Question Going to buy 5070ti (eventually) - Need new PSU?

[Crag_Hack]

Hi I am thinking of buying a 5070ti once the prices drop to ~MSRP. I currently have a Corsair HX850 Platinum PSU. I am wondering if I should invest in an ATX 3.0 PSU to accommodate power excursions. From what I read it looks like my old PSU is ATX v 2.4 and its 850W rating might not be able to handle the power spikes from the 5070ti. Anybody agree/disagree?

If it's a good idea to upgrade the PSU, anybody have any recommendations? I assume 850W is a good choice to go with? My favorite go-to brands Asus/Be Quiet!/Corsair only get blue ratings for the ATX 3.0 PSUs in the tier A list at the cultists list. Am I correct in thinking this is because they don't have professional reviews?

Also I currently have an old GSync only monitor so unless AMD has a totally superior GPU compared to the 5070ti then I think the 5070ti is the way to go.

Thanks!

If your psu is out of warranty thena good insurance policy is a new one for that gpu investment.

@GarrettL Thanks will probably do.

I got a HXI 1000 watt from 2016. Zero issues. I just got the native cable. Gaming my whole box pulls 492 watts. So no issues that I have seen. I have had quite a few cards in this machine/power supply zero issues.

the issue is supply getting a card is hard. 9070xt for 599 is a great buy.

@sonofjesse I worry that the HX850 doesn't have the headroom for the spikes since Nvidia says the 5070ti requires at least 750 W. Also I'm kinda sold on Nvidia because of ray tracing and other new techs that the AMD's don't have... at least I know that was the situation a while back.

Unless you are OC'ing or have tons of other peripherals, 750W is the recommended size. In fact if you pullup any PSU calculator they all say 750W. I'm building a new rig and dropping into it a 5070 Ti. I ordered an MSI MAG 750W PSU from Amazon.
