This is not my first time inside the guts of a computer, but it is the first time I've built one from parts.

The PSU is connected in all the appropriate ways, the CPU seems well seated (is there supposed to be THAT much resistance when securing that metal housing?) the CPU fan is seated with fresh thermal compound, there is an 8 gig stick of Kingston 1600 RAM in the DIMM_A1 slot and an LED TV connected via HDMI directly to the rear port. When I turn on the mobo via the Direct Key switch the fan on the CPU starts and the board appears to be powered. This is where the show stops, and the CPU_LED light is solid red. On the first installation it powered all of the case fans as well.

Full specs:
CORSAIR HX Series HX850 850W
ASUS GTX770-DC2OC-2GD5 GeForce GTX 770
LG Black 14X BD-R 2X BD-RE 16X DVD+R
Intel Core i7-4770K Haswell 3.5GHz LGA 1150
Western Digital WD Black WD1002FAEX 1TB 7200 RPM
ASUS SABERTOOTH Z87 LGA 1150 Intel Z87 HDMI SATA 6Gb/s USB 3.0 ATX Intel Motherboard
Kingston HyperX 16GB (2 x 8GB) 240-Pin DDR3 SDRAM
Antec Twelve Hundred V3 Black Steel ATX Full Tower

New information:
I have been breadboarding it on the mobo box, there was no speaker sent with the motherboard to hear beeps. I have no way of testing the PSU (yet)
 
Solution
If the CPU fan is spinning when starting the board and still red CPU led, then it's either a board or a CPU issue. Most probably the motherboard.

I have been doing that, after reading the sticky on boot issues. Still red light, and I am using the stock fan.

I have that same motherboard and gpu, have almost connected them however I am unsure if I have enough power connectors for the gpu. Is it ok to leave 6 power connectors free or should they all be used?

Cheers
