Hi guys, I'm currently building a gaming PC and would like to know how many watt should my power supply have.

Here are my specs:-

CPU: Intel Core i5 3570k
Motherboard: Aus P8z77-V Pro
Memory: 8 GB DDR3 Ram
Storage: Samsung 830 Series 128 GB SSD & 1 TB 7200RPM HD
Video Card: MSI Gtx 670 Power Edition

I was thinking of buying a 600 Watt Power supply. Is it enough? and also what brand would you recommend me?

More about : watt

For a system using a single GeForce GTX 670 graphics card NVIDIA specifies a minimum of a 500 Watt or greater system power supply that has a maximum combined +12 Volt continuous current rating of 30 Amps or greater and that has at least two 6-pin PCI Express supplementary power connectors.

For a system using two reference clocked GeForce GTX 670 graphics cards in 2-way SLI mode NVIDIA specifies a minimum of a 700 Watt or greater system power supply that has a maximum combined +12 Volt continuous current rating of 45 Amps or greater and that has at least four 6-pin PCI Express supplementary power connectors.

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 most important 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 increase in power required for the overclock. The additional amount required will depend on the magnitude of the overclock being attempted.

Select from brands like Antec, Corsair, Enermax, PC Power & Cooling, Seasonic, XFX.

My budget is around US$ 110-120. But I may spend a little bit more if the product is really worth it.

The Seasonic M12II-520 Bronze (SS-520GM), with its maximum combined +12 Volt continuous current rating of 40 Amps and with one 6-pin and one (6+2)-pin PCI Express supplementary power connectors, is more than sufficient to power your system configuration with a single GeForce GTX 670 graphics card.

The Seasonic M12II-620 Bronze (SS-620GM), with its maximum combined +12 Volt continuous current rating of 48 Amps and with one 6-pin and one (6+2)-pin PCI Express supplementary power connectors, is more than sufficient to power your system configuration with a single GeForce GTX 670 graphics card.

The Seasonic M12II-650 Bronze (SS-650AM), with its maximum combined +12 Volt continuous current rating of 53 Amps and with four (6+2)-pin PCI Express supplementary power connectors, is more than sufficient to power your system configuration with a single GeForce GTX 670 graphics card. It is also sufficient to power your system configuration with two GeForce GTX 670 graphics cards in 2-way SLI mode.

Seasonic M12II 520 Bronze 520W for S$109.00
Seasonic M12II 620 Bronze 620W for S$125.00
Seasonic M12II 650 Bronze 650W for S$149.00
