What it is
Average grade from independent test sites, magazines and video reviewers, 1–10.
How we count it
Grades: Each review's own score is converted to 1–10; without one, we grade the review ourselves. Big test sites count more, short reviews half as much as full tests. A video review counts half.
Score: The average grade is 80% of the review mark; the number of reviews is the other 20% (1 review = 5, the typical number in this category = 8, the most-reviewed model = 10).
Enough data: With few reviews, the average grade is pulled toward the typical grade of this category. No reviews yet: 7.8 for now.

What customers like about BIOSTAR Z790A-Silver

  • Competitive pricing compared to other Z790 boards
  • Supports high-speed DDR5 memory up to 7200 MT/s
  • Features a PCIe 5.0 x16 slot for future-proof GPU support
  • Ample storage options with three M.2 Gen4 slots and six SATA III ports
  • Solid power delivery (90A Dr. MOS) capable of handling i9-13900K at stock settings
  • User-friendly 'EZ Mode' BIOS interface
  • Includes a dedicated BIOS update button on the rear I/O

What customers don't like about BIOSTAR Z790A-Silver

  • No integrated Wi-Fi or Bluetooth (requires separate M.2 card)
  • VRM heatsinks are basic and can get very hot under heavy multi-threaded loads
  • Limited overclocking headroom compared to high-end competitors
  • Lacks a pre-installed I/O shield and rear backplate
  • Uses the older Realtek ALC1220 audio codec instead of newer versions
  • Poor availability in certain regions, specifically the United States
  • Design is perceived as very basic or 'budget' for a Z790 chipset board

Verdict

The Biostar Z790A-SILVER is an ATX motherboard built on the Intel Z790 chipset, supporting 12th, 13th, and 14th Gen Intel Core processors and up to 192GB of DDR5 memory at speeds exceeding 7200MHz (OC). Key features include a robust 17-phase digital VRM with 90A Dr. MOS, a primary PCIe 5.0 x16 slot with Iron Slot Protection, three PCIe 4.0 M.2 slots for high-speed storage, and 2.5GbE LAN connectivity. Its main advantages are a budget-friendly price point for the Z790 platform, solid overclocking potential for mainstream users, and a dedicated M.2 Key-E slot for adding a WiFi card. However, notable drawbacks include the lack of built-in WiFi/Bluetooth, a relatively basic cooling system for high-end CPU overclocking, and an older Realtek ALC1220 audio codec.
