USB3 PCIe card without extra power plug
I bought several of these cards, trying to find one that works with older
Centos linux. Most have a PATA Molex plug to import extra power. One has a floppy disk power plug instead! And one has no extra power. Now I believe PCIe x1 is good for 10 Watts. The powerless card only has 2 USB sockets, but if both were sucking in 900 mA, you would be cutting it fine. So would you only use 1 drive on such a card? Well, anyway the cheaper adapter cards slow down when you plug more than one device into them. The "superspeed" cards with PCIe x4 would be ideal, but they are more expensive to buy at random, hoping they will work..... |

Got those to work, although didn't run into and notice the PWR condition, at least for what I was looking at;- Mine worked straight PCI, neither smaller factored or the larger "graphics" -E slot. One of the boards I got has four USB slots, as I recall. Didn't do or put any extensive pwr-draw conditions, just basically verified they worked for higher USB3 speeds on USB3 pendrives. Set them up for Chinese written XP drivers for running USB3. Seems maybe W7 picked them up natively;- can't really recall now, other than it turned out more about testing than being comfortable with either card. One of them has the old VIA VL800 chipset. I thought an older model might be supported. It wouldn't even work in Windoze 7. I eventually found it works in opensuse Leap 15, so at least it didn't go to waste. |
