How much wattage does my power supply need?

I'm building a Gaming PC in a few days, and I'll be purchasing the parts soon. Here are my specs:
CPU: Intel Core i5-4670K
CPU COOLER: Cooler Master Hyper 212 EVO
MOTHERBOARD: MSI Z87-G45 Gaming
RAM: Corsair Vengeance Pro 8GB (2 x 4GB) DDR3-1600
SSD: Samsung 840 Series 120GB
HDD: Western Digital Caviar Blue 1TB 3.5" 7200RPM
GRAPHIC CARD: Gigabyte GeForce GTX 760 2GB
DVD DRIVE: Asus DRW-24B1ST/BLK/B/AS DVD/CD Writer
CASE: NZXT Phantom 410

The total consumption of those parts (including my monitor too) uses around 400 watts. But, my graphic card recommends a 500W PSU. I was considering purchasing a 600W PSU though, but I'm wondering if that's enough? Because I'm also considering this 750W PSU that's basically the same price: http://www.canadacomputers.com/product_info.php?cPath=3...

Anyways, can you tell me how much wattage I should have? The minimum and maximum wattage I should consider? Thanks! :D

A quality 550W for the build you have currently but about 750W if you plan to SLI. In case you forgot, your monitor has its own power source.

So either a XFX 550W or Corsair TX750 V2.

Here is Guru3D's power supply recommendation:

GeForce GTX 770 - On your average system the card requires you to have a 550 Watt power supply unit.
GeForce GTX 770 2-way SLI - On your average system the cards require you to have a 750 Watt power supply unit as minimum.
GeForce GTX 770 3-way SLI - On your average system the cards require you to have a 1000 Watt power supply unit as minimum.

If you are going to overclock your GPU or processor, then we do recommend you purchase something with some more stamina.


TX750 will work if not OC'ing....if ya are, Id use an HX850

Wait but I'm not using the GTX 770, I said GTX 760. Oh and are you sure why won't the TX750W be enough? Isn't 750 more than enough even when over clocking?

For a system using a single GeForce GTX 760 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 GeForce GTX 760 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 50 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) may 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.

The Corsair Enthusiast Series TX750 V2 (CMPSU-750TXV2), with its maximum combined +12 Volt continuous current rating of 62 Amps and with four (6+2)-pin PCI Express supplementary power connectors, is way more than sufficient to power your system configuration with a single GeForce GTX 760 graphics card. It is also more than sufficient to power your system configuration with two GeForce GTX 760 graphics cards in 2-way SLI mode.

THANK YOU SO MUCH!!! You made everything seem so easier! Thank You!
