What wattage should I be looking for in a power supply for my PC build?

I'm currently ready to purchase parts to build a new gaming PC and sadly, in the past, I've always had to ask for assistance with choosing a PSU/Power Supply. I want to go with Corsair for the brand as I hear really good things about them. I just cannot, for the life of me, figure out what wattage I need!

Also, I do not plan on overclocking at all and if there are tips, formulas or references that may help me with this issue in the future they would be greatly appreciated. My current combine carts from Newegg/Tigerdirect are as listed below.

Thank you in advance for your time and consideration!


CPU - Intel i5 3570k
MoBo - Asus P8Z77-V LX
GPU - EVGA GTX 680 4 Gigabyte - Non OC'd
RAM - 4 x 4 Gigabyte (16gb) 1600 mhz
SSD - 60gb Intel SSD
HDD - 2tb Seagate SSD
Cooling - Corsair H70 (Is actually on sale for less than the H60)



Answer
Your system is going to require about 600W of power. IF you plan to expand such as adding an additional GFX card you should account for an additional 150 - 200 watts. I would recommend around 850W to account for potential upgrades.

Things to consider are 800 - 900 watts of power. Number of SATA connectors and PCIe connectors. Modular PSU are better for cable management but not necessary. Efficiency is also important.

A test in 2005 revealed computer power supplies are generally about 70â80% efficient. For a 75% efficient power supply to produce 75 W of DC output it would require 100 W of AC input and dissipate the remaining 25 W in heat. Higher-quality power supplies can be over 80% efficient; energy efficient PSU's waste less energy in heat, and requires less airflow to cool, and as a result will be quieter.

Various initiatives are underway to improve the efficiency of computer power supplies. Climate savers computing initiative promotes energy saving and reduction of greenhouse gas emissions by encouraging development and use of more efficient power supplies. 80 PLUS certifies power supplies that meet certain efficiency criteria, and encourages their use via financial incentives. Efficient power supplies also save money by wasting less power; as a result they use less electricity to power the same computer, and they emit less waste heat which results significant energy savings on central air conditioning in the summer. The gains of using an efficient power supply are more substantial in computers that use a lot of power.

Look for PSU with an efficiency rating of 80 PLUS GOLD or 80 PLUS PLATINUM. 80 PLUS SILVER is just as good but GOLD and PLATINUM is better. 850W would be your best bet, but if you do not plan to upgrade for a few years a 650W PSU will be fine for your build.

Hope this helps and GL.
