New build...Won't turn on

Hi guys,

So I just built a new computer and for some reason the thing won't turn on. I took the power supply in, and the tech tested it and it worked, so that shouldn't be the issue.

Here are my components:
- Kingston HyperX Fury Memory Black 16GB 2X8GB DDR3-1600 CL10 Dual Channel Memory Kit
- Corsair CX Series CX430 430W ATX 12V 80 Plus Bronze Power Supply 120mm Fan
- Seagate Barracuda 1TB 7200RPM 64MB SATA 6Gbps 3.5IN Internal Hard Drive - OEM
- ASUS Xonar DG 5.1 Channels PCI Interface...
