Review ASTEC 145w Atx Power Supply Vintage Retro Computing

The ASTEC ATX145-3505 is a 145-watt ATX power supply unit (PSU) designed for use in computers built in the mid-1990s. This PSU is an essential component of a computer system, responsible for converting AC power from an outlet into DC power for the various components inside the computer.

The ATX145-3505 is a 3.3V and 5V SMPS (Switched Mode Power Supply) design, which offers improved efficiency and stability compared to linear power supplies of the time. It features a total of five 12V, two 3.3V, and two 5V rail outputs. The 12V rails can deliver up to 11.83A each, while the 3.3V and 5V rails can deliver up to 1.2A each. This output configuration is suitable for most mid-range desktop systems of the late 1990s.

The dimensions of this PSU are 150mm (L) x 86mm (W) x 46mm (H), making it a standard ATX form factor. It comes with a 20-pin ATX main power connector, two 4-pin 12V auxiliary power connectors, a 5.25-inch floppy disk drive power connector, and various PCI, peripheral, and other connectors to accommodate the various components of a typical desktop computer of the era.

The ATX145-3505 features a semi-modular design, meaning that some of the peripheral connectors are detachable, allowing for easier cable management and reducing clutter inside the computer case. The PSU is also equipped with over-voltage, over-current, and short-circuit protection to safeguard the components from potential damage.

This PSU is a reliable choice for those upgrading or restoring older computers, offering sufficient power output for most mid-range systems and the convenience of a semi-modular design. Its efficient design also ensures that it operates quietly, minimizing the noise that can sometimes be associated with older power supplies.

The ATEC ATX145-3505 is a 145-watt ATX power supply unit (PSU) that was manufactured in 1996. While it may be possible to use this PSU in some older computing systems, it's essential to consider its pros and cons before making a purchase.

Pros:

1. Historical Value: This PSU has historical value as it was manufactured during the early days of the PC era.

2. Availability: It may be easier to find this PSU in the second-hand market compared to newer models.

3. Potential Cost Savings: The price of this PSU is usually lower than that of a new one.

Cons:

1. Limited Power: With only 145 watts of power, this PSU may not be sufficient for modern computing systems.

2. Inefficient: Older power supplies tend to be less efficient than newer models, which could result in increased electricity bills.

3. Compatibility Issues: This PSU may not be compatible with modern hardware, and there's a risk of damaging components if it's used in a system it's not designed for.

4. Safety Concerns: The age of this PSU could potentially make it a safety hazard due to worn-out capacitors or other components.

5. Lack of Modern Features: This PSU does not offer modern features such as modular cabling, active PFC, or quiet operation.

Ending Conclusion:

The ATEC ATX145-3505 145w ATX power supply unit can be an interesting addition to a vintage computing system or a collector's item. However, its limited power, inefficiency, compatibility issues, safety concerns, and lack of modern features make it a less than ideal choice for a modern computing system.

Recommendation:

If you are looking for a power supply for a modern computing system, it is highly recommended that you invest in a newer, more efficient, and reliable model that can meet the power requirements of your hardware. If you're interested in vintage computing, consider purchasing a compatible PSU from a reputable seller or restoring an existing one.
