I have a 500 watt evga bronze certified psu and was wondering if I need to upgrade to get the gtx 1070.

My system

Fx 8320 cpu
8gb ddr3 ram
GTX 960 4gb
2tb Samsung hard drive

It can BARELY on the margin run it. But that's not what's important. Those power supplies are lower quality and not recommended to run a higher power GPU and system. Get a high quality PSU from psu tier list and get a quality 520w or 550w. The EVGA 550G2, GS and GQ are all good, and the seasonic S12II 520w or the 620 is the better option. Get the 620w, it's cheap and only 2 Becky fps ore than the 520. It gives you overclock and load headroom for a fx 8320. The Seasonic S12II 620. It's cheap and high quality

Those are good. I agree. Though the cheaper S12II is just as good and cheaper, but you loose 30w for
29$. So one buck per watt worth it.

I've heard people claim that you need a high quality PSU for this sort of thing. Its true, there's nothing wrong with that, but it doesnt have anything to do with build or component quality or even bronze, silver, etc certification.

Its about the amperage the PSU is able to give you at the 12v rail(s).

So yes, typically high quality PSUs are the ones that are able to handle demanding loads by power hungry graphics cards, but sometimes cheaper bronze PSUs can give you all the amperage and power you will ever need.

BTW, the Corsair CS650 can produce 51 amps @12v rail, and the EVGA 600B 49 amps.
They are both more than able to handle most systems with a GTX 1080 card.

I have no idea why you guys claim that only the highest quality PSU's can run the 10 series cards from Nvidia.
 


This one? http://m.newegg.com/Product/index?itemnumber=N82E16817151096
 


I said that in my first post. I recommended the s12ii in the first post. Also there will be some limitation but not major, like a pentium 4 and a 980ti haha.
 


The 1080 is less efficient than Maxwell, at least in terms of raw power requirement comparisons. The 1080 is rated for 15W more than the 980, so I'm assuming the 1070 is the same way compared to the 970.
 


Yes we claim to use the highest quality PSUs. Why? They provide the reliability and stability spend life for the system. Lower quality PSUs like the 600B and the CX600 are not reliable because of the poor quality of the capacitator S inside. The inside components are higher quality in the EVGA 650 g2 vs the cx600 because they use Japanese capacitators, and the CX use budget ones. You seem to be applying that quality means rating, but rating has nothin to do with quality. The S12II PSUs are good quality but are bronze. Getting the best power supply will ensure that the PSU does not fry your whole expensive system. The psu tier list/
Is a good guideline for PSUs, and so does jhonnyguru reviews. Do not look at just amps and rating and wattage, you must lol for quality components
 


It is true, his EVGA PSU will have no problem at all with a 1070.

However, what you need to realize is that rated amperage should be taken with a grain of salt (just like rated wattage). Overcurrent protection trigger points are usually set way higher than the rated amperage, which makes the amperage values on power supplies sort of fake as is (basically underrated). Amperage ratings aren't so much related to the point at which overcurrent protection kicks in; they are more related to the manufacturer saying, "Hey, up to this amperage we certify this PSU will have stability with its voltages". Which is silly, because many PSUs are perfectly fine when there is a faster amperage on that rail.

One would expect manufactures to set the overcurrent protection trigger point right at the rated amperage, but that's not the case. Rated amperage can almost be as meaningless as rated wattage. Rated amperage does serve as a guideline for progressive load testing for PSU reviewers, but it's plain silly that the number in and of itself has no significance.
 

You're completely missing the point and you misunderstood most of what I said.

I wasnt asserting that you should recommend something less than the highest quality PSUs out there.
I was simply stating that it isnt required to run the system stable with the graphics card and specs in question.
When we're talking about whether a PSU is capable of supporting the entire system at maximum load, those PSUs that you wont recommend and deem of lower quality will still do the job just fine.
That is the point that you missed.

I agree that the more quality components and japanese capacitors will make a product that is more reliable and will probably live longer. But dont make it appear as if the 600B or the CS600 are unreliable and will break or even that will cause instability in the system. You're presenting it as if it is a black/white situation where either a PSU is reliable or unreliable. This is not the case.

No I didnt assert that quality means rating, and if you read my post more carefully, you'd understand that.
I specifically said that "it doesnt have anything to do with certification (aka rating)" meaning that bronze PSUs can be more than capable of supporting the entire system just fine, and their certification is irrelevant to that fact, as it refers to efficiency.

I wasnt arguing against your recommendations and I do not care about toms PSU tier list. These are irrelevant and by mentioning them over and over again you are demonstrating that you are missing the point.
 


I didnt say it has no significance, I was saying it does have a significance.
Anyway, you are correct, it is a specification and one cannot take it as an absolute and correct number.
But that is why we always try to get something a little better than what we need. If you calculate than you need 600W you go a little higher and get 650W rated PSU, with a little more amps on the 12v than what you need.

Also, I didnt comment on the OP's PSU, so it shouldnt really be a reply to me when you said "it is true his PSU will have no problem at all".
Personally I would recommend a 600W PSU even if I believe 500W is enough.

What you said about the overcurrent protection is interesting and I have to agree. Nothing more to add.

Hopefully there is no more confusion about what I said.
 



So yes or no for my power supply. Do I need to upgrade or can I get by with mine.
 

You dont need to upgrade per say, but I personally would recommend to upgrade only if you can spare the money. If anything just for being sure that there wont be any issue in the future, and giving you the ability to overclock/upgrade your system.
 


I just want to get buy for like a month after I get my 1070 without any overclocking and then I'll buy a really nice modular power supply when I get paid.
