the current 1060 you have has a tdp of 120 and that 1080 has a tdp of over 200W. You might want to upgrade to a 650W PSU just to be safe.

That PSU doesn't look very good. I can't find much in the way of a review, but it's only rated for it's max power output at 30 C (a decent PSU should be rated to at least 40C, or even 50C).

You need at a min of a 550W good quality PSU with a GTX 1080.

But on gigabytes website it says 500w is enough so i am kind of confused.

 

[Kashimi]

It says 500W because it goes for the absolute lowest possible required. You have to remember that the power supply isn't 100% accurate in transferring power. That's why you get power supplies that are rated 80+

You have to account for the fact that not all the power from a power supply can be converted to your components.

Will 600w work fine?

 

[Kashimi]

What's your budget for a new PSU?

 

[zeronates]

Here in Singapore its $80 for a 600w

 

[Kashimi]

I cannot help you find a power supply since I don't know what kind of electricity or plugs you guys use over there. If you can go a little further and get to a 650W that is well built, I'd say go for it, but if you can't try to find a well built (read the reviews) 600W PSU.

We use 3 pin UK plugs here on 220/240v 50hz

The minimum PSU recommended by Nvidia isn't necessarily a bare minimum. They don't know what else is in your system so they tend to overestimate a bit. And a good PSU should be able to output its rated power, even after taking losses into account. The problem is people buy low quality PSUs that can't reliably output what they say. In the example of the OP's PSU, it is only rated for 500W up to 30C. Given that the PSU will likely almost always be operating with a higher ambient than that, it effectively isn't a 500W PSU anymore. To be honest it'd probably still work, at least for a while, but I don't know how much I'd trust it personally to run that system.

A high quality 500W would be fine for that rig. ~100W for the CPU, ~200W for the GPU, ~50W for everything else.

Could you recommend me some good PSUs?
