I purchased a USB 3.0 PCI card that requires a 4 pin molex connector ( the card is male). When I plug in the molex connector (multiple female plugs) from the power supply the computer shorts or wont power up. The power supply is a 1000W Antex. Ther only auxiliary outlets are 6 pin. Can anyone help me?
check the voltage on the pins on the molex plug (coming from PSU)
red = 5v and yellow 12V
inner 2 wires are black (ground = 0v)
Is the 6 pin connector plugged into the correct socket on the PSU
I bought a AMD/Radeon GPU which has a PCIe 6 pin plug (female) which goes to a molex (male) plug
[for use if psu does not have a 6 pin PCIE (graphics ) plug]
All modern PSU's will have a number of spare molex plugs (femail) which are likely to be used on old ATA hard disks, optical disks or first generation SATA hard disks.
( so rarely used in modern PC's )
