[SOLVED] Reducing the TDP/Power Consumption of GPU ?

[YungPadawan]

So basically what i want to know is 'which is more effective in reducing the power consumption/TDP of a GPU(r9 290(275W)), i stay in West Africa and it's pretty hot here and that GPU consumes a lot of power and will produce quite some heat/noise(me and my bro sleep in the same room so i want to reduce the heat/noise and apart from that i'm also curious to see how low in TDP i can get it to stay, i don't care about having maximum performance), i don't have the GPU yet but its coming to me before the end of the month, so i want to reduce its power consumption and i know that i can use MSI Afterburner to reduce the power limit and there's also a voltage meter so "Which will be more effective in reducing it's power consumption and what should i watch out for?" i watched a video where a 1650s was reduced to 60% power limit and there was like less than 10fps loss and also one where a 780 was reduced to about 60 to 70 % power limit and there was hardly any fps loss but the power draw of the entire system dropped like about 100W

You can try “undervolting”, just Google guides. You can also limit your FPS, for example if you have a 60Hz monitor but the gpu can produce 100fps you are not getting too much benefit from the extra 40fps. Using an FPS limiter to 58/59/60 FPS (need to experiment) you would significantly reduce the gpu workload.

true, my monitor is only 60hz, it's an old monitor too, will upgrade in the future, its 900p 60hz 🙁

but undervolting will reduce its power draw but not limit it's max power draw limit(275W)?

While it does not directly limit the max power limit it will indirectly reduce the power used. For a certain gpu speed the gpu will use less voltage and therefore power. This is often done for laptop gpu’s to reduce the power and thermals.

As long as you are happy with 60Hz. I’ve been a pc gamer (casual) for over 20 years and only upgraded to 144Hz about 2 years ago. You can still have a lot of fun at 60Hz although I will admit I would find it hard to go back now.

It should still result in lower power draw; the max limit is just that, a maximum limit. If the actual power draw is lower, then the 275W value is irrelevant. Your car might have ,say, a 150mph limit from the factory but if you never even drive past 100mph then that limit is irrelevant in practice, for an analogy.

Keep in mind power= voltage x current. Undervolt until you get stable performance at the level you wanted it to be.

That said, I imagine you can get good decrease in power seeing you're using an RX 570 for sub 1080p and 60Hz. Easy peasy to run the vast majority of games in that scenario. Had a 580 connected to 900p 60Hz TV and runs everything I throw at it easily (except badly optimized games, but that's beside the point).

ok thanks
