No money, no honey

If you are reading this, I’m going to take a wild guess that you’re broke or don’t have a lot of cash to part with. That’s fine; I understand people in that position because I used to be there myself growing up. That's why I have written this guide. The truth is that building a gaming pc for under $300 really isn’t going to give you a super amazing great build (something other guides won’t tell you) and in fact if you ask some people if it’s possible to build a gaming pc for 300 dollars then they might even just start laughing uncontrollably in your face. Those people can suck it; this build will let you play games like PubG, Fortnite, Dota and League. Just make sure to turn your in-game settings down to about 720p or 60 FPS, and you’ll be good to go.

Best Gaming PC Under $300

This build features an AMD processor, MSI motherboard and sexy glass panel AeroCool case to wrap around your budget hardware. Also keep in mind that since you’re building your own build, you can easily take out parts in the future and sell them on eBay for example. When you’ve got a bit more spending money, then you can buy more powerful components to replace them which is a beautiful thing. If you are an individual who is extremely fat, lazy or technologically inept, then I would suggest scrolling to the bottom of this page and checking out the refurbished pre-built PC. If you are none of these things then keep on reading, we are about to go on an epic journey together and I'm going to be more serious about things.

$300 - $337 Estimate

Our choice of a motherboard is entry level but will still give you excellent performance and at the most economical price possible considering our budget for gaming. The manufacturing company MSI does not only sell motherboard's but offers after sale services and technical support in case anyone has issues with their tech. The design of the Gigabyte B450M motherboard allows for upgrades (M.2 Slot) and can support other processors if you wanted to install them in future upgrades. A good place to start your cheaper builds.

Considering the 300$ budget, this is the most ideal and best value money component to power our graphics. It really is an excellent graphics card. On a positive note, for it's performance the 3200G is one of the best (if not the best) processor in its price-point in comparison to others in the market. Keep in mind though, that to get optimum functionality on these budget graphic cards, you might need to lower the settings to maximize the performance. Though you might be able to play lower in depth games at average Frame rates(40-50Fps). To cut down on costs, you might also consider acquiring a second-hand since it will give you the same level of performance. Just head over to Amazon if you want to do that.

The EVGA’s 450W power supply packs some serious power under the hood. For a device with such excellent craftsmanship and our budget we can only incorporate the use of basic modularity features. Due to the basic modularity features, it isn't recommended for anyone planing to run a dedicated Graphics Card.But, all in all, the EVGA 450 BR will do the job. It also is easy to install for new builders. Be sure to check it out.

Compared to other companies, the EVGA 450 is a cheaper alternative. The low price is however not an indicator of inferior quality. Over the years the company has built a reputation for manufacturing powerful and durable GPU and PSUs. The component also comes with a Bronze (85%)certified power supply unit.

4) Patriot Viper Steel Series DDR4 8GB (2 x 4GB) 3200MHz

I intentionally settled for a basic DDR4 RAM and a motherboard that had enough room to allow for future upgrades. The basic 8 GB RAM that comes with the device is sufficient enough for basic multitasking tasks but will fall short on a 4k gaming performance. Here is a tip though, to improve the overall performance, you could add to the RAM by purchasing extra RAM sticks. Even with the slight dip in performance when using a single RAM stick, the Patriot Viper DDR4 RAM is quite reliable and comes at a very cheap price which as you have guessed by now is a huge factor with this build.

When coming up with the CPU the cost of storage was way cheaper compared to the last time I planned an upgrade. With the pricing in mind, a smaller 240 GB hard drive was the ideal storage capacity to settle for. Such storage capacity is sufficient and gives you enough space to store games and other media you may have. It may fall short of the newer ones on quality but based on the budget it will be sufficient to start with.

This case is not the most flashy or expensive but there is a lot to like. It has a very efficient cooling mechanism that relies on airflow (though its front mechanism) and a silent pre installed 120mm fan that  helps controls the intake and the exhaust of the cooling system. The case is quite unique in the sense that it is very compact and firm with a full  Acrylic Sine Panel aluminium front. With this case you also get 7 PCI Expansion slots with bottom and top magnetic filters. If you are still here reading this, thank you. If you get stuck building your PC with the components in this guide, you can let me know in the comments.

BONUS: Pre Built HP Option

If you aren't interested in building your own Gaming PC, due to the complexities or length of time it takes, that is entirely understandable, and you should know that you are not alone. Sometimes for a lot of people a one-time payment and receiving a plug and play PC is the best option. I have decided to include the Allied Gaming Desktop PC here in this guide due to the massive amount of quality you get for the price. It is AMD RadeonVega, has 8gb of DDR4 Ram, warranty and even comes with a mouse and keyboard. The one thing I will be upfront about is that it is a refurbished PC.

Don't let that put you off however because the fact is that for this budget it is going to hard, if not impossible to find a pre-built gaming PC with better specs for the price. Be quick though, the stock is limited, and with Christmas around the corner, this PC will be gone in no time.
