Unless you have an unusual number of drives, lighting, or fans then 750W can easily support your i9–12900K CPU and a 3080 Ti graphics card. Just make sure you have a quality power supply that provides the advertised continuous power rating so your PC gets what it needs when it needs it.

Is 850W enough for 4080 and 12900K?

Can an 850W PSU handle a 4080? Yes, in fact, we'd recommend a PSU of 850W as a minimum to ensure you also have the power you'll need for the best CPUs for the 4080. Anything over 850W will also be helpful to give you the clearance you need (should your system require it).

How many watts does a i9-12900K use?

Intel's Flagship Core i9-12900K Alder Lake CPU Consumes A Whooping 330 Watts Power When Overclocked To 5.2 GHz.

Is the i9-12900K too hot?

My rules are that the processor, while under load, should keep its sustained temperatures below 90 (all temperatures in Celsius). Very short duration spikes up into the 90s are ok, but should not be reaching 100c (the typical Tjmax).

5 Best PSU for Intel Core i9 12900K in 2022

Is 850W PSU enough for i9-12900K?

An 850W PSU for a 4090 and 12900k should be fine assuming you don't heavily overclock your 4090 by raising the power limit - keep it at 100%, which should be 450W for a 4090. The 12900k should be consuming roughly 100W during MSFS use.

Is 850W enough for 7900x?

For mainstream setups with Intel Core i5 or Ryzen 5, the 850W PSU should be suitable for RTX 4090/7900XTX GPUs, while 750W should be powerful enough for RTX 4080 and RX 7900 XT cards.

What is safe voltage for 12900K?

Q: What's the safe CPU voltage for Core i9-12900K? It depends on the CPU cooler you use. We suggest to keep your CPU temperature under 90°C for a 24/7 overclock. With a 360mm AIO cooler, the suggested CPU core voltage is 1.25v~1.30v, depending on the workload.

What is the best voltage for 12900K?

1.375v is fine.

What is the best voltage for i9-12900K?

At full stock settings most of them needs up to 1.5V for light workloads with highest boost. In most games around 1.45V and for full load 1.3-1.38V.

Do I need 850 or 1000 PSU for 4090?

Is 750W enough for 3080 10gb?

NVIDIA recommends the best PSUs to be at least 750W for the RTX 3080, which is where we will focus here.

Is 850 PSU overkill?

1-3 of 3 Answers. You cannot have too strong of a PSU. The PSU is rated at it's maximum draw available, not how much it is constantly putting out. 850W is certainly overkill, but excess is always better with a PSU.

Is 7900X overkill for gaming?

With 12 cores, the Ryzen 9 7900X is overkill for gaming. There is no gaming set that would utilize this amount of cores and power. In fact, games aren't built to be played with a large number of cores and threads, normally this is a single-threaded task that has to be done with a low count of cores.

What PSU do I need for RTX 4090?

A 1000W PSU will be more than enough to power your 4090, which has a recommended power supply of 850W.

What watt is better 12900K or 5900X?

This is what we expected to see, we know the 12900K has a 241W Turbo Boost Power, and thus we are seeing a max here on this motherboard at default settings of 251W of power. Wow, that's a lot, no doubt. The AMD Ryzen 9 5900X only consumes 140W by comparison.

What is power limit 70% 4090?

Setting the power limit to 70% reduces the average boost clock to 2.6GHz, and 2.44GHz at 60%. In a nutshell, if you're looking to maximize the efficiency of your brand-new RTX 4090 without losing any notable performance, then 300-325W is the sweet spot for you.
