Given that Johnnyguru measured the PSUs you're recommending as being vastly more "noisy" than Seasonic's cheaper offerings (as in 50mv of 12v ripple for the Be Quiet! unit and 25 for the Seasonic unit, quite a stark difference), I would question that reasoning as justification
Okay, they hit back in voltage regulation, but not by much, and frankly I'm more concerned about ripple anyways. Since you mention "noise" you are too it seems. By that standard, the Seasonic is a vastly superior PSU, and would be even if it was the same price, or more expensive. That it also happens to be cheaper as well isn't a bad reason to consider either.
But that's neither here nor there. Forgetting the fact that 50mv ripple isn't even stellar in the first place, and that many 80Plus
Bronze units manage that, the simple fact is that if you're not OCing, you only need a PSU that's not going to physically break the components. Do you have evidence that something that merely meets or somewhat exceeds ATX12v standards will actually endanger a Maxwell card? If it's just "playing it safe", then why not set the bar way higher than you have? Why is one arbirary place the correct place to set it (even if those Be Quiet! units' mediocre performance doesn't set it enormously high)?
It might be nitpicky, but then, aren't you being nitpicky for criticizing the choice of 80+ Bronze units that are perfectly adequate and 1/3 the price of your suggestions? There's no evidence they'll fail to more than adequately power anything.
The be Quite power supplys are a suggestion - as i said the Seasonic is a good DC-DC power supply. What makes the power supply in usa that expensiv is for most the exchange - what makes the power supply it self that expensiv - warranty, components circuits and the fan (a silent wing 2 fan costs alone 15€ on the aftermarket and the silent wing 3 fans arn't on the market jet since they are only used in the powersupplys right now)
If you are concerned about the ripple you should look up the
be quiet! Dark Power Pro 10. Well more expensiv in the united states.
Anyhow the limits of the ripple arn't reached for the SP 10. It is a very good consumer psu with silent attitude.
Yes ATX12V standards are also matched by china crackers. But this doesn't say they blast after one or two years since the capacitors make the dingdong. Since Seasonic for example produce their psu themself they have good quality. There arn't that much psu manufactures who provide good quality. Some like HEC even have problems with solder quality. Or the pcb material where the componets soldered on get crispy after a certain time.
And yeah we like to discuss psu's and other hardware related stuff - by no mean i'm a expert in this topic - but we have a couple of people whom are employed by psu manufacturers.

Here is a german article of Maxwell power consumption and how powersaving is achived.

look it up with google translation
There are flanks of 100 to 350W in a millisecond. The voltage have to stay on 12V or the current would break components. The vrm of the grapic card stabilize it but it has a feedback back into the power supply. Therfore you should go for a good modern psu if you by such a gpu.

Well if you think that, you might as well just recommend everyone buy a WD Green, since apparently names that designate design differences are just marketing. What? They're 5400RPM drives? Eh, it's just a marketing number. Amirite?
Of course the answer is no. There are significant differences, not just in peak throughput but in random reads, between drives in both sequential and random read/write performance. Samsung Spinpoint F1s actually beat out just about anything on the market for 7200RPM drives, but unlike Caviar Blacks, tend to be very expensive drives, instead of just moderately more expensive than the cheapest thing you can possibly get your hands on.
My storage drives tend to see heavy use for more than just dumping one's terrabyte torrented movie collection, so I tend to care if it can hold up well to secondary gaming storage use and the like. You may not, and that's fair, but...
You are right about that, but you have conditions in the use for your hdd's - yes the WD Series differs a bit in read/write/wattage consumption/noise but this is nothing a usual consumer is up to his needs, since for him it is only storage, and this should be as cheap in capacity to price. If you don't have special needs for it you can go for a cheap shot

and no drive is ever going to achieve that in real world use anyways, because no one sits around spending their days doing large sequential reads and writes. In real-world use, the 850EVO is often no less than 20% faster than the drive you suggested, sometimes substantially less, sometimes a little more, but generally for cases where it matters, random operations that are going to be less than synthetic benchmark ideal situations, that difference manifests pretty clearly in testing.
I could see cheaping out on bulk storage somewhat, but on your SSD? I'll spend the $20 more
In real-world the 850EVO isn't better since you will hardly notice the difference - the little better benchmark notes arn't a drawbacks for a gaming rig. For a normal user only read speed is usfull (what is notable in boot up time for the os or a savegame) and they are caped anyway by the Sata III port. So there is no real difference if your Windows need 16,5 seconds to boot with the Samsung SSD and 17sec with a Crucial. You also won't notice if a savegame is loaded 100ms faster.
