8 Mins read


Last Updated on November 1, 2021 by ViCadia

Although a budget of $700 isn’t enough to build a killer gaming PC, it is still enough to build a decent mid-range computer that will be able to quickly load office applications, and offer an enjoyable gaming experience at 1080p resolution in most video games. With this kind of machine you can also build a great home media center that will allow you to easily stream TV shows and movies to your big screen TV.

Since our $700 PC build is primarily designed for users that are on a tight budget, most of the components used in this PC build are already a few years old. Not having the latest PC components, however, isn’t necessarily bad. In fact, it has never been a better time to buy the last-gen flagship PC components, as they are now quite affordable, and can still be found in most retail stores. Intel Core i5-9400F CPU is one such component which we decided to install in our $700 PC build. With eight 6 cores and 6 threads, the Core i5-9400F is still an amazing CPU that offers great price-to-performance ratio, and can be acquired for less than $200. Alongside this CPU, our $700 PC build also features 16 GB of DDR4 RAM, and a GeForce GTX 1050 Ti graphics card with 4 GB of VRAM. Overall, this PC build should offer satisfactory gaming performance at 1080p resolution, and will be suitable to most casual PC players, as well as some advanced PC users that need a good machine for office work and programming. This build, however, wasn’t built with overclocking in mind, so if that is something that interests you, then take a look at our best overclocking PC build here.

With the latter on our mind, let’s not waste any words further and take a look at our PC build.

The total cost of components we’ve listed above should amount to around $700. Since prices change every day, this figure may exceed our designated budget of $700 at the time you are reading this, so don’t be too surprised if you find the total cost of our PC build exceeding our planned budget.

Expected Gaming Performance

1080p Gaming @ Very High Settingsi5-9400F + GTX 1050 Ti
Apex Legends73 FPS
Grand Theft Auto V77 FPS
Forza Horizon 459 FPS
Resident Evil 355 FPS
Fortnite80 FPS
Counter-Strike: Global Offensive210 FPS
Shadow of the Tomb Raider38 FPS

Obviously, our $700 budget gaming PC isn’t designed to smoothly run the latest PC titles such as Cyberpunk 2077, or Assassin’s Creed Valhalla, but is more than enough powerful to run Fortnite or Apex Legends on very high settings at more than 60 FPS on average. Even some more graphically intensive titles, such as Forza Horizon 4 and Resident Evil 3 can be smoothly run on our $700 PC build, which is quite impressive given the fact that the GeForce GTX 1050 Ti is now a five years old GPU. In short, if you are looking for a simple PC build to play older PC games, or eSports games, than this build will be more than enough for you. Of course, you can always upgrade the GPU if you don’t prefer this one, as Core i5-9400F still offers very good computing performance, and it won’t bottleneck even some high-end cards such as the NVIDIA GeForce RTX 2060. If you are interested in specific details of each individual component of our $700 PC build, then keep reading further.


Processor: Intel Core i5-9400F

Cores/Threads: 6C/6T | Base Clock: 2.9 GHz | Boost Clock: 4.1 GHz | TDP: 65 W | PassMark Score: 9.549

Although Intel Core i5-9400F is now more than 2 years old, it is still a very decent mid-range desktop processor that is able to provide strong computing performance. Despite the lack of hyperthreading features, this hexa-core, 6-thread processor features very strong single-threaded performance, and as such is able to deliver optimal gaming experience, as well as to provide enough power to smoothly run some professional applications. With a TDP of 65 watts, the i5-9400F is quite energy-efficient CPU, and you won’t need to buy an aftermarket cooler to properly cool it. Obviously, the only major drawback of this CPU is the fact that it doesn’t support overclocking, which some users may find disappointing.

Motherboard: ASRock B365M Pro4

Form Factor: Micro ATX | Socket: LGA1151 | Chipset: Intel B365 | Memory Support: 4 x DDR4-2666 | Features: 2 x PCIe 3.0 x16, 1 x PCIe 3.0 x1, 6 x SATA3, 2 x M.2

Despite the fact that ASRock B365M Pro4 is sold as a budget micro ATX motherboard for 9th and 8th Gen Intel Core CPUs, this compact motherboard comes with an abundance of useful features which are able to put to shame even some high-end motherboards. The B365M Pro4 comes with two full-sized PCIe 3.0 x16 slots which allow you to create custom AMD Quad CrossFireX multi-GPU configurations, and you also get two M.2 slots for NVMe SSDs, which is quite impressive for a sub-$100 motherboard. The B365M Pro4 also comes with six SATA3 ports, and 7 USB 3.1 Gen 1 ports (including one USB Type-C port), which give you plenty of options to quickly and efficiently transfer all of your data. Overall, the ASRock B365M Pro4 offers almost everything an ordinary mainstream user would want to have in his or hers PC, so there is no reason purchasing a more expensive motherboard if you don’t wish to overclock your system.

