Where do you live, what's available?

Bitfenix Whisper M is a good start.

Also be quiet Pure Power 10, maybe Cougar GX-S.

400-450W is more than plenty.

500-550W to be "on the safe side".

Get a powermeter.

Measure your PC.

And come again.

Sorry, but NO, just NO.

3.Seasonic s12ii Tier 3

No, the S12II is shit -> old, group regulated unit without decent protection.

While the be quiet Pure Power 10 is quite good -> decent fan, good protection.

The 9 is in the area of the S12II, although at least it's not as noisy and has decent protection. Though group regulation doesn't make them both worthy to just think about.

You can run that PC on a 450W unit without any problems. The Corsair RM550x and the BitFenix Whisper M are good choices.

As for the PSUs.

1.Antec Edge 550w Tier 2

2.Corsair CXM Grey unit Tier 3

3.Seasonic s12ii Tier 3

4.Be quiet pure power Tier 4 i think

5.Evga G2 Tier 1

6.Used Seasonic X series Tier 1 at the time and still a gosh darn good psu

OR just go here Tier 3 above should be fine.

The S12 was bumped down awhile ago now. Not a good choice for a new PC.

For a 1700 with OC (you have a Taichi so I assume you're going to) and a 1080 with OC, I'd suggest at least a 550W PSU. 650W is fine and anything beyond that is overkill.

Thank you all for the assistance.

So i guess I'll get this

EVGA SuperNOVA 550 G2, 80+ GOLD 550W, Fully Modular

I am well aware of that..CXM Grey will do much better..

But in some cases if none of them psu are available except s12ii..u could always use it..it will be fine but its not the best at the given price bracket..

WIth that mindset you can also use every shitty overrated PSU. It will work. For a while.

And everywhere these things are available. That doesn't make it right...

So stop trying to defent recommending it. It was a Mistake of you and deal with it.

You also didn't mention something like 'if nothing else is available'...

since u claim to know so much about a powermeter, u know u have to do the math of the psu's efficiency aswell? the power drawn from the wall is not the power the psu actually is outputting ( under load )

some psus may give 600watts to the system while only pulling 480 out of the wall

its not about "measuring ur pc"  u gotta do the maths of everything combined ( that includes maximum watt per rail / amps per rail ect )

also most powersupplies that are advertised it depends on how their advertised, if an psu is advertised under CONTINUOUS 400watt that means it can 24/7 run 400watt without issues, however most psus are just rated for PEAK watts ,   if its 400watt peak it might be only capable of running 300watt 24/7

400watt is a risk(under full load) even if high quality components are used in the psu, point out

u need to take summer and higher ambient temps also in consideration

also trust me, ppl dont like jet engine psu's .. even if ud run it on a 400-450watt stable  it will turn into a friggen jet engine especially in the summer ( again full load ofc )

The total system power draw would be less than 350W and that's under full load. Look at AnandTech's power consumption benchmarks... system power consumption, with a much more power-hungry i7-4960X, was about 310W in Furmark.

Why are we talking about temps? How does that play into power draw?

that load is only with the gpu under load and the cpu on basicly idle ( its just furmark )

add the CPU 100% tdp to that and ul have ur actual watts + the ram + the hdd and all other components

second of all when a psu overheats it becomes a friggen jet engine, u wouldnt want a old 480gtx stock cooler @ 100% fanspeed next to u all the time now would u? same about psu that overheats there, guess u never really overloaded a psu to know how loud they can get

FURMARK DOES NOT STRESS THE CPU AT ALL, run Prime95 (SMALL FFT ONLY)+ furmark at the same time and ul get ur actual power draw

You're the one who's got your facts a little backwards here. You draw more from the mains (the wall) than your PSU.

Check out the guide to 80 PLUS efficiency pinned on the PSU/Chassis subforum and is also in my signature.

Stefan may sound arrogant but he does understand 99% of what he talks about, the rest usually coming from the fact that he's German and some info is lost in translation.

Not exactly a realistic representation... try Crysis 3 instead. Stresses both the CPU and GPU. Power draw is still under 350W:

And TDP =/= power draw. TDP is the measurement of heat output. Not power draw.

