Ultra-Quiet PSUs 300W to 500W


This range of power supplies are ideal for systems that do not consume a large amount of power. Systems that are designed for word processing, internet browsing and/or general desktop work will benefit from a PSU within this range. These PSUs will also be able to power a gaming PC that does not have a high-end graphics card.
