lol that's ca don't assume everyone is from canada

 

 

i say 650W

[System Error Message]

600W from a good PSU. GTX 1080 TI is 250W, i'd put 300W for that to allow for overclocking and additional power use. The ryzen itself uses up to 150W (overclocked), but if you dont overclock its 65W, 95W if you clock it up without adding volts. The board itself, not so much. I'd put down 100 for the board including all the peripherals you can attach and power from it. Drives, 20W, fans approx 30W. All these are max values that may not be reached though but depends on your usage.

So at stock you have

250W+65W+100W+ 50W giving approximately 500W PSU requirement if you dont overclock.

If you do overclock, thats almost 100W more for CPU, 50W more for GPU giving a requirement of 650W.

A good 650W as many have said is a good option. An EVGA 650G2 is a good choice.

its overpriced compared to the FOCUS PLUS and the cooler master v though

650 would be nice and 750 would be the sweet spot if you wanna spend a bit extra.

WHY NOT

 

G3 550W is cheap though, only $60

550W for use as is.

If you want some overclocking, you might get a bit more (650W).

 

750W are not needed and enough for TWO graphics cards.

What are you calculating?! 100W for the Board?? SRYSLY?! Where should that come from?!
Just look at the heatsinks! The only thing that really gets warm are the MOSFETs (=CPU VRM) and the CHipset. But Chipset these days is less than 10W...

So the VRMs are things that really waste a bit of power but still we are talking at worst about 20W or so. With more, the Board will catch fire without decent cooling...

 

And even with your assumption that the Board will consume 100W, a 500W unit is more than enough!

And a decent one is specified for 24/7 at specified ambient Temperature. That is 40°C or 50°C for a decent quality unit.

 

Why do you want so much power? Don't you ever measure the rig you are using??
My is at around 300W (+/- 50W). And I have an RX480 with an i7-3930K.

Even with TWO Tahitis it's really really hard to get 700W out of the wall. I have to give the CPU like 1.4V or so...

100W because the board has various USB ports. Each standard USB port the board has allows 2.5W standard power draw. Some usb3 ports and charging ports more, dont forget fans, chipset and so on and other i/o that provide power. Read my wording carefully.

Yeah, but even with 10 USB Ports, you have something like 25W. So that's not that much. And some devices don't even consume 500mA at all. Like a normal Mouse and keyboard...

And fans? Are we really talking about 0.2A@12V worst case?? So even with 10 fans we are talking about ~25W at most...

 

All that just so that you can reccomend a rather oversized 650W unit wich isn't really needed in this case??
ONLY for Sledgehammer overclocking with no regards to life, you can think about that...

Ryzen is one of the worst examples for overclocking. If you are really lucky you can get 4GHz out of it. So around +10% more Clock Speed.

It's not worth thinking about it, however getting really great RAM is. THAT will give you way more performance than overclocking this CPU can ever do...

 

The only thing left to overclock is the graphics card. However, nVidia stated that that will reduce the lifetime to ~1 Year...

So you get a bit more performance but also sacrifice lifetime...

 

Anyway, a good quality 550W is more than enough.

dont forget the ram and the various devices on the board too.

The chipset uses some power, between 5-20W or more depending on the chipset (thats why a lot of boards have heatsink on it). The sound card and NICs use power too as they arent part of the chipset (chipset only provides expansion option but not the card/chips). Than theres also the board itself which does use a few watts. Theres also various IO on the board that do use power too. That is why 100W is a good max estimate though boards are designed to consume up to 150W which is why CPUs have their own power as they can consume a significant amount of power. I suggest looking up the ATX PSU specification to understand the amps given onto a board.

 

So normally the board uses very little power, but there are times when it uses a lot of power like when you connect many things to it and use a lot of the IO for instance. Or if you use all the ram slots and high capacity ram as well.

I ran overclock CPUs and GPUs for years. At the temperature nvidia defaults to for their GPUs it does shorten their lifespans. At the temperatures i run them it doesnt. Even on stock nvidia GPUs overclock themselves. From 1600mhz default boost to 1800mhz default boost. All my nvidia pascal GPUs clock themselves 200mhz more and keep those clocks 24/7 when under load. I can run the GPUs at 2Ghz and it'd still last a life time.

