Power connector mismatch PSU & MoBo

[dm2010]

Hello,
I got 1 2X10 power connector and 2 2X2 power connector from the PSU. My MoBo (Gigabyte GA-MA785GM-US2H) needs 1 2X12 power connector & 1 2X4 power connector. What to do?
Thanks

Whats your PSU?
You can get a 2x10 to 2x12 adapter for a few dollars... and also a 2x2 to 2x4 adapter for cheap as well.
Seems like your PSU is ancient.. i would recommend upgrading that

hec HP585D RETAIL 585W ATX12V Power Supply...I just bought it new from NewEgg.

Ah ok, judging by the pics of it, the 20+4 connector thats together, use that to plug into the HDD cage end of the mobo.. also theres a 4 pin CPU connector, plug that into the socket by the CPU socket.

I am new in this computer assembling thing...this is the first PC I am building....So could you please let me know if I can do one of the followings?

1) plug the 1 2X10 connector from PSU to 2X12 slot of the Mobo....plug 1 2X2 into the rest of the 2X12 slot...plug the other 2X2 connector from the PSU into that 2X4 slot of the Mobo...in this case in that 2X4 slot of Mobo, 1 2X2 slot will remain unplugged.

2) plug the 1 2X10 connector from PSU to 2X12 slot of the Mobo....plug 2 2X2 connectors into the 2X4 slot of the Mobo...in this case one 2X2 slot of the 2X12 slot will remain unplugged.

thanks for your help

Option 1 is the proper way to do it.. 2x4 for the CPU isnt fully required, it just gives more power to the CPU, for higher wattage CPUs or OCed ones

 

[dm2010]

Thank you so much...I will try it and let you know.

No problem, anxious to see if it works well for you

Can I ask you another question? As a next step (in the Mobo manual), it says connect North Bridge fan cable to the North Bridge Fan header. I don't see any NB_fan cable. Is it alright?

 

[p1n3apqlexpr3ss]

Im guessing it means connecting the HSF 3/4pin cable to the fan header on the mobo.
You see the cable coming from the heatsink and fan? make sure its plugged into a 3/4pin header labelled CPU_FAN or something similar

Thanks for your help...I assembled it...I turned it on...and now I am seeing that my KB is not working...so started another thread ([New System Build] Finished building my first computer...Keyboard not working ). Thanks

Have you enable USB connectivity in the BIOS? try a PS/2 keyboard and see if that works

 

[dm2010]

Tried PS/2 keyboard actually...I don't have a USB KB.

 

[p1n3apqlexpr3ss]

Oh right, go into the BIOS and make sure PS/2 support is enabled, it wouldnt suprise me if its automatically disabled at stock for whatever reason
