Review ASTEC Power Supply 145w Atx 20-pin 4x Molex

The **AsteC SA147-3505** is a robust and efficient **145-watt ATX power supply** designed to deliver reliable performance for mid-range desktop systems, gaming setups, and small workstations. Built with a **20-pin main connector** and **four Molex connectors**, this power supply is well-suited for systems requiring moderate power demands while maintaining compatibility with a wide range of motherboards and peripherals. Its **145-watt capacity** ensures stable operation for entry-level to mid-tier CPUs, GPUs, and storage solutions, making it an excellent choice for users seeking a budget-friendly yet dependable power source without sacrificing quality.

Constructed with **high-quality components**, the AsteC SA147-3505 features a **fully modular design**, allowing users to connect only the necessary cables, reducing cable clutter and improving airflow within the case. This modularity enhances both aesthetics and efficiency, as excess cables are eliminated, minimizing heat buildup and improving system cooling. The power supply operates at a **single 12V rail**, which, while not as robust as multi-rail designs, provides sufficient current for most standard configurations, ensuring stable voltage delivery to connected components.

Safety and reliability are prioritized in the AsteC SA147-3505, as it includes **overvoltage protection (OVP), overcurrent protection (OCP), and overpower protection (OPP)** to safeguard both the power supply and connected hardware from potential damage due to electrical surges or faults. Additionally, it incorporates **short-circuit protection (SCP)** and **over-temperature protection (OTP)**, further enhancing its durability and longevity. The unit is **fan-cooled**, featuring a **120mm sleeved fan** that operates quietly at lower loads while ramping up efficiency under heavier workloads, ensuring consistent performance without excessive noise.

Ideal for **budget-conscious builders, small form-factor (SFF) cases, or systems with limited power requirements**, the AsteC SA147-3505 strikes a balance between affordability and functionality. Its **compact form factor** makes it a versatile option for users upgrading older systems or those working with space-constrained builds. While it may not be suitable for high-end gaming rigs or workstations with demanding GPUs, its **reliable power delivery, modular flexibility, and protective features** make it a practical choice for everyday computing needs. Whether powering a home office setup, a gaming PC, or a media center, this power supply offers a dependable foundation for smooth and efficient operation.

The Asteck SA147-3505 is a 145W ATX power supply designed for basic systems, particularly older or low-power builds. Below is a detailed breakdown of its pros and cons, followed by a conclusion and recommendation.

1. **Affordability** The power supply is very budget-friendly, making it accessible for users on a tight budget or those building simple systems.

2. **Basic Functionality** It meets the minimum requirements for older PCs, low-power systems, or systems with minimal components (e.g., a CPU, RAM, and a single low-power GPU or no GPU).

3. **ATX Form Factor** Compatible with standard ATX motherboards, ensuring broad compatibility with older builds.

4. **4x Molex Connectors** Sufficient for basic peripherals like hard drives or optical drives, though modern systems may require additional SATA power connectors.

5. **20-Pin Main Connector** Standard for most ATX motherboards, though newer ones may require a 24-pin connector (this unit lacks a 24-pin adapter, which could be an issue for some builds).

6. **Lightweight and Compact** Suitable for small cases or builds where space is limited.

1. **Low Wattage** At only 145W, it is severely underpowered for modern systems. Even a basic CPU (e.g., Intel i3 or AMD Ryzen 3) with integrated graphics and minimal RAM will likely exceed its capacity, leading to overheating or instability.

2. **Lack of Modularity** Non-modular design means cables are permanently attached, which can complicate cable management in tight builds.

3. **No 24-Pin Connector** Most modern motherboards require a 24-pin connector, and this unit only provides a 20-pin. While some motherboards can work with a 20-pin adapter, this is not guaranteed and may void warranties.

4. **No Active PFC (Power Factor Correction)** While not critical for basic use, active PFC improves efficiency and reduces power draw, which this unit lacks.

5. **Limited Longevity** The low wattage and lack of modern efficiency standards (e.g., 80 Plus certification) mean it will struggle with even slightly demanding setups and may not last long if pushed beyond its limits.

6. **No Overvoltage/Undervoltage Protection** Cheaper units like this often lack robust protection features, increasing the risk of damage to components if there are power fluctuations.

7. **No Fan or Cooling** Some ultra-low-power PSUs are passive (no fan), but this one likely relies on a small, noisy fan that may struggle to keep temperatures in check under load.

The Asteck SA147-3505 is a **highly limited and outdated** power supply best suited only for the most basic, low-power systems such as retro builds, educational projects, or emergency repairs where no other option is available. It is **not recommended** for any modern or even moderately demanding PC. The lack of a 24-pin connector, low wattage, and absence of modern efficiency features make it unsuitable for safe or reliable operation in any real-world scenario beyond the most minimalist setups.

If you need a power supply for a **modern or even older but functional PC**, avoid this unit entirely. Instead, consider the following alternatives based on your needs:

- A **200W 300W non-modular or semi-modular PSU** with a 20/24-pin adapter (e.g., Rosewill HX-350, EVGA 400W 80 White).

- Ensure it has a 4x Molex connector if you need legacy peripherals.

- A **400W 450W 80 Bronze or better PSU** (e.g., Corsair CX450, Seasonic Focus GX-450).

- Prioritize a **24-pin connector** and sufficient rail capacity (20A on the 12V rail).

- **Avoid anything below 500W** for even mid-range systems. Look for **80 Gold or Platinum** efficiency ratings and modular cables for better airflow.

If you are working with **extremely limited funds** and have no other option, this PSU *might* work for a **single-board computer (Raspberry Pi, etc.) or a dead-simple setup**, but it is not a reliable choice for anything else. Always prioritize safety and compatibility over cost in PC builds.
