In this guide, we’ll help you find the best power supply for Intel 13th Gen processors so your PC upgrade won’t be hampered by power limitations. Without further ado, let’s dive into our article on the best PSU for Intel 13th Gen CPUs.
The 13th Gen Intel processors are public and the performance gains with this generation are certainly quite impressive. Intel decided to add more cores, add higher boost clocks and even increase the L3 cache. All this results in a performance boost that is significant for both gaming and productivity.

However, there is a certain trend with recent hardware launches. As performance improves, power and thermal efficiency take a bit of a hit. This applies to both AMD and Intel, and even to a large extent to Nvidia. People upgrading this generation will probably need new PSUs.
That’s why we try to help you find the best power supply for Intel 13th generation processors. Before we dive into our top picks, there are a few things to keep in mind before going for the upgrade.

SeaSonic is perhaps the most reliable brand out there when it comes to PSUs. The Focus GX1000W is an excellent premium power supply for 13th generation processors.
EVGA SuperNOVA 850 GA
EVGA’s SuperNova 850GA is an excellent high-end power supply that is also great for the price. It is one of the best choices for mid to high end gaming rigs.
Corsair RM850X 2021
The Corsair RM850X is arguably the best PSU you can buy from Corsair. This 80+ Gold PSU should have no problem keeping up for years to come.
Power requirements and TDP for Intel 13th generation processors
There are a total of six SKUs for the 13th generation Raptor Lake lineup. Each processor consumes slightly more power than its previous-generation counterparts. Of course, the TDP only goes up if you go from something like the i5 13600K to the i9 13900K.
Let’s look at the TDP for each of these processors.
Intel 13th Generation Core i9 Power Consumption
- Intel core i9-13900K | (Base) 125W (Boost) 253W
- Intel core i9-13900KF | (Base) 125W (Boost) 253W
Intel 13th Generation Core i7 Power Consumption
- Intel core i7-13700K | (Base) 125W (Boost) 253W
- Intel core i7-13700KF | (Base) 125W (Boost) 253W
Intel 13th Generation Core i5 Power Consumption
- Intel core i5-13600K | (Base) 125W (Boost) 181W
- Intel core i5-13600KF | (Base) 125W (Boost) 181W
So if you are upgrading from a processor that is a few generations old, these numbers will seem quite high to you. Unfortunately, that has now become the norm, which is why you probably need a new PSU. But what is the best PSU for Intel 13th Gen CPUs?
Do you need a new power supply for Intel 13th generation?
The answer to this depends on whether your power supply has enough wattage for new hardware. Let’s not forget that you have to consider the graphics card and other components. We will look at an example to further illustrate this point.
Say you just bought a brand new Core i5 13600K. If you want to pair it with something like a 4080, you’re already looking at power consumption of around 500W. That is without taking into account the rest of the components. You always want to have a little headroom before you upgrade.

So if you’re building a new PC or upgrading to new hardware, you’ll probably need a new high-capacity power supply. These days, 750W is the sweet spot, but if you can go for 850, that’s even better for future proofing.
In short, you need a new power supply for Intel 13th Gen if you combine it with a powerful GPU that has recently been launched. However, this may not be true if you opt for a GPU that consumes less power. Newegg’s nutrition calculator is a great tool for figuring this out.
Remember that GPUs have a big influence on the PSU you need
Of course, which PSU you need depends on the CPU you want to buy. The 13900K consumes a lot more power than the 13600K, which means you need a better PSU to support it. That said, GPU has a huge influence on the PSU you need. Make sure you have all your components lined up before buying a power supply.
Best Power Supply for Intel 13th Generation CPUs – Overview
Now that that’s all behind us, let’s finally take a look at the best power supply for Intel 13th Gen CPUs.
SeaSonic Focus GX1000
Seasonal FOCUS GX-1000

Advantages
- Silent operation
- Generous 10-year warranty
- Enough power for any build
- Excellent reliability
cons
- Pricey for mid-range builds
Wattage: 1000W | Rating: 80+ Gold | Design: Fully modular | Form Factor: ATX
The Seasonic Focus GX1000 is the best power supply for Intel 13th Gen processors if you’re building a high-end rig. Sure, 1000W might be a bit over the top for most gamers, but if you’re putting together an ultra-premium rig then you’ll want to buy the best power supply possible.
Seasonic also has the Prime TX-1000 PSU. It is also a 1000W but has an 80+ Titanium rating. However, it costs almost twice as much as this one. Since the Focus GX line is great on its own, there’s no real reason to go for the TX PSUs.
Furthermore, this PSU has an 80+ Gold rating, which is the best you can get in this price range. It is fully modular, features great fan control and has excellent acoustics. You will not find any complaints in terms of thermals and noise.
Considering that SeaSonic gives you a 10-year warranty, this was an easy choice for us.
EVGA SuperNova 850 GA

EVGA SuperNOVA 850 GA

Advantages
- Completely modular ensures the best fit and cleanliness
- Standard Eco mode
- 10-year warranty for a more trusted experience
cons
- The more expensive option for an average specification
- A louder fan choice, even with fan eco mode
Wattage: 850W | Rating: 80+ Gold | Design: Fully modular | Form Factor: ATX
The EVGA Supernova 850 GA is our second-place pick, and probably the most practical choice. If you think 1000W is too much for your installation, then 850W is the smarter choice. Of course, both EVGA and SeaSonic also make 750 units, but you won’t save much money if you go that route anyway.
This is an 850W PSU, with an 80+ Gold rating. It also happens to be completely modular and should fit most cases without any issues. This power supply should provide enough power for even some extremely high-end rigs.
Noise is not a problem with this power supply and it is also quite stable. The only slight downside is that the cables aren’t that great, but you can always go the sleeved cable route for a better look.
Corsair RM850x 2021

Corsair RM850x

Advantages
- Fully modular for customization and clean building
- Features a maglev fan for the quietest and longest performance
- Hybrid mode keeps the fan off until needed
- 10-year warranty to keep your PSU reliable and durable
cons
- Can be a more expensive option
Wattage: 850W | Rating: 80+ Gold | Design: Fully modular | Form Factor: ATX
This Corsair PSU isn’t that far behind the EVGA above. This is also an 850W ATX power supply with an 80+ Gold Rating. It also happens to be fully modular, just like the other two PSUs we’ve looked at so far.
Corsair’s RMx series is extremely reliable. This particular unit is a tier A power supply on LTT’s PSU tier list. It is also not too expensive as what you get is of high quality.
So the only problem here is that the cables are a bit stiff, and some of them might be a bit short. That’s not much of a problem, but the fact that they only include 2 PCIe cables is a bit disappointing.
You can get a third PCIe cable from Corsair, which you’ll probably need, as the more powerful GPUs these days require 3 PCIe connections from the power supply.
Last word
That’s about it for this guide on the best power supply for Intel 13th gen. Keep in mind that you can still opt for a 750W power supply and be happy with it. However, given the prices and value, it’s better to upgrade to an 850W to be on the safe side. After all, you want your new gaming rig to be stable for years to come. We hope you enjoyed our article on the best PSU for Intel 13th Gen CPUs.
