Do I need a new PSU for Intel Core Ultra 200 Series CPUs?

Before we answer the question above, let's quickly discuss Intel Core Ultra 200S Series CPUs. So, what's what's new about these Intel Core Ultra 200S Series Processors? This series of processors is also known as Arrow Lake, a series of high-performance processors designed to be more focused on performance, power efficiency, and AI integration. There are a few things worth highlighting first without getting too much into the weeds.

• These new chips utilize Intel's hybrid architectural design, which is similar to its predecessors. P-cores are intended to handle very demanding, complex tasks, and E-cores are assigned to process regular or repetitive tasks that do not require a lot of power. Another major change from the previous generation is the removal of the Hyper-Threading feature in favor of power efficiency.

• Intel Core Ultra 200S Series processors will support DDR5 memory. In fact, they will only support DDR5 for faster data rates and improved overall system bandwidth. They will not support DDR4. So, if you are currently on a DDR5 platform, you can continue using the same kit. On top of that, Core Ultra 200S CPUs will also support DDR5 CUDIMM (Clocked Unbuffered Dual Inline)—a new type of DIMM that will allow users to reach even higher frequencies.

• If you are planning to build a PC using these new CPUs, you will need a new motherboard with the new 800-series chipset. The latest Intel Core Ultra 200S CPUs will utilize a new socket called LGA-1851, which has more pins than the previous LGA-1700. However, these two Intel sockets have the same mounting hole measurements, so you can keep the same cooling system if you already have an Intel motherboard with socket LGA-1700.

Now, onto the main question: Do I need a new PSU for an Intel Core Ultra 200S build?

The Intel Core Ultra 200S CPUs are designed to be power-efficient, so you probably won't need a new power supply unless you're upgrading key components like the GPU, which you will always need to account for when choosing the right PSU wattage for your PC. These new Intel CPUs can deliver the same performance as their predecessor while consuming significantly less power, which would essentially lead to lower CPU temps while your system is under load. This thermal drop is great news for power users, gamers, and everyone in between who has experienced the high temperatures and power consumption of previous CPU generations.

That said, if you really want to make sure that you have adequate wattage to power your PC system, it would be best to use CORSAIR's PSU calculator to ensure that you are getting the appropriate PSU for your build so you don't second-guess yourself. For starters, here are a few CORSAIR PSUs designed to fit in any PC build.

The new RMx Series PSU is the 3rd generation of CORSAIR's RMx PSU line. These fully modular units are designed to meet and exceed the demands of modern computing with top-tier efficiency and great value. With the integration of ATX 3.1 and PCIe 5.1 standards, including a native 12V-2x6 connector, these PSUs are ready to drive the next generation of high-performance computing.

The RMx SHIFT takes all the modular cable connections a standard power supply provides and "shifts" them to the side of the PSU, allowing for simpler cable management and easier cable access. The CORSAIR RMx SHIFT is Intel ATX 3.0 certified, PCIe 5.0 compliant, and holds two efficiency certifications.

The HX Series PSU is a digital PC power supply that is a modern iteration of the traditional PSU, with a ton of advanced features and new technology. Unlike their analog counterparts, digital power supplies have an embedded digital microprocessor to handle power distribution and management. This finer control allows for more accurate, efficient, and performance-driven outcomes in your computing environment.
