 Best PSU For i7-13700K (750W, 850W, 1000W)

Sorting out all your power issues with the rest of the system, the best PSU for i7-13700K has come to the rescue. For such a powerful CPU, you have to choose a capable and viable option to fuel the rest of your components with it. This is why we have this list of products that will serve you all you need without cutting you short on money as well. Starting from the wattage, this category comes with 650W as in Cooler Master as well as 1000W in Seasonic Prime PX-1000.

From the requirements mentioned before, you now have some vague idea on how much wattage your system requires. So further, we have the certification that is also in bronze, Gold and Platinum as the last 2 will give you more efficiency up to 94% under 50 to 20% of load. The fans that are installed in these PSUs are a great way to control any heat issues that might come up during overclocking hours. They are various in designs and shape some have 0dB technology and contain dual ball bearings like ROG strix while others have fanless modes.

When the cables are an issue for the extra heat to move out because they might be blocking the path, a fully modular cabling system is introduced. You can remove any cluttering or tangled wires while also clearing paths at the back of your tidy system. With such freedom over the cabling, semi modular is a little resisting because all wires cannot be plugged out as you need. This is for those users who do not care about the cables or might be too lazy to do so.

Furthermore, 5 to 12 years of warranty should be present when you are buying a power supply because this will give you coverage for any loss. Speaking of loss, electrical protections are a crucial part of a power supply as yours should be covering it too. They might be over power, over current, short circuit, under power etc. Now you are ready for a battle headed your way and a pile of work for your productive work ethic.

Our Recommended list of the Best PSU For i7-13700K

  1. ASUS ROG STRIX 1000W Gold PSU
  2. EVGA 220-G5-0850-X1 SuperNova 850 G5 Power Supply
  3. Corsair RMX Series, RM750x, 750 Watt
  4. Cooler Master Watt 650 Watt Semi Fanless Modular Power Supply

  6. Seasonic PRIME PX-1000, 1000W 80+ Platinum, Full Modular

Intel Core i7-13700K PSU Requirements:

  • Based only on the CPU, you need minimum 500 wattage of PSU, recommended: up to 1000W
  • If you have attached the higher end GPU and latest motherboard, you have to keep in mind the fuel for other components as well.
  • There is a 125W power draw from the CPU alone and it can easily reach 245W in boost mode. This is why your minimum wattage should be compatible with your system’s requirements.
  • Recommended certification: Gold
  • Semi modular and non modular cabling are preferred

13700K vs 12700K:

  1. Both these processors support the same socket, but if you are thinking of using a Z790 chipset motherboard, there will be a difference.
  2. The latest CPU has more cores and threads and when this feature is bigger in number, the better it performs.
  3. Compared to 12700K PSU, the latest processor is great at winning over the boost speed on both P and E cores. It means you can game well with this processor as well as excel in multi core or single core performance.
  4. Similarly the cache is bigger in 13700K and because it is the successor of 12700K, there has to be some major changes in these features.
  5. For the maximum amount of energy that your CPU will use, 12700K consumes lower TDP at most load it can get. Even on the boost TDP, this CPU beats 13700K as it has less heat to deal with.
  6. If you are on a budget cut, 12700K will be an appropriate option because 13700K is budget friendly compared to 13900K but it still has major differences from 12700K.

Your cabling should be fully modular so that you can manage the wires as you want by attaching only the necessary ones. By doing so, you can reduce cable clutter and keep the look of your system very tidy as the airflow will also be cleared by its path. Not to forget about the 10 year warranty that has been offered to the user for worry free working.this PSU is also supported by AMD RX 6500 XT and RTX 4090 PSU.


Another competition for Asus is the SeaSonic Electronics prime that comes with the same 1000W power supply. But this does not has full 1000W combined for +12V but it provides a little more protection as compared to ASUS ROG strix.

Generally an i7 processor works great with 750 up to 1000W of power from a PSU.

How Do I Know What PSU I Need?

The best choice is to calculate the total volts your hardware components are using and multiply the total amps with it.

What Happens If A PSU Is Too Weak?

If you do not select the right choice for your system, it might prove to be too weak or underpowered for your needs. The symptoms that are able to get you to this conclusion are randomly crashing programs or applications, shut down systems out of the blue, system freezing, blue screen etc.
