Will a 500W power supply support a Geforce GTX 780 Ti?

300W can support GTX 750 Ti due to a GPU TDP of 60W

GTX 780 Ti needs at least 550-600W Quality (80+PLUS Bronze minimum) due to a GPU TDP of 250W

What brand+model 500W do u have?

Nop it destroy computer you need at lest 1000w or higher wornning DO NOT USE 500w on gtx 780ti you need to search it your self or go on to youtube.

No, I don't think that it needs 1000 watts. That's just going to be a waste of money for a single 780 Ti. A 600 watt PSU is what's needed.

Besides, you're misguided if you think that the computer will be destroyed. One of three things would happen: The PSU would blow out, the computer wouldn't even start up properly, or the PSU would use a safety shut-off feature to prevent damage. You need to learn more about computers before you can assume such information.

a poor quality power supply without working or improperly set protections can kill components
mobo (possibly cpu/ram), gpu, drives or anything plugged into usb ports

GTX 780 Ti runs fine on like 650W if it's good quality.
Like Corsair HX or AX for example.
Or something from Seasonic or XFX.

If you are going to be buying such nice card to be safe go with a 800w power supply.

Overkill, you can run two GTX 780 Ti with 850W PSU. 650W is plenty for one.

i recommend you the cooler master tool which calculates the power needed. http://www.coolermaster.outervision.com/PSUEngine

And seriously ?! 1000W for a 780Ti ?! U mad bro !
a 650 or 700W PSU will be enough !!

I sead 800w and says 600w minimum on the manfacters websit plus it always good to leaf abit of head room in a power supply

Manufacture suggestion is there based on "cheap" PSU specs. So with a quality PSU, you won't really need that much power.

Example;
CPU max/tdp wattage
GPU max/tdp wattage
Factor in roughly 100W for the motherboard and connected component (HDD, SSD, Optical, Card Reader, RAM)

That is what you'll require. All that comes out to roughly 450W w/ high-end/high TDP CPU, like 95W + 250W for a GTX 780 Ti. So with a quality 600W or so, you will have breathing room.

Now if u are planning ahead for possible SLI setup; then by all means get a quality 850 - 1050 watts

I have a 780 Ti and have a 750 Watt PSU. That works great. You dont need something larger than that, usually.

Lol only if there is more than one of them. I have a 1000w because I'm going to sli mine in the near future. For a single card though it's massive overkill.

do not go by wattage alone

i would not trust a diablotek 1050w with a gtx750 in any system

get a quality power supply
look up reviews, if you cannot find any load testing reviews (via load tester and oscilloscope) do not buy it
