So I purchased a new Mobo, Asus Prime X670E Pro Wifi and AMD AM5 X7700 with 32Gb RAM and put this in my existing case which is an Antec 900 with the Corsair HX620W PSU. Ever since I built this the system has been fine but for initial start up the CPU and case fans come on, the mobo lights up but no beeps and just sits there. I press power button fort 10 seconds and it shuts down. Immediated press power button and system starts up fine. As the system components are so new and I'm running Windows 10 and BIOS in legacy mode, I thought it would be a patch update and would resolve itself. However, months on it still does it. I watched the below video on YouTube from a support channel and it points to the PSU v2.2 being the problem.

So, I'm looking to upgarde my PSU to resolve the issue. BTW I have done loads of unplugging and replacing other older cards so the PSU is the only thing it can be.

In addition to the above mobo, CPU and RAM, I also have 2 x 3Tb SATA HDD and M.2 NVMe and a Samsung Pro SATA SSD, and a Geforce 1080 Ti 11Gb.

So can someone recommend me a good PSU with ATX 2.3 that will likely last the next 10 years with my spec?

Thanks
 
Asus boards used to have an option in the BIOS, called something like: idle power control and it would address the incompatibility issue with older PSUs (at the cost of higher idle), you might want to check in the BIOS.

I wouldn't buy lower than 750, just to give you some headroom for a GPU upgrade in the future.

The GX-750 is an older design and doesn't have a 12/16 pin cable for the newer nvidia graphics cards, but it is still a decent PSU with a 10 year warranty.

The Corsair Shift needs a compatible case because of the unusual placement of the modular board on the side of the PSU.

The RM850e has a lesser fan and a 7 year warranty, but it is also a bit cheaper than the other PSUs for the same capacity.

The GX-750 looks a good well featured PSU. I'm just concerned its an old PSU and I'd like something that will see me into the next 10 years and as you say, I will be looking to upgrade my GPU in a year or so. So I'd like something like that but maybe a ATX 3.0 for power efficiency. I'm happy to go up to £200 for a good reliable PSU.
 
When you say professional, there are a bunch of pro reviews on all sorts of websites, including amazon, newegg................ok, not so professional. But I see OC website as my pro-reference site to go to. So is there a better PSU for around that prices for my spec?

This is the kind of review I look for:

www.techpowerup.com

Thermaltake Toughpower GF3 750 W Review - ATX v3.0 & PCIe 5.0 Ready

The Thermaltake GF3 with 750 W max power is an ATX v3.0 and PCIe 5.0 ready PSU, meaning that you won't need to use the dreadful 12+4 16-pin adapters since it has a native 12VHPWR cable, rated at 600 W. The PSU's performance is high, and it also has a quiet operation.

It is hard to say if the other PSUs are superior, because I don't know who makes the TUF PSU and what the innards are like.

Just taking it at face value, then it looks overpriced, because the SHIFT 850 is £135 and MSI's A850G PCIE5 is £130 (these are both ATX 3.0/PCIE5 PSUs with 10 year warranties).
 
So after doing some research into the PSU's I decided to purchase the below TUF Gamin 850W:

On Sunday, as a last resort I changed my USB panel for a new Akasa 3.1 v2 and 3.1 device. The problem still happened. I then applied some new updates from Armoury Crate and Updated to Win 10 22H2 and check BIOS for any PSU backward compatibility settings in Advanced settings, to which there were none. So saved BIOS and rebooted. Since then the problem has never happened. Every day I press power on and it boots correctly first tiime. So I guess I'm returning the PSU to save £151.

Not sure whats fixed it but I'm wondering if its a BIOS issue and just by going into Advanced settings and saving has kicked something back into life or was it the Armoury Crate chepset update. :)

So after 8 days of the issue not appearing, it started again yesterday morning. I've no idea whats causing this but I don't think its the power supply.

Did anything change after the 8 days? E.g. did you plug in, or install something that wasn't before?

Not sure why it could be the PSU, going off your first post.? But I have not used an older ATX PSU on a newer system before.

But, did you test the new PSU or did you send it back?

Could it be a POST issues, as it is not getting through POST, looking at the components plugged into the motherboard or the board itself as the potential problem.
I can't remember the POST sequence, you don't seem (?) to have a diagnostic POST code display on your board so could you try your internal GPU on your CPU and not have your GPU attached.
If that CPU has onboard graphics.

Removing everything unnecessary from the motherboard and test that for the initial boot.?

Corsair HX620W PSU

Now this is a right blast from the past, I can remember when this was the gold standard for PSU's and everyone was buying this.

That link redirects to a review of an HX1000i. FTR I owned a HX520 that I bought about 2008 I think? It lasted 3 years. To be fair Corsair replaced it with a HX650 & that failed too, But Corsair replaced that one but 3rd time was a charm so I sold it & bought a Seasonic, that failed. I didn't have a lot of luck with PSU's 10 years ago.

That's really weird because I read the review!

You clearly had some bad luck, but I do recall these models being the PSU du jour way back then.

Sorry its taken me so long to come back to you. So to answer your question, No, nothing. I switched on as I did every day and that morning the power came on, the system board lights up, the DVD/RW flashes as if its going through component pre-boot testing and the fans whirl away and then it just sits there, no beeps, nothing flashing on screen, nada! So I hold the power button down until it shuts down and the press it immediately, the lights come on and fans spin up as before then about 30 seconds in I here the fans slow down slightly and the screen comes on and the BIOS starts on screen.

I'm tempted to do a BIOS update as Armour Crate has a new BIOS update. I've not sent the new power supply back as I think maybe it is the PSU and its a tempramental PSU and voltage level thing.
 
So, I finally got around to installing the new asus-tuf-gaming-850w-80-plus and guess what? Still got the same problem.

I'm now totally stumped. The only other thing I've not tried is upgrading the BIOS. The new PSU is great though. Two things I have noticed is that on certain screen I did see a slight flicker in the screen, espacially on the home screen. Thats now gone. And I have noticed the response time to load apps seems to be more instant. Whether this is just my imagination but it does appear to be better. Oh and the cables are much more flexible to be able to ve moved and bound inside the case.

I'll look into the BIOS update and report back........
