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
This configuration provides 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
This option is straightforward, familiar, and suitable for lower-density environments.
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
Customers planning long-term growth or using modern equipment often benefit most from 208V.
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.
- 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).
Choosing the Right Configuration
Your ideal power setup depends on your hardware density, redundancy requirements, and future expansion plans.
- 20A 110V is suitable for simple or low-density deployments.
- 30A 208V is common for modern, dense, or power-hungry systems.
- A+B redundant power is recommended when uptime is critical.
