The server grade PSs are not bad at all, but LONG term I figure on using the seasonics in actual computers once bitcoin mining gets to the point you CAN'T mine profitably as a non-big-company major farm operator.
I was actually doing research a year or so back based on computer builds to work on Distributed.Net (RC5), GIMPS (Mersenne Primes), and Folding@Home (+ curecoin, might as well get a pittance for doing what I was gonna do anyway) at the same time, and the Seasonics are what my research decided on.
AMD A10 (GPU running Dnetc, CPU cores running Prime95), 3x GTX970s (or whatever was going to be comparable at the time) for the folding.
Just turned out to be a research timesaver that the most common power supplies used in SHA256 and Scrypt mining were some of the SAME ones I'd already done the research on.

I'm actually, in final configuration, running 3 S5s from a pair of X1250s (I'm very conservative about power supplies, and like things to run COOL for longevity).
When I was initially TESTING them, I was running one at a time solo on a X1250.

isn't better to go with 1500w corsair? which has an efficiency even above platinum level? this for two s5 only of course but maybe it's better to attach the s4+ with it, so you can saturate almost the whole wattage and have a better hash per watt
it would cost less than two seasonic of 1250w, around 500 euro vs 400
How many PCI-e cables does that corsair come with?

I own one of the evga's nice gear.
8 right, but remember that you can use the other connectors for the two ways molex pci-e adapter, and there are six peripheral sata there, each one can support up to 132x2, because one 4 pin molex support around 132w
I don't trust Corsair nearly as well as I trust Seasonic. Corsair does NOT make any of their own power supplies, never has - Seasonic DOES and in fact is a OEM for other brands as well.
If I went with anything else, it would be the EVGA 13000 gold units a lot of other folks use - but only 6 PCIE cables (granted 2 of them have 2 connectors each) and the gauge of the cables doesn't look any bigger than the *8* Seasonic has..... dunno.
Seasonic has a better rep overall than EVGA does, but it's at least a fairly close competition there. Corsair isn't in the same ballpark on a LOT of their power supplies.

never had any issue with them, my 750 gold runs extremely smooth and fine since 2011, also they were using seasonic in the past as a manufacturer, but for their recent models they switched to flextronics
i have seen a good amount of people using serve grade powersupplies since they are build to run 24/7 so they are most likely to preform better are some points, i havent use them my self but from what i have seen they are pretty well build.
two of these will bitch slap the evga 1600 or the corsair 1500 or any seasonic

I'll definitely consider a server PSU next time around, but for my current needs, the EVGA 1300 was only $50 more and comes with a 10 year warranty, 8 PCI-E cables, and extra misc cables (I run the fans from the molex). I know these are platinum, but the 1300 GOLD is still a fairly good value for what you get, even compared to these. The 10 year warranty itself I think is pretty important if you're running the PSU near capacity 24/7.

I have the EVGA 1300 gold, no complaints. However, I remember when I looked at the EVGA 1600, it had a lot more PCI-e cords which would probably solve the double cable issue on the 1300.

50% load is actually the "sweet spot" on most Gold power supplies, but 70-80% is usually close enough.

As it is, the output air from my Seasonics is warm, but not very warm - and the fan doesn't seem to be spinning very fast. With a single S5, the fan was taking a while to kick on at all....

I would guess that you are right in the "sweet spot" for the PSU efficiency range, and should run "forever" that way (assuming you pay the electric bill).
Your choices sound quite reasonable to me.

When I got my first 3 S5s, I did some fairly substantial testing on them. I find they vary some from one to the next, one was soaking 620 watts at the wall the other two were under 610, when stock clocked. All were stock frequency running on the same Seasonic X-1250 and being measured by the same Brand power meter at the time. They all run a little different on temps, all with stock fan and the PWM lead disabled to keep the fans running at max all the time.
There is always some small variation from one chip to the next of the same design, process variations add up.

try setting the units on a thin mat. i had some silicone sheets.
i set the silicone sheet onto a flat floor then the s-5 onto the sheet.
thus all air pushes through the s-5 no air leaks out of the bottom sides.
some of that air goes up to the top giving 1 or deg cooler.
as long as the boards are under 65 it seems to be okay.
i got 58-62 with good errors

What would you define as good errors? I'm getting 0.05% now, is that considered acceptable?
just watch it to see if it declines .
if it drifts to 0.06 or 0.07 % no worries. If it goes to 0.25% try a slight under clock.
there is no big worry unless they go to 1 or 2%
Thank you! Will do further testing with some new fans today. I've gotten it pretty stable at 0.05-0.06%. One of the tricks, especially with 2 S5's sharing a single PSU (EVGA G2 1300) has been to put the fans on separate connections to the PSU instead of running off the S5's themselves. That way they are not sharing the power over the same cables. This helped errors come down a good amount - especially with the stock fans that are rated at 2amps each.
how has your gear worked for you over the last few weeks I figured I would follow up.
I wound up going back to the stock fans but under-volting them to reduce power usage and help with the sound. The error rate is still not great, but seems to be PSU related. The EVGA 1300 is capable of running 2 S5's, but it definitely starts to strain even with a slight over clocking. I'm still playing around with some designs but also waiting to see what the specs on the S7 will look like.
I am also awaiting the s-7. Sounds like you run the stock fans directly from the psu. this is smart if you do that as it will avoid this problem

Great ideas, thanks! I'm also trying to figure out some temp issues. One unit is running 60/60 right now, one at 64/51. Same exact fans - very strange. The unit at 64/51 is getting much higher hardware error rates.
I have 24 S5's that I use as my test setup, and on average I see a 1-2c difference between blades, no real rhyme or reason towards which side is hotter, etc. In almost all cases, if I see a big temperature variance, then I remove the heat sink from the high temperature board, re-apply thermal paste, and this brings them right back in line. Since you just bought yours, if you want to do this make sure to run it by Bitmain before doing so, so it doesn't invalidate your warranty.
