Question

USB ports not working when too many hard disks are connected

Nov 30, 2017 9:14AM PST

OK, I already have this problem for several years now and I haven't found a solution yet.
My problem is the following:
I have a huge amount of stuff connected to the usb ports of my Acer Predator desktop pc, but sometimes suddenly a hard disk is no longer connected, or my usb mouse stopped working, seems to me that there is not enough power on the usb ports? All my external hard disks are powered externally too ... What can I do to fix this? Would a bigger power supply help? Which is now already 500W ? Hope someone can help me ..

I have :

Acer Predator G3-710
Specs: https://www.acer.com/ac/sv/SE/content/predator-model/DG.B1PEQ.026

And connected to the usb ports are several hard disks like Seagate & Western Digital 3TB & 4TB hard disks which are all powered too .. / usb mouse & keyboard.

Please help!

If these are USB powered drives

You may get into trouble. But small world the office just picked up a new Predator and with a single USB 3.0 2TB portable drive it seems fine.

I don't know what you meant by "all powered too" so keep writing. It would be clearer to share model numbers or write "USB powered HDD."

The obvious choice is to use one drive at a time for now.

Second idea.

I wonder if you are using the front ports. I find those to be lacking at times. Try to use the rear ports instead and to really fix it, install an USB 3.0 PCIe card.

Not USB powered

the hard disks are not usb powered .. they are plugged into electricity Happy All of them, could the problem be the power of the computer itself?

Unlikely.

I suspect the usual front port troubles. I see I mentioned to use the rear ports. After that I try other USB cables as these fail too often.

If the drives are suspect in any way, they are replaced. I've lost count of USB issues with USB HDDs that can't pass drive tests.
