I am currently in the process of selecting parts for a gaming computer that I plan to build myself, and have selected the components I'm going to buy. I'm comfortable that I have found what I need, however I know very little about power supplies so I thought I would ask you guys. How powerful is enough? My build would include an Intel Core i-7 4770 CPU, a single (and later on, dual SLI-Config) Nvidia GTX 770, 8 gigs of Corsair Vegeance 1600 Mhz DDR3 RAM (maybe an additional 8 at a later point), a 2 tb 7200 RPM HD, an ASUS Z87 Pro motherboard (ATX), and an Asus internal 16X Blu-ray drive. This would be housed in a Corsair Carbide Series 300R mid-size tower case, which I am confident would fit the SLI dual-GPU setup, and as large a PSU as is necessary. When I add all the components into the calculator at thermaltake.com, with all components functioning at 100%, it says this setup will use 735 W of power. I know that it's good to have a PSU with a higher power rating then the sum of the power needs of each component added together, and good power efficiency as well. I don't want to skimp out in this department, neither do I want to have to pay more that I have to if possible. Originally, I was looking at the Corsair HX1050 1050 watt PSU (80+ Gold certified), however the Corsair AX1200i 1200 watt PSU (80+ Platinum certified) also caught my eye. Which would suit my needs better, or would something else entirely fit the bill better? I would simply go with the AX1200i, in the hopes that higher is better, however because there is a substantial price difference, and I don't now if the extra wattage would even make a difference, I figured I would ask you guys, who actually know, as this is my first build.
Thanks in advance! Sam.
PS. I would not be overclocking any components.
