATA to Molex/6-pin, this will cause an overdraw and could result in a fire.
By comparison, the PCIe 6 pin connector MUST be capable of providing up to 75w of power, while the 6+2 or 8 pin must be capable of handling 150w. Both of which are significantly more than the 54w the SATA connector and associated wiring is rated and designed to be capable of handling.
Plus, the bottom line is, ANY power supply that is CAPABLE enough that the manufacturer believes it to be able to support the use of a specific connector, WOULD ALREADY INCLUDE that connector with the unit. The fact that it is absent tells you ALL YOU NEED TO KNOW about whether or not that unit is capable and reliable for that type of connection or not. Manufacturers don't leave off connectors because they just don't like them, or because saving fifty cents worth of wire and plastic is going to drastically improve their margins. They leave them off because they know the unit is not capable enough or safe, to be used with that kind of power draw. Trying to do it through a circuit that was never intended for that use simply increases the risk, exponentially.
