Build the best gaming pc under $400 for 2019 (Ryzen Build)

$400 Master Gaming PC

For 400 dollars, you can build a decent PC if you choose the best possible components available right now. The PC configuration I have listed is for gaming at 1080p and will give you easily around 40 fps on average on medium settings in most of the games easily. I chose all the parts in this build with care and this should be the best available $400 Gaming PC for eSports games like CSGO, Overwatch and Rocket League. Other graphical intensive games like Rise of the Tomb Raider, Battlefield 1 and Doom should have no problems in running on medium settings too but this build is best for eSports games where you can actually get more than 50 fps in most cases.

In order to make this PC as much as future proof as possible, I have selected only the latest generation parts which have more performance and better power efficiency which will not only save you a lot of money in the future while upgrading but will also lessen your electricity bill. I named this PC “THE MASTER” Build.

What is better than the Ryzen 5 2400G APU?

AMD Ryzen 2400GSurely, AMD Ryzen 5 2400G is the best APU available today for just above $150. This is a combination of GPU and a CPU, that’s why it’s called an APU which means you will get the performance of a processor and a graphics card from this chip. You don’t need to buy a dedicated graphics card for this build and if you want to upgrade you can easily get one in the future but right now this chip is enough for playing all the games on medium-high settings and gives tough competition to the entry-level graphics cards from Nvidia and AMD which are GT 1030 and RX 550. But when you start to overclock this processor, you will unlock its true power.

As it is fully unlocked, you can take it to the next level by overclocking both the CPU and GPU from Ryzen Master software so that you can get a lot of boost in performance. All of this is easy and will help you gain at least 20-30% more performance if you do it properly. As for the specs of this APU, it is a Quad-core chip with 3.6Ghz as the base clock and 3.9Ghz as boost clock. It’s not only powerful but also power efficient having max TDP of 65 Watts. This chip comes with a stock AMD Wraith Stealth CPU cooler which should be enough for basic cooling. As I have used this APU in my friends build, I can without any doubt say that it is the best CPU for any budget build right now.

Memory, Motherboard, PSU and Case details

The motherboard I chose is from MSI which is ASRock B450M PRO4. As the Ryzen 2400G is overclockable, it’s best to use it on an unlocked chipset motherboard which should allow proper overclocking. There are a lot of B450 chipset motherboards available but the problem with most of them is either high price or bad VRM cooling. I previously used a B350 chipset board but due to some complications, I don’t recommend them now. Go with this one which has 6+3 power phases with decent heatsinks on both the VRM sections that will help you do some decent overclocking without overheating. This board is strong and should be good to connect any further devices.

It has all the basic slots and ports for memory, graphics cards and storage so you don’t need to worry about future upgrades. You can easily upgrade to a dedicated GPU in future if you ever want to. As for the RAM, I chose a single stick of 8GB DDR4 module from Ballistix Sport clocked at 2666Mhz. As there are only two DIMM slots on the motherboard, it’s best to use a single stick so that you can upgrade to 16Gb in the near future. The motherboard I chose supports very highly overclocked memories, therefore 2666Mhz RAM will help in a little boost in performance. Also, it is enough for 1080p gaming and there is no game that will utilize more than that on this resolution.

Thermaltake Smart 430WWith this configuration, you can open some applications at the back while gaming or do some basic multitasking because 8GB RAM accompanied by the quad-core Ryzen 2400G processor is fast enough for handling intensive tasks. As for storing your games, the build is capable of storing a lot of moderately sized games along with other data. 320GB of the hard drive is not the best solution for a long time but because I don’t want to increase the budget over $400, I chose the 1TB hard drive from Western Digital. Previously I used a 320GB one but now the total cost of the PC is reduced after some of the components got cheaper. So, it’s very beneficial to get a 1TB of hard drive that can store a lot of files including gaming, applications, miscellaneous files etc.

All of these parts will be powered by the Thermaltake Smart 430 Watts power supply which is rated at 80+ power efficiency. This power supply has all the required cables for powering all the components I have chosen and there will be many additional cables left which you can use for further upgrades. This one is a reliable power supply and you must not go below it because your components life depends on it.

Cooler Master MasterBox Lite 3.1 TGTo host all these parts, I have chosen the beautiful Cooler Master MasterBox Lite 3.1 case which has a large side window panel which will let you see all the components installed in it. It has a decent design with a stylish front panel which takes cool air from the top and bottom along with displaying the lighting effects if you install LED fans at the front.

It comes with a pre-installed 120mm fan at the rear for exhaust and you can add two 120mm fans at the front for better intake. It has decent cable management at the back and fairly sized routeing holes through which you can make it look cleaner. At a price of less than $40, this one stands out in the crowd and will beautify your RIG.
