What power supply to choose for a 6700 XT (gaming use)

Hello,
I’m changing my GPU to a 6700 XT and currently have a 650W power supply. Some say 650W is enough, while others recommend upgrading to 850W. So who should I listen to? I need to change my power supply anyway to switch to a modular one for practicality with the 500DX case, and also because I don’t have the proper cables for powering the GPU.
My CPU is a 5700X with 16 GB of 3200MHz RAM, I have 5 fans – 2 for the CPU cooler and 3 others for ventilation, plus 1 more that I plan to add at the front. I also have 2 internal hard drives and one M.2, as well as an external hard drive.
Additionally, I’ve heard about the PCIe 5.0 standard, but I’m currently on 4.0 (AM4). Can I use a PCIe 5.0 power supply with this setup? As for the brand, I’m initially thinking of MSI.
Also, I don’t plan on doing any overclocking.
Sorry if this is not the right category, I hesitated between two :/

Hey
Both are fine as long as you're comparing "outdated" evaluations; no one plans to overclock, in 2023 that doesn't work for everyone, especially players. Graphics card processors and programs don't operate like they used to, you can't say that anymore.
Don't plan on overclocking: we see players coming back after their purchase, anyway with the configuration if you're playing the games they will eventually set no limit, maximum power everywhere. And anyway, you can put a 1300W power supply but it won't consume more than what the PC draws, and the best efficiency is around 50% of the power. And when you have a 10-year warranty, what do you think of my little calculation today? I'm still using my power supply from 10 years ago; do you think I planned for 2023 prices? No, but I did well.
(850W gives you the margin of error to avoid very brief voltage anomalies that might cause crashes; there are enough other causes for crashes with games better to eliminate that one right away without paying for two power supplies. In doubt, you end up sticking with the 850W for 80% of players [and it's always players, and always in doubt without relying on measurements or calculations], and you don't recalculate every time you plug in a USB. On paper, you always list a power supply that the PC will never use the big number for)

