Depends on it's rating. For example, an 80+ platinum could run that at 450W easily. Depends on energy efficiency.
I don't understand why the efficiency matters. A PSU's rating means that it's guaranteed to supply that wattage regardless of how efficiently it does it. --- 4670k | 2GB GTX 770 OC | 8GB 1600 9-9-9-24 | 120GB SSD | 1TB WD Blue | Win8.1 Pro http://i597.photobucket.com/albums/tt56/S26DG44B/PsythikViolet_Blooded.jpg

The reviews for PC Power and Cooling (Silencer Mk III series iirc) were positive as well, and they (at least used to be) cheap for modular PSUs. --- Brought to you by GameFlux Free GameFAQs app on Google Play!

There's some kinda iffy info in here. As someone mentioned, efficiency should be irrelevant when it comes to what a PSU supplies. A 500W PSU should supply 500W if it's 80% or 90% efficient; the difference is how much it draws from the wall.
Also, many PSU "brands" aren't real brands. Companies like Corsair don't actually manufacture anything, they just relabel units made by companies like FSP or Seasonic. So it's best to look up professional reviews from a place like johnnyguru since quality will be unit dependent. Though I guess you can generalize if you know that a "brand" is always made by a specific manufacturer.
And as for how much wattage you need, it depends on if you'll do overclocking. One way of getting an idea though is to look up professional reviews for the card as they'll have a section about power consumption (you'll want to look at total system under full load). Some reviews will actually have power stats for when the card is overclocked (CPU is almost always OCed by default in reviews). --- http://i.imgur.com/ULj4q.jpg Let strength be granted, so the world might be mended.
