Solved Motherboard Fault B450 AORUS ELITE V2 (AM4) Rev 1.2?

My new PC is an upgrade of a gaming case. The items upgraded were Motherboard, CPU, and Ram. I had chosen this case as it provided lots of space for my Video collection which now extends to 4 conventional Hard drives, of varying capacities. I was not interested in gaming, so I thought the existing power supply would be sufficient, although , I was told on this forum, it was of poor quality.

CPU AMD Ryzen 5
MotherBoard B450 AORUS ELITE V2 (AM4) Rev 1.2
GPU NVIDIA GeForce GTX 750
RAM Corsair Vengeance LPX 16GB (2x8GB) DDR4 DRAM 3200MHz C16 Memory
PSU WIN Power AD-E500AE-A5/A6

The Motherboard has 6 SATA ports, though 2 were not available if an SSD drive of type m2 was installed. Neither of my SSD drives were of this type. I had also brought from my previous PC a PC Express card which supported an additional 4 SATA ports.

The upgrade seemed to go well after ironing out a problem in connecting the wiring of the front panel.

I had initially installed only two SSD drives, one of which was the system drive, the other used for data. However when I installed the DVD drive and three other of my drives only the DVD drive and one of the SATA Drives was recognized by Windows. I had been invited by Windows to upgrade to Windows 11, so I decided to do a trial, thinking it might help solve the drive recognition problem. It didn’t help and as I did not wish to tackle the complexities of the new system as well as the problems of SATA drive recognition, I have reverted to Win 10.

Reviewing the situation I felt that it might be a power supply problem, however the situation was not improved by reducing the number of SATA drives connected. The voltages reported in Bios and by Speccy seem regular

Another oddity was that the PCIe Card was initially recognized by Bios and flagged,during the boot sequence, with the i.d. of the drives attached, but this ceased after a while. In my previous PC the PCIe card and its drives was always flagged on boot.

I have discussed the situation with the sellers of the upgraded items. Their initial conclusion is that the motherboard is faulty. However if anyone can suggest an alternative solution before I dismantle the whole assembly I would be very grateful,

Thank you all for your contributions. The situation is now that my RMA request has been accepted. The tech help section of the seller said he thought it was probably a Mobo fault, so the Mobo is packed and wrapped for collection.

I have moved all the hard drives and the more powerful gpu back to my old case with its older mobo, and psu . All my SATA hard drives are recognised, including four attached to the PCIe expansion card, and the old case fits both the gaming GPU and the one PCIe card.

The psu in my Old case, is described as "ATX Switching Power Supply, Model: ATX500B". I attach a photo of the PSU Label in case it reveals more. It appears it is a generic unit, made in China and costing less than £20 new. I don't know how to get a full specs of a PSU. It seems it is comparable to the WIN Power unit in the new case.

I did try Win 11 before accepting the RMA, but it made no difference to the lack of SATA drive recognition. As its unfamiliarity was another hindrance I have now reverted to Win 10 pro.

I f the seller finds the Mobo is not faulty they will charge me for its return, however it is likely to be cheaper than any commercial service to test it fully.

I will advise outcome of Seller's RMA.

The seller states "Once your goods have been returned to Ebuyer, our usual turnaround time is 3-5 working days, however should your item be returned to the manufacturer for repair, please note this could take up to 28 days.

Collection by ebuyer is scheduled for next Thursday, May 11th. As my old PC is working adequately with the upgraded video card helping, I'm not too concerned about timing.

Yes, it was picked up yesterday. Don't expect a response before mid week. If they say its not faulty, any ideas about what questions should I ask them about their tests?

If the result is that i have to accept it as is, at least for now, I would be inclined to go for a new power supply. The only part of the system I have not upgraded. Indications are that 500W would be more than adequate for my setup, if the unit really makes that rating. I have seen disparaging comments on the Chinese "500 W" units not in fact deserving that rating, but don't know how I can test that.

Excuse my failure to reply to your last quesries.
The situation now is that the Motherboard was returned by sellers, after testing, with no fault found.

I have concluded from this the fault probably lies in the PSU. This is perhaps supported by the old case and its PSU now running satisfactorily with 5 out of seven hard drives recognised fully. This PSU has marginally better specs than that in the new case.

I have now purchased a used PSU, namely the EVGA 600W Bronze unit. Represented as in perfect working order. From its specs I can see the actual power available is much above that of my existing units.



At this stage the pressures of gardening have taken over my life. I will return to the upgrade when time permits.

Thanks to all contributores for their help.
