PSU: http://www.newegg.com/Product/Product.aspx?Item=N82E16817139049 GPU: http://www.newegg.com/Product/Product.aspx?Item=N82E16814125491 While looking over for the specs for the PSU, I noticed it only had 1 PCI-E power connector, while the graphics card takes two. Am I simply misreading this or do I need a different PSU?

  • The GPU requires 2 6+2 - pin connectors so the PSU wouldn't be able to support it. 430W also seems a bit on the low side but I have a tendency to go a bit overboard sometimes. What are the specs for the rest of your computer? – slow_excellence Jul 10 '14 at 21:10

  • I wouldn't go with anything below 620W in terms of power supplies if it were me. It gives a little bit of headroom for upgrades and overclocking if you feel inclined to do so. Newegg has a helpful Wattage Calculator that I like to use as a reference when building rigs. – slow_excellence Jul 10 '14 at 21:14
  • The build uses <400 watts, so 620W is tons of overhead. – Natecat Jul 10 '14 at 21:20
  • I made the mistake of assuming Dan was correct even though that number looked pretty fishy. It's been a long day for me :P . You also want about 30% overhead if my memory serves me correct so a 500W PSU should be more than sufficient. – slow_excellence Jul 10 '14 at 21:26

The R9 270 uses 150W of power. I don't know what other equipment you have in your computer, but it doesn't sound like you will have sufficient power. I recommend at least a 500W PSU for an otherwise standard PC build.

If you're not sure how much your computer consumes, try to virtually build the system on http://pcpartpicker.com (including all disks, fans, optical drives, CPU, RAM and everything else that consumes power). It will let you know if you have any problems with your build.

  • Does pcpartpicker check for availability of PSU connectors? pcpartpicker seems to not show any problems with my build. – Natecat Jul 10 '14 at 21:19
  • @Natecat check that by hand it's not hard everything required is in The specifications of the hardware – Ramhound Jul 10 '14 at 21:32

On the Gigabyte page they state that that GPU requires a 500W PSU with two 6-pin external power connectors. The PSU you link to is only 430W and only has one 6-pin external power connector.

Look for PSU with at least 500W and with two 6-pin external power connectors
