20-pin PSU vs 24-pin Mobo Hookup?
My Chaintech VNF4 Mobo just arrived along with AMD 64 3000 CPU and 1G Corsair ValueSelect RAM. My PSU is ANTEC TruePower 480 with a 20-pin connector. The Mobo has a 24-pin connector.
Each connector has a "latch" connector device at the center on one side. Should the PSU 20-pin connector be inserted into the Mobo connector "centered" so that the latching connectors line up, with two open pins on each end of the Mobo connector? If the PSU connector should be aligned with one end of the Mobo connector leaving 4 mobo pins vacant on and end, how can I determine which ends to align and which pins should remain vacant? The POS manual with the Mobo only says to "Plug in the ATX power cable to the mainboard's power connector and make sure the cable is connected". Also, there is no mention in the Mobo manual of the 4pin black/yellow 12v connector, but there's a connector on the Mobo labeled PW3. As the connectors seem to fit am I to assume that this PSU connector should be plugged into PW3? Thanks for any help here. |

OK. I've found threads here and other forums with pictures and detail indicating how the connector should be inserted.
I've connected the PSU connectors, including the 4pin molex black/yellow connector for the CPU, to the Mobo as pictured in threads where the system was operating. RAM, CPU, and graphics card installed. Powered up... and nothing. No beeps. No CPU fan. No Mobo fan. I've tried attaching the case power leads for the front switch but it made no difference. I've removed and reinstalled the RAM, CPU, and graphics card. There's power going to the PSU, but when I power up nothing happens. Not even the PSU fan... How can I determine if it's the Mobo, CPU, or what so I can RMA? Thanks for any advise... |

Somehow,the board is getting no power,if it were the cpu,the board would still get power,even with no cards attached or memory,power would still go to board,if board was faulty,fans would probably get power.
The common link here is the power connection from PS to board is not set up correctly,a jumper is not set correctly,etc. Rereading your post,you say the psu fan doesn't come on either,do you have another power supply you could test with? I would look into the 20 pin to 24 pin adapter and see if that works, |
