Is this PSU enough for my build?

[Gbergz]

Hello, this is my first post here! I'm building a PC & i'm wondering if this PSU is enough for this PC?

Thanks for the help. :))

It's way overkill. A good 450-550W PSU is plenty.

So i will be able to run this PC with that PSU without any problems?
I'm looking to overclock it a little bit ofcourse.

[xdeathshot20]

psu is fine.  plenty of power for your system even if you plan on overclocking

Well, yes. But you're wasting money by doing so. Overclocked, 550W is plenty, 450W should also be fine.

More PSU than you really need for the build, if you found a good deal on it go ahead it's an excellent unit... it'll just not be as efficient as you'll always be using about half of its capacity.

[orbitalbuzzsaw]

You could drop down to a 650W or 550W unit and save some money.

[Praxis727]

I can agree with a 650.  if you are planning to overclock than a little extra overhead is good for stability.

The RM650i would be a better bet for that much money. You don't need 750W.

I'd disagree with the idea of getting a 450W if you plan to OC though. 8700Ks OC'd use a ton of power as do 1080 Tis.

Extra overhead won't do any good for stability. Good regulation, good transient response and low ripple will.

Thank you for the answers guys! Really appreciate it.

While this is true in general, also too little overhead can hurt things. You don't want your PSU to be operating at 100% all the time. Thus having some overhead will allow a PSU to run at a much lower capacity, and will prolong the life of the PSU. So I would never recommend going with a 450 or 550 as some have suggested. What if OP want's to add some HDD or SSD's in the future? What if OP wants to add some other stuff? To me, spend the extra $20 simply for the ability to add components.

So, a PSU rated to run at 100% load 24/7 at 40°C for 7/10 years shouldn't be run close to 100% load? Within that time, it's quite likely that the ATX PSU standard has been replaced. 

You spend those $20 to gain nothing (HDDs and SSDs draw next to no power), while I have those extra $20 that I didn't spend for no real reason.

Can you show me where a PSU is advertised to run at 100% 24/7 for 7 years?

 

If you did a little research, you would find that PSU are most effiecient at 40-60% of their maximum efficiency. If you have a 450W powersupply running at 90% all the time, it's much less efficient then a 750 running at 50-60%. But more power to you  man if it's working for you!

Well, @Stefan Payne has that BitFenix box, and I'm fairly sure @jonnyGURU has said something along those lines earlier. 

If you look at actual measurements, you'll find that the difference in efficiency between running a gold rated 450W, 550W and 650W at a 400W load is well under 1%. Here's Cybenetics' database, have a look. https://www.cybenetics.com/index.php?option=database

Interesting, i'll have to do some more research. I guess I should downgrade my PSU LOL

275 w for vid card under load and 150w for the processor,  12w for 4 ram sticks, another 12 for 2 ssds,  30 to 80 for the mobo.  This isn't a 4 core low clock setup.  These are tested numbers not pcpartpicker values.  getting close and that is not counting full load or spikes,  Yes you could do 2 780tis and a 4770k no rgb ddr3 2 stick of ram on 750 watt power supply,  but i wouldnt say that it is the same now adays

LOL OKay i'm no PSU expert, but that just says that it can be kept on 24/7, but it says nothing about at 100% usage! 

 

And geez, almost impossible to read.

 
Give me something real, as it's just not there. PSU companies don't advertise their PSU's being good at 100% for 7 years.

Tell me more about where you got those numbers? Because it's not from the real world. 12W from the RAM will heat them up to much higher temps than they actually reach. Most peoole do in fact not run ATTO or Crystaldiskmark while gaming. Motherboards don't draw nearly that amount of power. Worst case scenario with a bottom of the barrel absolute garbage underspecced, you're still looking at under 30W for the VRM. With a higher end one, you'll have a more efficient VRM. 

Here's an overclocked 4960X platform, and this is the wall power consumption. The DC power will be ~10% lower.

The rating they give (the label, where it says the output) is for continuous power. The thing in the picture clarifies that they actually mean continuous operation, when they write continuous.

Continuous in the PSU world = 100% constant

3w per stick.  pasted all over the internets.  multiple vids.  Also, they are rgb trident z so you should account for the lighting which will bring it back upto 4w.  DDR4 takes less power consumption then three.  Also, what world are you living in.  Motherboards do draw that kind of power.  Every capacitor or trace causes a resistance.  Power isn't just drawn but resisted.  Pci slots, bios, on board graphics acceleration, chipsets sound cards, bluetooth, wifi, power to all open ports Motherboard????  https://us.hardware.info/reviews/7605/17/intel-z370-motherboards-round-up-17-times-coffee-lake-power-consumption  That is one of hundres of other benchmarks.  I was being kind at 80.  Dont spout a bunch of garbage or call people out when you havent done any research or have on hand knowledge,  There is a good chance at 550w he would have been just fine.  There is an equally good chance that he wouldn't have.  Nothing you buy should ever be run at 100 percent.  That is how things break.  Less noise when your fan isn't on 24/7.I mean how long have you been building computers to be calling people\out on something they have been doing for 20 years  More reading and less I think.  So yes, 4w per stick 80 to 100 on normal game high end graphics load, 1080ti's are thirsty and Fat cores mean fat fuel needed.  Also has the highest clock of any standardized chip on the market.  I am ballparking at 520 or so and that is without counting fans, or cooler or hard drives,  or light strips, and to be honest i low balled some of those numbers.  It's all out there to read. And usually there would be some fluctuation.  But the guys that test these things aren testing from the wall and from the psu and from the other peripherals not the vrms.  So 10 percent is a little exaggerated as they are not likely doing this in there basements.  Sorry if i went off a bit but research before belittling someones reccomendation

You don't know that.

You can't know that.

You have to look up the Efficiency "Curve" of the PSU!

 

And what are we talking about?! 1% Difference, maybe two?!

1. I'm doin two 7970GHz/280X on a 550W - and still be under 550W!

2. Those values for the SSDs are peak/maximum values. And if you look at the Datasheet its more like 3W for active write (1TB) and 3,3W for Active Read (1TB) of the Samsung 850 PRO and Rated DC is 1,5A for +5V. So less than half of that it really uses.

3. 30-80W for the MoBo? What in the world could consume that much?! We don't have heatplates like the nForce 590! And if you'd look at a Graphics Card with 30W TDP, you'd see some serious heatsinking, for example this Gigabyte 1030 low profile. And that is a 30W TDP Card or so, for 75W (like 1050ti), you have some really big Heatsinks.

4. Load spikes is not something you calculate the PSU for, because that is what the capacitors in the PSU are for.

5. Look at (the old) Corsair RMx 550 and 650W Review on TPU and THG, you won't find much differences, in this example, it seems that only the Primary side is different...
