Hopefully the RTX 40 series is looking at lower power usage.

Because at 300-400 watts, this is basically mandatory unless you like the Summer heat.

For context I own an RTX 3090 (thanks to LTT during when they were selling GPU's) and everyone talks about how hot it gets. Though nobody really talked about where the heat goes. Obviously outside the system and into your room at roughly 115F / 46C under full load.
I wasn't going to be running the A/C to combat the heat of this so the only realistic way to deal with it was to move it somewhere else. And that's where the idea for this contraption came in.
I'm using 'heavy duty' cardboard to try to insulate the heat since I don't want it to radiate too much. Connected a 6' duct with an in-line fan and backdraft damper and am venting it out my window that has a portable A/C window panel attached to it. There's also a bug screen sandwiched at the end to prevent some insects from trying to crawl their way in.
The exact shopping list apart from the super glue, tape, and duct tape I used are...

It's extremely efficient and could be even better if I put on the duct insulation I got but I don't have the tools to cut fiberglass at the moment.

I had an idea to water cool the CPU and GPU and send the tubes through the floor to radiators in the basement, and dump the heat down there. If you have a heat pump water heater then you could essentially then use that heat for your hot water.

Sadly, at least with current tech.
and AFAIK.
More performance needs more juice.

Maybe in the near future we will need to power a GPU using a secondary PSU.
Or a truck battery.

I will not keep buying pc components if all they do is increase the power requirements.  It's bad enough as it is, but they might be staging it that way so they can come up with a "new" series that will be more efficient for similar performance.

ATI and NVIDIA have been briefing power supply manufacturers in Taiwan recently about what to expect for next year’s R600 and G80 GPUs.  Both GPUs will be introduced in late 2006 or early 2007, and while we don’t know the specifications of the new cores we do know that they will be extremely power hungry.  The new GPUs will range in power consumption from 130W up to 300W per card

 

You will see both higher wattage PSUs (1000 - 1200W) as well as secondary units specifically for graphics cards.  One configuration we’ve seen is a standard PSU mounted in your case for your motherboard, CPU and drives, running alongside a secondary PSU installed in a 5.25” drive bay.  The secondary PSU would then be used to power your graphics cards. 

 

History repeats itself...

3900x | 32GB RAM | RTX 2080

1.5TB Optane P4800X | 1 TB Adata XPG Pro | 2TB Micron 1100 SSD
QN90A | Emotiva B1+, ELAC OW4.2, PB12-NSD, HD800

This is a very misinformed statement, every generation you get more efficiency because for example the XX60 card will perform similarly to the old XX80 product and use less power than it did.

 

It has ALWAYS been about performance with top end gaming GPUs. Top end GPUs will always be designed to use as much power as they possibly can to get the maximum level of performance from the chip and lead the generation in the only metric that really matters, raw performance.

 

Someone who is in a position in life to spend large sums of money on a high end gaming PC is usually one who doesn't mind spending on the running costs with his electricity bill. Matter of fact ever hear of SLI? Gamers were not worried about stacking multiple power guzzling GPUs in their machines in the name of increased performance! Now we are in a golden age where there are single GPUs with massive performance available on tap with none of the disadvantages of SLI.

 

With RTX GPUs, they use a lot of power and the level of performance is extremely high. Crypto miners also don't worry about the power draw as long as the performance is good enough to make it efficient after you do the monster math.

It's not the cost it's the power draw.  

 

I'm not running a seperate circuit for a gaming PC.

i'm thinking about breakers for the first time for a gpu

 

pretty sure the power curve is efficient when compared to pascal even at 450-600w, but it's for sure in the exponential part of the curve for ampere or lovelace above 300w

Ah, the joys of 120v mains.

 

Here in the UK I can get just under 3kW out of 1 socket.

Ya, there is a slight advantage to having 240v outlets.  You can theoretically milk 1800watts out of a 120v circuit here and in my case, I've got one circuit for the PC, monitor, some lights, amp, speakers, tv and console.  They're not running all at once or at full power but it's nice to have the headroom.

  I'm going to max out my pc to about 850-1000w  including the monitor and I would hope to have performance gains in newer tech to cut the usage, not just having more fps for more power.  The trend should be toward efficiency, it's better for everyone. 

This 40 series seems like some real bullshit, it's not like the 30 series is cheap and plentiful and everyone is bored with them.

Agreed... its getting out of hand.  I didn't do enough research when I got my 3080 which required a new PSU for the 3rd 8pin and wattage increase and went to a 1000w... I refuse to buy a bigger PSU at this point lol... they need to work on their effiency or something if they are going to get to the point where 1000w is the new 650w today.  Between my PC, 3 monitors, Speakers, NAS on my desk... im not running a different circuit just for the PC alone hahaha...
