Uhh... Is 650w enough for a 4080?!

Lol. It's working sooo... Yeah? And the connector isn't even melting!

4080 is surprisingly efficient compared to the 4090. She only has an i5 so there was some overhead.

Huh. At least it should shut off if it overloads... Good power supply. I overloaded one before that was a thing. Took a few other things with it.

I mean it will work. But GPUs can tend to have power spikes. When it spikes, it will throttle itself, so may experience performance issues. I think I may have a 750 PSU laying around that I used when I originally built my PC.

My 7900XTX requires an 800w PSU, but I've been doing perfectly fine with a 750w. And thus far, I haven't had any issues with transient spikes. Granted, I'm also running a 5600x so it's not like I'm drawing a lot of power.

Correct, in a way, your 7900XTX doesn't draw its full power or cores, mostly because of a 5600X bottleneck, minimal, but there is one. If you were to switch, in an extreme case, to a 58 or 5900 and were using a rendering software, or playing at 4K ultra, so will see the power spikes and thus the performance issues.



Not saying that it is wrong to have it a PSU rated less than the recommended specs by the manufacturer, because the power spikes are purely circumstantial driven.



Think about it as putting 87 gas on the twins.

The problem running a power supply hot is its not very efficient and heats up it up... So the risk is a PS component failure which cascades.

I believe even the weird transient power spikes some cards exhibit would just lead to stutter or other glitches or a shutdown in the power supply, given insufficient headroom in the PS. Those would be relatively safe.

Case in point:
Sort of related. The north shore on Oahu gets kinda shitty power.
So much so that I used to tell my customers to get a UPS as a load manager because PSU's were dying from brownouts. Not enough to have a full on reset of anything but enough to make the lights dim.

Yeah, I got the same advice in Pennsylvania. Now I always run a PC off a UPS. The problem is that UPS units get expensive after a certain capacity (moreso than pc power supplies) and you have to replace them/batteries periodically. Now that power draw is getting higher, I might change my perspective on this lol.

Yep, that why I just told them something to help with the brownouts not so much for something long lasting if there was a straight outage.

Spent Saturday working on my son's Alienware gaming desktop (Aurora with Ryzen 7, NVidia RTX3060)

He has had problems off and on with it over the past few months with sluggish behavior (like boot of times to desktop of as much as 15 minutes, and game loading taking as much as half hour). His warranty had just expired so I convinced him to let me take a look at it.

Basically, it was disk bound, with the disk running at 100%, not an unusual problem for Windows 10 and 11. I tried all the normal tricks, stopping unneeded services, changing the memory cache, disabling some IDE functions, etc. Only moderate improvement.

Swapped out his spinning 1TB drive with 2TB SSD (thank you Clonezilla for making that easy), more improvement but not the best. Also switched it from SCSI Raid to AHCI (he only has one drive).

Finally, did a WIndows refresh using the USB/Retain you Apps method (basically a Windows version upgrade without actually doing version upgrade). That led to huge improvement. Power off to running a Steam game (I used Gunfire Reborn as benchmark) is under 45 seconds, including logging in and selecting the game manually.

Obviously, there was something massively wrong in the Windows install, although not sure what.

Convinced my mother to upgrade to a newer computer. It was getting extremely sluggish and after running malwarebytes I discovered 420 issues! After I got the computer cleaned up it ran slightly better. Well this poor Gateway from 2013 was at it's end. I cracked it open and it only had 8gb of RAM (dual channel however!) and an AMD A6 APU.



While overkill, I convinced her to get one of the Minisforum Venus UM790 computers. It was small, extremely powerful by her standards, and with 32GB of RAM, and a Ryzen 9 7940HS, it should last another 10 years just fine.



In other news, the laptop experiment is going really well. I've adjusted to the small screen and now I'm moving into the more rigorous testing of games. Namely Metro Exodus and Dirt Rally 2.0.

So this may be happening to mine....

As you saw before, I'm running the 7900XTX with a 5600x. Well my H1v2 has a Gold rated 750w PSU and after even a mild gaming session with Dirt Rally 2, Metro Exodus, Dead Space (2023), and a few other games, that sucker is screaming. At first I thought it was my AIO or even the graphics card since my previous 3070 was pretty loud, too. But nah, it's the PSU and it hums pretty loud for a while before simmering down.



I have two choices: I can upgrade the PSU, which involves some work but is doable. Or I downgrade my GPU. I'm currently leaning towards the latter.



So if anyone wants an MSI 7900XTX...

Even though I would be pretty interested in your GPU. Have you tried under-volting it?

really your best option would be to upgrade the PSU, I forget you have a SF case so I can imagine the pain that would be to rewire everything.

My 6900XT requires at minimum 700W PSU, BTW.
