Black list of power supplies and reputable brands of power supplies

>>21594332 I have not been able to find a blacklist of UPSs on websites, but AI from google.co.uk suggests one: Acutake , Akyga , Allied , Altis , Bandit Power , Coolmax , Deer , Diablotek , Foxtech , iCute , Lepa , Linkworld .
So Gembird can be bought without risk....

Separated from the thread about blacklisting computer power supplies, as the topic has expanded a bit and turned to shopping.

It's not worth trusting everything AI spits out. Some of these companies don't even make UPS. On top of that, the alphabet ended at L in AI, so the list is not complete (although G would already be on it).

Is there any reason why you want to become a tester of such a device when you can buy something from a brand that specialises in power supply equipment for probably similar money?

>>21594335 I don't want to be a tester, but a user. I want to buy a UPS that has good performance at a reasonable price and in the filtering results Gembird appears on several positions.

You're better off with a used one from a reputable brand, or, if you like to play around, buy a defective one for £40 and replace the battery. But it's a lottery. UPS and PSU are completely different devices, but if you have a company whose equipment is, ahem, of questionable quality then I don't know if I'd dare connect my equipment to that.

There was a period that I used to make things this way (when batteries were normally taken at the buybacks, because now it's hard), on average 2 out of 10 devices were damaged, the rest just the battery to be replaced.

>>21594491 So the Gembird brand you don't recommend? And which ones do you think are worthy of consideration?

A little off the main topic but ...
This is where the fun begins . Because everyone has different ideas about the word "good".
First and foremost: what (what device) is this UPS supposed to protect?
Do you want a full sine wave or is a rectangle enough?, possibly some anti-spike filters, a surge protector on the telephone network. Is it to be managed (with USB)? and how is it to be managed (I can't remember the name now, but I would shoot the developers of the software for one UPS - I have one on "scrap" somewhere), How many sockets, whether "full" 230V sockets or just under cable "plugs", with a display (just what for) etc.?

And recently - which can be both a plus and a minus - I have noticed at work, compared to the old APC UPSs, that in the "new" UPSs, including this particular Gembird-Energene ("650AV UPS WITH AVR"), with a faulty internal battery the UPS will not switch on, that is, it will not even let through the correct voltage from the mains - even though it is OK in the socket. It is necessary to replace the battery with a new/working one and at least "residually" charged. Then everything will run as it should. My old APCs even without a battery, but with the correct voltage, "run" through the sockets. Well, and this is where the "plus" of the new UPSs is that you know when you should definitely replace the battery.

In my opinion, for an ordinary PC (with a reasonably good power supply) there is no need to spend a lot more on a "reputable" brand. The important thing is that during a power failure it should hold for "a few minutes" until you switch off the hardware. What is different is the protection of the server. Here, how you manage shutdown etc. is very important.

@iagre Definitely APC, possibly EVER.

First of all, tell us what you need. Wattage, type of enclosure, battery capacity - without this nothing will come up. I can recommend you, for example, an Orvali 10kVA with the current state of knowledge.

>>21594524 Sinus is not needed. The main application is to keep several computers and peripherals running. High power and long runtime at high load are expected and, of course, protection against overvoltage or other network faults and control of the charge and technical status via USB or LAN and all this in a preferred budget not exceeding £1000.

P. S.: And also that this UPS is not blacklisted as a UPS.

Well, count on adding another zero to that amount. And if you have APFC in these computers - then yes, a sine wave is needed.

>>21595424 This is a secondary matter. This post is primarily about creating a complete Black List of UPSs .

There is too much of it. The original title list is also way out of date, as even reputable manufacturers can release crap. "PSU tier list" search, there will be a sheet in google docs. For UPS I haven't seen such a thing, and here I'm afraid it would be simpler to go the other way and make a whitelist.

>>21595724 If it's simpler that way, I'd like to ask experts on the subject to give their opinion on the following brands - black list (reasons), white list (advantages), average.
APC .
ARMAC .
CYBERPOWER
DIGITUS .
Eaton
ENERGENIE .
EVER .
EVEREST .
GEMBIRD .
GEMBRID .
GREENCELL .
Legrand .
NEWELL .
Orvaldi .
POWERWALKER
QOLTEC .
SVEN .
VOLT .
