520w fanless seasonic, pushing the line for this system?

SPCR has $20 extra off with combo code for this, total of $40 off, and I've been wanting to switch to an r4, of which I will be fitting in 1-3 Corsair Air Series fans added in.

Would it be unwise to purchase a 520w fanless for a heavy gaming rig like this? I plan to be playing Elder Scrolls online with this setup, hopefully, when it comes out which i assume will be one of the most demanding MMOs of its time. Chances of it overheating? What happens if it is overloaded exactly? Chances of CPU or GPU at this range increasing much further in power requirements over the next 2 years?

I've plugged specs in extreme's PSU calc and it cuts it pretty close. The wear on the PSU as it states scares me, as does my overclock extra wattage (of which I may tone down to Max I can get on stock volts). Do PSUs degrade 10-25% over the course of a year or so with gaming use as implied from the extreme site's footnote?

That power supply should be fine and a great buy. Your 2600k is at most 150W OC, the 670 200W (OC), and the rest of your system something like 80W. That is 430W everything running flat out, which is a fantasy . If you were to SLI 670 you probably would get by fine, but you may want a 650W in that case if just for the number of PCI-E connectors it would provide.

These Seasonic should age very well as they use high quality caps, so I wouldn't worry on that. These PSU calcs over-estimate the power drawn by components.

I have a 2500K@4.5GHz, a max OC 660Ti (about same power as 670), 4 spinning disks, 10 fans, SSD and I the most I can draw is 350W and that is with Prime95 and furmark running simultaneously,

I was hoping that was the case. Anyone have further information on this?

What about it possibly overheating? Being in a padded case and all with a big GPU on top of it practically.

Now that is a good question. I would be interested in hearing any experiences on that - I have an R3 and was considering a fanless supply too, but didn't get as far as you

Really hope I don't step on my feet with this one. I think I'm going to order the combo, I don't see GPU or CPUs in the future being much more power with the way things have been going. I never plan to use SLI unless things dramatically change, nor would I ever want a dual GPU single card. The fractal r4 seems like the case to be buying considering all of the fans are/can be 140cm, Is the general consensus still that 140 fans in general are better in pretty much every way other than price/small watt increase?

At $120 after discounts plus shipping, not that bad a price for an 80Plus Platinum PSU.

My other thought though is that if you forgo Platinum and just go with Gold, you can spend something like $60 on one that will power your rig.

Noise-wise, you won't hear the PSU fan over all your case fans and your GPU fan, so IMO that's no reason to go fanless.

What Zap said might be true but I am a happycamper with my fanless Kingwin Stryker. So much more quiet after removing the crappy Antec Earthwatts 650. My front fan is the loudest but very manageable.

Fanless PSU's are great, but you'll need airflow inside your case to keep it cool. Just make sure you have a few big fans in the front pushing air both over your PSU and into the GPU.

Not for the high quality gold/platinum units. SPCR tested a Seasonic X-400 in a hotbox (i.e. no exhaust fan), and they could only get OTP to trip if they pointed a hairdryer at the unit while running full load.

That is skirting the point of a fanless PSU for the OP's rig.

3-5 case fans and a triple fan graphics card and a CPU fan?

I think a PSU fan is the least of his worries.

To answer the OP, yes it would be unwise, because you are paying more money for zero gains. Why zero? Because your system isn't quiet enough for you to hear a PSU fan, as long as the PSU you use isn't one known to be noisier.
