### **Pros and Cons of buying a Delta DPS-600SB-D for QNAP TS-1279U-RP/TS-1679U-RP**

#### **Pros**

1. **Redundancy and Reliability** The DPS-600SB-D is a hot-swappable, redundant power supply designed to prevent downtime in case of a single unit failure. This is critical for NAS units that store important data, as it ensures continuous operation even if one PSU fails.

2. **High Efficiency (80 Gold Certified)** The unit operates at high efficiency (up to 90% at full load), reducing energy waste and heat generation. This helps lower electricity costs and extends the lifespan of the NAS and other components.

3. **Hot-Swap Capability** The ability to replace a faulty PSU without powering down the NAS is a significant advantage, minimizing data loss risks and operational disruptions.

4. **Quiet Operation** Delta PSUs are known for being relatively quiet, which is beneficial for home or office environments where noise levels matter.

5. **Compatibility with QNAP TS-1279U-RP/TS-1679U-RP** The DPS-600SB-D is officially supported by QNAP for these models, ensuring proper voltage regulation and compatibility with the NAS s power requirements.

6. **Durability and Build Quality** Delta is a reputable brand with a strong track record in power supply manufacturing, offering robust construction and long-term reliability.

7. **Warranty and Support** The unit typically comes with a warranty (often 5 years or more), providing peace of mind against premature failure.

#### **Cons**

1. **Higher Upfront Cost** A redundant PSU is significantly more expensive than a single PSU. For a NAS that may not experience frequent power issues, this added cost may not be justified unless redundancy is a critical requirement.

2. **Space Constraints** The TS-1279U-RP and TS-1679U-RP already have limited internal space. Installing a redundant PSU may require careful cable management or potentially external mounting, which could complicate setup.

3. **Overkill for Low-Risk Environments** If the NAS is located in a stable power environment with minimal risk of outages or PSU failure, the redundancy may be unnecessary, making a single PSU a more cost-effective choice.

4. **Potential for Redundancy Overlap** Some NAS users report that the redundant PSU in these models may not always be fully utilized, as QNAP s firmware sometimes defaults to a single PSU for efficiency, reducing the benefit of redundancy.

5. **Limited Availability and Compatibility Checks** While the DPS-600SB-D is officially supported, it s important to verify that no firmware updates or future NAS models may require different PSU specifications. Always check QNAP s latest compatibility lists before purchasing.

### **Conclusion**

The **Delta DPS-600SB-D is an excellent choice** for users of the **QNAP TS-1279U-RP/TS-1679U-RP** who prioritize **data integrity, uptime, and redundancy**. Its hot-swap capability, high efficiency, and reliability make it a strong investment for environments where power stability is critical such as home offices, small businesses, or data-sensitive applications.

However, if **budget is a concern** or the NAS operates in a **stable power environment with minimal failure risks**, a single PSU (or even a third-party redundant unit if available at a lower cost) might suffice. Always weigh the cost against the potential consequences of a power failure before deciding.

### **Recommendation**

- You cannot afford any downtime (e.g., critical data storage, business use).

- Your power supply is unreliable (frequent outages, poor infrastructure).

- You want long-term reliability and efficiency.

- You are on a tight budget and can accept the risk of a single PSU.

- You plan to use the NAS in a stable environment with minimal power issues.

- You find a similarly rated redundant PSU (e.g., from Corsair or Seasonic) at a lower price.

For most users who value **data safety and redundancy**, the **Delta DPS-600SB-D is a strong and justified purchase**. Just ensure proper installation and cable management to avoid any space-related complications.
