Alright folks, we have the TUF Gaming B660M-Plus Wi-Fi D4 in for a review. This is an Intel B660 chipset based motherboard with a retail price of ₱11, 730 PHP.

For its price price point, what you’ll get is a Micro-ATX motherboard with full-size features. Notables are the 10+1 DrMOS Power Stages, its PCIe 5.0 support, dual PCIe 4.0 M.2 slots, Intel Wi-Fi 6, Realtek 2.5Gb Ethernet and more. Memory interface is still DDR4 yet with a maximum clock speed support at 5333 MHz.

Disclosure: ASUS sent the TUF Gaming B660M-Plus Wi-Fi D4 for the purpose of this review. The brand did not ask me to say anything particular about it.

The packaging should come with the following items inside:

  • ASUS TUF Gaming B660M-Plus Wi-Fi D4 Motherboard
  • 2x SATA III cable
  • ASUS Wi-Fi moving antenna
  • M.2 Rubber Package
  • M.2 SSD screw package
  • TUF Gaming sticker
  • Support DVD
  • TUF Certification card
  • User guide

Decent bundle of accessories we got here.

Design, Build and Connectivity

The ASUS B660M-Plus Wi-Fi D4 is a Micro-ATX motherboard with huge heatsinks for its power delivery along with a rather tight memory slot clearance – like Mini-ITX tight. This model also comes with the LGA 1700 mounting holes alone. None of the backward compatible hybrids like the one found on this motherboard.

I couldn’t find any fault at the back – like many ASUS motherboards before it. We have a surface mounted PCIe 5.0 x16 slot here along with the PCIe 4.0 x1 and PCIe 3.0 x4 slots.

Up top are a combination of 4 and 8-pin CPU power connectors, 3x 4-pin PWM fan headers and 2x 3-pin LED headers.

ASUS TUF Gaming B660M Plus Wi Fi D4 Images 6

Internal storage ports are plenty enough. We have two SATA headers here, a USB 3.0 header, a USB 3.2 header and of course the 24-pin power connector.

ASUS TUF Gaming B660M Plus Wi Fi D4 Images 5

Usual assortments down below with yet another set of the remaining SATA, fan and LED headers. We also have a Thunderbolt header here.

Rear I/O port selection is just shy of excellence. We have eight USB ports around this area, two display ports, SMA connectors for the WI-Fi 6 adapter and the usual suspects.

ASUS TUF Gaming B660M Plus Wi Fi D4 Images 3

Build and layout are quite nice – although there are things to consider around the CPU socket area. This includes the possible clearance issues and the omitted support for the LGA 1200/115X coolers.

Firmware Interface

ASUS had the TUF Gaming B660M-Plus Wi-Fi D4 configured with their UEFI BIOS Utility. It comes with EZ Mode and Advanced Mode like most motherboard vendors nowadays.

ASUS TUF Gaming B660M Plus Wi Fi D4 BIOS UEFI 1

Ai Tweaker is where you could play with the CPU and memory settings. Like the other brands, ASUS also had their own power limit option here to toggle between Intel and their own. Only memory overlocking is possible here but you could still adjust voltage and current related settings for both the CPU and of course memory.

ASUS TUF Gaming B660M Plus Wi Fi D4 BIOS UEFI 2

Advanced is where the chipset or PCH options could be adjusted. This is where you could setup the TPM, enable Re-Size BAR support, access the storage options and the likes.

ASUS TUF Gaming B660M Plus Wi Fi D4 BIOS UEFI 3

Hardware monitor comes with the usual thermal sensors, fan speed sensors and voltage sensors.

ASUS TUF Gaming B660M Plus Wi Fi D4 BIOS UEFI 5

Tools is where you could securely erase storage and flash your BIOS. Handy features to setup your system for a clean installation.

ASUS TUF Gaming B660M Plus Wi Fi D4 BIOS UEFI 4

Last but not the least we have a screenshot of the Q-Fan Control. Five fans could be configured here each on their own. Sadly, we cannot manually setup the minimum and maximum fan speeds to our desired level.

