5700XT consumes up to 220 watts. For very short periods of time (like milliseconds at a time), it peaks to 250 watts. 
The 9400F can consume up to around 100-110 watts in heavy CPU benchmarks, while gaming maybe a bit less. 
Everything else in your system (fans , mechanical hard drives if any, 12v rgb leds), add another 20-30 watts on 12v output. 

So you need a power supply that can supply at LEAST 250w + 100w + 50w = 400w on 12v output.   That's a minimum of 400w / 12v = 33.3A on 12v. 
Look on the label and see if your power supply can supply this much power on 12v. 
 
Keep in mind also that some models were only rated for continuous power at 30c ambient and if the temperature around the power supply goes over 30c you are supposed to derate the power supply by around 10-20%, making it a 360-400w power supply.
 
So will it work? Probably yes, because when you're gaming your CPU is not gonna be pegged at 100% so it's not gonna consume 100w. Same for the video card, it's not really gonna consume 220 watts all the time.  
BUT, your psu will run at close to 100% when you're gaming and that's not good, considering it's a budget psu where they cheaped out on lots of things...
 
Ideally though, you should aim for at least a 600-650w power supply, which can provide at least 500 watts on 12v output.

Country?
Prices of both gpus?
Usecase for gpu?
 
Id get the gigabyte since its a triple fan if its between these two cards
 
though id prefer a used 5700(xt) or 6600(xt) instead as those outperform a 1080 and are still around 120-160$

Is leaving the computer in this 'Never Sleep' mode bad for the computer? Will this be a problem when I download games?

What Kind of Case? Case airflow makes a big difference. 
Also did you just put this together or did you notice the temps a while after building?

What do you mean?
84 is fine temps, don’t worry unless it’s throttling.
if it’s like a lot of gpus it would be pretty quiet until it gets HOT (or In my gpus case, will cook itself and just turn off, seriously Amd, 95c shouldn’t be 50% fans), you can adjust the fan curves with MSI AB

I had a single fan on my rtx 2060 when I had it and only hit 75 tops. I feel that's a little hot. Unless his fan settings aren't optimal or there is no air flow in the case.

I never put mine to sleep. It stays on 99% of the time. I only have it set to turn off my displays after 30 minutes to prevent burn in. 

Not putting your computer to sleep isn't necessarily bad, however giving it a proper restart every now and then can help improve performance.

Hardware? Maybe, possible, not really. PC components tend to have a pretty good life span.
 
Windows on the other hand, probably would start to slow down and bugs could start to occur since Windows isn't designed with being on for prolonged periods of time.
 
I work on a Service Desk and I have come across PC's that have been running for 30 days + and basically cease to function because of memory leaks.
 
if you're planning on running a PC non stop i'd recommend using either Linux or Windows Server. 

The only directly comparable review on both is from tomshardware, which dont have the best detailed reviews, however they are comparable in performance.

rtings has the S3220 reviewed and it does well.

The biggest cons on both are less to do with the displays performance and more a reputation thing.
Dell is ...Dell. So customer support will be terrible.
and MSI's displays have an unfortunate reputation of having poor uniformity. This one 'seems' good however.
 
They are both VA mind you, so dont expect perfect motion handling. The S3220 does have the better contrast but both will be far superior to an IPS or TN display in that regard. The S3220 also does 'seem' to come with better out of the box calibration.
 
PURELY SUBJECTIVELY HERE ..... I actually had my father buy one of these to replace his old LCD display. I wouldnt have recommended it if i thought it bad, and from what i have seen of it in person, its good.
 

Hey,
So I’m looking to get an used pc for photo editing (Lightroom, Photoshop etc.)
 
Will this PC be good enough? 
 
i7 2600K 
H77 D3H 
8GB RAM 
Samsung Evo 250GB SSD
Seagate 300GB HDD
Sapphire RX 570 4GB 
Corsair Spec Alpha 
Thermaltake 550W
 
- 300$~330$
 
What do you think?

Just check out how much an am4 kit would cost for a Noctua D14? Its about 9€ here and you can ask for a free one from Noctua if you have proof of purchase for old cooler and new cpu&motherboard.
 
With those prices 212 is the best option of new coolers. 

Shouldn't happen on AMD GPU's (Prior to 5700 series) it should be a locked Coreclock.
Power limits aside of course....
 
 
 
OP - I wouldn't worry at all, some of the GPU's from AMD of that architecture didn't have the best power limits applied (AIB cards) and would drop clocks (few percent), but other models hold the clock ALL day everyday no drops.  (Card to Card differences)

I'd personally go with either the Eclipse P300A mesh or the NR600 ODD. The P300A I like because I personally believe Phanteks has some of the best build quality on the market for the price. However, if I was just going off which case I think looks the coolest I would say I really like the minimal design of the NR600. The Corsair option just looks cheaply built with that (in my opinion) ugly patterned plastic front panel, and I've never heard of the Antec option before so I can't comment on its quality.

You've just got it in in your head that 8 cores is better than 6. By all means get an FX 8100, I guess it won't matter because more cores is better, even though its 8 cores together are slower than an Athlon 3000G's 2 cores.
 
The Ryzen 5 3600 is faster even in terms of multi core performance. Its 6 cores are as fast or slightly faster than the 2700's 8. Not per core, altogether. 
 
 
 
 

no

that cpu doesnt need to be replaced. Id say get some more ram and a better gpu

Hello, 
 
I want to buy these sleeved cable extensions: 
 
https://www.ebay.com/itm/Sleeve-Extension-Power-Supply-Cable-24-pin-A-TX-8-pin-PCI-E-8pin-CPU-6-pin-4-Pin-/363087917091?_ul=IL&fbclid=IwAR284TrlPZkvbdL8NqXsgLYdxFZNaEXoG4FgOPaSwc_jiHqIdHpAFWH2sT0
 
Are they safe to use?

Wire got stuck in CPU fan, wasn't spinning. The CPU temperature was about 100-105C. 
 
Now it seems that everything is fine. 
Thank you!

Your broken cooler can most likely be fixed with zip ties.
But I'd like to see a picture of it.

I have an Arctic Alpine 12, personally unless budget required it (and yes they are affordable AF) I would go with something a little more robust than that due to the lack of airflow.  However if that is your only option it should work at stock settings.
