About This Product
The CoolMax CUL-650B is a 650W semi-modular ATX power supply. It is suitable for entry-level to mid-range gaming PCs or general-purpose workstations that do not demand high power efficiency or advanced features. Its semi-modular design offers some cable management flexibility compared to non-modular units, but it lacks the full modularity found in higher-priced alternatives.
Verdict
“Consider for budget builds needing 650W and basic cable management, if reliability is not a primary concern.”
