VS450 450 W ATX power supply

The Corsair VS450 is a 450 W ATX12V v2.31 unit built for mainstream desktop builds. It delivers a single +12 V rail rated at 36 A and includes two 6+2-pin PCIe connectors, six SATA power plugs and a 24-pin main connector. The 120 mm thermally controlled sleeve-bearing fan adjusts speed with load. Active PFC and 80 PLUS White certification complete the package.

Sustained-load behaviour

Under continuous demand the single +12 V rail holds its 36 A rating without switching between multiple rails. The thermally controlled 120 mm fan ramps up gradually, keeping internal temperatures stable during long sessions. Active PFC maintains a clean draw across the 100-240 V input range, while 80 PLUS White efficiency reduces waste heat at typical loads. Over-voltage protection guards components if regulation drifts.

Deciding specification

The 450 W maximum output with a 36 A +12 V rail determines whether this unit can power your graphics card and CPU together. Add the TDP of your chosen GPU and CPU, then allow headroom for drives and fans; if the total stays below the 450 W ceiling the VS450 fits, otherwise a higher-wattage model is required.

Questions about this item

Will the 450 W output support a graphics card that needs two 6+2-pin PCIe connectors?

Yes, the unit provides two 6+2-pin PCIe connectors and a single +12 V rail rated at 36 A, which is sufficient for most mid-range cards.

Does the 125 mm length fit in a standard ATX case?

At 125 mm long it fits the vast majority of ATX chassis; measure your case clearance if the internal space is unusually tight.

What cables are permanently attached to this non-modular unit?

Fixed cables include a 24-pin ATX, one EPS12V/ATX12V, two PCIe 6+2-pin, six SATA and four peripheral connectors combining SATA, PATA and floppy.
