I called Silverstone, and the gentleman was very helpful. He said these cables work and come in a pack of two.so rx 7900 xtx from asus or xfx cant use they have 3x8pin...stupid

The PSU comes with a single cable with 2 - 6+2 connectors on the end. The kit I have above comes 2 cables with a single 6+2 on each end. So technically you could have up to 4, 8 pins with cable kit.ok so on 1 pcie connector we have 2 pieces 6+2 pin and we got another one 1pcie(2x6+2pin)
so actually we have 2 cables and on each 2x8 pin so 4x8 pin all or ....
For most users the ATX 3.0 specs are absolute overkill, and they would prefer a 600W 12vhpwr connector on a 850W PSU. However that does mean the PSU does not meet the full ATX 3.0 specs, and that's a loss marketing might not appreciate.So this 450W limit on 12VHPWR on this an other 850W PSUs... WHY??
The reason behind it lies in the specification requirements that define it. Within the specification for the PSU has to be able to handle 3x this wattage for spikes and transients. ie 1350W! So the PSU Design needs to be able deal with that without without going into OPP mode and shutting down. for 600W it needs to cope with 18000W. which then requires more costly components and invariably is put it into the more costly and often SFX-L 1000W+ models.
However, as pointed out to a PSU designer, this is very easily bypassed by simply tying the 2 active low pins on the side band to ground indicating to the attached card so that 600W power is available and or by simply running from traditional PCI-E adapters with a similar setup for 2 relevant control lines that indicate to the GPU that max power that can be pulled.
So my question is what do people want. Would you like an 850W SFX Platinum PSU with true direct 12VHPWR connection that has the full 600W unlocked? (not an issue for the connector, or cable 16awg) allowing up to x2.25 power spikes/transients before any chance of OPP shutdown? Or play it safe and follow specs.
40 series cards are supposed to have less spiking power load issues and transients that on occasion could trouble some ATX PSU's. So specs were beefed up and cards improved. In a sense allowing the full 600W could be a bit like Over Clocking, there might be the rare occasion that it causes a PSU shutdown if it goes OPP. But the ability remains to be able to switch your GPU down via s/w to 450W if your unlucky. For the most part I suspect it would be fine and dandy.
My personal opinion is that I suspect the specs are a little overkill and air on the side of caution to guaranteed no surprise shutdowns during gaming etc.
Please do let me know your thoughts as I have a decision to make on this matter now.
Thanks

Here's a bit from PCI-SIG on the matter. Worth bearing in mind that PCI-SIG will talk from a perspective that's very much in the interest of its members to help new PSU sales

From an SFF perspective 12VHPWR does represent a nice clean single cable and connector power for GPU
Indeed as far as i know that is the case, but to be honest, on our engineering sample, I've yet to look at the pcb routing for the pinout on the psu connector block. At the moment this has a 12vhwpr connector and 2 PCI-e connectors wtih dual 6+2pin connectors on 2 cable runs, 4 pci-e connectors in total. Which will cover all bases.For most users the ATX 3.0 specs are absolute overkill, and they would prefer a 600W 12vhpwr connector on a 850W PSU. However that does mean the PSU does not meet the full ATX 3.0 specs, and that's a loss marketing might not appreciate.
Personally I prefer not having 12vhpwr on the PSU side at all, just provide a 2 PSU 8 pin to 12vhpwr connector, the other 2 sense lines are unused at the moment anyways.
Some more thoughts as I put my build together:
-The cables for this unit are SO stiff,I thought they were watching Salma Hayek dance in From Dusk til Dawn.
-The cables are closer in length to their SFX cable kit than their stock cables. The 24 pin for example is roughly 25mm longer than the SFX kit.
-There's no straight SATA connectors. They're all 90 degrees. Why. Why?! Swap one of the two cables for one that has straight connectors on it, please, Silverstone.
-There's a floppy connector on the end of the molex 4 pin cable. I'm curious if there's a single device that anyone out there uses this connector for in the day and age. If anyone knows, leave a comment and don't forget to hit the like button and subscribe for any new cont... Oh, I'm not a YouTuber. Nevermind.
Stiff, nasty cables .. wild guess: FSP is the OEM behind, not SeaSonic?
Those remind me the hardest of the FSP 850 Pro I just got (and HATE its awfully rigid, nasty, Capn El-Cheapo cables!).
cu, w0lf.
The OEM is not Enhance but High Power / Sirfa. The details can be seen in the Cybenetics Test Report including noise levels which are impressive for a 850W unit and challenges the great Corsair SF750 Platinum https://www.cybenetics.com/d/cybenetics_fKO.pdf
probably not. neither are on any published 80plus certifications database, although that testing in TW looks through. Also using dual ball fan rather than Fdb, noisier.There have been multiple 850W PSUs suddenly pop up. Anyone know if they're the same manufacturer as Silverstone?

These two seem to be the same OEM manufacturer, but not sure who. They also claim 100% Japanese Capacitors, but I have no idea how legit it is.

No, I haven't, but I'm so tired and have been trying to get this build up and going for weeks so I just slapped in the standard PCIE cable and NVidia adapter and am calling it a day.Have you tried grounding the 2 sense wires?

PCI-SIG does not care about PSU vendors. They make the protocol specs and they mostly represent CPU vendors and add-in card makers and such.So this 450W limit on 12VHPWR on this an other 850W PSUs... WHY??
The reason behind it lies in the specification requirements that define it. Within the specification for the PSU has to be able to handle 3x this wattage for spikes and transients. ie 1350W!

I mean, the only real downside I've found is the stiff ass cables. It's 2022, these shouldn't even exist, especially in a unit that's (now) going for like $280.Too many compromises in this unit. Otherwise, good quality and compact, would certainly need custom cabling. Hopefully, they improve it a lot in version 2.0.
