I want to know if a 600W power supply would be good enough to run a GTX 1080 card. Also I would like to know what the best 1080 graphics card is at the moment. I want to get the best card possible for my system and I want it to last me at least 2-3 years before I have to upgrade my system again. My specs are:
CPU: Intel(R) Core™ i7-4790 3.60 GHz 8MB
FAN: Asetek 550LC 120mm Liquid Cooling CPU Cooler - Extreme Cooling Performance (Dual Standard 120MM Fans (Push-Pull)
HDD: 256GB SanDisk X300 SATA III 6.0Gb/s SSD
HDD2: 1TB SATA-III 6.0Gb/s 32MB Cache 7200RPM HDD
MOTHERBOARD: GIGABYTE GA-Z97X-SOC ATX
POWERSUPPLY: 600 Watts - Standard 80 Plus Certified Power Supply - SLI/CrossFireX Ready

Some custom cards will have higher TDP, some not.
For non overclocked card (I'm not talking about factory overclock), they will be 180-230w.
Your PSU, have 2x12v rails of 24A. Each able to deliver up to (12*24) 288 watt. So it has some headroom.
If you want to push the card by playing with voltages and clocks, the PSU I linked, will be more suitable as it has single 12v rail that can do 650w on it. Though from what I've seen, 1080 does not benefit from extra power delivery and overclocks about the same on 180w or 230w cards.

Yes, even good 500w will be enough without overclocking.
Now, please post your PSU model or the picture of it with the sticker. If it can do 550w on 12v you are good.

This should be fine. it seems to be able (at least on the paper) to handle 250w graphics card.
if you want to be on the safe side and may be get into overclocking, you should buy something like

It's not that expensive also :)

I'm thinking about getting a GIGABYTE 1080. Because it's non-reference, would it take more power to run it, even with overclocking or would my power supply die on me?

Alright. Thanks for the responses. Just as long as my current PSU can support the power output of the GIGABYTE 1080, then that's all I care about. I'll think about getting the 650W PSU, but more than likely, I will probably stick with my current 600W PSU.

Than pick the answer you liked as solution to mark the thread as solved and help people that search for similar problem.

P.S.
When and if you decide to upgrade your PSU, post again as not all PSUs with same Watts are equal. Since 600 or even 550 high quality PSU can be a solution for your needs.

It'll run, but I don't know if it'll be safe or burn out your PC :lol:
Who knows, it's labelled 600w, what if it can't give over 450w? :p

Than he can sue them :p
Anyway, 1080 is not that much power hungry and will not add more load. So if he was using it for a while before, he can keep doing so.

It's not much of a risk for already working system.
That list, I'm not sure how I feel about it. It is mainly for high end enthusiasts crowd. For average people tier 3 and sometimes 4 is good.
I found my PSU in tier 3, though before buying it about 18 months agoI checked the very scientific approach review on the resource I trust and it was rated as one of the most stable and and efficient in 650w group ;)

Quick Story. Once of my friends had a PC built from Cyberpower. With an equally crappy PSU, if not the same one. First time he played a game, it fried his entire PC, even the Hard drives and RAM.

Morale of the story: Don't cheap out on the damn PSU, and if you do, don't say that no one did not warn you.

Quick summary:
We agree that this PSU is bad
We agree that OP would be better with new one
OP agrees that he needs to upgrade the PSU to something better.
We disagree only on one thing. Does he have to upgrade now or he can wait a couple of moths. IMHO, since this PSU has not died yet in a system with similar load, it probably can live another couple of months.

So i decided that I was going to get a new power supply. I liked your suggestion, but I wanted to get a cheaper one so I looked around on newegg and found this one: http://www.newegg.com/Product/Product.aspx?Item=N82E16817139148
Take a look and let me know if this a good fit for my pc and the graphics card that I'm thinking about getting or if I should get a better PSU than this one.
Could also do this one if the other one isn't good enough. http://www.newegg.com/Product/Product.aspx?Item=N82E16817139060

Just wondering why you chose those 2 over the corsair PSUs that I suggested. I haven't ever heard of those two companies before.

For that price I wouldn't go with a group regulated power supply. The Seasonic G Series 550 sits at the same price as that M12ii 620W.
