Power consumption increase in upgrade

[Bloody Spy]

Hey, so i sold my old system and got a couple bucks to make an upgrade.

I got across a very good deal on a "defective" (pretty infamous) reference GTX 480 but i dont know if my psu can handle all that Fermi power.

 

Phenom II X6 at 1.34V

2x2GB 1600MHz Ram

450W PSU

If it can handle the power consumption that would be a pretty significant upgrade for me. Can yall give me some light, i came across reviews that point out its just enough at peak. Thanks.

Don't actually since that calculator is awful and has monetary incentive to exaggerate how much power your system will demand.

I would not pair a 450W PSU with a GTX 480. I don't call that series "Thermi" without reason

my brother used to run a gtx 560 155W card with a silverstone 500 80+ (not bronze) PSU without any problem, so I'd guess a good 550W one should definitely allow you to run a 480 even with overclocking

Don't dooooo iiiiit!!!! (Say it in slow-motion and overly exaggerated)

 

On topic: Don't do it. Fermi was from an age where climate change wasn't a thing and the ice was still present in the Sahara.

GTX 480 uses as much as 260 watts from 12v rail.  The CPU is probably powered from 12v as well, so reserve around 100w for it and the motherboard, and you're looking at around 350w power consumption on 12v alone.

 

That's 350w or 350w / 12v = 29A on 12v.

 

Look on the label of the power supply, if it says more than 400w available on 12v or if you see there under 12v a value of 30A or more, than it may be good enough for you.

 

But considering the age of that system, most likely that 450w power supply can only provide 250w-300w at best on 12v.

34A lad its a XFX ProSeries 450W

Then it should be OK. 

 

It should be based on the Seasonic S12II platform inside, which is honest about what it can deliver. If it says 34A, then it can provide that much on 12v.

 

I simply assumed you had some older power supply (older design) in that system, considering the other components and - no offense intended - your country.

Oh you can be sure i'm offended.
