Pros & Cons
Pros
- ✓ AM3+ socket ready for AMD FX and late Phenom II CPUs
- ✓ ASUS EPU moderates power draw in real time by PC load
- ✓ USB 3.0 onboard at 4.8Gbps, 10x USB 2.0 transfer speed
- ✓ Turbo Key gives a one-touch overclock without a BIOS trip
Cons
- ✗ AM3+ is an end-of-life socket with no new CPU releases
- ✗ Core Unlocker results vary by chip; unlocked cores may be unstable
- ✗ Turbo Key overclocking is coarser than manual BIOS tuning
- ✗ AI Suite II utilities are Windows-only, no Linux equivalent
Manufacturer description
Its headline feature is ASUS EPU, an Energy Processing Unit that reads current PC loading in real time and moderates power delivery to critical components, so an always-on retro or secondary rig draws less at idle. USB 3.0 onboard moves data at up to 4.8Gbps, roughly ten times USB 2.0 throughput, with backward compatibility for older USB 2.0 drives and peripherals. For tuning, Turbo Key gives you a touch-and-boost overclock without a BIOS trip, while Core Unlocker attempts to enable dormant cores on supported AMD chips. Anti-Surge acts as a full-time power guardian, watching for voltage…
SpecPicks Verdict
SpecPicks scored ASUS AM3 Plus Motherboard using a rating × review-volume × price-fit model applied to published specs and reviews across the motherboards category. Compare with similarly-priced alternatives in the motherboards category before committing. Judge it on the specification table and the price rather than on sentiment: check the figures that decide your use case, then put it side-by-side with two or three close alternatives in the Compare tool before clicking through.
Common buyer scenarios for motherboards of this kind: matching it to an existing build, replacing a failing part, or upgrading from a previous-generation equivalent. Check the spec table below against your current setup — particularly socket / form-factor / power-rating fields — and confirm compatibility on the retailer's listing before purchase.

Frequently Asked Questions
What CPUs does this ASUS motherboard support?
It is AM3+ CPU support ready, covering AMD Socket AM3+ processors. Confirm your exact chip against the ASUS CPU support list for this model before buying, since BIOS revision matters on AM3+ boards.
Does this board have USB 3.0?
Yes. It includes USB 3.0 at up to 4.8Gbps, about ten times faster than USB 2.0, and it stays backward compatible with USB 2.0 drives and peripherals.
What does ASUS EPU actually do?
EPU, the Energy Processing Unit, detects current PC loading and moderates power usage to critical components in real time, trimming consumption when the system is not under load.
How do Turbo Key and Core Unlocker work?
Turbo Key is a touch-and-boost overclock trigger, and Core Unlocker attempts to enable dormant cores on supported AMD processors. Both are exposed through the ASUS AI Suite II interface in Windows.