A hello, an answer, a thank you are always appreciated.
For a RX 6700 XT, AMD does recommend a power supply of 650W. But since you want to change the power supply, go for a 750W one to have some headroom, unless you plan to change to a GPU that consumes a lot in the future, in which case an 850W one could be an option.
"Additionally, I’ve heard about the PCIe 5.0 standard and I'm currently on 4.0 (AM4), can I use a PCIe 5.0 power supply with this setup?"
The PCI-Express standard is backward compatible. So when components with the PCIe 5.0 standard come out, it won't be an issue with your motherboard.
As for brands, it's better to choose recognized ones that specialize in power supplies, such as Seasonic, Corsair, be quiet, etc. FSP is also making a comeback.
Alright, I'm going to go with an 850 so I can be safe; it should avoid any risk of "malfunction," let's say ^^ and for future peace of mind, I don't intend to aim for a high-end card, I'm always looking at GPUs in the 300/400€ range.
MSI is good too, right @epango?
I see this one that looks quite interesting https://www.amazon.fr/MSI-dalimentation-Gestion-enti%C3%A8rement-modulaire/dp/B0B4345YV7/ref=sr_1_3?__mk_fr_FR=%C3%85M%C3%85%C5%BD%C3%95%C3%91&crid=1OVVC4I9QXJUV&keywords=alimentation+pc+msi+PCIE+5&qid=1689242148&s=computers&sprefix=alimentation+pc+msi+pcie+5%2Ccomputers%2C71&sr=1-3
hi Lethsnar
if you have a 650W 80+ Bronze, there's no need to change it
in games, the RX 6700 XT consumes 190 watts = https://jide.fr/test-amd-radeon-rx-6700-xt/
save your money for something that will be more useful
see you
It's not certified, the one I have https://www.amazon.fr/Corsair-Alimentation-TX650W-CMPSU-650TX-Supply/dp/B07H5NZ9KN and the wiring is not compatible with the GPU I have, it's a 6-pin power cable...
it's a Corsair
this range was 80+ certified = https://www.corsair.com/fr/fr/p/psu/cmpsu-650tx/enthusiast-series-tx650-80-plus-certified-power-supply-cmpsu-650tx
and besides, it's not a no-name
and with your setup, you'll never reach 550 watts
"Ok, so I'm going to go with an 850 then to be safe; that should avoid any risk of 'malfunction.'
Maybe we misunderstood each other. I meant that you don’t need a power supply of 850W unless you plan to upgrade to a GPU like an NVIDIA RTX4090 soon. For your current GPU, 750W is sufficient. There's no point in having excess power.
As for the power supply brands, I see that brands like MSI, ASUS, Gigabyte, ... and even Aerocool have power supplies. What I don’t know yet is whether they design their own power supplies or are just rebranders. If they are rebranders, who manufactures their power supplies. That's why I prefer to recommend the brands I've mentioned above for the time being.
PS: on your link, there doesn’t seem to be any certification indication for the Corsair power supply. But it appears that it is 80+ Bronze certified.
Sorry for the delayed response. I was thinking about an 850W to allow for more flexibility in choices for the future in case the consumption of GPUs increases.
What happens if the power supply is too powerful otherwise?
Exactly.
And:
the consumption of the new graphics cards is generally decreasing
Well, not really....it's the opposite, just look at the issues with the new connectors of the rtx 4xxx......
it's not the same power at all
you need to take the replacement of the original one
if we're talking about a GTX 1030 and its replacement, the GTX 1630, the latter consumes less
if you talk about the GTX 1030 and you take the replacement of the RTX 4060, for sure it will consume more
and the replacement of the RTX 4060 will consume less than this one
.
I'm wondering how some people think and analyze
.
flo, you're not the only one thinking incorrectly
We must also stop misleading internet users; high-end graphics cards are increasingly drawing power, and coupled with a high-end processor, it is now necessary to exceed 1000W in power supply for it to hold up.
This is a fact.
Who talked about low-end cards?????????? a 1030.........seriously............
It's now been almost two years since the new connector profiles for the 4xxx cards arrived (AMD will be there too): PCIe 5 graphics cards can draw up to 600 W via a 12VHPWR connector - Les Numériques (lesnumeriques.com)
--
This same connector is facing issues today because it melts as high-end NVIDIA cards draw so much wattage and current. A problem known for at least a year.
This has never happened in the past where the standard had to evolve so quickly, and power supplies as well. The reason is the power of the cards!
Soon we will see a new connector arriving to (already) replace the 12VHPWR because it can no longer handle the power. The 12VHPWR connector will soon be replaced by the 12V-2x6 connector (cowcotland.com)
As a reminder, a RTX 4090 exceeds 500W in testing.
And yet another article to hammer home the point for the skeptics of the before/after....
I think that should be enough now, right?
Well actually, I'm currently changing my graphics card, I went from a 1060 to a 6700xt and I need to change the current power supply because I don't have the right connection for this graphics card, plus I'm looking for a modular power supply because a non-modular one is a pain, especially in a case like this.
Indeed, if you think about getting a GPU that consumes a lot, like the RTX 4090/Ti, in the not-too-distant future, you can already opt for an 850W power supply. The resulting relative excess consumption will be insignificant.
Interestingly, at Corsair, among the already released ATX 3.0 power supplies, the 750W models are more expensive than the 850W ones.
PS. The new GPUs, at least those from NVIDIA, do not tend to consume less. Hence the necessity for a new connector, the PCIe 5.0 12VHPWR that can deliver up to 600W.
old bulky bison,
I didn't quite understand your intervention. His current CPU is not the most powerful. However, nothing prevents him from putting in an 850W power supply and an RTX4090/Ti, if he wants to. The only thing is that, with his current CPU, an RTX4090/Ti wouldn't unleash its full potential. But there is no incompatibility.
