Best Budget Intel ATX Motherboards

1. MSI B360 Gaming Plus – LGA 1151 – Recommended Budget ATX Motherboard for Gaming

A highly affordable gaming motherboard for Intel based systems. Features beautiful red color accents.

First up we have one of the most popular budget ATX motherboard out there. This motherboard is excellent for those who are budget conscious but want to built an Intel based gaming rig.

The motherboard features a single PCIe X16 slot, PCIe X4 slot and 4 x PCIe X1 slots.

Note with a configuration like this, while this motherboard can support 2-way AMD crossfire setup, it cannot support an NVIDIA SLI setup should you wish to install two graphics cards.

It is worth noting that the huge array of X1 slots that it offers can be used for installing smaller components like a WiFi card or a dedicated sound card etc.

Catering specifically to the gamers, this motherboard comes with Fnatic team endorsement, RGB lights, color accents as well as comes VR-Ready from the get-go.

This motherboard is compatible with the processors that utilize the LGA 1151 socket. Hence it is suitable for 9th and 8th generation Intel processors. If you are looking for a motherboard that supports 10th gen Intel processors, then look at our next motherboard review.

All in all, if you came here looking for cheapest Intel based option, then this is the best budget ATX motherboard in our opinion.

2. GIGABYTE Z490 – Features LGA 1200 Socket

One of the latest motherboard built with the latest LGA 1200 socket for the 10th generation Intel processors.

This motherboard is more expensive as compared to the previous motherboard, however, it is one of few out there that features the latest LGA 1200 socket for supporting the Intel 10th generation processors.

But besides that, the value in terms of performance and configuration it offers is second to none. For starters this is a high quality board. If you cant tell that by the size of heat sinks installed than you should be able to tell by the number of VRMs this motherboard features.

If you are not aware, VRMs regulate the voltage across the motherboard. The higher the number of VRMs the better voltage control it’ll offer. The better the voltage control, the better would be its overclocking ability. Of course, the capacitors, chokes and mosfet used in the VRM also matter, but this features a phase power design 11+1.

In other words, it has 11 VRMs for the processors and 1 for the RAM. Normal motherboard cap out at 8 VRMs for the processor.

Another important consideration here is that this motherboard features 2 x M.2 slots. Which means you would be able to add dual SSDs on this.

Unfortunately though, this one still does not add support for NVIDIA SLI configuration yet it does offer support for AMD Crossfire setup.

It features a single PCIe X16 slot, one PCIe X4 slot and 3 x PCIe X1 slots which is more or less like the MSI B360 Gaming Plus above.

All in all, if you came here looking for a motherboard with support for LGA 1200 socket, then this is the best budget ATX motherboard in our opinion.

3. MSI MPG Z390 Gaming Edge AC – LGA 1151 – For SLI Setup

An essential motherboard for enthusiasts who seek to build a gaming rig with dual NVIDIA Graphics card.

This is not the most affordable motherboard out there, but if you are SPECIFICALLY looking to build a gaming PC with 2 x NVIDIA card on an ATX board, then you may find this to be the most affordable and value-rich.

Again, let us reiterate that this is not cheapest motherboard, but it caters to a specific set of gamers. The reason why we have chosen this motherboard is that because it offers an exceptional value for SLI gamers.

For starters, it offers 3 x PCIe X16 slots with the following mode of operation x16/x0/x4, x8/x8/x4. What this basically tells you is that it can either support NVIDIA 2 – way SLI with an X4 slot to spare, or support 3-way AMD Crossfire.

Besides the X16 size slots, this motherboard also features 3 x PCIe X1 slots for adding smaller add-in card. It also offers dual M.2 slots for adding two SSD drives.

Another attractive feature we found on this motherboard is that it comes with a built-in WiFi modem.

Besides that, this motherboard offers a ton of gaming-centric features from powerful and large heatsink to high quality capacitors and chokes for the VRMs. The gaming centric-features are also evident from its software as well as the looks.

All in all, this is the best budget ATX motherboard if you are adamant on building an ATX PC with an NVIDIA SLI configuration.

Best Budget AMD ATX Motherboards

1. ASRock B450 PRO4 – AM4 – Recommended AMD Option

One of the most affordable AM4 motherboard with an ATX form factor. Excellent for budget gaming or performance builds.

When it comes to ATX motherboards, this is certainly among the cheapest out there and also the cheapest in this list.

Therefore, if you came here looking for a quality option that would cost you the least, then this is the best budget gaming motherboard in our opinion.

This motherboard is compatible with the AMD processors that utilize the AM4 socket. This includes all the latest Ryzen processors from 1, 2 and 3rd generation.

As far as expandability goes, this motherboard features a decent array of PCIe slots. It has a single PCIe X16 slot, one PCIe X4 slot and four PCIe x1 slots.

Hence this motherboard is suitable for AMD Crossfire but not for an SLI setup.

Besides that, not only does it offers 6 x SATA 3 ports for connecting your hard disk and optical drives, it also offers 2 x M.2 Slots for connecting 2 SSDs – which is very rare for a budget motherboard.

It should be noted, however, that one of the M.2 slots supports a SATA SSD while the other supports the much faster NVME PCIe SSD.

All in all, this is is by far the best budget ATX motherboard as far as the price tag and overall value goes.

While it is minimal and offers no color accents, lights or large heatsinks for enhancing looks, it is simply a functional model.

2. ASUS ROG Strix B450-F – AM4 – Recommended AMD Option for Gamers

A very popular ATX motherboard that offers vast expandability. A recommended budget AMD gaming motherboard.

This is our personal favorite especially if you are planning on a building the ultimate AMD based system at the most economical cost as possible.

This motherboard does not support 2, but 3-Way AMD Crossfire. In other words, you can add three AMD graphics card to this for the ultimate gaming rig.

How? Well that is due to the fact that this motherboard offers one PCIe X16 slot along with 2 x PCIe X4 slots. As we know an AMD GPU requires a minimum of X4 to operate, hence 3-Way Crossfire is possible here.

Of course, if you are planning on building an economical PC, it will be difficult to procure 3 AMD GPUs, but the fact of the matter remains that this is an affordable ATX motherboard.

On top of that, it features high quality components like large heatsinks, ASUS proprietary 5-way optimization for overclockers, and also breathing RGB lights for the gaming ambiance.

Besides, ASUS ROG needs no introduction. This one of the oldest, most respected and established brand for gamers. Any gamer worth his/her salt would have heard of Asus ROG one way or another.

Therefore, this motherboard only caters to those who understand the need of having a high expandability.


Most of the gaming motherboards conform to the ATX form factor. It is for this reason that finding a simple ATX motherboard for home or office use is almost impossible.

You will largely see ATX motherboards being advertised and catered to the need of the gamers with gaming centric features and overclocking abilities.
