NZXT C-Series C650 Modular ATX PSU

The total electrical power that a device consumes or delivers, expressed in watts (W). It represents the overall energy usage of the product during operation and is useful for comparing efficiency, sizing power supplies, and estimating operating costs.

The total electrical power supplied to the +5 V standby rail of a device, expressed in watts (W). It indicates how much energy is available for low‑power components that remain active when the main system is powered down or in standby mode.

The electrical power supplied to the device’s combined –12 V rail, expressed in watts (W). It indicates how much energy is available on that specific voltage line for components such as fans or auxiliary circuits.

The highest electrical current that a device can supply from its +3.3 V rail, expressed in amperes (A). This value indicates the maximum load capacity of the power supply or regulator for components powered at 3.3 V and helps users verify compatibility with devices requiring this voltage level.

The highest electrical current that a device can supply to its +5 Vsb power rail under normal operating conditions. This value indicates the maximum load the +5 Vsb output can handle and helps users verify compatibility with components such as fans, LEDs, or other peripherals that draw power from this rail.

The highest electrical current that a device can deliver from its –12 V rail under normal operating conditions, expressed in amperes (A). This value indicates the maximum output capability of the –12 V supply and helps users verify compatibility with power supplies or other components that require this voltage level.

The linear distance that a PCI Express power cable covers, expressed with a length unit such as meters, centimeters or inches. It represents the total usable length of the cable for connecting a power supply to a motherboard or other PCI Express device.

The total count of power connectors that use the PCI Express (6+2 pin) configuration on a device, such as a computer or power supply unit. This value indicates how many separate power connections are available for components that require PCIe power delivery.

The total count of Molex 4‑pin power connectors present on the product. This value indicates how many separate 4‑pin power contacts are available for connecting peripherals or components that require this connector type.

Indicates whether a power supply unit implements Power‑Factor Correction (PFC) technology, which improves electrical efficiency and reduces harmonic distortion. The value is typically "Active" for units that include active PFC circuitry or "Passive" for those without it.

The physical configuration or design of a power supply unit, such as ATX, TFX, SFX, or 1U. It indicates the dimensions and mounting options that determine compatibility with computer cases and other hardware.

The linear distance that a SATA power cable can cover, expressed in a standard unit of length such as millimetres (mm), centimetres (cm) or inches. It represents the total usable length of the cable for connecting a SATA power connector to a device.

A list of environmental, safety or quality certifications that a product has obtained from recognized authorities. Typical entries include RoHS, ENERGY STAR, CE, WEEE, TCO Certified, FCC, and other industry‑specific standards.
