Is my PSU strong enough?

yes but berely. get a better one something like 600w or 650w

I would recommend a high quality 600w or 650w PSU.

Something from Tier 1 or 2.

What make and model for the psu? Same for the gpu.

yes a 500 watt psu can hold ur cpu well ,,, but it must be a quality 500w psu.... try buying 80plus gold edition psu

GTX 1080 is MIN 520w PSU.

So a quality 600-650w Would be recommended.

Will run cooler/quieter and much more efficiently.

NO, it's not enough for a GTX 1080.

Your PSU is fine for a GTX 1080.

There are some who under recommend PSU wattage for systems not thinking about headroom and longevity for the units.

I will never understand this.

They just plain work better with enough headroom.

One doesn't have to go crazy and get a $200 PSU to get good solid units.

A good rule of thumb is to add 100w to the recommended min PSU for the graphics card.

I have been running one of them for over 7 years now 24/7 so I know it's a solid unit.

And it's a proven unit with excellent reputation, you won't regret it.

The M12ii are actually quite notoriously noisy power supplies under heavier loads. Then again, his system is low power, and both the CX500 or M12ii would probably be quiet enough with his system.

Also, saying it is a "proven reliable unit" - where is this proof? Unless you have access to RMA rates and stuff like that, basing "proven reliability" off its following in Internet forums by many people who have a Seasonic bias is not any type of valid evidence of reliability. Nor can any type of quantified data on any power supply's reliability be retrieved from Internet forums since they consist of humans with flawed understandings of concepts in the first place and are such a miniscule population when units are sold in major volume around the world.

A system with a Ryzen 5 1600 and GTX 1080 aftermarket, without overclocking further, should consume around ~250W when gaming. With overclocking hardware this may increase to some over 300W but should not go far beyond 300W at all in the realm of possibilities. You are overestimating power requirements. I have analyzed power requirements thoroughly and am more accurate than the power supply calculators (which are inaccurate) you'll find on the Internet.

I don't go by what is said on internet forums and never did.

I go by my own personal experience that I had in the IT field along with 1st hand feedback from people I know that are still in it.

As far as the M12's, yeah they aren't as quiet as the newer models like the X-Series and Prime. They also cost a lot less too these days than they used to.

I am still running two of them personally, a 620W and 650W, a lot depends on the case and load as far as noise goes.

I do like the Prime and X-Series, very quiet, silent really unless you really push them hard. Will likely get a Prime as my next unit as it looks like the Prime is replacing the X-Series slowly. I am thinking the Prime series as they have all the different grades from Gold through Platinum. Will replace the old M12II 620W that's over 7 YO with my current X-Series 650W then replace that with a New Prime 650W Titanium. The M12II 650W still has some years left in it at 4 YO.

More accurate than the people who actually manufacture and do the testing on the various hardware BEFORE they are released?

When a Graphics card manufacturer lists a MIN PSU requirement it's there for a reason, they don't just throw out some random number or draw a number out of a hat and call it good.

I used to do that kind of R&D work in that field before I got out.

I got bored with it basically, that and the general working environment really tasked my tolerance level. As I got older my tolerance for certain things got a lot shorter. I completely abandoned the whole computer industry as a result. I am only here again to enjoy the forums and help if I can. And with all of the new stuff coming out that may or not be interesting to me, only time will tell I suppose. I do enjoy my own systems and gaming these days a lot more now that I am not in that field anymore.

Now I do R&D work in another field, one that is much more interesting to me. And I don't have to put up with people walking around trying to act smarter than they really are so that's a huge plus. Not my ideal working environment to say the least, I get to work at my own pace and choose what I want to do.

As far as Seasonic PSU's go I have my own opinion on them and that's what I use in my own machines. I did and do my own research from various sources that have proven to be reliable over time. I don't need people to tell me what to buy and what hardware is good or not. As for the other brands I have worked with them and even used some of them over the years in my own machines. I stick with Seasonic for my own machines and have for awhile now, I don't see that changing anytime soon either.

