This is the latest build guide on the best gaming pc under $2500 in 2021 – [Latest Build Guide] where I have written about my new setup on my gaming pc.

Since the release of the Intel i5-8400K, Intel’s Coffee Lake CPU lines have been competitive to the Ryzen 5 CPUs. Though the Coffee Lake series has not been able to beat out the Ryzen 7 series so far, it is still a very strong CPU line. With the release of the Coffee Lake-H series, we now have the highest performing CPU with up to 12 cores and 24 threads with a base clock of 2.8GHz and a maximum turbo clock of 4.6GHz. The 12-core i5-9600K and the 10-core i7-9700K are now the fastest CPUs under the $500 mark.

Dual-channel memory is always preferable than single-channel memory! Even the cheapest systems these days come with dual-channel RAM, so having a single one in a $2500 PC is pointless. This G-Skill Ripjaws 32GB (2 x 16GB) DDR4 RAM is fully compatible with Intel CPUs, therefore I recommend it. 

Also, this RAM is one of my personally tried and proven gaming components, and believe me when I tell it brings gaming to a whole new level of smoothness. It’s also very steady throughout the rendering process.

Meshify C Fractal Design (PC Case)

My suggestions for a PC Case usually include something that is spacious and has a decent ventilation arrangement, since gaming PCs may become pretty hot. And, hands down, Fractal Design Meshify C is the best choice I’ve ever seen. Because it’s constructed of mesh, it has one of the greatest airflow settings. Don’t worry; the mesh doesn’t feel or seem cheap when placed on a computer desk; rather, it looks expensive and eye-catching. 

Due to the large area, this PC Case can accommodate all of your necessary and extraneous gear, including water cooling or custom tubing! It can even accommodate radiators with a diameter of 240mm. 


The first issue that prompted us move from pre-builts to bespoke gaming PCs was a poor power supply. As a result, we won’t be slacking on this one! You can’t go wrong with the EVGA Supernova 750 G3 as a power supply. It works well with the processor we suggest (Intel Core i9 10850k). 

The quality of the cables, complete modularity, and, of course, EVGA’s certified guarantee will all impress you. So, with this top-of-the-line PSU for Intel i9 Processors, you can finally say goodbye to subpar power supply.


Buying Guide for a Custom Gaming PC


When it comes to CPU, you should always strive for the best of the best within your budget (don’t skimp on CPU!). Depending on your preferences and use, Intel Core i7-i9 or AMD Ryzen will be the best option for gaming. If you want my advice, buy the latest Intel Core i7 for the greatest gaming performance, or the AMD Ryzen 9 3900X if you’re an AMD fan. You will not be disappointed with your purchases. 

Computer Graphics Card

It won’t be a flawless gaming PC no matter how good your gaming CPU is if you don’t have a graphics card that’s comparable. If you’re on a tight budget, the Nvidia RTX 2080Ti is the finest consumer GPU on the market. Though I’m considering the new Nvidia RTX 3090, it’s a little on the pricey side. Anyway, the RTX 2080Ti has the greatest performance to price ratio, and I am certain that no other graphics card can match it. If you’re a novice searching for a less costly option, the Nvidia GTX 1660 Ti is the way to go.

Cooler for the CPU

No matter what your gaming PC’s hardware specs are, you’ll almost certainly need a CPU Cooler to prevent it from overheating. Gaming PCs become heated quickly, and if these problems aren’t addressed, you’ll be in serious danger. As a result, choose a CPU Cooler that does a good job while not taking up a lot of room in your PC case. Noctua is my go-to brand for CPU coolers; check out their offerings and make your decision based on your needs! 

Storage and Memory

When constructing a $2500 PC, you won’t want to skimp on memory and storage after investing in such a powerful CPU and GPU. 2 x 16GB of fast 3200MHz memory is required for memory. This memory will suffice for all of your gaming, multitasking, and surfing requirements, as well as a rendering and production workstation. Also, dual-channel memory is always preferable than single-channel memory!

