Budget PSUs for Office PCs: 2026 Buyer's Guide
This guide focuses on power supply units (PSUs) for basic office PCs, where the primary concerns are low cost and reliable operation for non-demanding tasks. These PSUs are suitable for systems with integrated graphics or very low-power discrete GPUs, basic CPUs, and minimal storage. Users building systems for web browsing, document editing, and email will find suitable options here, prioritizing affordability over high-end features or extreme efficiency ratings.
Featured Picks
## LC1200 V2.4 This unit is an option for those seeking the absolute lowest price point. Its 1200W rating is significantly overkill for any office PC, indicating a likely misrepresentation or a very low-quality internal design. Strengths: Extremely low price at $7.99. Caveats: The 1200W rating for $7.99 is unrealistic and suggests a very low-quality, potentially unsafe product. Not recommended for any system where reliability is a concern.
## PM600D The PM600D offers a more reasonable 600W at a slightly higher price point, making it a potentially more balanced budget choice for basic office systems. Strengths: Low price of $9.64. 600W is ample for most office builds. Caveats: Specific efficiency ratings or safety certifications are not provided, which is common for units in this price bracket. Quality may be inconsistent.
## AX760 At $11.99, the AX760 provides 760W, which is more than sufficient for any office PC configuration. This unit is priced identically to the AX860 and AU-650X. Strengths: 760W provides significant headroom for office use. Still very affordable at $11.99. Caveats: Like other budget units, detailed specifications on efficiency or component quality are often absent. The higher wattage is unnecessary for typical office tasks.
## AX860 The AX860 offers 860W for $11.99, making it one of the highest wattage options in this budget tier. This provides substantial power, though it's largely unutilized in an office environment. Strengths: High 860W capacity for $11.99, ensuring ample power for any office build. Very low cost. Caveats: The 860W is excessive for office PCs, meaning you're paying for unused capacity. Quality and efficiency are likely basic given the price.
## AU-650X With 650W for $11.99, the AU-650X is another option that provides adequate power for office use without being excessively high-wattage. It sits in the middle of the higher-priced budget options. Strengths: 650W is a practical wattage for most office PCs. Affordable at $11.99. Caveats: No specific efficiency or reliability certifications are mentioned, which is standard for this price point. Quality may vary.
For a basic office PC, the PM600D at $9.64 offers a reasonable balance of cost and wattage. If you require slightly more headroom and are comfortable with the $11.99 price, the AU-650X provides a practical 650W. The LC1200 V2.4 should be approached with extreme caution due to its unrealistic specifications and price point.
