Flexible, scalable, and reliable power for growing infrastructure
Reliable power delivery is essential for maintaining stable and efficient systems. Different hardware profiles require specific electrical configurations, and choosing the right setup helps ensure uptime, performance, and room to expand. Our colocation facility offers multiple circuit and voltage options so you can match your rack’s capacity to your deployment.
20A vs. 30A Circuits
20 Amp Circuits
A 20A circuit is ideal for modest or predictable power needs. These circuits typically support:
- Standard 1U and 2U servers
- Small network appliances
- Low-to-medium density deployments
- Environments with lightweight or consistent power draw
A cost-effective entry point for customers with lighter hardware requirements.
30 Amp Circuits
A 30A circuit provides significantly more capacity and flexibility, supporting higher-density or variable-load hardware including:
- Multi-server racks or blade chassis
- High-performance compute nodes
- Large storage systems
- GPU-accelerated or power-intensive servers
The additional headroom reduces the risk of tripping limits during peak demand and accommodates future hardware growth.
110V vs. 208V Power
110V (120V) Circuits
110V power is widely compatible and works well for traditional server and networking equipment. It is appropriate when:
- Your hardware ships with standard 110V power supplies
- You are deploying older or mixed-generation systems
- Your power demand does not require higher-voltage delivery
Straightforward, familiar, and what every Cyber Wurx plan runs on by default — Node, Core, Edge, and the lower Apex power tiers are all 110V.
208V Circuits
208V power is the preferred choice for modern datacenter infrastructure, offering improved efficiency and better support for dense or high-draw systems. Advantages include:
- Higher available power with lower current draw
- Improved efficiency for enterprise-grade PSUs
- Ideal for HPC nodes, virtualization hosts, and GPU-heavy deployments
Available on our Apex plans’ top “Big Power” tier (30A/208V, up to 10kW) — it isn’t offered as a standalone option below Apex.
A+B Redundant Power
Maximum Uptime With Dual Independent Power Paths
An A+B configuration provides two independent power circuits to your rack. When used with dual-PSU equipment, each power supply connects to a different feed, ensuring continuous operation even if one circuit experiences an outage or requires maintenance. It’s especially valuable for:
- Mission-critical applications
- Clusters and virtualization hosts
- High-availability deployments
- Any environment requiring maximum fault tolerance
Each circuit is capable of carrying the full load independently, protecting your equipment from breaker trips, upstream failures, or PDU issues. Systems with single PSUs can still utilize an A+B setup through an automatic transfer switch (ATS). A+B redundancy is available as an add-on on our Apex plans (Full Cabinet or Multi-Cabinet) — it’s one of the advantages of stepping up to a full cabinet, since it isn’t offered on our shared or partial-cabinet tiers (Node, Core, and Edge).
Choosing the Right Configuration
Your ideal power setup depends on your hardware density, redundancy requirements, and future expansion plans.
At a Glance
- Node, Core, and Edge run on a standard shared or single-feed 30A/110V circuit — a straightforward, cost-effective fit for simple or lower-density deployments.
- Apex’s entry power tiers step up to a dedicated 20A/110V circuit, with the top “Big Power” tier reaching 30A/208V for dense, high-draw systems.
- A+B redundant power is available as an add-on on Apex plans when uptime is critical — it’s one of the reasons customers choose a full cabinet (or larger) over a shared or partial-cabinet plan.
