USB3 Upgrade For 3,1 2008 Mac Pro

[mtnhome]

My 4 HDD bays are full... WD & SG. 1 optical bay open.

What's the best way to get power connection to PCIe USB 3 card?

Is the Optical bay my only choice?

What kind of cable will I need?

Probably going with Anateck, Sonnet or Anker PCie card.

Seems their cables are meant for an open HDD Sata slot.

Do I have to worry about Power Supply issues?

Save for the 4 HDD's, an ATI 5770 VC and 14G Ram the Mac is a standard Quad.

Thanks!

It's all there, links to power extensions guides the lot. A 2 port you can get away with no power but if you use PCIe SSD cards or wish to in future you should have a cable run anyway. Mine in my 3,1 goes from lower ODD and splits three ways to my solo x2 with twin 840 evo's in slot 2 and the Inateck USB 3.0 card in slot 4.

The x2 hosting an SSD (two with thermal sticky pads in my case) frees my sleds up for spinning disks.
