I saw someone selling a Seasonic Snow Silent 750w Power Supply for $200 AUD. I am keen to buy it do you think it is a good deal? And would it be enough to power a single GTX 1080?
 
Solution
It is a top-notch PSU, and is able to power not only one GTX1080, but even 2 in SLI. The price is not a steal, however - it costs approximately $150 (200 AUD) brand new. And this guy is selling it at this very same price.

Also, you probably don't need so expensive PSU - there are cheaper models out there which also provide excellent quality and are a better deal overall - not only from Seasonic, but also from EVGA, XFX and Antec to name a few.

What are the rest of your components?

He says he won it a few weeks prior and it is completely new and unopened. I am saving up to build a desktop around $2300 AUD. I am planning to buy the components at around Christmas, (probably going with a 760T White case which is what made this white PSU catch my eye).

Whoops accidently picked best answer, meant to click reply clicked without looking ;/ oh well. I usually buy my hardware from MSY in Australia if not PCCaseGear.
 


The Antec is also made by Seasonic and is a good quality model with more than enough power for your needs. :)

Everything seems to be expensive in Australia. :) That would be a good PSU, even if it's not quite the best price. And unless you're powering some crazy overclocked AMD FX9590 which is drawing 400 watts on it's own, then yes, it will also power the new GTX 1080. If I read correctly - the power draw from the GTX 1080 is actually quite a bit lower than the GTX 980 due to the 16nm process - it requires (in reference form) one SINGLE 8 pin PEG connector - and draws on average about 175 watts total.

That means - on average - and assuming you're targeting a 60% load on your PSU, a Skylake i5/i7, SSD/HDD/GTX1080 setup should only pull (worst case) about 350w or so and thus only require around a 550w PSU.

Insane. :) In a good way
 


1080 power requirements are higher than 980.

Ah nuts, you're correct. I was thinking the 980 (165w) was closer to the 980ti (250w) - apparently it's not. What I meant was that even though the 980ti has a higher power draw, the 1080 is significantly more powerful. What you have with the 1080 is 980ti (or higher) performance levels at the power draw of a slightly OC'd 980.
