Gonna replace a couple i suspect might be causing slightly slower hash rates than other identical cards. Figure i might as well do them all.
Prefer molex. Unless there is a molex to 6pin adapter that doesn't need 2 molex connectors as input.

Persoanlly i go for the ones with FOUR capacitors on. No particular brand or make as they are all basically the same. They all do a range of different connectors.

If you run into problems with any of your risers, I've found that in probably 99% of the cases I've had problems it was their cheap USB cable, not the riser or the PCI connector. Although I've phased out my riser use, towards the end I just bought 1.5ft USB cables for all my risers and swapped them regardless if I had problems or not. Saved me a bunch of hassle in the long run...

Coboc or Mintcell "version 8" with the 3 power connector option is my preference at this time, as I've yet to find a good MOLEX only riser that I don't have to wait a month for China shipment for.
Had a batch of those Weitec (probably misspelled) same-type risers that 3 of 6 were BAD out of - definitely avoid.

I have considered doing this actually. Hard to tell what USB cables are quality or just the same garbage you already have. What are you using now if not risers? Onda boards? Sell me one? hehe

Generally 6-pin risers are considered safer than molex. I've heard horror stories of people's rigs blowing up or burning down because of bad molex connections.
If you are looking to squeeze every bit of efficiency and profitability from your rigs, then I highly recommend you also get risers that are version 008. It is said that these versions are more power efficient than others. I can't remember where i got the tip from but I believe its in one of the topics here in this forum.

Bad connections can happen with ANY connector type, especially if you plug and unplug the connector a lot. Molex one downside is that it can be a bit of a pain sometimes to get the pins aligned properly when you push the connector into the socket - if you do that with care you should never have an issue.
One thing I HAVE noticed is that a lot of riser makers seem to "cheap out" on the soldering job, I've seen a few MOLEX risers where the MOLEX connector wasn't soldered AT ALL, just a press fit - which is a DEFINITE recipie for failure on a frequent basis.
Version 6 should be the MINIMUM riser generation to consider - not that they're more efficient, but they're more RELIABLE than anything older.

These are the ones I always used: http://amzn.to/2BMxYAtThey aren't the cheapest, but they're not bad and super reliable - I don't think I had a single one not work. For my last build 3ft was the ideal length, but they sell smaller ones that might be better for most people. I've tried all those - Colorful, Onda, etc... TBH I love them all, you really can't go wrong with any of them, even some of the weaker ones.

It gave me all sorts of issues where the video card wouldn't even show up at all, and some would. The ones that did, when I went to go mine, it would lock up the system. I switched to the shorter included mintcell cables and it solved those problems. I also found a website that shows where longer USB cables puts strain on the system itself killing speeds it can transfer and that 1.5ft was pretty much the longest you could use. So I am curious as to how you got 3ft to work reliably.

this is correct..I have molex risers version 3 from 2013, mining for 4 years already. If you run into problems with any of your risers, I've found that in probably 99% of the cases I've had problems it was their cheap USB cable, not the riser or the PCI connector. Although I've phased out my riser use, towards the end I just bought 1.5ft USB cables for all my risers and swapped them regardless if I had problems or not.

not just the usb connectors sometimes there are white stuff under the riser board...that white stuff is something that is left after soldering, this can conduct electricity and cause problems, people should check and scrub them off before using just to make sure.

No opinion - but I'll point out that Newegg carries 6-packs of the Mintcell version of those for $7 or $8 more, shipped from the USA instead of shipped from China.

So I am curious as to how you got 3ft to work reliably.
I think it depends on what you're trying to do - generally speaking mining doesn't put any real stress on the PCI bus in terms of bandwidth, and typically bandwidth (speed) is what you're going to loose over longer cable runs. Probably the two biggest issues you run into with cable length is signal loss and interference - so you can at least be relatively sure that a higher quality cable is going to have better insulation. Whether or not it's going to help in the signal loss department is a bit more iffy. I've literally built 100's of rigs using those exact 3ft'ers I've linked to without any issues (you may have seen my custom miner enclosures, they all use these cables). Personally I hate this design of risers - it does just about everything wrong in my opinion. First, the molex and PCIe connectors are located such that they almost always interfere with the card or sit right up against the heatsink of the card, which it terrible in my opinion - personally I only buy the ones with the 6-pin PCIe connector for power, and then just use an adapter if I need to get it from something else. The slot connector has a right-angle plug on it, so on smaller builds with just a couple cards on a traditional motherboard it won't be an issue - but on a larger board like the Asus B250 Mining Expert you can't use these because the small slots all overlap - only the typical upright ones work. Beyond that it's fine.

Id buy the 6pin riser but its hard to find inexpensive single molex to 6pin. Kinda weird that there are so many single sata to 6pin abut hardly any single molex. They are all dual molex. :/

There IS such a thing, but they're not common. Since you probably should only be running 1 riser from a molex string though, it's really not hard to plug both molex connectors into that one string. EVGA in specific has stated on their web site in the forums that their "peripheral" connections are only rated 75 watts per STRING. I've NEVER seen interference with the MOLEX or PCI-E connectors on the "3 way cards" with a backplate GPU - though I can see a possibility of the "latch" on the PCI-E power cable being a tight fit. If I'm going to use PCI-E power to the riser though, I just go with a straight PCI-E riser not a 3-way. MY main issue is they put the dangerous and worthless SATA power connector on the end of the card, where it's easier to route the riser power to - I'd rather see the MOLEX connector there. The right-angle adapter IS a bit annoying, but there are some folks that offer the traditional "straight out" adapter with those risers. I CAN see them being an issue on the B250 Mining Expert for all but ONE row of 1x slots as you point out, but they shouldn't be a significant issue on any other motherboard I am aware of.

Thanks These are shit ones i am using now. https://i.imgur.com/Ruzyv65.jpg I am running 2 per Molex chain though. Figure its fine for 1060s at 80% So are you saying i can mod dual molex to 6pin to single molex to 6pin? I have a tone of them. That would make buying risers MUCH easier. I can only find single molex to 6pin, for a reasonable price, from China.. Dont want to wait that long. :/

Had a batch of those Weitec (probably misspelled) same-type risers that 3 of 6 were BAD out of - definitely avoid.
Have you got a picture of these risers fitted with a gpu? It looks really tight for a power connector down that side.
