Question about USB 3.0 and USB C ports in front IO detecting devices, but no power detected.
Hi Everyone. I am new to this forum. I just finished my first pc build. I have a Fractal Torrent Case and a ROG Strix x670e-e Gaming Wifi motherboard.
On my case front IO, I have 2x USB 3.0 ports and 1x USB 3.1 Gen 2 Type-C port. Both are wired to the motherboards USB 3.2 Gen 1 header and USB 3.2 Gen 2x2 Type-C plugs, respectively.
The USB 3.0 ports on the front IO recognize devices when they are plugged in and appear to be "charging", however, I've tried to charge a keyboard in one of the ports and in 15-20 minutes it didn't charge the battery even 1%. I know these ports are not normally meant to charge, but I thought it would at least deliver some power? Do you know what maybe going on? I've checked my bios settings and all appear to be correct.
Lastly, I've tried to plug in my iPhone 15 (usb c) to the front IO USBc port and it says it doesn't recognize my device (which maybe because of my iphone settings), but I thought this port was suppose to at least charge faster, but I ran into the same situation where it says "charging", but in the 15 minutes it was plugged in I didn't even gain an extra %.
I'm just wondering if my USB ports are faulty or defective? Any advice or ideas on what maybe the issue. Thank you very much!
USB ports are okay. The issue lies in your expectations rather than the hardware itself.
USB 3.0 can provide up to 900mA at 5V, which equals about 4.5W.
Your device supports USB 3.2 Gen 2x2, capable of delivering up to 100W, but the USB type-C cable in your case is USB 3.1 Gen 2, rated for no more than 15W.
That said, your phone and computer likely won’t be able to charge themselves at those power levels; they require significantly more. For example, the iPhone 15 needs at least 20W to charge.
Here’s the truth: your hardware works, but your assumptions are incorrect.
By the way, I can charge my Samsung Galaxy A52S using the USB 3.0 port (4.5W), but it would take around 4 to 5 hours.
Instead, I use a wall charger that provides 15W and gets the job done in about 50 minutes.
Of course, I could purchase a faster charger (25W), but I haven’t done that.
