I have replaced a PSU with Corsair RM1000 (80+ Gold). Now the power consumption at the wall is less (662-666 Wt), and HWE has been reduced twice (from 0.027% to 0.013%). It's all after 11 hours of running, will see what happen next. 
p.s. seems that after "halt" command the power consumption is about 150 Wt...

That's actually rather high for a stock S5, they're usually in the 580-600W at the wall territory. Have you got anything else on the PSU?

My S5 lost half its hashrate today. Its been about 8 hrs of reduced cycle. This is my first bitcoin miner. How should I approach troubleshooting?
Switch the power supply off. Count to 20. Switch it on.
If this doesn't help you might want to try another PSU, try powering one blade at a time, swap controller cables, swap controller ports.
It`s not a PSU issue, i have 2 s5 on 2 different PSU A 750w and a 1000W, and yes they drop to half speed alot ramdomly, ( NOT OC`ed ), sometime after 10-20 mins they will go back up to full speed, sometime not, and sometime totally freeze up and need a PSU reset.
i would have to assume it`s a firmware bug
on first gen firmware or Jan 7 firmware?
It happened to me on first gen, not much or very rarely on jan 7 firmware.
Yeah the latest firmware pulled out the majority of the bugs in relation to blade dropping but it seems not all of them. Recommended to upgrade to the latest if you're not already on it.

Just received my 3 S5's. have to say, very quick, live in NW USA and ordered last friday, (saturday in CHN) and already have. Amazing travel time imho. I went with the fed ex, as it was the lowest option. I have 2 of the 3 up and running, (i need a new psu) and they are both hashing very nicely.
Im using a 650W PSU with 1 and two 750's with another. #1=1162 GHS, #2=1154 GHS averages.
can we overclock these? What is the setting for overclocking?
Thanks

It might be in your case, but I've had random issues on one unit with "x", "-", blades disappearing, mining sporadically stopping - all went away after replacing the PSU. Worth a try if nothing else helps.

That was 33 days from out of the box to reboot.
Same here, had it running without a hitch for weeks, and a couple of days ago, I noticed it had halved hash-rate. Did a software reboot and all was OK until I noticed the same yesterday ... another software reboot and its fine thus far. A bit worrying if you are not keeping an eye on it though ....One of mine did this to me today.
I've had 1 of my 2 units do this twice now. It ran for almost a month with no issues, then I noticed it was only running at half speed. A reboot solved it for about 2 weeks and then it did it again. I now check first thing in the morning when I get to the office.
The only time my SP20s are down is when I update the firmware. Otherwise they have been rock solid. Received them a day after the S5 units.

Wow, I've not had uptime like that yet.

It's odd. I went from Nicehash and rebooting every few hours to ghash and once a day reboots to f2pool and 9 days uptime straight. Could be pool related.

Anyone put a S5 in an S3 case (with the top) and then see how well a push/pull dual fan setup works?
