Where to obtain power for USB 3.0. PCIE card?

Hello,

I have a DELL Studio XPS machine. I want to install a USB 3.0 4 port PCIE card.

Have any DELL Studio XPS users added an USB 3.0. PCIE card? Where did you find the power for it.

Thanks

Stu

What make and model is the card? Most draw power from the power supply using a 15-pin SATA power cable adapter.

Something like this: Newegg.com - COOLMAX 6" Cable Model SATA POWER ADAPTER - Cables

The ones I've seen use a MOLEX connector. Just find a spare one coming from your power supply.

Have you got any specs for the card? the one I used to use did not need an external power supply.

Yeah, they come in two flavors Pooch. Some manufacturers add the 12v booster so as to provide "proper power" to multiple USB connected devices. But others do not, drawing power right off the PCI bus.

I'm sure it has something to do with the number of ports. A 4 port card would definitely benefit from the extra power.

Additional information

Greetings,

Thanks to all that replied. The card that I am interested in is

Newegg.com - GWC USB 3.0 4-Port PCI Express Card Model PU3040

On the card it has a male molex connection. My Old DELL had at least one spare female molex connections in it.

My current Dell, has a free connector , but it is not the usually white molex connector. It is a smaller female connector. I have included a couple a pictures of the connector.

This is why I was looking for owners of a DEll studio XPS 8100 machine, who had expeirence with supplying power to a pcei card.

I am not sure that this connector is for power

Thanks

Stu

The connector you show is a dedicated Floppy Disk Drive connector. It does supply power.

Are you saying that the floppy drive connector is the ONLY free connector you have coming from your power supply? That would be unusual.

If you don't have a spare molex connector you will need one of these.

Newegg.com - Athena Power 8" Molex Y Splitted Power Cable Model CABLE-YPHD

There are cards available that do not require the molex connection but they will prpbably have less ports.

It might be the time for a new power supply. Filling out the rest of your specs would help us.
