1. The link doesn't work

2. Ask such questions before you buy something :) 

Updated the link thanks and i actually thought i had a 550 watt psu but its only a 500 watt but on the r9 280 box it says minimum psu 500 the same as my 7790 box which i am running also on a 500 watt

If you're going to be running your pc for long periods of time you'll want to get a better psu to be safe, there is no fun in having a psu short and having it take out your motherboard and RAM. 

Well i just got the card delivered and on the box it says it needs 500 watts minimum.Also checked the card that i m running atm the 7790 direct CU II and that also sys it needs 500 watts? I will get a new psu after christmas anyway. Do you think the psu i have will do till after xmas.

The Information on the GPU box usually refers to system wattage. pcpartpicker actually calculates your estimated wattage in the top right of your build (274W in your case) it should be fine since there are no huge power hogs in your system.

500W corsair builder will be totaly fine

Ok thank you for your input.
