Hello!

I put everything into Outervision and got load wattage of 340 and UPS rating of 650VA for PC only.

I have:
i7-4790s
GTX 970
12 GB DDR3 Ram (4+8)
1 SSD
1 HDD
1 DVD
20 something" Monitor

I just bought a EVGA Supernova 550 G2 PSU based on the amazing reviews[strike], but then read the terrible hold-up times and was concerned.[/strike] Upon further investigation, it may be fine. It's still on the PSU Tier list at Tier 1. Since the graphics card is a loan from a friend, I don't want to risk damaging it.

What UPS is necessary to protect it? Full load (i.e. gaming) 3 mins should be plenty because then I'd be using it and right there. 10 mins on idle in case of power outage while I'm AFK. I'm in the Bay Area, CA, USA.

I saw someone recommending:
https://www.amazon.com/CyberPower-CP850PFCLCD-Sinewave-Compatible-Mini-Tower/dp/B00429N18S/ref=sr_1_2?s=electronics&ie=UTF8&qid=1490377382&sr=1-2&keywords=cyberpower+850

but not sure if I can get something cheaper or if this was good for my PSU (something about Sine waves?). Thanks!

Most UPS depend on the PSU having sufficient hold-up time to keep the PC on long enough to allow the UPS to switch from the power line to the battery. If you get a PSU that doesn't have sufficient hold-up time, you'll need to get an on-line UPS that doesn't need to switch to the battery when the power goes out.

Those are insanely expensive. The cheaper on-line units will run about $1000.

Dang.... Well ,upon further investigation, it seems like the review wasn't completely accurate and some users believe it's fine. I'll try the PSU for now and see if it gives me issues. If it fails the first time I lose power, I'm getting a different PSU.

It's still Tier 1 on the PSU list, so it can't be all bad.

Do you know of any cheaper, but still good UPS than the one in my link?

The PSU won't be damaged by a power outage. In the almost cosmicly unlikely event that you are writing critical data to some part of the OS when the power goes out, you would lose the data that's in transit. That said, it's usually possible to recover from that.

Regarding the UPS, it's always best to get one that's a bit larger than strictly necessary spec-wise. The batteries age over time and lose capacity. Here's a very solid option for that type of build:

I use APC units exclusively at work, and they've never let me down.

I'm living in an old house in SF. The wiring isn't the best for all the modern appliances. Also, due to the storm, we actually had a minor power outage just yesterday. It was only out for ~10 mins, everyone on the block came out.
