Hi,


Will a Antec 450 watt be enough for everyday gaming and this system: (?)
-CORSAIR VENGEANCE Low Profile 8GB - 2x 4GB DDR3-1600 CL9
-Gigabyte GA-Z77-D3H - Socket LGA1155 Z77 Express Chipset
-Gigabyte NVIDIA GeForce GTX 660 - GDDR5 PCI-E 3.0 Graphics Card
-Intel Boxed Core i5 3470 - 3.20GHz Quad Core

I am not into overclocking btw and will not overclock anything.

Thanks

For a system using a single GeForce GTX 660 (non-Ti) graphics card NVIDIA specifies a minimum of a 450 Watt or greater system power supply that has a maximum combined +12 Volt continuous current rating of 24 Amps or greater and that has at least one 6-pin PCI Express supplementary power connector.

Total Power Supply Wattage is NOT the crucial factor in power supply selection!!! Total Combined Continuous Power/Current Available on the +12V Rail(s) rated at 45°C - 50°C ambient temperature, is the critical factor.

Overclocking of the CPU and/or GPU(s) will require an additional increase to the maximum combined +12 Volt continuous current ratings, recommended above, to meet the...

Overclocking of the CPU and/or GPU(s) will require an additional increase to the maximum combined +12 Volt continuous current ratings, recommended above, to meet the increase in power required for the overclock. The additional amount required will depend on the magnitude of the overclock being attempted. Since you're not planning on overclocking then you don't have to worry about this.

The Antec Neo Eco 450, with its maximum combined +12 Volt continuous current rating of 34 Amps and with one 6-pin PCI Express supplementary power connectors, is more than sufficient to power your system configuration with a single GeForce GTX 660 (non-Ti) graphics card.
