About This Product
The CoolMax CX-400B is a 400W non-modular ATX power supply. It is suitable for basic systems with low power demands, such as office PCs or entry-level gaming builds without a dedicated graphics card. Its non-modular design means unused cables will occupy space within the case, which can affect airflow and aesthetics compared to modular units.
Verdict
“This PSU is best for budget-conscious users building very basic, low-power systems.”
