Hardware specifications and design

It’s obvious right from the start that the ASUS ROG Crosshair X670E Hero is a high-end motherboard. Just one look at it reveals the attention to detail invested by the company’s engineers and hardware designers. There are large plates and heatsinks covering all the essential parts, and they’re not there just to make the motherboard look beautiful but also to help deliver outstanding performance.

The motherboard looks great and has large heatsinks

What instantly impressed me when I unpacked this motherboard was the massive heatsinks covering the voltage regulator module (VRM) and the main M.2 PCIe 5.0 solid-state drive slot. Their height and weight are more than I’ve seen on any AM4 mainboard, and that’s great as it means that the ROG Crosshair X670E Hero is built to withstand even the most powerful and energy-hungry AMD Ryzen 7000 processor. That includes the top-of-the-line Ryzen 9 7950X, which can draw almost 200 Watts without even overclocking it!

The VRM is covered by huge heatsinks

The power required by the motherboard and processor is delivered via three EPS connectors: a standard 24-pin ATX main power connector next to the DIMM slots and two 8-pin connectors positioned on the top-left corner of the mainboard. Additionally, right under the 24-pin ATX power connector, there’s another special 6-pin connector that you can use to deliver more power to your PCIe x16 slot (up to 60 Watts).

Motherboard power connectors

As the ASUS ROG Crosshair X670E Hero is designed for the brand new AMD Zen 4 processors, it uses the (also new) AM5 socket. This socket is not compatible with older AMD processors from the Ryzen 5000 or Ryzen 3000 families. The only CPUs you can mount today are the AMD Ryzen 9 7950X, Ryzen 9 7900X, Ryzen 7 7700X, and Ryzen 5 7600X.

In terms of memory compatibility and options, the ASUS ROG Crosshair X670E Hero supports only DDR5 and comes with four DIMM slots that can house a maximum of 128 GB of RAM. By default, the DIMM slots can run at default frequencies of 4800 up to 5600 MHz (in increments of 200 MHz). However, the motherboard can also use AMD EXPO-enabled memory which can run at 5800, 6000, 6200, 6400 MHz, and even faster.

While the X670E chipset inside the ROG Crosshair X670E Hero motherboard offers support for PCI Express 4.0, you also get PCI Express 5.0 via the processor lanes. The x16 slots (x16 or x8/x8) plus two M.2 SSD slots (x4) run on PCI Express 5.0.

Then, there’s one x1 slot that uses PCIe 4.0, two additional M.2 SSD slots (x4) that support PCIe 4.0, and six SATA 6Gb/s ports.

There are many M.2 SSD slots available on the motherboard

The motherboard also bundles a PCIe 5.0 M.2 card that you can use to add a fifth PCIe 5.0 SSD (x4); however, if you plug it into the second PCIe x16 slot, the first one will run in x8 only.

Connectivity-wise, the motherboard doesn’t cut any corners. You get an Intel 2.5 Gb Ethernet card with ASUS LANGuard (protection against power spikes and fewer data transmitting errors). In addition, you also get 2x2 Wi-Fi 6E that supports the 2.4, 5, and 6 GHz frequency bands, plus support for Bluetooth 5.3.

For the audio part, you get ASUS’ ROG SupremeFX 7.1 Surround Sound High Definition Audio CODEC ALC4082. It supports stereo playback at up to 32-bit/384 kHz and up to 120 dB SNR (Signal-To-Noise ratio), 113 dB SNR recording input.

Besides network and audio ports, on the I/O panel, you also get two USB4 Type-C ports (Intel JHL8540), one USB 3.2 Gen 2x2 Type-C port, nine USB 3.2 Gen 2 ports (8 are Type-A and one is Type-C), and an HDMI port. Oh, and you also have a BIOS FlashBack and a Clear CMOS button.

In terms of fans and cooling, the motherboard includes many connectors: one 4-pin CPU fan header, one 4-pin CPU OPT fan header, one 4-pin AIO pump header, four 4-pin chassis fan headers, one W_PUMP+ header, one 2-pin Water In header, one 2-pin Water Out header, and one 3-pin Water Flow header. There are also additional USB headers available: one USB 3.2 Gen 2x2 connector (supports USB Type-C), two USB 3.2 Gen 1 headers (support four additional USB 3.2 Gen 1 ports), and three USB 2.0 headers (support six additional USB 2.0 ports).

The bundle of headers is generous

If you’re a fan of RGB lighting effects, in addition to the Polymo Lighting effects on the motherboard itself, you also get one Aura RGB header and three addressable Gen 2 headers.

You get a lot of USB headers, SATA ports, and fan headers
