So I just built a new rig, and I am having some problems with my PSU. I have an Asus Z87 Pro mb, an Intel i5 4670k, 12 gigs of Viper ram, a sapphire hd 7870 gpu, and a few different antec power supplies.
When I first set everything up, I was using an Antec 650 watt power supply with a 20+4 pin connector, and an 8 pin for my processor. I turned on my power supply, and I got led's to turn on on the motherboard, so I had power to the board. When I went to turn the system on, I got absolutely nothing from both the front power button, and the power button on the mb. After some troubleshooting, I got it to boot with a different PSU, using a 20 pin, and a 4 pin, however this was using a 380 watt, without my gpu in since the 380 can't handle my full system.
I have absolutely no idea why the mb wouldn't utilize the full 24 pins it has for the mb connector, or the full 8 for the processor. I have tried two different PSU's with 20+4 pin connectors but to no avail. I looked at the color coding on the connectors I've been using and the wire layout is different, could this be a factor? I'm thinking maybe the green wire isn't in the place it needs to be to tell the PSU to turn on. I'm willing to dump some money into a new PSU, but I would like to know what I need to buy before I get one, since there are some that my mb won't work with.
Thanks in advance!