On the forums there are a lot of different opinions on various hardware, that hasn't changed over time, people are what they are and that is not going to change. The internet is what it is, the forums do seem to be much tamer than they used to be from what I remember.

Actually graphics card manufacturer recommendations arent very logical. I'm not the only one who thinks this, PSU experts on forums like Jonnyguru also are of like mind. GPU manufacturers have no idea what your hardware specs are, and some PSUs of the same "wattage" are more capable than others.

I put "wattage" in quotes because the "wattage" of a power supply is a non-stabdardized thing and there is no standard by which wattage is rated. In fact, it you take a random PSU without knowing it's label, you can't even figure out the wattage through testing since they can overestimate or underestimate if they want on the label freely. The wattage of a power supply doesn't exist, it's more of an idea used to Target a specific performance bracket on reviews, make a certain amount of money, or market.

The way I calculate power requirements is by looking at reviews for the hardware, mainly the CPU and GPU, reviews that both measure the individual components and the entire system. HardOCP, TPU, Tom's, and more sites are useful for this. The GPU manufacturer "min recommendation" is largely a value that takes into account the absolute scum of the earth PSUs that nobody should touch, and that is why it is so overexaggerated.

And believe me, I'm no fan of the CX500, group regulated PSUs I don't care for, but I'm just saying it would have worked.

The problem is people are buying those questionable PSU's, we see that even here and a lot.

Never overlook the human factor.

I wouldn't call GPU manufactures unrealistic because they have to build products for the masses so yes they don't know what the system specs would be for each and every person. They go by averages and factor in the human element and that can be worse than any junk PSU you can think of.

Being realistic a 650W PSU should be enough for just about any machine other than some multi GPU boxes. But we see people with 1000w and more PSU's running one GPU. I won't go into that any deeper than to say a lot of YT reviewers are doing this so that's were that comes from.

As far as the CX 500 thing, yeah it would work, but work and work well are two different things. In general PSU's work more efficiently when they aren't running at or near max. So I generally like to have some headroom in there so they run both more efficient and cooler even at max system load. They will also last much longer in general so buy a good one to start with and with enough headroom and one won't have to worry about getting a new one every build. Buying one PSU instead of 5, high quality units don't really cost much more than some junk units either.

As far as the wattage thing goes, that is more of what a PSU can handle and they build them to certain specs. The actual wattage and amps that a unit can handle based on a number of factors. That's were build quality comes in and as you pointed out looking at reviews like THG and Jonny Guru etc. Without going into it there are standard of build that are used for certain ranges, some overflow from the higher end units and some don't.

I remember back when PSU's didn't even have the wattage rating listed, they were just PSU's.

Today people have to have some sort of factor to look at so wattage is as good as any I suppose. But that's on a slide rule based on build quality and other factors so people need to be careful what they are buying.

Back to the human factor again so some need to be careful when recommending wattage ranges etc.

The human factor and or the human element, never under estimate those. (It's not the ones posting in the threads, it's more the ones who aren't that we have to think about.)

Less heat is always a good thing for electronics in general.

Would rather the machine run cooler in general as a whole, but then the are many factors involved in that.

The PSU running cooler is a big plus for those who don't have separate compartments in their case. That would be most if I was to guess. I doubt most people are buying the higher end cases. One of the main things people cheap out on along with PSU's and CPU coolers so that compounds the heat issue.

I wouldn't think a space heater would be a good thing for the machines in general.

Built a lot of machines over the decades and worked on even more so I tend to think about everything as a whole.

The cx500 wouldn't manage a ryzen & a 1080.

The point is though really if you can afford what , $600 worth of CPU & GPU alone then $60-70 for a new good quality PSU is a small price to pay for piece of mind.

The cx500 was never as bad as it was made out to be & doesn't deserve its tier 4 categorisation imo BUT it does have proven longetivity problems.

Cx650m is $60 at the minute , rock solid, loads of headroom , small price to pay IMO for piece of mind.
