Is cx450 enough to run 980ti

[AMD Newbie]

Hi. I want to buy 980ti and run it with my Ryzen 3 3100. I have Corsair CX450. Is it enough?

If you want to do some heavy undervolting then maybe

 

But honestly just get a better psu since it is a horrible idea to cheap out on a psu (from personal expericence)

I've been rold that cx450 is really good and should be enough

The TDP of a 980 Ti is around 250W, IIRC. That's well over half of your PSU's rated output. Also consider that it's generally not a good idea to have your computer's full-power demands right smack up against your PSU wattage. If you knock 10% off of your 450W, that takes it to 405W total, of which 250W are spoken for. You have 155W left over for your CPU, drives, mobo, etc.

 

Is that enough? Eh, if you have a 65W CPU and don't overclock it, probably. If you have a 95W or 105W CPU, absolutely not imo. I would personally just shell out for a 550W-650W PSU rather than chancing a 450W PSU on it. If it's a newer CX, it can probably handle it, but why take the risk? If it's an old green-labeled CX450 and you're going to push it that hard, just pour some gas on it to help it on its way.

My CPU is 65W Ryzen 3 3100. I've purchased CX450 in 2020. I need purchase 650m then?

The 2020 CX units are good. It's your call. I wouldn't run a 250W GPU on a 450W PSU long-term, but that's just me. I wouldn't expect your PSU to commit seppuku all over your PC from the components you have in there, but I wouldn't do much in the way of upgrading without a higher-rated PSU in there either.

The CX-M is only modular compared to the CX(non M). That's it. It's actually quite a downgrade

 

If you're going to upgrade, it's better to consider a better PSU (ex - TX550M for Corsair).

CX450 only has one 6+2 pin PCI-e connector and a 980 Ti needs more. Even 450w is enough for your system and CX450 is a decent unit, CX450 is not sufficient because of the connectors. @IIIIIIIIIIrecommanded a good one but if you let us know what your budget is and a link to a store where you want to purchase a PSU we can help you a lot better.

TX is high-end stuff i can't affrod. My budget is limited. I'm using 6 pin adapter. is it bad using one? hmm

Should i buy EVGA PSU then? I just prefer Corsair over any other brands

[--SID--]

What exact model EVGA?

 

You're using molex to 6 pin adapter? It's not recommanded. Molex connectors are not made for high 12v current.

Do you have a websitelink to the shop?

i don't have one.

Where do you buy the PSU, in a local store? What country?

in Russia. I think it's called DNS or something

Maybe @Juular He knows more about Russian stores than I.

So, should i get CX650 or BQ650? Is there any risks of using molex adapters?

[--SID--]

CX650 (not CX650M) is better than 650 BQ. CX650 has four two 6+2 pin connectors and you only need two. No need for dangerous molex adapters.

 

@AMD Newbie is Corsair CX550-F available?

is there a difference between 650m and 650M? I just saw one with just "m" and another with "M" I've been told that modular ones always better than not modular ones!

it is available. should i get one with F then? what is the difference? is it more special or something?

[--SID--]

What's the housing look like?

Is it

Or

Maybe @jonnyGURU can explain the difference except the housing?

[Middcore]

Not a great idea.

CX-F is a good budget unit. It's Bronze rated but actually it's near Gold but due to the RGB fan and competition  between Corsair models it's downgraded to Bronze. 550w is enough for your system. If the 650w is reasonably priced I'd take that one.
