I recently decided to repurpose some parts for an emulation machine. I’ve taken my i5 4690k, and gigabyte z97N gaming 5 and paired it with solid gear flex mini itx psu. I get power to motherboard as the fan cooler gets going. That’s of course when I attached the 24 pin connection to the mobo. However of course the board still requires an 8 pin connection to the board.

the power supply only have the following cable attached to it. The 24 pin, a few connection for powering the hard drive sata connections, and a connection that looks like the PCI:E. Other than that there are molux connections Is there an adapter are there adapters out there? Because connecting the PCI:E connection ain’t doing powering up the board fully.

Ummmm .... there are single fan GPUs that can pull 300 watts. What model?

2664-front.small.jpg

R9 390 ... pulls 280 Watts (ish) at max.

Your motherboard and CPU are pulling 100-150 Watts ... that's not a ton of headroom for your GPU, assuming the PSU can really do 320 Watts.

What is the Watt rating on that PSU ... both the 320 and 220 I found include a 4 pin 12V connector.

*** Also ... what does "power up the board fully" mean? What comes on, what doesn't?

Its the 320 watt one. I didn't get a 4 pin 12V connector. The cpu powers up and the case. But that is about it. However I used my original PSU that has the 4/8 pin connector everything boots up like it does. So I am assuming its something with that cable. So I have the 4 pin connector (my bad) I see that. However if I plug that in I still get nothing. Do I need an adapter to connect the 4 pin to an 8 pin?

Per the manual for your motherboard (page 23), only a 4 pin is required (pins 3,4,7, & 8). With that plugged in all the way, the computer should start (I did say should). I'm assuming you have no GPU or other high power component.

There are adapters (1 2), but per the spec they are not required. **** perhaps I should say they "should" not be required.

No I’m using a gpu on the board. 320 W should be good enough to run a single fan gpu along with everything else. Right?

The 1650 ... per Anand you have idle power at 80 Watts ... max at 213 Watts ... that is full system.

Was double checking the power supply ... it does 17 amps on the 12 volt rail .. the 12 volt rail is used for most everything in the modern computer. 17 amp X 12 volts = 204 Watts. Per the specs, it should work, but you are butting right up against the limits.

This is for an emulator, so I assuming graphics are a non issue ... you have anything lower power?

no the only thing I have is 500 W evga 80 gold. And what’s funny is when I connect you t to that it works fine. But I can’t use it because it won’t fix in the case I’ll put everything in.
