A failing power supply causes random shutdowns, restarts under load or a PC that will not start at all. If you are not sure that is the fault, we can test yours before you replace it.

Choosing a power supply
Wattage
Add up what your parts need and leave some headroom. The wattage your graphics card's maker recommends is a good guide.
Connectors
Check the unit has the leads your graphics card needs: 8-pin leads for most cards, or the 16-pin 12V-2x6 connector on the newest.
Never mix modular cables
Cables from a different power supply can look the same but be wired differently. Using them can destroy drives and other parts, so only use the cables that come with the unit.
Efficiency
The 80 Plus rating, from Bronze to Titanium, shows how little power is lost as heat. Higher ratings usually run cooler and quieter.
