This guide focuses on extremely budget-friendly power supply units (PSUs) for gamers looking to build or upgrade a system on a very tight budget. These options prioritize low cost above all else, offering basic functionality for systems that do not demand high efficiency or advanced features. They are suitable for entry-level gaming PCs with modest power requirements, where every dollar saved counts.
For those seeking the absolute lowest price point, the LC1200 V2.4 is available at $7.99. This ATX form factor PSU boasts a surprisingly high 1200W wattage, which is far more than most budget gaming systems will ever need.
The PM600D offers a more balanced approach for budget builders at $9.64. With 600W of power, it's a practical choice for many entry-level to mid-range gaming setups.
The AX760, priced at $11.99, provides a substantial 760W of power. This unit offers a good balance between wattage and cost for budget-conscious gamers.
Also priced at $11.99, the AX860 delivers 860W of power, making it one of the higher wattage options in this budget tier.

The AU-650X, available for $11.99, provides 650W of power, a common sweet spot for many gaming PCs.
Decision Helper: For the absolute cheapest build, the LC1200 V2.4 is unmatched in price, but its quality is a significant unknown. For a more practical wattage at a still incredibly low price, the PM600D is a good starting point. If you need more power for a slightly more demanding GPU or future upgrades, the AX760, AX860, or AU-650X all offer good wattage for $11.99, with the AX860 providing the most headroom. Always prioritize a PSU with at least basic protection features, even in this budget tier.
