Is my PSU powerful enough?

[baldraptor]

Hi I have a Corsair CX-M Series CX550M 550W Semi-Modular PSU which I really dont want to change .
I am looking to spend up to £400 upgrading my graphics card, will the PSU handle a 3060ti/4060ti or a 6700XT ?

Thanks,

My MB is Gigabyte B660M GAMING DDR4 Intel Socket 1700 Motherboard and my CPU is Intel Core i5 12400F Alder Lake-S thanks

Nvidia recommends a minimum power supply wattage of 600W for the RTX 3060 Ti so i would say no but i'm no expert.

650w recommend for most of the above GPU but because your running a low powered CPU you could get away with 550w imo.

It'll probably work.

I would imagine so. Been doing a similar exercise. My Ryzen 7 5700x draws about 65w maximum (undervolted) and the 6700XT can also be undervolted. I imagine you could get away with 160w.

That leaves over 300w for MB, RAM, fans, drives etc. It will probably run over 70% power draw when gaming or rendering but so long as you don't try to push the 12400 ( which I don't think you can overclock anyway) or the GPU, you should be fine.

The large increase in recommended spikes is to take care of transients and that is an unknown factor

Thanks my 12400 is stock and the games I play are Warcraft , Diablo IV at the moment,looking at more graphically demanding games though ,

So in your opinion which card is less of a risk power wise ?

You can get a 6700xt for £330 that leaves you £70 for a new PSU if required , the 4060 ti is around 5% faster on average but cost more.

Either are a good option with your psu

4060 Ti has the lowest power draw, but tbh, if it doesn't work with one card, it probably won't work with the other either. What's your current card? Chances are it already uses similar or more power.

You can get a 6700xt for £330

OCUK have the Sapphire for pre-order @ £300, stock due in two weeks.

I have a 970 at the moment

6700xt is 2.5 to 3 times as fast as 970

 

[baldraptor]

6700xt is 2.5 to 3 times as fast as 970

Is power draw similar for the 970 as it would be for the 6700 Xt or the 3060ti?

In the ballpark. 4060 Ti would be the closest match, the other two are higher. If you wanted them closer, then undervolting is all the rage nowadays.

How do I find what power a card needs rather than manufacturers recommendations for minimum total power ?

What I do is read reviews like this and then confirm with YouTube videos like these:
