It’s ANSI/EIA RS-310-D compliant and easy to implement in most 19″ racks.
Best for: Small to medium racks needing reliable surge protection and straightforward 1U mounting without excessive rear/outlet complexity.
Caution: The 6-foot cord may be short for some larger rack layouts; plan cord routing before installation.
CENTROPOWER 1U Horizontal PDU: 10 Outlets
The CENTROPOWER 1U PDU offers 10 NEMA 5-15R outlets with a 6-foot cord, designed for 19″ server racks 4 inches deep or deeper. Its horizontal layout helps maximize rack real estate, and the unit is described as fireproof housing with heavy-duty construction intended for long life. This option balances cost with essential power distribution needs for network closets and small data setups.
Best for: Budget-conscious users who need a 1U, 10-outlet PDU compatible with standard 19″ racks and looking for straightforward installation.
Limitation: The description emphasizes basic protection; verify surge specs fit your equipment’s sensitivity and consider additional protection if you have high-value gear.
ElecVoztile 8-Outlet Rack Mount PDU
This 1U PDU supports eight outlets with 125V/15A capacity and features a built-in 1020J surge protection module. Its heavy-duty aluminum housing is designed for robust performance in racks, servers, and network gear environments. The unit includes an overload and reset switch for quick power management, making it suitable for dense equipment layouts where surge protection and reliability are priorities.
Best for: Environments needing strong surge protection within a compact 1U footprint, including network closets and small data centers.
Caution: Aluminum housings, while durable, can require careful handling to avoid cosmetic damage during installation in crowded racks.
CyberPower CPS1215RMS Surge Protector
The CyberPower CPS1215RMS provides twelve NEMA 5-15R outlets across a 1U rackmount footprint, with a 15-foot power cord and a 1U rackmount design that supports vertical or horizontal installation. This PDU offers essential power protection for data centers, network closets, and VoIP systems, helping safeguard sensitive equipment from power irregularities while maintaining organized rack wiring.
Best for: Users needing a flexible mounting option (vertical or horizontal) with a straightforward 12-outlet design and extended cord length for larger rack layouts.
Caution: The description focuses on protection and layout rather than advanced conditioning; ensure it aligns with your power quality requirements for critical gear.
Buying Guide: Rack Mount Power Strips — Key Considerations
- Outlet count and arrangement: Decide how many devices must plug in and whether you need front, rear, or both access. Front outlets are convenient for hot swappable gear; rear outlets help with tidy cable management.
- Cord length and plug type: Longer cords offer flexibility in larger racks but require careful management. Confirm the plug type matches your region and power standards (15A in most US deployments).
- Surge protection and energy conditioning: Look for surge energy ratings (joules) and indicators for protection status. For sensitive gear, higher joule ratings and robust protection matter more.
- Mounting style and compatibility: Ensure the PDU is compatible with your 19″ rack depth and mounting rails. Horizontal 1U PDUs fit most standard racks; some models support vertical installation for flexible layouts.
- Build quality: Metal housings generally offer durability and longevity, while plastic shells may be lighter but less rugged in busy data centers or AV setups.
- Additional features: On/off switches with locking covers, circuit breakers, LEDs, and reset capabilities can improve safety and reliability in busy or shared environments.

Frequently Asked Questions
- What is a rack mount PDU and why do I need one?
A rack mount PDU distributes electrical power to multiple devices in a 19″ rack, helping tidy cables, protect equipment, and prevent circuit overload by providing multiple outlets with surge protection.
- Should I prioritize more front outlets or rear outlets?
Front outlets improve accessibility for easy device changes; rear outlets help maintain a clean front display in crowded racks. A mix (front and rear) is often ideal for larger setups.
- Is surge protection necessary for all equipment?
For servers, network gear, and VoIP systems, surge protection reduces risk from power spikes. Choose a unit with adequate joule rating for your equipment’s sensitivity and criticality.
- What depth should I consider for 19″ racks?
Most standard racks support 18 to 31 inches in depth. Ensure the PDU depth fits within your cabinet or rack enclosure to avoid clearance issues.
- Can PDUs be mounted vertically, horizontally, or both?
Many 1U PDUs support both orientations, offering flexibility to fit different rack layouts and cable management strategies.
- How long should the cord be for a 19″ rack?
Long cords (around 6 to 15 feet) help span larger racks, but longer cords require careful routing to maintain airflow and reduce clutter.