 

OP is using AIO with radiator and fans, that does draw more power than normal air cooling and it also means the OP intends to overclock far. Hence why my suggestion of 650W is a good estimate for a good PSU because you have to deal with peaks. Its not the average or typical power draw that you should consider but the peak which if reached will cause the PSU to shut itself off if it is over the PSU limit. Peaks are reached easily and last for short amounts of time. The other thing as well is that processors use more power as they heat up. Nvidia GPU running at 80-90C default setting will use more power than running under 70C. The CPU's power draw isnt that different because its only 8 cores but my 36 core CPU router shows significantly more power draw just by an increase of 10C from 60-70C.

And agian, not that much at all.

But the things with 20W are things like nForce 4, not something you have today.

Intels X79 for example is specified with just 7,8W

ONLY 10GBit/40GBit is noteworthy in power consumption, the rest not so much. Also every other component. What are we talking about? 1W, maybe two?!

And the board itself does not really consume much, because it's just a passive component with copper traces on it, no active device at all.

And the most notworthy thing, the chipset itself, is far under 10W. So the only thing that really is noteworthy beside the Chipset are the MOSFETs, especially the CPU VRM. The rest is just nothing.

 

I could find a Datasheet of a Realtek RTL8111 and all they say about 'average supply current' is something like 300mA@1V and 70mA at 3,3V.

Makes around 550mW - so around half a watt....

And according to the Datasheet it's at 1Gbps with 'heavy networ traffic'...

Have you any proof of what you are saying?!
Because I don't see any. I only see that you are accusing things that do not really consume anything to consume power. 

 

You don't seem to understand that everything that really consumes any power at all, needs two things:

a) a beefy voltage regulator, as next to nothing uses 3,3V for the core voltage these days

b) a heatsink

Everything that consumes a bit of power, will be heatsinked and not just soldered to the board.

And again, do you have any idea how much 100W is?! 

For 100W you need a really beefy heatsink for it to not burn!

A Radeon HD5850 should be close to 100W or a GTX 1060. Those Heatsinks are huge....

Though it's not in english. But you can use Google Translate and it works rather well, because both are Germanic Language...

The main point is that "nVidia says" that @ 100% Voltage the lifetime of a Pascal GPU is reduced to 1 Year.

And that's the mentioned 4GHz if you are lucky...

They do binning and use the better dies for their higher clocking parts like Threadripper and 1800X...

You can not get a normal 1700 to go beyond 4GHz at the moment, even with water cooling...

And we are talking about increases of 100-200MHz overall. Not really worth it...

 

With memory, there is way more performance to get...

chipset, 7W, Sound, Some watts depending on the speaker(s) it drives (I'll drop 10W here). 10 usb ports. 25W. 2 charging ports. 20W. Ram - http://www.tomshardware.co.uk/intel-core-i7-5960x-haswell-e-cpu,review-33029-13.html

At 3Ghz running at ram settings, i'd be more than the website listed so 10-20W is a reasonable estimate, 30W-40W with all 4 slots filled.

fans, each fan if at 0.2A 12V, thats about 3W each. Typically boards have 4 fan slots so thats 12W.

 

Now adding the basics up, 7+25W+30W is 62W for just USB, chipset and ram, excluding all other IO and devices on the board itself (the sound card's DAC does use power too btw. NICs use about 1-5W for gigabit NIC). USB 3 also has a higher output than the 2.5W per port usb2 has. Hence why i said 100W is a good max board use estimate as no one expects to fully utilise every single thing on the board filling up it's 150W typical TDP design.

 

PSU's power listed is the peak it can supply. Some PSUs specifiy a higher peak though otherwise not. For example say the system draws 700W peak on a 650W PSU. The PSU cant supply 700W and the caps get drained, causing ripples on the power output. This can cause a hang. The capacitors arent there to handle those sudden loads when a PC starts getting fully loaded, as the entire PC heats up so does its power consumption. The capacitors are there to ensure that the ripple is within spec and kept as low as possible to have as smooth voltage out as possible. They arent there to provide additional power for peak use which is why PCs dont power on immediately after you press the button as the capacitors must be charged first for the voltage to be smooth.

 

When talking about which PSU to choose, we talk about the maximum possible power draw as thats important to look at even if 99% of the time the power draw will be half of that. This is because that 1% of the time, if the PSU cant handle it bad things can happen ranging from surges to sudden power offs and drive power starvation causing drives to fail (especially SSDs) for instance. It can also damage the PSU or even the board/components.

 

I do EEE for fun. Capacitor smoothing relies on the capacitor being charged and discharged from a very small portion of it's capacity while keeping most of it's capacity charged all the time. Those capacitors you see on the PSU and board, they arent there to provide power for a second, they're there to filter and smoothen the voltage.
