Ok, so I have both 006 molex and 006 6 pin risers. However, if I don't use the SATA adapters, the only cable I have available is a 6-pin (perif) to 4x molex string. And I can only use 2 of those 4 molex for safety, how can I connect the other risers? I have two EVGA 750W G2's. They each have 1 perif and 4 Sata plugs on the back.
So I'm assuming I need a 6-pin sata (that plugs into the PSU) to 6-pin that plugs in the riser, but this is the issue, where on earth are those cables sold. OR I need a 6-pin sata (that plugs into the PSU) to molex, and again, can not find cables for that.
Unless I'm just totally blind.

Sata connectors are rated at no more than 54 watts.
Molex connectors are rated at 132 watts.
Yo are wrong on both accounts.

There is absolutely nothing wrong with sata powered risers, as long as one does not connect more than two risers to single sata cable.
Can you provide a link to an example riser? So many people have said so many opposite things I am totally confused. It sounds like you're saying the sata plug risers are actually worse then the molex ones. Where is everyone getting all these risers and dedicated cables? Or 90% of people are doing it wrong...
It's really quite straightforward:
Sata connectors are rated at no more than 54 watts.
Molex connectors are rated at 132 watts.
I'm not sure what the 6 pin is rated at but I think it's more than the Molex.
Therefore if you have any sata connectors in the cable to your riser, then there is a risk of overloading the connection. It doesn't matter if the sata connector is on the riser or in an adaptor cable. Same problem. Solution: Do not use the ver 7S risers.
Recommended: ver 006C (6 pin) or ver 006 (molex)
Of course lots of people use the sata type 7S and lots use a sata to molex/6 pin adaptor. But the fact is that the connector is only rated for 4.5 amps vs 11 amps for the molex for example. It will still work and most likely it won't get hot and catch fire. But nonetheless it is much more likely to than the others.

Throw away the included sata adaptor.
I would stick with Molex it can have up to 132W or with PCI-E 6Pin. The 6pin can have 75W.
Mobo PCI-E power is 75W.

Just to backup my statements above...
Sata has 3 x 12volt pins each rated for 1.5 amps so total 4.5 amps is 54 watts.
Molex has 1 x 12 volt pin but it's a big-ass pin (compared to sata) and is rated to handle 11 amps (132 watts)
I know the 7c sounds like the latest and greatest but I would strongly advise not using it (assuming it has the sata connector). It will probably work but also probably be carrying more current than it's rated for. High quality connectors will have a larger safety margin but why take the risk?

Ideally you want a single cable with a 6 pin connector going to a 6 pin receptor on the riser, with no adaptors in between. In the real world this is rarely possible.
Best connector is 6pin, closely followed by the 4 pin molex. Not a huge difference really. What you want to avoid as much as possible is powering the risers through a sata connector. That includes those sata adaptors they usually include. The weakest point whether it's on the riser or an adaptor in between will be the sata connector. The latter was never designed to carry as much current as the molex and 6 pin. It will probably work fine but there is a greater likelihood of failure and even fire, especially if the sata is poor quality.
On the rig I'm building, I have 3 cables with 4 molex on each. I will power 6 risers (2 from each cable). I think this is preferable to having a dedicated wire for each one if it means passing through a sata adaptor. Molex and 6 pin connectors are simpler and more robust than the sata and are rated to carry a higher current.
This is why I won't use the 7S risers as they all seem to be sata based.

However, what about the 6-pin riser? Can I use the 6pin-to-SATA cable that was provided and connect it to the 6-pin to 4x SATA cable that comes with my PSU
Not if you enjoy your house.
Not sure I follow you.... I was talking about these, PSU to SATA directly.
Not SATA to Molex or 6pin.
Or are you saying that SATA connector on Riser's PCB is glued and that's not good?

I'm horribly confused about this too.
I have two types of risers, one has 4-molex and one has 6-pin PSU-looking type plug. Both have a sata connector cable. My PSU comes with two types of cables. A perif to 4x molex string and a 6-pin to 4x SATA string.
What exactly am I not supposed to do and what am I supposed to do. From what I've gathered I should use the 6-pin to SATA string to sata cable to molex. And I should use the Perif to 4x molex string connected directly to the riser BUT only two per string of 4.

The risers I have bought about 32 of them from China , all of them come with SATA connectors which I didn't use at all. I only used 4 pin molex cables from the PSU, running a few mining boards with these cables and everything running smoothly. No problems reported until now. I would stick with the molex cables from the PSU. Of course branded PSU-s is the most important thing of a mining board so do not go cheap in this area.
Don't use any sata connector with a molded end on it. Crimp connection only. 
any screens for us...thanks Don't use any sata connector with a molded end on it. Crimp connection only.
What does that mean exactly? I thought PSU SATA to 6-pin SATA risers were the preference over PSU SATA to 4-pin molex risers.
They are the preference, but it still involves SATA. Crimping means that the wires are pressed together very tightly (which is safe), molded would infer there's some kind of glue/paste holding it together, which is dangerous at high temperatures.

Hi,
Can someone tell me are directly SATA powered risers good? Or I should stick with Molex?
Thanks.
