If the PC now has the A8-5500 APU in it, that CPU will bottleneck the R9-280 somewhat. Not a deal breaker, but you won't get quite the full performance form the R9-280 due to CPU bottleneck. The R9-270/270X would be a better balanced gfx card for that CPU. Even the A10-5800K will struggle unless heavily overclocked.

The TR2 is one of the worse PSUs on the market. Rated in the last tier, the not recommended tier: https://community.newegg.com/eggxpert/computer_hardware/f/135081/t/45344.aspx?Redirected=true
This would be a better choice for that price: http://www.newegg.com/Product/Product.aspx?Item=N82E16817371044

The memory is fine, but are you adding it to some already in the system or using it alone? In a dual channel memory system, it is best to use matching sticks in like color slots. That's why dual channel memory is always sold in matched pairs.
And if you use a single stick, you won't be able to make use of the slightly faster Double Data Rate speed of the RAM. Maybe a 10% loss in performance.
