UPS questions

[AsRock]

Thank you very much for the insight. I'll check out some 1500va UPSs like the one you linked! $200-300 is worth it to help protect my investment.

Would something like This guy get the job done?

Yes it should be ok, and as Bill said the Cyberpower ones are good too, both done there job perfectly fine over 20 years now.

I had a Cyberpower unit fail once and it did it's job still no warm done to any thing connected and that unit had been in use over 8 years.

Well, that will depend on what OP is doing at the time of the power cutoff. A 1500 VA UPS should indeed have about 2-3 mins of runtime with that PC under full load (my rough estimates). I guess that works

As long as it gives you time to shutdown correctly it be perfectly fine.

@kDude
after an oversized Corsair psu 750w died within 2y (simulated sine out), i decided to spend a little more, and only get pure sine out,
given that going cheap usually doesnt pay off on the long run.

and the fact is, since then no other psu under same use/location (even those i stressed to max output) has died within 5y.
if that means spending another ~50, so be it, spend a lot more on other hw, so not sure why i would even be interested in a simulated sine out unit,
unless it powers peri/network/moni.

I used my CORSAIR RM750 only on the wall socket here with 230V AC and 50Hz. That psu died after 18 months. Lot's of discussion to get 95% refunded from the seller amazon.de.

Corsair PSU are trash in my personal experience. Random issues. Bought an enermax revolution D.F. 750W psu and all problems were gone. My hardware may have used up to max 350Watts. Still issues while idle with active screen and Radeon 6600XT / 5800X / Msi B550 Gaming edge wifi / Crucial P5 plus 1TB nvme

Note: First buyer of that psu, cpu, mainboard, graphic card, nvme, pc case. Everything assembled with esd groud plug and esd wrist strap. No official used parts which I was made aware of before buying.

personal experience with a single unit?
lol.

LOL You mean just exactly like the "single unit" anecdotal experience you just posted about?

You had "one" Corsair 750W PSU die after ~2 years. You buy a pure sinewave UPS and have not had any PSUs die since so you conclude from that (1) your original UPS killed your first PSU, (2) it couldn't possibly have been a faulty Corsair PSU, and (3) your later PSUs still work because they are on a pure sinewave UPS. Come on, Waldorf! That's just silly - even for you.

Simulated sinewave output does NOT automatically suggest "cheap". That's just FUD. Cheap is a factor of design, choice of components, and manufacturing techniques and finally price. The exact same factors that apply to all UPS regardless if on-line, double-conversion, or off-line, or the type waveform it outputs.

Exactly like power supplies and pure sinewave UPS, there are "good" and poor (cheap) simulated sinewave UPS and in all cases, the cheap ones should be avoided - at least when used with sensitive electronics like computers and expensive home theater systems. NOBODY is suggesting anyone go out and buy a cheap UPS.

But don't take my word (or Waldorf's either) on it. I already posted links to EVGA and Seasonic, two of leading PSU makers, and one to Eaton (a if not the leading UPS maker) who all note that modified (stepped, simulated, approximated - whatever you want to call it) waveform output UPS are just fine with their PSUs and computers.

Don't fall for the marketing hype or those who already did. The ONLY reason pure sinewave UPS have gotten so much attention in the last few years is because their prices have finally dropped enough to become competitive AND the marketing weenies of the manufacturers of those products are trying to convince everyone they need a pure sinewave UPS. That is simply, pure marketing hogwash.

I agree that we "need" a "good" UPS with AVR on our computers. But it does not "need" to be pure sinewave. If you believe the hype, go argue with EVGA, Seasonic and Eaton.

Once again, I am not saying to avoid pure sinewave UPS. If you can find one at a competitive price within your budget that meets your power requirements, go for it. But do not fall for the hype and dismiss a "good" modified waveform UPS just because it is not a pure sinewave.

Remember, the waveform type only matters when the UPS is supplying backup power during a full power outage. For the vast majority of users, that is a few scant minutes out of months and months of constant grid service.

Active PFC PSUs have been around for years and have been supported by modified waveform UPS just as long with no problems. There is absolutely no technical reason, all of a sudden, these UPS are no good and a pure sinewave UPS is suddenly now "needed".

Waldorf.

No offense. But do you know me? Or what I do? When you would read more in this forum or what I post in past hours you would have seen my post in the mainboard topic. (just don't assume anything - got it!)

My sample size is much bigger as my own room / just my own single desk computer.

At work a Fractal Design ION 550W died also. Was a *** custom build computer for one of the employees in *** in homeoffice in a remote location.

I also repair stuff for others and myself. Paid repairs.

and?
the same way me not recommending GB based on past experience/reviews etc still has no bearing on its actual quality.
so unless you have the same unit +2000 times having issues (so it becomes statistically relevant), its only an educated guess.

especially considering no detailed info (e.g. always out of (atx) spec) or even talking about which units are trash, as corsair (like many others) doesnt make their own units,
and uses different makers with some being well known for good psu stuff.

would have taken <1min of typing to add details/contex to make it believable.
