Hi everyone, im going for a gpu upgrade. Will go from rx 580 8gb Sapphire Pulse to 6800xt Sapphire Nitro.

My question is, will the psu i currently have would be ok handling this system under gaming loads ?

You can see my specs,
Processor: 5600x AMD
Motherboard: B550 Msi Mag Bazooka
Cooling: Coolermaster Hyper evo 212 rgb
Memory: 2x 8gb 3600 mhz cl16 corsair ram.
Video Card(s): RX580 8gb >>> to 6800xt sapphire nitro
Storage: Samsung 500gb m2-nvme ssd
Display(s):
Case: Coolermaster TD500 mesh white
Audio Device(s):
Power Supply: Corsair CX650F RGB fully modular, bronze 80+ 650 watts.
 
You should be fine, I reckon. You have a max of around 500w load with spikes right now, and you are adding about 75w. You should have plenty of headroom to take care of the modern card's power spikes.
 
TPU recommends a 700W PSU for the 6800XT. Considering the high transient spikes modern cards have you might run into issues if the rest of your system draws a bit more power than usual (is your CPU overclocked for example?). You could try running with your current PSU and if you encounter random shutdowns during gaming you obviously need a new one. Reducing the cards power limit in Afterburner would make it usable until you get a better PSU.

Ty, if i experience any problems ill just limit my power limit, and get a new psu. What im scared of is, would the parts be damaged if my system shuts down ? Should i be worried ?
 
Nothing is going to blow up. Your PSU should shut everything off if it goes over the maximum wattage. Your card at most will pull like 300w.

I wouldn't risk a shiney new gpu with a cx/cs/vx/vs psu, that's bottom bin there, It would be like putting a Fram Oil Filter on a 2023 Z51 Corvette (big sin). Might get away with it on a 6700 (OEM) but 6700xt and up, nope.

I wouldn't bother attempting this, upgrade the psu to a Higher Grade Corsair, EVGA, SeaSonic, Antec, Superflower, Andyson.

Since you have the money to buy a 6800XT, you have the money to buy a PSU.

This makes a lot of sense. Additionally you can run the GPU with undervolting and then probably it will run flawlessly and on top improve the cards characteristics.
 
all i can say is that i ran my 3060ti for some time with a 500w PSU and running CP77 at 100%, all fine no problems at all. Recommendations are just that. Try it out, stress it, it's a quality PSU, if it works no point in spending more money unless you want to.

You can't fix dirty power by doing that.
 
overkill on psu is under rated ......good clean power and lots of it no substitute, bite the bullet get u seasonic and have that awesome power for a decade or more
 
i personally would not run a 6800XT off a 650W PSU.
it has transients that are more than 2/3 of the whole capacity of the PSU. it probably works but i would not trust it long term.

Especially on the corsair above, needs RM or better

Yes I agree if the PSU is up to spec. So many are cheaply made to the point where safeties are gone. Now this is a 650w Corsair Bronze. It won't blow up, but might not be able to handle the load.
 
The CX-F is pretty mediocre both build quality voltage regulation and ripple suppression are not all that great
Corsair is not the company that built it its a 3rd party OEM called HEC which is not known for the greatest quality

At full load the 12v rail is doing 1,81% which is pretty bad in this day and age and that means the system wont be as stable as it could be with better voltage regulation
5v and 3,3v rails are even worse

At full load the 12v rail has 48mv of ripple which is about twice as high as most other units
Its not all that great so up to you if you want to keep it or replace it

Just because it says Corsair on the box does not automatically mean its good
its not outright bad but its not good or high quality either
 
i have had this psu for almost 10 years across 3 builds

DId you know that the Seasonic X you have there is actually a multi rail PSU?
Everything you find online says its single rail but that turned out to be false it actually has four 12v rails

Someone over on the Jonnyguru forms found it out but since that site is dead and gone i cant find and show the post

Seasonic has done that before the old M12D was sold as a multi rail PSU despite being single rail
Anyway with GPU´s using more and more power you might start to have problems with OCP kicking in because you might overload one of the four 12v rails

I am not saying you should replace it i am just saying if you start to get shut downs with it you might just be overloading one of the 12v rails
 
its easy work around just use one 8 pin from each pci-e plug. ive always done that reguardless

I do for a 290 VaporX. I had every intention of getting another for Crossfire, or trade for a 290X VaporX 8G/390/390X Nitro.

I may jump in with RX 7000 or 8000.

1355W is max output on the unit

this is a good deal if u need a good psu i would however contact seasonic and buy brand new set of plugs for it life span is very large on these 70000-150000 hours

All PSU internally are Single Rail. The multi-rail is just marketing at this point. It makes no sense to limit the the output when its generated as a single-rail anyways. JonnyGuru has some good stuff on the subject if you can find his YT content.
