Whether you're building a gaming PC from scratch or upgrading your current setup, the heart of it is the motherboard. Without it, your choice of CPU, RAM, and graphics card is completely irrelevant. The motherboard is the glue that holds it all together, so it's important to get it right.
Whether you're building with Intel or AMD CPUs, there will be something for you. Prime Day is happening now, but in true Amazon fashion, early deals were already starting to pop up over the weekend. We'll be constantly updating with the best motherboard deals for you right here throughout the Prime Day event.

Today's best Prime Day AMD motherboard deals

One of the cheapest motherboards you'll likely find for a budget AMD builds if you don't mind sticking with DDR4 memory and PCIe 3.0 expansion cards. It's a full-size ATX board for less than $100, so it's hard to fault its last-gen feature set.

Prime Day 2023: Dates and important information
Amazon Prime Day has almost always happened in July, rescheduled to October 2020 due to the COVID-19 pandemic, and closer to summer in June 2021. The specific days vary, and 2023 sees Tuesday and Wednesday chosen for the 48-hour sales bonanza.
Discounts don't necessarily wait for the official start date on Amazon, so some deals are already live across the store, but Prime Day officially closes at midnight on the last day in your region. Not just anyone can take advantage of the savings, though, so make sure you're ready.
When did Amazon Prime Day happen?
This year, Prime Day ran between 00.01 on July 11 and 23.59 on July 12 for '48 hours of great savings across all categories on everything they need for summer and beyond,' detailed in an official Amazon press release.
Could anyone take advantage of Prime Day?
To have qualified for Prime Day savings, you needed an active Amazon Prime subscription. You could either pay $14.99 a month or $139 annually, although if you were signing up for the first time, you'd be eligible for a 30-day Amazon Prime free trial which could be used during Prime Day and cancelled afterward.
Choosing the right Prime Day motherboard deal
Enjoying the best deal is one thing, but picking the right deal for your PC is important when it comes to the motherboard. You should always spend your money wisely and get what you need within your budget. When putting together a new PC build or upgrading an existing desktop, a new motherboard allows you to use the latest processors from Intel and AMD.
You must decide on which processor you'd like to use. If you plan on using AMD's Ryzen 3000 or 5000 series, you'll need an AM4 socket motherboard, while Ryzen 7000 will require an AM5. Intel 12th and 13th Gen CPUs will both work on 600 and 700 series chipsets, while 11th Gen will need to step down to 500.
Likewise take a good look at the feature set. If you're not going to be overclocking, for example, you can save some money by B-series chipset motherboard from AMD and Intel's respective platforms.
