I have the following components:
Asus F1A75-V Pro Motherboard
AMD A8 3870 APU
Kingston HyperX Ram 16GB- KHX1600C9D3K4/16GX
and an OLDER power supply: Thermaltake TR2-430W (W0070RU) - which was working on an older build until I took it out 2 hours ago and dropped it in my new case.
I (foolishly) installed everything in my case, and connected a brand new Corsair SSD (Force3), and connected in all the stuff (USB2 ports, audio in/out, power and reset switches and LEDs). With everything connected I plugged in the power supply and flipped the switch on the PSU. The Standby Light on the Motherboard came on. I pressed power button on the front of the case, but nothing happened (nothing changed that I could discern, no noises, no fans, no additional lights, no flicker in the standby light, nothing...) .
I have since disconnected everything, and pulled out all but one stick of ram (I've rotated which stick, and which slot I'm using), but I still get the exact same results. The Standby light on the MOBO turns on, but nothing else happens when I hit the power (or reset) buttons. I've also tried unplugging the leads to the power switch and manually bridging the gap with a screwdriver, but with no different results.
All that is connected now is: APU is on motherboard, with provided heat-sink/fan installed and plugged in.
One 4-gig stick of ram
The Power supply 24-pin connector is plugged in securely, the 4-pin 12V connector is plugged into the rightmost half of the 8-pin plug on the board (the only way in which it will physically go in, and also the only way it would cover the pin labelled "Pin 1" on the motherboard).
OK- so probably way too much info, but here are my theories, hopefully you can invalidate them or provide others.
1. The quad core APU can't run on only a 4-pin power supply- if so, would a simple 4 to 8 pin converter fix my problem?
2. The ram is incompatible with the board (this exact set isn't listed as being compatible, but the 12-gig set with essentially the same number is on the list: ASUSTeK Computer Inc. -Support- Memory/Device Support (F1A75-V PRO) F1A75-V PRO
3. The Motherboard is DOA.
Am I missing something obvious? Is there anyway to test the above without buying anything additional? Is there another problem that I could be having? Any thoughts are appreciated!