Nothing to complain here other than the Armoury Crate pop-up even if it is disabled via BIOS. Please fix this ASUS.

Test Setup and Methodology

Our test setup relies on the measurements taken from industry standard benchmark tools and real-world applications. It is important to note that we are testing the review sample after burn-in, with at least 24-hours of uptime. This is done so to negate the FOTB (fresh out the box) state of the DUT (device under test), yielding better benchmarking consistency.

Audio Performance

THD + Noise is measured in Decibels (dBA). This is done via the RightMark Audio Analyzer and its Test Report.

ASUS TUF Gaming B660M Plus Wi Fi D4 Benchmarks 21

Audio performance, like many motherboards nowadays is lacking. Power handling is mediocre too, since it cannot deliver at least 20 mW for my Sennheiser HD600.

Network Performance

Network throughput is measured in Megabits per second (Mbps) at download and upload. This is done via LAN Tester.

ASUS TUF Gaming B660M Plus Wi Fi D4 Benchmarks 22

Wired networking performance is a-okay.

Thermals

VRM temperature is measured in degree Celcius (ºC) at system idle and load. This is done via AIDA64 Extreme and its System Stability Test.

ASUS TUF Gaming B660M Plus Wi Fi D4 Benchmarks 15

The ASUS TUF Gaming B660M-Plus Wi-Fi D4 has the hottest VRM out of the bunch. It is not alarmingly hot.

Power Consumption

System power consumption is measured in Watts (ºC) at system idle and load. This is done via AIDA64 Extreme and its System Stability Test.

ASUS TUF Gaming B660M Plus Wi Fi D4 Benchmarks 16

Now power consumption is decent. Just a tad higher compared to the Mini-ITX motherboard we got.

Features

ASUS had the TUF Gaming B660M-Plus Wi-Fi D4 bundled with the Armoury Crate. I’m not going to dive deep into it since its a pretty much beaten to death feature of ASUS motherboards.

Other than its obvious PCIe 5.0 support, the B660M-Plus comes with Dual PCIe 4.0 M.2 slots with a flexible/interchangeable heatsink. It also comes with Intel’s Wi-Fi 6 module, a Realtek 2.5Gb Ethernet, rear USB 3.2 Gen 2×2 Type-C port, a front USB 3.2 Gen 1 Type-C header, ASUS Aura Sync and Two-way AI Noise Cancelation feature for the microphone.

As a TUF GAMING Alliance motherboard, ASUS ensures its compatibility across a wide range of parts such as PC cases, power supplies, CPU coolers, memory kits and more with the same branding. You may learn more about it here.

Final Thoughts

The ASUS TUF Gaming B660M-Plus Wi-Fi D4 is a good motherboard yet I have a lingering reservation as to why I cannot simply recommend it to just about anyone. Don’t get me wrong, the motherboard aced a lot of our benchmarks considering its DDR4 interface – and with a DDR4-2666 memory kit at that. There are just a few caveats to look out for.

Number one of those would be the price. This motherboard should follow the current retail price of $170 USD, but for some reason, it comes with an over $200 USD street price – locally. I could even see some stores charging up to ₱11, 730 PHP which is a shame. At that price, I also expected a meatier audio solution and backwards compatibility with the last generation coolers. The VRM is also hotter compared to other motherboards we’ve tested.

Luckily, the rest still checks out on a positive note. We have a nice bundle of accessories, good connectivity options and a UEFI that works without a hitch. I’m already recycling a lot of words here from the previous reviews and with that said, I could only see this motherboard as a winner under $200 USD. Still a certified product though at its designated price point of $170 USD.

Summary

The ASUS TUF Gaming B660M-Plus Wi-Fi D4 Motherboard is a rock solid DDR4 platform for the LGA 1700 based microprocessors at $170 USD. Past that, you’d have to look somewhere else.
