Pros & Cons
👍 Pros
- 80 Plus Gold 500W PSU delivers certified high efficiency, reducing wasted power and operating costs in continuous-duty rack deployments
- Up to 256GB memory capacity provides a generous ceiling for virtualization and memory-intensive server workloads
- Integrated ASMB4-iKVM module enables full out-of-band remote management without purchasing a separate management card
- EPU energy-efficiency technology dynamically adjusts power consumption to match actual system load
- Barebone configuration allows precise component selection — useful when you have specific processor or storage requirements
👎 Cons
- Barebone format means additional procurement cost and effort — processors, RAM, and drives must all be sourced and installed separately before the server is operational
- The RS500A-E6 targets the AMD G34 Opteron 6000 platform, which is a previous-generation architecture with limited new processor availability
- Single 500W PSU provides no power redundancy — a PSU failure means downtime, which is a significant limitation for production environments
- Published feature listing from ASUS provides minimal technical detail, requiring additional research to confirm specific slot counts, expansion options, and I/O configuration
- As an older platform entry, long-term firmware and software support from ASUS may be limited
Frequently Asked Questions
What does "barebone" mean for this server — what is and isn't included?
Barebone means the chassis, motherboard, and power supply are included, but processors, RAM, and storage drives are not. You supply and install your own CPUs, memory, and drives to build out the configuration you need.
What processor socket does the RS500A-E6 use?
The RS500A-E6 is built on AMD's G34 platform, supporting AMD Opteron 6000-series processors. This is an older AMD server platform — verify socket and CPU compatibility before sourcing processors.
How much RAM can this server support?
The RS500A-E6/PS4 supports up to 256GB of memory, giving you substantial headroom for virtualization workloads once populated.
What is ASMB4-iKVM and why does it matter?
ASMB4-iKVM is ASUS's integrated remote management module — it provides out-of-band access to the server via a dedicated network port, allowing you to remotely monitor hardware health, access the BIOS, and manage the server even when the OS is unresponsive.
What does the 80 Plus Gold power supply rating mean in practice?
80 Plus Gold certification means the PSU operates at 87–92% efficiency under typical loads. Compared to a Bronze-rated supply, a Gold-rated 500W PSU wastes measurably less power as heat — a meaningful difference in 24/7 rack operation over months and years.
