be quiet! Introduces 12VHPWR Adapter Cable for RTX 4090 and RTX 4080 Graphics Cards

The Silverstone cable is 12 pin. It's not 12+4. It's not even the same plug.

They have their new power supply that comes with a proper cable https://www.silverstonetek.com/en/product/info/power-supplies/HELA850RPlatinum/ so I'm guessing you need to wait a bit for them to make a different one for older units.

They definitely did not have any photos that show the other side, so it was hard to see for sure. Thanks.

According to Silverstone's documentation for the ST1500-TI (Silverstone 1500W Titanium), pushing more than 150W through any one of the PSU PCIe 8pin cables voids your warranty. So to get the full 600W you would need a 4x1 power cable. ( (4) 8 Pin PCIe connectors, and (1) 12vhpwr connector )

It would seem to me that using this cable might void the warranties on many power supplies.

* Power supply connector overuse definition
A single PCIe 8pin cable and connector’s maximum current rating is 12.5A, which is 150W (+12V x 12.5A). So SilverStone’s warranty will not cover damages or malfunction resulting from the use of a graphics card or expansion card with a single PCIe 8pin connector that exceeds standard 225W total power draw (150W from PCIe 8pin connector + 75W from PCIe motherboard slot). Similarly, a graphics card or expansion card with dual PCIe 8pin connectors that exceed 375W total power draw (300W from two PCIe 8pin connectors + 75W from PCIe motherboard slot) will also not be covered under warranty.

This one is a weird unit, doesn't include any daisy chained cables, so it kind of makes sense that it's limited to 150w per connector. Corsair and Evga units for example have 8 pin connectors power supply side, but they use daisy chained cables so 300w is fine.

I'm getting a distinct impression that the documented electrical specifications for the standard are 150 W, and the test specification for the connecter is 300 W, so some companies choose the lower of the two competing specs, and some companies choose the tested physical maximum.

To me, it seems like total Chaos as these new GPUs are pulling down so many Watts that these decades-old discrepancies are now being tested, and flushed out.

It also seems like PSU manufacturers are only partially motivated to release optimal cables for old supplies and have an anti-pattern benefit to release new PSUs first.

The more interesting thing is the official SilverStone cable they've launched to fulfil the 4000 series 12pin ask is only 2x8 pin at the PSU end.

So SilverStone are effectively selling a cable for use with their own products that appears, given your statements around the 1500W model, to invalidate the warranty?