As for noise, that depends from PSU to PSU. There are a number of factors that contribute to noise produced; the type of fan or the fan curve for instance. The EVGA G3 is stupidly loud because of the implemented fan curve but units like the Dark Power Pro 11 or the Whisper M are extremely quiet. And no, if you overloaded a PSU, the protections would kick in and it would shut off. It doesn't ramp up the fans like a cooler does on a CPU or GPU.

now try rendering and running a high end game, ul get higher power draw,

yes psus can get loud as fuck as they are under higher loads, at apoint they will shut off yeah but before u even reach that point they get quite loud trust me lol

if u have a 300watt and u overload it with 350-400watt u think that thing is just gonna shut off straight into it? nah it will run the power but it will go insane on the fan due to the temps increasing, and then just shut off when it hits temp peak

Let's do the math then. Using Guru3D's benchmarks, we can calculate 125W for the CPU and 184W for the GPU. Both at 100% load:

That's a total of 309W. And knowing how little the other PC components consume, that's still well within the 400W parameter. And that's in a rather unrealistic scenario.

Like I said, depends on the unit. Some can be loud. Some can be quiet. You can't make a blanket statement. It doesn't work like that.

u know that a mobo uses 35-75watt aswell? ( depends on formfactor and blingbling stuff )

ram +- 15watt depending on how many modules  / ddr type

fans 3-5watt per fan +- average is 4fans these days for the case and lets say 1 for the cpu so 15-25watt

a 400watt psu would just run easily near its peak hence why i wouldnt recommend a 400watt , 450 min also with a 400watt u would have 0 space for oc

^ all is again based on full load ofc

but yeah, not recommended to get a 400watt psu when u can get a 550 watt for +- the same price and high quality components, its better to have some headroom with a psu in general so peak load is 90% ( also even quiet psu,s will turn loud if they get constantly run at their peak, especially with higher ambient temps like mentioned before )

450 should be ok but 400 will be close call > not recommended , u need to keep in mind the rails themselfs have limits aswell and the watt is the TOTAL output , u shouldnt make it a close call per rail either

I feel like that motherboard power draw is a gross overestimation...

Anyway, under normal gaming loads, he's right. 400-450W is enough. 500-550W would give you "headroom". Maybe if you overclocked everything and decided to render and game at the same, you'd be exceeding 400W... but that's a very specific scenario.

If you have a good fan and a decent fan curve, it's not exactly going to be loud... if anything, the fans on the CPU/GPU would be louder.

Why?
How much do you think the system will consume?

Do you think an i7-3930K with an RX480 and a 400W Pure Power 10 would work??

Quote

since u claim to know so much about a powermeter, u know u have to do the math of the psu's efficiency aswell? the power drawn from the wall is not the power the psu actually is outputting ( under load )

Efficiency is Pin/Pout = Eff

Wich means that the Power that goes into a device can never ever be less than goes out.

Wich means that if the Power drawn by the PSU is equal to the number on the Powermeter, the PSU is used in a safe area because it can not be higher than that...

And with what you say: With a modern PSU and 90% efficiency at 100% load and 450W, you can pull 500W from the Wall because 10% "gets lost" (=is converted to heat) inside the PSU.

Quote

some psus may give 600watts to the system while only pulling 480 out of the wall

That would mean an efficiency of 125% 

Not possible at all. Ever.

You may want to google "Perpetuum Mobile"

Efficiency CAN NEVER be greater than one!

No, you don't.

You just put the Powermeter in the Outlet.

Connect only your PC PSU to the Powermeter. Do some stuff. And measure what it draws. Easy as that.

Quote

also most powersupplies that are advertised it depends on how their advertised, if an psu is advertised under CONTINUOUS 400watt that means it can 24/7 run 400watt without issues, however most psus are just rated for PEAK watts ,   if its 400watt peak it might be only capable of running 300watt 24/7

NO!
Every named brand advertizes their PSU with continuous power ratings.

Even chepies like Xilence and Kolink rate their PSU at Continuous...

Yep, absolutely.

We ain't talking about nForce 590 or shit like that.

That one was a real hottie...

The only thing that can really eat some watts are the CPU Voltage Regulators. But with estimated 95% Efficiency we are talking about ~10W with 200W Load.

Yeah, with  up to low high end (1080) 400W is more than enough, combined with a normal Mobile/Desktop CPU.

With an HEDT it's close but depending on the GPU still possible. 

This thread is so full of fail my brain hurts.
