Asus Pro B760M-CT CSM Motherboard Review: CSM Means Business

It’s been quite a while since we’ve looked at business-class motherboards, but since we’ve been on a streak of inexpensive Micro ATX boards, we want to make sure Asus is involved around that $100-150 range. On our test bench is the Asus Pro B650M-CT ($119.99). This tiny board is intended for SMBs and enterprises across retail, education, healthcare, manufacturing, and hospitality, but it is also a competent gamer!

Although anyone can use these boards, the CSM program they belong to is designed for businesses and multiple units. You get premium after-sales service/support, and any Pro, Prime CDM, and workstation series get the Asus Control Center Express software for real-time monitoring and management of multiple devices for IT. So while it works for everyone, businesses will get the most out of it.

Hardware-wise, there’s not a lot going on, but we must not forget that it’s intended for business, and most users do not have more than a couple of USB-connected devices on the rear IO. They can get away with the additional front-panel connectivity, however. Still, you get support for 12th-14th generation processors (including flagship-class SKUs), dual M.2 sockets and four SATA ports, 1 GbE networking (Wi-Fi is supported via Key-E socket, but not included), and a few Q-design features like Q-DIMM, Q-LED Core, and Q-Slot. You also get other features that are good for business, including Asus Boot Defender, a self-recovering BIOS, event logging, an anti-moisture coating, and more (see the product page for details).

Performance on our business board mixed in with the other B760M boards we tested recently. Like them, this board didn’t do well in longer-running, heavily threaded benchmarks/applications with our processor but did keep up with boards with higher limits in lightly threaded, shorter tests. In other words, it works well as an office machine working in things like MS Office and other light applications. Still, it will be slower than other boards with increased power limits/duration, especially when using high-powered CPUs like our Intel Core i9-14900K. Processors with lower TDPs can likely reach their potential, but the i9-14900K and i7-14700K (any other 200W+ processor) will have limited boost clocks in specific situations.

Below, we’ll dig into the details and see how it performed across all of the tests against other motherboards, including other Micro ATX B760 (and Z790) options. This board won’t make the best motherboard list, but it still might be a good option to build with, especially if it’s used in an office environment where its features are worth more to the buyer. Before we get into details, we’ll start by listing the specifications from the Asus website.

Specifications: Asus B760M-CT

Inside the Box of the Asus B760M-CT

Inside the box are a couple of accessories designed to get you started: two SATA cables, the I/O shield, screw packages for M.2, ACC Express activation key card, and a user guide. Not much, but it’s everything you need outside of drivers (download from the Asus website) to get going.

Design of the B760M-CT

The B760M-CT is a Micro ATX form factor board measuring 244 x 244mm. It uses an old-school green PCB with a moisture-preventing coating to help in high-humidity environments. Built for business, it’s not meant to be viewed, really. With that in mind, you don’t get any integrated RGBs or RGB headers to add your own. Typical use cases will have these inside chassis without windows anyway. Strictly business here, folks!

Our board tour starts in the upper-left corner, where we find the required 8-pin EPS connector to power the processor. We usually see heatsinks covering the VRMs, but Asus chose to go without, which is acceptable at stock settings, even when using a power-hungry Intel Core i9-14900K.

Above the socket are the first (of three) 4-pin fan headers. Each header supports DC and PWM-controlled devices. Asus doesn’t list power output, so assume it’s 1A/12W – plenty for the type of PC it is on a platform that can’t overclock the CPU and generally won’t use high-powered processors.

Moving right, we hit four DRAM slots with the locking mechanism at the top (the right spot!). Asus lists support for up to 192GB on the specification page. However, in March, they published an article showing that this board (and dozens of others) supports 256GB. Curiously, as of this writing (four months after the article above), they still have not updated this information on each board’s webpage.

Along the right edge is the 24-pin ATX connector to power the board, along with a front panel 19-pin USB 3.1 5 Gbps connector and 5 Gbps Type-C connector.

Power delivery is a 7-phase configuration with five dedicated to Vcore. Power comes from the EPS connector to the OnSemi NCP81270C controller and finally to the five Vcore phases. As you can see from the image, this isn’t an integrated MOSFET, as we’re used to seeing on more expensive boards. The high and low sides are separated with three total ICs per phase. Still, it handled our i9-14900K but was limited to 125W after some time. Temperatures ran hot but did not throttle the VRMs. There’s no way I’d increase the duration or any power limits though, as they are at the limit. But again, this is made for business, and this ecosystem typically won’t change anything except perhaps enable XMP profiles.

On the bottom half of the board, starting on the left, we see a naked audio section based on the Realtek ALC897 codec. Additionally, there are a few audio capacitors. It’s a budget codec but perfectly acceptable for professional use.

In the middle of the board, we spy three PCIe slots and three M.2 sockets. Starting with PCIe, the top slot connects through the CPU, runs up to PCIe 4.0 x16 speeds, and is your primary (only!) location for a discrete video card. Below are two closed-ended PCIe x1 slots running up to PCIe 3.0 x1.

Among the PCIe slots are two Key-M and a Key-E M.2 sockets. Both Key-M slots support up to 80mm modules and PCIe 4.0 x4 devices. SATA-based M.2 is not supported. The Key-E socket, below the PCIe slot, supports CNVi (Wi-Fi card) modules up to 30mm. Wi-Fi is not included. Skipping past the pushpin-connected chipset heatsink are the four SATA ports. The B760M-CT does support RAID on the SATA ports, but not M.2.

Across the bottom is a slew of headers for additional connectivity and security. From left to right, there’s front panel audio, two COM ports, an LPT header, a chassis fan header, and two USB 2.0 headers. Continuing focus to the right are clear CMOS and Debug jumpers, along with speaker, front panel, and chassis intrusion headers.

The rear IO on our business-class motherboard is unique compared to many boards we’ve covered over the past few years. Here, we see more video outputs (four) than we’re used to and far fewer USB ports (also four). You get two DisplayPorts, one HDMI, and one legacy VGA video output to run up to four monitors off the integrated graphics on most Intel CPUs. For USB, there are two 3.2 Gen 1 (5 Gbps) ports and two USB 2.0 (480 Mbps) ports – not a lot. You can use the front panel ports by buying an add-in card or one of the best USB hubs. It also has two PS/2 ports for a mouse and keyboard, the Intel 1 GbE plug, and, for audio, three 3.5mm jacks.
