Rack and Power Requirements Builder
Calculate your total IT load, rack count, recommended power configuration and space requirements before approaching operators. Enter your inputs and get a deployment summary.
Your deployment
Standard 1U servers: 200 to 400 W. GPU servers: 1,000 to 5,000 W.
Standard air cooling: under 20 kW. Enhanced air (in-row): 20–40 kW. Liquid cooling: above 40 kW.
Deployment summary
12.0 kW
Total IT load
13.8 kW
Design load (with redundancy)
2 racks
Rack count
3 m²
Est. gross floor area
Floor area includes hot and cold aisles (600 mm × 1,200 mm cabinet, ~2× gross multiplier — planning estimate). Net cabinet area only: 1.4 m².
Power specification
Power feed sized at 80% of breaker rating — standard electrical design practice (IET Wiring Regulations). This is a planning convention, not a statutory requirement.
Recommended configuration
Dual UPS (N+1), dual A+B power feeds per rack. Each feed sized for full load.
How to use these figures
The outputs from this tool give you a specification to take to colocation providers when requesting quotes. When approaching operators, you should specify your total IT load in kW, your rack density requirement in kW per rack, your redundancy requirement, and your target power feed specification.
Most operators will require a minimum commitment period and will quote based on your power draw, rack count and specific requirements. Having these figures ready before initial contact shortens the sales cycle considerably and signals to the operator that you know what you need.
If your density exceeds 20 kW per rack, use the AI Readiness and GPU Colocation Checker to assess whether you need facilities with enhanced cooling capability.
