cyberdimensions Go ahead and close it. I appreciate everyone's input, the part is ordered, and I learned a good bit. And yes, I didn't respond to any comments about not having a UPS, since, as stated correctly by Heavy Hemi, I was asking advice about what to replace my current UPS with, not whether I should just not use one.
Can I quickly ask, with the one you are currently using, which I'm having my eye on for my main rig, why did you leave that one for the more expensive one? Are there huge differences let alone the $200+ price difference? Features, etc.

My current one is the APC 1300VA 780 Watts. Running Timespy sucks over 800 Watts, that thing just can't handle it. The SMT1500 just has better internals and more batteries, that's why it weighs twice as much as my current one. Maybe I should start a thread now asking whether my desk will be able to hold 75 lbs of UPS, haha. You could try getting the Cyberpower 1500 900W unit that was recommended by others in her, but if you continue to use SLI, don't get the one I have, it just doesn't have enough wattage. 900 Watts just wasn't enough for an upgrade for me, I wanted some headroom and I feel the 900 just was cutting it close. Anything above 900 watts is just in a different price league.

Oh ok. I thought you said you had the CyberPower CP1500PFCLCD PFC Sinewave UPS 1500VA 900W in one post and that was the one I was looking at. Honestly, I don't always fold on the main rig but sometimes I do so idk what to do because this is more in my price range but if I were to double that, I'd have to wait a bit longer. Decisions, decisions....I think it will be a while before I grab one but it will either be the CP1500 or something higher as you said, in a difference price league to give more headroom.

Just pick one up at best buy, put it under max stress and see if it can handle it. If it can, keep it, if not, return it. Make sure you can return it before buying it of course.

I use a Cyberpower pure sinewave UPS - can't remember the exact model # of it and because of where it's located here it's tough to dig out to see all the tags on it (sorry), but it provides around 1450W of power delivery. My rig uses somewhere around 1000-1050W, but I like to be safe when it comes to the UPS / PSU setups as you can really walk into some instability issues if you don't ensure good, clean power.

Probably similar to: I've since replaced the batteries with the 9ah versus the original 7ah. The most I've pulled from it was just under 1200 watts while folding with 3 GPU's and 11 cores on the processor....Then cut the breaker to the UPS outlet...it held up for 5 minutes then shut down the PC properly. I call that good.

Another couple of questions come to mind on how to test this. Do you hook everything up and just pull the plug from the wall outlet to engage the battery to see if it can hold up or that's not a good idea? Also, if I'm close to the limits of a UPS while folding which I don't most of the time on the main rig since it's in use but sometimes when I leave, I leave the rig to fold and if a storm comes through and takes out the power, is there a way to pause or disable folding while it stays on and eventually powers down on its own properly when it comes close to the end of its battery charge?

For those of you who don't own a UPS...you should get one. Short read: Power Distribution Technology is changing where you may see more small scale / small time (1 to 5 seconds) power disruptions. Long read: The power generation and distribution industry (aka your power company) is moving to a technology known as a "recloser" or autorecloser ( https://en.wikipedia.org/wiki/Recloser) This is replacing/augmenting conventional fusing and circuit breaker approaches. Basically, these devices work in concert. When a power line "fault" (aka a short) is detected, they will interrupt power in a controlled fashion attempting to isolate the segment where the fault is. In the majority of cases, the power line fault is temporary and can be "burnt off" if energy is allowed to flow (a small tree branch, an animal, etc.) You would be surprised how many power outages are caused by "super squirrel" who makes the jump, and just brushes phase-to-phase causing the fault. The net effect for the home user will be: 1. A brief interruption of power (a few seconds) when the initial fault is detected 2. A resumption of power 3. If the fault persists, an approximate 30 second interruption of power 4. (2) and (3) may cycle multiple times if the fault energy is decreasing (not all reclosers can measure fault energy) 5. Voltage may dip or spike as the large circulating fault currents are flowing. This could cause an under volt, over volt, or both depending upon where your house is in relation to the recloser(s) 6. If fault cannot be "automatically" cleared, trip main breaker/disconnect and signal serious issue to control stations In the "old" way, a fuse and/or breaker/disconnect would pop, and the electrical linemen would have to "walk the line" looking for the fault downstream of the last popped fuse/breaker/disconnect...and could not reset the fuse until the fault was cleared. This could take hours depending on how many fuses/breakers/disconnects popped, and how remote the area was. The "new" way allows for the faulted section to be isolated, the non-faulted sections to be restored, and the electrical linemen only have to walk a small section of the distribution line. I live in Central Florida, and can verify that these already exist in my power grid (as my company sold them to Duke Energy).

There is a setting in the folding @ home client control app: Configure --> Advanced --> Power (checkbox for pause while on battery power)

Wow. Thanks for all that info. So you're basically saying, lots of upgrading is on going and something can happen during this transition. So it's best to grab a UPS during these changing times. Did I get that right? ksgnow2010

Yes and no. If they do it right, you won't have any disruptions during the upgrade process. However, after the upgrade process, interruptions like described above will be common versus just losing power for a few hours. A good UPS will keep your PCs running during the brief disruptions and will compensate for the over/under volt. GTXJackBauer Awesome! But how would it know this? Script?
No script...the folding @ home app will pause automatically on battery power after a bit.

Powergrid systems. Since my SR-2's hungry power needs, the APC SmartUPS 3000 served me well. The studio was upgraded to delta power so naturally we went with a shipboard UPS rack and couldn't be happier. It took a direct lightning hit to the main tower (seven bolts total) and we only lost a NIC due to a heavy side flash to unshielded CAT6 line running parallel to a plenum. http://www.powergridm.com/rugged-rackmount-shipboard-navy-ups-2u-3000va-2400watts/ When you have hundreds of thousands of dollars of equipment at stake, this is a small investment not only to prevent damage but downtime.

I wouldn't just pull the plug with a heavy load on it. You can damage and 'arc weld' an outlet doing that. Most UPS's have some sort of built in self test utility. For testing run time. I did this purely as a worst case scenario. As to your other question, as far as I know for consumer UPS systems, there isn't anything out there that allows you to shut down or pause applications running based on a signal from the UPS separate from the OS shutdown commanded by the UPS.
