  1. 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
  2. hec HP585D RETAIL 585W ATX12V Power Supply...I just bought it new from NewEgg.
  3. 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.
  4. 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 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 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
  6. Thank you so much...I will try it and let you know.
  7. No problem, anxious to see if it works well for you
  8. 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?
  9. 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
  10. Thanks for your help...I assembled it...I turned it on...and now I am seeing that my KB is not started another thread ([New System Build] Finished building my first computer...Keyboard not working ). Thanks
  11. Have you enable USB connectivity in the BIOS? try a PS/2 keyboard and see if that works
  12. Tried PS/2 keyboard actually...I don't have a USB KB.
  13. 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
