videocardz NVIDIA GeForce RTX 4090-class GPU with 600W TGP has reportedly been confirmed

There is yet another report that next-gen NVIDIA series will require lots of power.

 

Granted, we are only talking about the flagship models for now, but 600W graphics cards are still something that many of us simply cannot comprehend. The latest tweet from a reliable NVIDIA leaker kopite7kimi appears to confirm that next-gen XX90 class GPU is to feature TGP (total graphics power) of 600W.

With utilities costs going up, we won't be able to afford to run them...let alone buy them lol.

Anyone have time to explain the steps required to correctly (if possible) run dual PSUs in a single system (specifically a single motherboard, not one of the "2 systems in one box" builds)?  Say, GPU on its own dedicated PSU and the rest of the system on the "primary" PSU.  I can envision splitting the output from the "power on/reset/etc." buttons no problem, but do we run into issues with "desynchronized" signals from the two PSUs?  I wouldn't think so but can't be 100% sure by force of imagination alone.

Yeah, apart from running costs, some GPU vendors is also a bit tone deaf re. the times. Even my 3090 Strix OC pulled over 500W straight out of the box already (before custom vbios). I haven't bought a PSU with less than 1300W for my systems for a decade, and sill live of a pile of those which used to do Quad-SLI for HWBot in multi-format way back. I can only imagine 2x of the upcoming 4090 KPEs slurping the juice; even the rumoured KPE 3090 Ti is apparently > 600W w/ full PL on its own...

 

Where I live, 98% of our electricity comes from hydro, and electricity costs are 'reasonable' - but costs are certainly not going down.

The 2x PSU's run independently from each other.  The only signal they share is On/Off when the system is turning on and off. I had used dual PSU setups for years back in the day and nothing has really changed, all you need in the 24PIN Splitter cable.

You will note that the spit off 24pin connector only has two actual cables going into it, that is because the second PSU as I mentioned just needs the On/Off signals. 

 

I used to run my SLI setup off the second PSU and my primary took care of the system itself and overclocking.

I've been using the Add2PSU boards for a long time. https://www.amazon.com/Multiple-Adapter-Connector-Genetek-Electric/dp/B0711WX9MC

 

Below is the small add-on-board in my workstation. The top 1000W PSU powers two GPUs and the bottom 1300W PSU powers the rest of the system.  Absolutely zero issues.

I normally use either 2x Antec 1300W HPC which have a proprietary OClink to each other (for an easy 2600W), or heavy-gage multi- PSU cable trees - like the ones below but better wiring...probably what you need if you want to run dual upcoming dual 4090 Tis

Why do I see a return of these horrible things in the near future?

It's actually a question that's been asked many times over the years. Using linkable power supplies like J7SC mentions above will work, where that possibility exists. There's also what follows, which provides a bit more clarification about using dual psus to boost available power (see the answers in the linked content):  

 

Using multiple power supplies in one PC. 

 

Also see dual pc power supplies avoiding ground loops for its SERP (About 106,000,000 results).

 

Ground loops can actually cause damage if not properly mitigated.
