Can you order from Scan.co.uk and Overclockers.co.uk?

Quality of power supply is probably more important than power these days. All of the component manufacturers are focused on power savings these days. Modern components use significantly less power than most users believe.

I have crossfired 7950 w/ 3770K all overclocked. The fan on my AX860 does not usually even turn on which either means my PSU is broken or the draw is not hitting the load cap for the fan.

 

That's because your PSU has the Smart Fan technology and it's also because your power consumption is likely not even exceeding ~550W.

No, I would rather order from stores in germany. Well, you can sent me the link and I would watch if the shop in my near has the psu.

Edit: Whats about this one http://geizhals.at/eu/sea-sonic-platinum-series-760w-atx-2-3-ss-760xp2-semi-passiv-a874979.html ?

750 is probably fine but you have to understand that you're also running drives and fans as well. If I OC my GPU's my 750w isn't enough and I'm only running 660ti's. Granted the newer GPU's do use less power but not 20-30% less in one generation. I would consider an 800-850w personally.

If you can afford it, then yeah that's fine. Just be aware that there's a chance of having coil whine.

I took that into consideration. I know what I'm talking about here. ;) Look at the review I posted above: they are showing the power consumption of the entire system. That includes drives and fans and everything else.

It costs 160€, so it's ok.
It would be enough for two 780 ti's ?
What would you *recommend* ?
Edit: recommend* - damn typos...

I already said that a good 750W PSU would be more than enough, as long as you leave the 780 Ti's voltages at stock.

 

Anyway, here's another option and it's an awesome one:

 

The 750W Super Flower Golden King Platinum for €154,17

 

To be honest, I would buy this instead of the SeaSonic!

Consumption and heat output (not peak temp) is pretty similar between 290X and 780Ti btw.

I'm not saying you're wrong. Just saying it's better to plan for worse case scenario. I get my information from real world experience on my last few systems. Everyone seems to be on this 'buy low' kick for PSU's lately. Yes manufacturers are cutting power consumption on parts but it's not safe to be recommending lower than needed power supplies. And I'm not saying he should run out and buy a 1000w either. An 800-850w Gold will suit his needs. That's all. I happen to know what I'm talking about. thumb.gif

Lower than needed? If he leaves the voltages at stock for his 780 Ti's, then his gaming power consumption will never exceed 600-650W. So, why get anything 'bigger' than a good 750W PSU, especially when he can get that badass 750W Super Flower Golden King Platinum? In the 850W range, he has inferior choices unless he wants to spend more than 150.

 

So, if he says that he will never overvolt his 780 Ti's, then he would be absolutely fine with the 750W Super Flower Golden King Platinum. Otherwise, yeah, it would be a no-brainer to go with a 'bigger' PSU.

Firstly, thank you all for your help. I will decide in the following days which Psu I will order. The reviews of the Super Flower Golden King Psu are looking good thumb.gif
