5700 XT problem

Just as I suspected, if you take a look at the user reviews on that PSU you will
see the vast majority of people using one for anything more than a basic system
(no dedicated GPU or a very weak one) have problems.

3 things to be on the look out for when buying a PSU:

1. Does it have an 80+ rating (the PPS-650BR does not)
2. Always check reviews on whatever unit you are considering (there are none
for this PSU which is a very bad thing, it means it's so cheap and nasty no one
bothered)
3. Check user reviews to see what other users experience with the unit has been
like beyond the media review usage window.

If your selection fails at any one of those points pick another one to check out.

Looking at the specs on that PSU is even more telling, as I noted in one of my
previous posts about new old stock. The PSU has a hefty 5v rail and weak 12v rails
which means it was designed for old, pre Pentium 4 and older systems. It has 2
very weak 12v rails, neither of which is capable of powering the 5700.
For any system with anything past a budget discrete GPU you want a PSU with a
potent, single 12v rail, in your case at least 50A.

Take that PSU out and send it off for recycling, it's a cheap and nasty scam that
relies on end user ignorance and a low price to sell. The fact that adverts for
it list it's RoHS compliance as a selling point should tell you all you need to
know. One would hope complies with Restriction of Hazardous Substances. RoHS
has nothing at all to do with performance, build quality or reliability.

Sorry to be the bearer of bad news.

Good luck and let us know how you fare with the Nvidia GPU. It may be worth noting
that some older Nvidia workstation (Quadro) GPUs don't work on newer boards. It's
odd because their Geforce counterparts work fine just not the Quadro variants. If
your tester card isn't a Quadro it should work, if it is a Quadro then it not
working may not be as a result of the issue you are having. I hope that makes
sense.

No snotty remarks, people often list specs and leave the PSU out or are embarrassed
to admit they cheaped out on it, hence it being a valid assumption that a sub par
PSU could be at fault.

That link does not state the PSU's model, only a basic description. Active PFC is
promising that it may not be a dud but we need to know the make and model. I often
see off brand PSUs "rated" as much higher than they are. If your GPU isn't gettin
adequate power it could be failing to initialize or only partially initializing
which would fit with your description of the problem.

Another common issue with prebuilt PCs from unknown builders is a propensity to
use outdated PSUs that are not specced for modern hardware (higher 5v amps than
needed and not enough amps on the 12v rail).

Take a look at the PSU and see what make/model it is and let us know. I am about
70% certain it is where your problem lies.

Sorry if my post came off hostile, it was not intended to be. Posting on forums
is a far cry from conversing in person and things can all too easily be misunderstood.

Full system specs please.

Without knowing the rest of your components it's very difficult to figure out what
is going wrong. DDU was a solid suggestion but only rules out potential software
conflicts. If 2 separate GPUs have demonstrated the same issue then the problem
likely lies elsewhere in your system. I always suspect PSU first, particularly when
the PSU hasn't been listed by the person asking for help.

For sure... Windows will install the vga driver if you have an internet connection. Deconnect your system from internet before running DDU...
