Socket AM4 AMD B450 ATX Motherboard

The ASUS TUF B450-PLUS GAMING is an ATX motherboard built around the AMD B450 chipset. It uses the Socket AM4 interface and supports DDR4 memory up to 64 GB. The board is sold as a new component with a 100 % inspection performed before dispatch.

Builders needing a standard AM4 platform

This board suits builders assembling a system on the AM4 socket with DDR4 memory who do not require integrated Wi-Fi. It is not suitable for anyone needing a different CPU socket, a newer chipset, or memory types other than DDR4.

Maximum memory capacity of 64 GB DDR4

The single specification that decides fit is the 64 GB DDR4 limit. If your planned build requires more memory than this, or a different memory generation, this motherboard will not meet the requirement.

Questions about this item

How often will the included CMOS battery need replacing?

The supplied CMOS battery maintains BIOS settings and typically lasts several years before replacement is needed.

What memory capacity ceiling will I hit first with four DDR4 slots?

The board supports up to 64GB total across its DDR4 slots, so that is the hard limit regardless of module size.

How much heat and fan noise should I expect from the B450 chipset during all-day loads?

The B450 chipset runs cool enough for passive cooling, so added heat and noise inside the case are minimal.
