Hi, my gtx 1080 will get here tomorrow and I forgot I got a 550w here, I saw that the asus version takes a bit more power then the founders edition, so my question is, will a 550w antec psu support an i56600kOC 1ssd 1hdd 2 fans 1 cpu fan AND the asus 1080X strix ?

I think yes but I would love to get confirmation on that.

Thanks.

It would be PLENTY. You could even get buy with a 400 watt PSU.

Hi, thanks for your quick response, are you positive about this? I asked on a different forum as well and got some mixed answers, some said that under heavy load it might have problems

550 watts would be more than fine even if you overclock the cpu and gpu till they explode and still you would be more than fine. Whoever told you under heavy load it was going to be a problem is speaking nonsense..

I'm 10000% sure. Two GTX 1080's use around 450 watts. A single one would use under 300 watts. I want to know what they were smoking in order to say a 550 watt PSU could have problems running a single GTX 1080.

The 980ti is much more power hungry than a single 1080.

That isn't a GTX 1080 and he still has plenty of wattage, he just didn't chose his PSU wisely for his needs.He chose the wrong PSU if he wanted a silent PSU. The G is same as the XTR btw.

It would be fine, but I prefer having at least a 650 just for extra headroom if you add more power hungry parts or another gpu.

Efficiency really doesn't mean anything.

Efficiency doesn't equal performance or quaility. It only means efficiency and really doesn't matter much when outside of extremes.

Efficiency really isn't going to save much money. It could take up to years to make up the difference between a gold rated PSU and a bronze.

Unfortunately, the numbers aren’t great at making the electricity savings of these units into a real factor in deciding on what power supply to buy or upgrade too.

With an 1000 watt 80 PLUS® Platinum power supply, you are looking at saving a grand total of ~$0.24 a day over a base 80 PLUS® power supply if your power supply was running at full load for 24 hours.

Now with a 500 watt 80 PLUS® Platinum power supply, you are looking at saving a grand total of ~$0.12 a day over a base 80 PLUS® power supply if your power supply was running at full load 24 hours. Now that does mean it will save you about ~$44 a year under that scenario to run a 80 PLUS® Platinum power supply instead of an 80 PLUS® power supply (~$394 compared to ~$438), however this advantage dwindles significantly again the more you move up the 80 PLUS® scale with 80 PLUS® Bronze, Silver, and Gold units. And again, the gap between single levels (Bronze versus Silver for instance) is even smaller.

That is a full load 24/7 which no one would be doing for your tpyical build on here so it would cost a lot less a year and per day.

Some PSU's are also underated like the Evga B2 and the Corsair CXM.
