I'm thinking of having a new custom gaming PC built. I have some specs in mind, but I'm not entirely sure if all the components I've selected will be adequate to function together, mainly the power supply and the motherboard. I'm not sure what to look for in either of those components. Below is what I'm considering.
Windows 7 Home Premium x64
Intel i5-3570k quad-core processor @ 3.4 GHz
AMD Radeon R7-260X 2 GB video card
8 GB DDR3 RAM
1 TB Western Digital Black HDD
EVGA 100-W1-500-KR 500W ATX12V PSU
ASRock B75M-GL R2.0 LGA 1155 Intel B75 motherboard
If I could get any advice on this, I'd greatly appreciate it.