Consider a dual memory configuration as well! Get a separate boot drive with high consistency and sustained performance; as we stated in our setup, the Samsung 970 Evo Plus is a great choice, but comparable versions are also available. 

The sky is the limit in terms of capacity! I would recommend a 500GB SSD, but you may choose between 1TB and 2TB if you want to create a larger gaming library. Whatever you pick, remember the golden rule: SSD over HDD!

PC Case

Choose a PC case with the greatest ventilation since a gaming PC will undoubtedly need it. Not to mention, the PC Case has to be big enough to include all of your main components, including water cooling and huge radiators. When looking for a PC case, opt for one with a mesh design. 

The Best Prebuilt Gaming PC Under $2500

Not everyone is interested in building or customizing their own computer. There may be a variety of reasons for this, including a desire to avoid the complexities of connecting hardware, a desire to get a PC fast, or just a personal choice. Whatever your motivation, you can always get a prebuilt gaming PC from one of the many choices available.

Two of the most popular pre-built gaming PCs under $2500 are:

R11 Alienware


  • Intel Core i7-10700F processor
  • Nvidia RTX 2060 graphics card is included.
  • 32 GB of RAM, 1 TB SSD, and 2 TB HDD

Alienware is a well-known brand in the gaming PC industry, owing to its distinct looks. Aesthetics, on the other hand, are not for everyone. However, with its obviously exceptional features, the Alienware R11 takes the lead. 

The Alienware R11’s sleek and small design contains an Intel Core i7-10700F processor coupled with an Nvidia GeForce RTX 2060 graphics card, the ideal combination for seamless gaming. This gaming PC is available in a variety of configurations, so there are few choices and preferences. It’s a little expensive, but it’s still within the $2500 budget. 

Not to mention, the Alienware R11 comes with 32GB of RAM, a 1TB SSD, and a 2TB HDD. These specs will allow you to build a large gaming library without sacrificing lag-free gameplay. 

R10 Alienware


  • Intel AMD Ryzen 7 3700X processor
  • AMD Radeon RX 5700 XT graphics card is included.
  • 16GB RAM, 512TB SSD, and 1TB hard drive

The Alienware R11 was undoubtedly the first choice; all praise goes to Intel’s latest CPU range. However, Alienware takes the second spot on our list of recommendations since no one does gaming PCs better than Alienware. It’s for those who prefer AMD CPUs over Intel processors. 

The AMD Ryzen 7 3700X is housed in the Alienware R10’s sleek black casing. This chip isn’t only excellent for day-to-day productivity activities; it’s also fantastic for gaming (obviously!). That is precisely the purpose). However, it is quite similar to the Intel Core i7 processor.

Furthermore, the Graphics Card is also from AMD, making this PC a real gaming machine. Not to mention the 16GB RAM, which is more than adequate for multitasking and handling the bulk of tasks. Though I would have liked it more if there had been any space for upgrading, the chassis’ design prevents that. In any case, the Alienware R10 is a fantastic first computer!

FAQs – Frequently Asked Questions

How much does a high-end PC cost to build?

When it comes to constructing a computer, there is no precise number. A PC may be built for as little as $800. However, if you want to play high-end games (AAA titles), you’ll need the appropriate specifications. A high-end PC can set you back anywhere between $1500 and $2500, depending on the components you choose.

Is it cheaper to construct a PC or purchase one that has already been assembled?

Building a bespoke PC is considerably less expensive and more gratifying than buying a prebuilt PC. You may also add hardware and other characteristics based on your preferences and use. On the other hand, although a prebuilt PC is more costly, it is a simpler and faster alternative.

Why are prebuilt computers a poor idea?

Prebuilt PCs have a weak power supply and a low construction quality. Even if you can get the newest and most powerful CPUs and GPUs in prebuilt PCs, the lack of a single cooling fan, a bad power supply (PSU), and an ordinary motherboard will make your experience boring.
