ECS Boards The Z790 Express

Motherboards, News

Riding under a new IPC badge (, ECS has moved its L337 Gaming Z790H7-A from its month-old fantasy announcement to actual production. Standout features includes its stated ability to support DDR5-4800 long after Intel decided to make DDR5-5600 official on its Z790 platform.

While pictures of the board look fairly bare, large heat sinks on an 18-phase voltage regulator might indicate sleeper status for a high-performing overclocking board. Lacking the knowledge to make an assessment without having the board in hand, we’ve requested a review sample.

The same announcement included details of a B660 Barebones PC, but several of its details appear to be nonspecific “built to order” for distributors. Without specific components lists for specific SKUs, we’re left only with the details of its ECS B660H7-M20 motherboard that will be powered by an unnamed 550W or 650W 80Plus Gold rated power supply being placed in a H 381 x W 209 x D 390mm case.
