Can a PSU kill A GPU?

[newcbomb]

So just as the title says, can my PSU kill my GPU? Recently my GTX 780 died. My total system wattage was like 470W and i had an EVGA 500W 80+ so i though i was good cause 80+ but now i dont know. 

 

The question is, did my 500W PSU kill my GTX 780? Because ive already bought another 780 and im wondering if i should get a 725W or 650W

 

Thanks

Yes, a real bad one can. If you have a mediocre or decent psu, you’ll be fine. In your case, probably not

It shouldn't have, but it should also be noted that the 80+ is efficiency, and while it does have a small amount to do with quality, it is far from the end all in the matter. I'd buy a better PSU if you're worried about it, though you should be fine with that one. At least the 780 isn't a huge investment if it dies again

There's a PSU tier list kicking around somewhere on here. It'd be worth taking a look at.

You should get a better quality unit, not buy based on wattage.

 

An EVGA 550G3 or Corsair RM550x would be a good choice for a 780.

Why another 780 -

and yes it can kill your GPU - you should try to leave 100w or 15-20% headroom - atleast

Yes, it can. PSU can kill all your components (apart from something like the case, obviously)

 

80+ ratings don't indicate quality, just power efficiency. EVGA's W1 series (the 80+/white units) are pretty bad, so there is a chance that you had a power surge and your PSU didn't stop it. But it's not really a component killer just due to being close to its max wattage. 

 

Can't say whether the PSU is responsible though, there are many ways a GPU could die that are unrelated to the PSU.

The only way any PSU can kill a part is if it drives a higher voltage than what the part can take. So if it blew up and had a voltage spike during that time, then yes, it could have killed something.

Why not the 780? The Price/Performance is bonks. My Other 780 could match my friends 1060 3GB. Mine was $130 his was $225

Then your friends 1060 is bonks. And the power draw is a bit BONKS

Thanks everyone!

Nah, his gets a 8600 on passmark, mine got a 8500. That right there is bonks.

a 780 and 3gb 1060 do perform surprisingly close to each other.

ye, even an no brand psu with poor components inside made in china for cheapballing could have a 80+ rating yet catch on fire after a week and take all components with it lol

alright - but the powerdraw--- yikes

When you're not the one paying the power bill you tend to not care

An EVGA 500W has high ripple output at full load, and also bad voltage regulation in 12V-heavy situations, but as far as it's proven in reviews, it doesn't go out of the ATX spec. Did your PSU kill the 780? I'm sceptical about that.

[Guest]

Yes.  A failing or failed PSU can kill components.  That's why we tell you not to cheap out on your PSU.

 

And 80 PLUS is not a gauge of quality.  Only efficiency.
