Because 4 USB3.0 ports used simultaneously could draw a good bit of power the floppy power source idea is not a great idea for the long haul.

You can see from the link above that HP provides an adapter to pull power from a standard SATA power cable, but there are also 4-pin Molex to SATA adapters that can feed the card, and I even have driven the TI version of the card off of a floppy power feed-to-SATA adapter as an experiment. The NEC/Renasus card only provides 2 USB3 ports, and those are only on the backplane.ĭon't install drivers until the card is plugged in and the proper power is supplied to the card. I like the HP approach best because that ensures that with 4 total USB3 ports you can feed the TI based card enough power. Some other cards up- or down-regulate other slot voltages to 5V, but not these HP ones. Power: The two versions of the cards both need +5VDC power from the internal power supply. Read on for how you can use that internal header instead, by pluggin in an Akasa front case addition that results in two fully functional USB3 ports out front. Below is a picture of the card. note that the full kit from HP includes a little USB3 to USB2 adapter, which plugs into the card's internal header (square black plastic surround on the edge of the card that points towards the front of the case). the TI chip is on the motherboard now but same drivers work. That TI based card uses the same drivers as for the current Z workstations. You do want the later version of the card, based on a Texas Instruments controller with "2x2" output for 4 total two on the backplane and two internal. You don't want the first version of the card (based on NEC/Renasus controller), with only 2 total USB3.0 outputs, on the card's backplane. HP came out with two plug-in PCIe cards for those earlier Zs to provide USB3.0. The Z600/Z800 did not have USB3.0 built into the motherboard Z620, etc. Business PCs, Workstations and Point of Sale Systems.Printer Wireless, Networking & Internet.DesignJet, Large Format Printers & Digital Press.Printing Errors or Lights & Stuck Print Jobs.Notebook Hardware and Upgrade Questions.
