PSU and... UPS? Voltage regulator? Surge suppressor?

Hello,

If this is the wrong section to be asking about devices mentioned in title, please move to the appropriate section.

I live in a fairly new (~decade old) house in the Silicon Valley of California. Contrary to what some people would think, power isn't perfect here; we get outages a few times a year. During rare (~once a year) lightning and thunder "storms", lights dim a few times, and am hesitant to power my computer during those conditions. I've lived in areas with worse power, but I've been becoming paranoid about what I should be using as far as power outlet inputs go.

I'm currently running my computer off an APC surge protector/suppressor, and it's been working for a little more than a year now. Green light still going. That suppressor is plugged into one of two wall outlets, with the other outlet occupied by nothing else. So it is: OUTLET >>> SUPPRESSOR >>> DEVICES (pc, monitor, printer, phone charger, router, sound system + small sub, lamp, paper shredder). The computer and its components are powered by a three year old Corsair TX650, and am right about on the money for wattage requirements as per http://extreme.outervision.com/psucalculatorlite.jsp with I assume to be ~%25 capacitor aging.

Would you recommend:

New PSU? Which? Modular is preferred.

UPS? Which? And, what do you think of this (http://www.amazon.com/CyberPower-CP1500PFCLCD-Sinewave-Compatible-Mini-Tower/dp/B00429N19W)?

Voltage regulator? Which?

And, if any of the above combinations excluding PSU, in which order (starting with the OUTLET)?

Thank you,

PSU should be fine.

You'll probably be fine - the only issue is loss of data and possible OS corruption (requiring startup repair) in the event of a power cut. Hardware damage is unlikely past a surge suppressor.

If you do want a UPS, I'd go with this:
OUTLET > UPS > Essential devices (router, PC, monitor)
AND
OUTLET > SUPPRESSOR > Other devices.

Your currently selected UPS is probably way overkill; you don't need to run a paper shredder in a power cut for example.

Something around ~800VA should be plenty. The PC should have near-perfect power factor, and the screen shouldn't be too bad. Router is negligible power consumption.

I have one of those UPSes (the CP1500PFCLCD), it's the best UPS I've ever owned. Not that it does anything fantastic, but it's survived 4 or 5 years without any issues, and I like that it'll tell you how much power you're drawing. Also the sinewave power means it'll run a PSU with PFC, which yours has(I believe it's one of the cheapest sinewave units on the market.).

I like to have at least 20% headroom in my psu's. But with corsair, if you run over it just means the efficiency will suffer, plus they are likely to just shutdown if they overdraw rather than causing any damage.

As for PSUs, corsair is my favorite brand, pretty much for all wattages. I also like Seasonic for < 600w as they have some nice silent options. Also Enermax is hard to beat at high wattages (> 850). I've had a few bad experiences with silverstone PSUs so I don't recommend them.

I'd recommend leaving your PSU as is.

Thanks Magic for sharing of your first-hand experience. I'll probably be getting the lower 800VA one, and SomeoneSomewhere suggested (and I see they have one around that VA for the same series, so that's great)
