Adoi, 3080 required min 700W PSU and in practical needs about 850-1000W due to 30series transient spike. Somemore CV550W unit is D tier, totally not Not NOT! suited for a high powered GPU in 3070-3080 segment. Ur lucky that puny 550W unit did not fry, or perhaps it did and took down ur GPU as well.

Even that RM750e is barely boleh pakai, your taking a chance there if still getting another 3080. Up it to a 850W A tier at least.

PS when you go high end your gotta make sure the other components can support it too

Trusting a brandname to be consistent is a real fallacy which most companies hope their customer to blindly rely on. This is why the PSU Tier List exist.

While Corsair higher end PSU are good quality stuff their basic & cheaper options are really just budget stuff with Corsair name tacked on. Your CV550 is a D tier rated unit only suited for igpu builds and you shoved a 3080 into it. LOL

Transient on 30series is a well documented issue and GN had done an indepth review on it


You can disgree but GN is a well trusted PC hardware reviewer and they present facts to back that up

A 3080 has transient that draws nearly the whole capacity of your 550W unit (which actually has a real capacity of 528W), what about the others like CPU, Mobo, RAM, fans & storage?


And this is what GN deduced from their investigation; the trip happen on the 12V which triggered OCP


Now see, good PSUs has good & complete protection. Cheap & budget PSUs typically lack full coverage and even if it stated to have OCP it may not be fully effective and overcurrent in the 12V rails could have passed on. Guess what, your GPU 8pin supply is directly connected to the PSU 12V rails.

This is the wattage unit GN reco to use. So its needed nearly 50% more than your 550W unit could handle!


Yes, you gotten a 750W A tier PSU but thats only AFTER shit happen isnt it? Its likely your GPU is ady killed before you upgrade to the 750W. And this is the bare minimum that GN recos you havent factored in if you will upgrade anything in the future or that PSU ages and thus its ability to handle "real" 750W will deteriorate with time. Mate, if you can afford a 750W A tier PSU, an 850W A tier unit isnt that much more costly.

Its between your words and GN. And far more in the internet community trust GN.

People come here should get the right info, not just listen to someone who claim others is nonsense or inaccurate without facts to counter but if people willing to go holland despite that then I can only say its on them and I feel sorry.

Didnt I told you your GPU is likely killed dy? Its in the last sentence in mine quoted that you replied back. Now maybe even your friend PC might have something due to it. Tuu lah dont be so stubborn when people give advice.

I long gave up your case dy. You want to continue killing hardware because what happening did not suit your understanding, then go ahead laa. I dunno what to say you anymore.

This is a good advice for those who think they know their right but its not
