What's everyone do for UPS protection?

I have a 750w UPS for my server room that can hold my existing server stuff for 4 hours, been meaning to upgrade to a telecom style 48v setup with some beefy 2000w+ inverters... but for now I simply don't have enough UPS power for a full rig.

Thinking of just buying a used 2200va unit or something like that. Really it just need to be enough to power it for a few minutes so it can shut down properly.

Just curious what everyone's setups are for power protection, especially those of you with multiple 6+ card rigs.
 
Why does a mining rig need to shut down properly?
No ROI for throwing money at stuff that don't matter.

If you must, worry more about restarting remotely.
Rigs should crash every now and then, or maybe
you aren't trying nearly hard enough.

Now run a mining pool or service like that, I could
see paying a decent UPS.
 
With that much expensive hardware, don't really want it going down hard if there is a power flicker or something. Power here is stable though so may very well just chance it for the time being but it will make me uncomfortable knowing it can go down hard at any instant. Especially in summer when the power flickers more due to thunderstorms.
 
I can't justify UPS power for all my mining gear, but I am looking at maybe getting a whole house surge protector. Not only do you have to pay for the UPS, but then you lose around 5-10% efficiency using it.

If you really really really want a UPS, then look for a like a 208/230/240v, single phase, 16-20kva UPS system. You can sometimes find them used for a song. And that will be way way way more cost effective then buying a bunch of smaller units.

Measuring whether or not you are trying hard enough by whether or not your hardware crashes is quite an arbitrary indicator. Also not a good one.
 
I don't have any hardware on UPS.
I used to put folding machines on UPS power and it just wasn't worth it for the few times a year there was a drop in power and it UPS would step in to sustain. That and you need such beefy UPS units to carry the machines.

I did spend $15 each on WIFI smart plugs. So if I get an email that my machine is locked up or off, I can just open and app and power cycle the smart plug.
Also, setting mobo BIOS to power on after AC power loss helps.

UPS units to sustain a miner for less than an hour... not worth it in my opinion. Even an occasional brown out will just take down your rig for a minute or two.
 
i have a cyberpower CP900AVR on my 3 rx 580 rig. i got it for free from work. i was testing my system with all cards at stock settings and it tripped the ups and shut the system down. ups for a 6 gpu system would cost a boat load! (note: system isnt fully tuned yet)

Now that's a great idea!

$170?! That's a hard pass.

Didn't say it was cheap ;)

But, honestly, $170 would ROI really fast if someone had 40 amps 240v of miners, and it's cheaper than running switched PDUs, like this one.

Seriously, Back UPS BR 800
 
Was looking at 2200va units on Ebay and they do seem half decently priced, just got to watch the shipping, some people ask like $500 to ship a $300 UPS. I'm not at a point where I need to go beyond my 1000va unit so guess I'll wait it out for now and see how much money I actually make. Ideally if I actually do make half decent money mining I may just go all the way and upgrade to a high capacity DC system using rectifiers and inverters. Been wanting to do that for a long time anyway. So if I can do it for virtually free then bonus.
 
Just typical house circuits, so I have 3 independent circuits with 3 x 1500VA, just because I have a lot of equipmnent. Things with multiple PSU's go to different circuits (so I can tolerate a breaker throw/meltdown). I use APC UPS mainly because they are easy to purchase batteries for. With that said the circuit boards tend to blow after the 2nd or 3rd replace anyhow. APC used to make consumer UPS's that allowed for battery expansion (to increase runtime), I used to own those, but not anymore.

This is way overkill for a simple scenario btw. Only mentioned because I have a lot of equipment (several servers).

GPU's are power pigs. Under load they will likely occupying more than double the wattage of a multiple CPU setup (even something relatively contemporary) with 128G+.

Heat dissipation to me is a bigger issue. So invest in independent cooling and/or adequate separately ducted ventilation. Everyone's threshold (of importance) is different. Power sags and heat can be your biggest enemy.

Spin up can be huge deal depending. I do recommend buying a reasonable power meter(s) (could be good metered PDU). It will go along way in determining what you should buy. Be aware of how load is distributed on multi-PSU setups, some are dual-active, some are active-passive.

And of course, be as "green" as you can be (I mean, nothing you're doing will be "green", but try)... that is, buy used where possible, nothing that used UPS's are probably NOT a good idea (though people have bought my old dead ones).
