News Some RTX 4090 Graphics Cards Recommend a 1200W Power Supply

Too which Asus adds "Oh- and wouldn't you know it! We sell this lovely 1200 watt Thor supply ...."

Reviews are around the corner, and there we can have a better view of how the GPUs behave.

To Hell with that! Let's speculate, panic and cuss right now!

When you add a adapter you have already added a extra potential fail point, when you add length to the cable you change the resistance lowering the power it can provide.

EDIT and most of the PSU and cable mod companies are selling cables for the cards that plug into the 8 pin PSU side and right into the video card.

Good stuff right here.

Ah right, that would increase the length of the wire. Makes sense. Seems like that hasnt stopped people from creating such products lol - https://www.amazon.com/Fasgear-PCI-5-0-Extension-Cable/dp/B0B7MGTY56?th=1

That video was nice BTW. However it doesnt answer 1 question. I believe I came across a link (either wccf or videocardz) where they show current coming from 2 different 8pin PCIe wires were vastly different when they were connected to a 12 pin pcie adapter. Wonder how much damage that would cause. I dont know if that PSU was single or multi rail.

OK but everything I stated or linked is correct.

People think a 6 pin connector can't deliver the power of a 8 pin 100% incorrect. They have the same +12V cables just missing since wires that have nothing to do with that.

For the short adapters it was found out early that they could fail so it was changed to better gauged wires thus eliminating the problem but still adds a extra fail point.

EDIT I think all these cards are 16 pin for about no reason and most are recommending 3X 8 pin for adapters.

The FE PCB is so small, its hard to put 3 or 4 X 8 pin connectors, hence that 12 Pin move.

No crap and it's 16 pin for the high end adapters they use either 3 X8 pin or 4X8pin adapters.
The PSU manufactures some are coming out with the 16 pin plug for the card and 3 or 4 plugs for your power supply on the other end. (also going to be sold by PSU cables aftermarket sellers Like CableMOD

People will buy anything they think looks cool without knowing anything about it's design.
The only real question is the adapter and how it was designed. The first ones didn't use the necessary gauge wire to actually support the watts.
