Windforce 770 4GB Power Requirement

Hardware GPU

I'm getting a GTX 770 soon and I decided to go with the Gigabyte Windforce GTX 770 4GB. I was wondering if my PSU could handle it.

That is my current PSU and I'm a little worried it will be too weak to handle the card.

More than adequate. You could pass it off with a 450 watt PSU.

Should be fine. I don't think 600w is even necessary, despite what the spec says.

More then enough. even a decent 500W can handle a single GTX780  no problem ☺