Memory: Corsair Vengeance LPX 16GB (2x8GB) DDR4 2666 MHz Kit

Speed: DDR4 2666 MHz | Timings: 16-18-18-35 | CAS Latency: 16 | Operating Voltage: 1.20V | Capacity: 2 x 8GB

Corsair’s Vengeance LPX DDR4 memory modules are great DDR4 RAM memory modules designed for high-performance overclocking that come with a very affordable price. This 16 GB kit consists of two 8-gigabyte sticks, each running at a frequency of 2,666 MHz. With a CAS 16 latency, and very good timings at stock speed, this is one of the best budget high-performance memory kits currently available on the market. Featuring heatspreader made of pure aluminum, these sticks run very cool, and due to their 8-layer PCB design offer incredible stability while being overclocked. Thanks to the XMP 2.0 support, these sticks are easy to overclock, so you don’t have to worry about manually tuning their timings and frequency in order to achieve system stability.

Graphics Card: ASUS GeForce GTX 1050 Ti 4GB Phoenix Fan Edition

Boost Clock: 1392 MHz | Memory: 4GB GDDR5 | Length: 192 mm | Power Connectors: None | Outputs: 1 x DP, 1 x HDMI, 1 x DVI

In times when a decent graphics card costs more than a bar of gold, it is nice to stumble upon GPUs like the ASUS GeForce GTX 1050 Ti Phoenix Fan Edition which doesn’t cost too much, and is still able to deliver solid gaming experience. Obviously, this graphics card isn’t powerful enough to run latest AAA titles even on medium settings at 1080p resolution, but is quite capable of smoothly running most eSports games, as well as older PC titles at 60 FPS. Whether it’s DOTA 2, LOL, Apex Legends, Fortnite, or Grand Theft Auto V, this GPU is able to run all these games smoothly, which is nice if you like playing these games. One major advantage of this particular variant of GTX 1050 Ti is the fact that it requires no power connectors, since it’s extremely energy efficient. The ASUS GTX 1050 Ti Phoenix Edition also comes with a single fan, which sometimes can get a bit too loud, but overall does a pretty good job keeping this card cool.

Solid State Drive: Kingston A400 480GB M.2 SSD

Capacity: 480GB | Interface: M.2 PCIe 3.0 x4 | Max. Read Speed: Up to 500 MB/s | Max. Write Speed: Up to 450 MB/s

These days if you want to have a fast and snappy PC, buying an NVMe SSD is a must. This is why our PC build comes with Kingston’s A400 480 GB M.2 NVMe SSD which offers great performance for an affordable price. Besides occupying much less space in your PC case than the old 3.5-inch hard drives, the NVMe drives also offer unprecedented data transfer speeds that can’t be achieved using the SATA3 interface. Not only that these drives enable you to load games blazingly fast, but they also allow your operating system to boot in mere seconds. The above-mentioned Kingston A400 SSD offers enough storage space to accommodate the Windows 10 OS and multiple PC games and applications. In case you need more space, you can always go with a larger SSD, or, you can buy a few classic 3.5-inch hard drives which offer significantly lower price per gigabyte of storage.

Power Supply: Thermaltake Smart 500W 80+ White Certified

Form Factor: ATX | Capacity: 500W | Efficiency rating: 80 PLUS White Certified | Modularity: Non-modular

Since our PC build doesn’t consuming more than 350 watts of power under full load, there is no reason to install a powerful high-performance power supply unit to feed it with power. The Thermaltake Smart 500W 80+ PSU is more than enough capable to get the job done. Featuring a 120 mm fan, as well as multiple voltage and current spike protections, this is a very efficient and reliable PSU that will keep your PC running for years. Besides being very quiet, it is also very easy to install, and it features a variety of connectors that are able to deliver power to all sorts of PC components.

Case: Zalman S3

Form Factor: Mid Tower | Motherboard Support: ATX, Micro-ATX, Mini-ITX | Dimensions: 412 × 189 × 451 mm | Radiator Support: 1 x 120 mm, 1 x 120 mm | I/O Ports: USB 2.0 x 2, USB 3.0 x 1, HD Audio x 1, Mic x 1 | Drive Bays: 2 x 3.5″, 2 x 2.5″

Zalman S3 is a compact and budget mid tower ATX computer case that perfectly balances low price with nice aesthetics, and wide variety of features. For a price of around $50, the Zalman S3 is able to offer a full acrylic side panel, top I/O panel with three USB ports, top magnetic dust filter and bottom PSU dust filter, as well as support for 330 mm long graphics cards. The Zalman S3 can also house up to two 3.5″ hard drives, and two 2.5″ drives, or up to four 2.5″ storage drives. Despite being a rather compact computer case, the S3 supports installation of up to eight 120 mm fans. Unfortunately, this case wasn’t designed to accommodate large liquid cooling radiators, but if you want to cool your CPU with a 120 mm AIO liquid cooler, then this case will offer enough space for its installation.


And that’s it! With our $700 PC build you’ll be able to play latest eSports titles without any hiccups, and will also have enough compute power to smoothly use professional applications such as Adobe Photoshop or Blender.
