I've never used an add2PSU on my own rigs (though the rig I consulted on for someone else used one) so I can't really speak to those.

make sure the risers are isolated from the case.
Every riser I've seen to date comes with a fairly thick "rubbery pad" on the bottom that works as an insulator, and isolated screwholes for mounting.
The very first riser I bought a ver 006C didnt come with insulation.
I had to cutout the black foam packaging in my gpu box to fit under the riser and then I zip tied it.
I recently bought an Add2psu and it was missing the bottom insulation also.
If I could find a GOOD MOLEX riser, I'd go with it - but so far no luck.
The all-in-one risers I've gotten from COBOC via Newegg have been hassle-free.
The Mintcell all-in-one risers worked, but the USB cable was iffy and had to be replaced to work well on one.

USB Cables I received were rigid white ones, and I was having problems with more than a few of them. Waiting on new longer cables now but so far that's what seems to be the main issue. I do like them so far though.

Thanks.
I'm also wondering if it makes sense to buy an all-in-one riser (with all 3 power sockets SATA/Molex/6Pin), instead of a single 6PIN riser board?
The only issue is the location of 6pin socket of all-in-one riser is in the middle right next to the pcie slot. The single purpose 6pin riser boards have them in the back.
I will have the gpu cards line up parallel to each other, so if the 6pin socket must go in between the cards there will be some air flow issues? much rather have them in the back so the power cable doesnt have to go between the gpu cards which could get pretty hot?

Well I don't think some of those operating miners miss it out isolating the risers from the case. Its an important options to do since that the hardware is very sensitive to heat and dust being accumulated during the running conditions. Proper handling is one of the good ways to observe specially the investments in mining harware is costly.

The case of the PS is isolated - doesn't matter if you let it ground or not.
You don't mount DIRECTLY to the aluminum as such, you use spacers - both MB and riser cards have "isolated" mounting holes so you can get away with using brass or steel spacers.
Iron is close on conductivity to aluminum.
Both are somewhat inferior to copper silver and gold but ALL of them are "conductors" and conduct electricity well.
Many high-tension power lines back in the past used an iron core with copper electroplated to that core.
Today the core is usually aluminum due to it being lighter while still being stronger than copper.
Riser cards ARE fairly standardized - that's why you see so many folks offering the "same version" risers.
I have no clue who originates the design for each version.

I got an open frame steel case that mounts everything including the power supply. Everything except for the PSU will be mounted with either spacer or rubber pad (riser boards).
Am I supposed to mount the psu first and ground it? It looks like PSU is the only component that directly touch the steel frame.

It never hurts to use TOO BIG of a wire, except where cost is a factor.
Runs cooler, less IIR losses (though usually not a BIG difference on those factors for only going "one step" bigger).

Cost is certainly a factor ... lol
but I definitely want to be on the safe side.
the more info I dig the more question arise out of them...
It seems to me most of the parts are standard manufacturing, including motherboards, and the only non standard equipments are the riser boards and custom chasis. Any reason why motherboard makers wont release standard x1 - x16 boards that are tested safe to use with PSUs ?
I feel folks would pay a little premium for those parts if they are standardized?
As for chasis/mounting frames, if anyone has a recommendation i'd greatly appreciate it.
I read some debates on wood vs metal, and am somewhat leaning towards metal frames made from iron....
some folks recommend aluminium, but isnt aluminum too good of a conductor to mount electronics on? last I checked, iron is much less conductive?

It's about the wiring, not the PCI-E spec itself.
I don't think they anticipated folks using wiring runs long enough for IIR losses to cause issues, or enough losses to cause noticeable voltage drop to the connector.

thanks for the response...
Would using or mixing 16AWG vs 18AWG pcie power cables make a big difference?
I'm using 18AWG cables from the PSU but need to add an extension cable so I can use the same power cable to plug into both the gpu and riser board (6pin), the original psu cable comes with two end points but is only long enough to reach either the gpu or riser but not both. The only extensions I could find right now are 16AWG cables. Any issues that may stem from attaching 16AWG extension cable(connect to riser board) to original 18AWG cable from psu?
Is the bottom of it "bulged out" so that it CAN'T seat? If so, don't even THINK about trying it - it shorted out or something at some point and seems to be leaking as well.
The only issue I have with the Mintcell risers to date is that once in a while the USB cable itself is iffy - but they're standard cables and cheap/easy to replace when that happens.
How does one determine the USB cable is iffy? I've had a few problems with Mintcell risers where the rig would freeze/lose GPU connection while mining - I just assumed they were beyond repair and replaced them. What are the signs of bad USB cables?
Also, check this out... Mintcell risers I got last week:

Swap the cable.
Trivial to troubleshoot if it's the cable that way.
Good call on that riser, it's OBVIOUSLY messed up.
Cap didn't get installed correctly and/or failed.
The other one I can't say for sure - but it kinda looks like C13 should be there, and not sure if the 2 resistors under the right end of the PCI-E bus connector are needed if you are powering for MOLEX or not (the other regulator "missing" parts are probably for +5VDC supply and not needed with a MOLEX since the PS supplies +5VDC on a MOLEX connector).

I have 4 rigs each running 8 GPU's a piece running these: https://www.amazon.com/gp/product/B074NX9B8V
They work well and I have 0 issues with them

I use these as well. No issues.

This one boots but makes the rig crash after 15min - 1 hour of mining. Are those capacitors supposed to be perfectly lined up?
