Question Need New PSU?? Bad +5V Rail - Recommend

[MrN1ce9uy]

I've been experiencing (on and off) system restarts upon loading up a game or benchmark program. Yesterday, I noticed the +5V voltage was low as seen in the image linked below. Sometime later yesterday it returned to normal. I've had these system restarts occur at least one or two times (where it restarts multiple times a day for one or more days) in the past year. I believe it's time to replace the power supply.

If the PSU is the cause of this, I plan to RMA my current PSU, but if I were going to buy a new replacement and keep the RMA for a spare/backup/secondary system, please recommend a new PSU for the system below.

I'm looking for (up to five) recommendations across all brands. Buying in the USA.

check the Power with the PSUs tool:

Corsair Link ​

did you connect all ATX/EPS connectors?

Are you using any adapters between PSU and other devices?

check the front panel, disconnect the USB front panel and check the 5V

update the BIOS of the motherboard

I have not been able to find the connection on the motherboard for the Corsair Link data cable. I looked for it when I first got the motherboard and could not find it then, just looked again and do not see any connection for it.

I have all EPS connectors connected that the motherboard requires.

I am not using any PSU adapters.

Since the 5V is working now (4.905V currently) I have not disconnected the front panel.

I updated the motherboard BIOS yesterday. The voltage seems to be steady after doing so.

I guess I don't have to spend money after all.
