Hi there

I recently upgraded my system due to some issues I was having.
Old spec:
i5 2500k
Asus rog gene v
8 gig ram
MSI gtx 1070 ti
AX750

I have changed it too:
Ryzen5 3600
Asus Strix B450-F
Corsair MP510
16gb ram
MSI 1070 ti
Same Corsair AX750

The issues I was having was with the usb's, they sometimes worked and randomly didnt and eventually the USB3 stopped working completely. Then sometimes when a USB would stop, the system wouldnt turn off.

Now the new system is fantastic however the other day, the same thing happened, usb stopped working and I couldnt turn the system off.

The old system was 8 years old apart from the GPU which is 2 years old. Assuming its not the GPU, the only other component I kept is the PSU. Does it sound likely that the PSU is starting to fail?
 
Thanks for your reply. When I got the AX750, I knew it was overkill but wanted the headroom for further upgrades. I really only upgrade the GPU over 7 or 8 years. is 550 enough or would I be better with a 650?
 
Would the Superflower Leadex 3 be a good replacement for the Corsair AX? I have built a couple of rigs with Superflower and they have been good but the AX was a premium model when I bought it. I was looking at the RMx series but looks like they are not made by Seasonic like the AX were.
 
I had a Super flower Leadex in one of my previous builds, brilliant unit, fully modular and 7 year guarantee...

The only thing I didn't like was the LED lights in each port but that's easily hidden if you have a PSU shroud, However I don't think all superflower PSU's have that feature

Thanks, I will have a look. Ive got a side window and led's would annoy me, i will check if they have them.
 
Leadex III doesn't have led's thank god!!

When you rebuilt the pc to the current configuration did you do a fresh install of windows? If not then you may have copied some problem over to the new build. USB failure would normally be down to the motherboard or a usb device compatibility problem and to have the same fault on a new build is strange.

Yep brand new install. I had windows installed on a Samsung SSD now it’s installed onto an m2 drive with the Samsung as a storage drive.
 
had a similar issue with my new build, but using an OLD gigabyte ODIN PSU, sent the previous motherboard back to the supplier as I thought it was the problem, but a new Gigabyte motherboard is giving me exactly the same issues.

Plugging in portable usb hard drives gives me drives connecting, then dropping, then connecting then dropping, or not connecting at all.
I noticed that the 5V rail was around 4.4 volts, and jumped around quite a bit, so I've ordered a replacement PSU which arrived today, am hoping that will sort out the issues.

Thanks for the post, would you mind updating me as soon as the new PSU is installed and had time to test?
 
Installed a seasonic prime 650 this evening snd it worked with both drives that had been clicking without issue. So psu was possibly failing.
