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?

Thank you for your response.
When I use the 6 pin Pci-e cord that has the multiple molex 4 pin female plugs the unit shorts out or won't power up. Could this be a voltage problem?

No, but there is a separate 6 pin to multiple 4 pin female molex cable that plugs in. This is the one that shorts out.

is this a modular Antec power supply ?

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 )
