650W Power Supply

VisionTek's 650W power supply delivers the power needed to run your high performance machine.

With whisper quiet operation from its 135mm cooling fan, 15 device connections with heavy gauge wiring, and advanced circuit protection, the VisionTek 650W Power Supply offers the reliable performance your custom-built system deserves.


When Over-Current, Over-Voltage, or Short Circuit situations are encountered, the power supply will automatically shut itself off. The device will return to normal operation when the fault has been removed and the power switch is reset. Specific protections include:


Over-Current Protection
The power supply DC outputs are protected from supplying current above the maximum ratings and when output power is between 110%~150%. With the exception of the 5VSB output, all DC outputs are switched off in the event of an over-current on any of the DC outputs.

Over-Voltage Protection
The Over-Voltage sensing circuitry resides in packages that are separate from the regulator control circuitry. No single point fault is able to cause a sustained over-voltage condition on any outputs.


Short Circuit Protection
The DC outputs from this power supply are protected from damage due to faults. In the event of a short circuit on any output, all outputs will be disabled and remain so until the power supply is turned off and powered back on.


ATX 12V Compliance
Meets industry standards.


120mm Cooling Fan
Helps ensure highly efficient cooling performance.


20+4 and 4+4 CPU Connectors
Three Molex and four SATA connectors along with one FDD connector offer versatile installation options.


Advanced Circuit Protection
Automatically shuts off the power supply when overcurrent, overvoltage or short-circuit protection is triggered.
