Review DELTA Power Supply

The **Delta DPS-800AB-37 800W Power Supply** is a high-performance, fully modular, and ultra-efficient unit designed to deliver reliable power to even the most demanding computing setups. Engineered with cutting-edge technology, this power supply stands out as a robust solution for enthusiasts, content creators, and professionals who demand precision, durability, and energy efficiency in their systems. Built with an **800-watt capacity**, it provides ample headroom for high-end gaming rigs, workstations equipped with multi-GPU setups, or high-performance liquid cooling systems, ensuring stable operation even under heavy loads. The **fully modular design** allows users to connect only the cables they need, reducing cable clutter inside the case while improving airflow and maintainability an essential feature for those prioritizing both aesthetics and functionality.

At the heart of this power supply lies **800W of continuous power**, backed by **80 Plus Bronze certification**, which guarantees exceptional energy efficiency with an average of **82% efficiency** across its operating range. This not only translates to lower electricity bills but also reduces heat generation, contributing to a cooler and more stable system environment. The **active PFC (Power Factor Correction)** further enhances performance by minimizing power fluctuations and ensuring smoother operation of connected components. Additionally, the **12V rail is rated for 68.3A**, making it one of the most robust single-rail designs available, capable of handling demanding GPUs and high-end CPUs without sagging or instability.

Safety and reliability are paramount in the Delta DPS-800AB-37, which incorporates **multiple protection mechanisms**, including **over-voltage protection (OVP), over-current protection (OCP), over-power protection (OPP), short-circuit protection (SCP), and over-temperature protection (OTP)**. These safeguards ensure that the power supply operates within safe parameters, preventing potential damage to both the PSU itself and the connected hardware. The unit also features **fanless operation at light loads**, utilizing a **120mm PWM-controlled fan** that spins down to near-silence when the system is under minimal stress, only ramping up when necessary to maintain optimal temperatures. This intelligent cooling system not only extends the lifespan of the fan but also significantly reduces noise levels, making it ideal for silent workstations or home office setups.

Constructed with high-quality components, the Delta DPS-800AB-37 employs **full-bridge topology** for superior efficiency and stability, while its **Japanese-made capacitors** ensure long-term reliability and durability. The modular design includes **individual connectors for GPU, CPU, SATA, and peripheral power**, allowing for a clean and organized build with minimal cable strain. The **black and silver aesthetic** complements modern PC cases, adding a touch of sophistication to any build. Whether used in a high-performance gaming PC, a professional editing workstation, or a server-grade setup, this power supply delivers a perfect blend of power, efficiency, and quiet operation, making it a standout choice for those who refuse to compromise on performance.

### **Pros and Cons of the Delta DPS-800AB-37 (800W) Power Supply**

1. **High Power Output (800W)** Suitable for mid-to-high-end gaming PCs, workstations, or systems with multiple GPUs (if paired with a compatible motherboard). The 800W capacity provides ample headroom for future upgrades.

2. **80 Plus Bronze Certification** Offers decent efficiency (82-85% at nominal load), reducing energy costs and heat generation compared to non-certified units. This is better than many basic power supplies but not as efficient as Gold or Platinum-rated units.

3. **Modular Design (Optional)** The DPS-800AB-37 features semi-modular cables, meaning you can detach power cables from the PSU but cannot remove all unused cables from the unit. This helps reduce cable clutter inside the case while still keeping some flexibility.

4. **Reliable Brand (Delta)** Delta is a well-known manufacturer with a reputation for durability and consistent performance. Their power supplies are often praised for longevity, especially in budget to mid-range tiers.

5. **Active PFC (Power Factor Correction)** Improves power draw from the wall outlet, reducing strain on electrical systems and slightly enhancing efficiency.

6. **Fanless Operation at Low Loads** The PSU remains quiet under light loads, which is beneficial for silent builds or office use.

7. **Good Cooling System** Features a single 120mm fan with a PWM-controlled speed, which helps maintain stable performance under heavy loads.

8. **Widely Available and Affordable** Often found at competitive prices, making it a cost-effective choice for budget-conscious builders.

9. **Compliance with Safety Standards** Meets international safety certifications (such as UL, CE, and CB), ensuring it is safe for general use.

1. **Bronze Efficiency Rating** While better than no certification, 80 Plus Bronze means higher energy consumption and heat output compared to Gold (87-90%) or Platinum (90-92%) units. If energy efficiency is a priority, a higher-rated PSU would be preferable.

2. **Non-Fully Modular** Semi-modular cables mean you still have some unused cables inside the case, which can be less tidy than fully modular units. While better than non-modular, it may not appeal to users who prioritize cable management.

3. **Limited Warranty (Typically 5-7 Years)** Most Delta PSUs come with a standard 5-year warranty, which is average but not exceptional compared to some competitors offering 10-year warranties (e.g., Corsair, EVGA).

4. **No Overkill for High-End Systems** An 800W PSU is overkill for most gaming PCs unless you are running dual GPUs (e.g., RTX 4090 RX 7900 XTX) or a high-end CPU with heavy cooling. For single-GPU builds, a 650W 750W PSU is often sufficient, and a higher-efficiency unit would be more cost-effective long-term.

5. **Fan Noise Under Heavy Load** While the fan is PWM-controlled, it may become noticeable under sustained high loads, especially in smaller cases where airflow is restricted.

6. **No RGB or Aesthetic Features** If you prefer PSUs with RGB lighting or customizable features, this unit lacks those extras.

7. **Potential for Higher Temperatures** Bronze efficiency units tend to run warmer than Gold/Platinum-rated ones, which could be a concern in poorly ventilated cases.

8. **Limited Customization Options** Unlike some high-end PSUs, this model does not offer features like fan speed control via software or additional connectors (e.g., extra SATA or PCIe power).

The **Delta DPS-800AB-37 (800W)** is a solid, reliable power supply that excels in durability and affordability. It is well-suited for mid-range gaming PCs, workstations, or systems where future GPU upgrades are planned. The Bronze efficiency rating means it is not the most energy-efficient option, but it performs adequately for most users. The semi-modular design helps with cable management, and Delta s reputation for longevity makes it a trustworthy choice.

However, if energy efficiency is a priority, a **Gold or Platinum-rated PSU** (e.g., Corsair RM850x, EVGA SuperNOVA 850 G6) would be a better long-term investment. For single-GPU builds, a **650W 750W PSU** with higher efficiency would be more than sufficient and cost-effective. If you are building a high-end system with dual GPUs or a powerful CPU, the 800W capacity is justified, but ensure the rest of your components can handle the wattage.

---

- You need an **800W PSU** for dual-GPU setups or high-end builds.

- You prioritize **reliability and budget-friendly pricing**.

- You are okay with **Bronze efficiency** and don t mind slightly higher energy consumption.

- You prefer a **semi-modular design** for easier cable management.

- You want **better efficiency** (Gold/Platinum-rated PSUs like Corsair RM850x or EVGA SuperNOVA 850 G6).

- You are building a **single-GPU system** and could get away with a **650W 750W PSU**.

- You want **longer warranties** (e.g., 10-year models from Corsair or EVGA).

- You prefer **fully modular cables** for maximum tidiness.

For most **single-GPU gaming PCs**, a **650W 750W Gold-rated PSU** (e.g., Corsair RM750e, Seasonic Focus GX-750) would be a better balance of efficiency, cost, and performance. The Delta DPS-800AB-37 is a **good choice for those needing higher wattage or a no-frills, reliable PSU**.
