its like they want people to be confused

people don't want to by expensive stuff. like RM1000e is 14k and RM1000X is 16.5 for new version. 14.5 for old stock. But RMe is 7 years warranty, RMx is 10 Years. people will want to save money and get RMe. so people got corsair product for low and corsair sold more products then that of competitor.
Unless people condition or mentatility don't changes, companies marketing team will F our minds for sure.

my new rm650 has a 16A plug(power plug?), the problem is i dont have the compatible big outlet in my room right now.
should i try to turn it on using the cv450`s plug?
havent tried turning on yet due to incompatibility and the fear of everything burning down.
attaching photos for reference.
would really appreciate it if someone can reply asap, thanks.

smaller one is from cv450 and rated at 13A, while the bigger one is rated at 16a and from rm650.
EDIT- Nevermind found an old adapter.

idk if this is the right thread to ask this but what ups would suffice for 550w psu?

I have a luminous inverter at home which has an option of UPS on it, is it relevant to my use?

The UPS option does nothing but reduces the operating range of the inverter to like 200-280V and in non-UPS mode it's like 180-300V.
What this means is that when the mains power is between that range the inverter will not be switching to battery but as soon as it's outside that range the inverter will switch to battery mode.

You need to put your PC on full load (stress GPU + CPU) and simulate a power cut but turning off the mains MCB to test if the inverter is fast enough to switch to battery before the PC shuts off.
If your PC stays on then you don't need a UPS else you need one.

For your needs an APC 1100VA Back-UPS should suffice.

Would UPS models that hook up to external batteries be a much better option to the regular ups models that come with tiny batteries? I'm specifically talking about the microtek and APC line-interractive units that do not come with batteries attached. Something like a "UPS OFFLINE DESIRE PRO+ 2000" from microtek.

They would offer much longer runtime (based on the batteries you buy) and wouldn't need to be setup near the PC. Not having to hear that fan noise would be great after using a regular ups for years.

Another option that I was considering is a standard inverter that has a UPS mode. Both luminos and microtek seem to claim <15ms switchover time and the PSUs that I'm considering for my upcoming build have a hold up time of 17-18ms (based on tests done by cybenetics).
Would this mean the inverter can switch over fast enough to act as a ups? Can the switchover time be longer than 15ms in various circumstances?

Also I'm still confused on the benefits of pure-sine wave vs stepped approx/simulated sine wave. My current ups and pretty much all affordable ups use a non-pure sine wave, but most inverters use pure sine wave. So assuming the holdup time is fine, would an inverter be the better option or do the line-interractive UPS' offer other essential features that PCs specifically need?

In the same boat exactly now. I'm trying to find used 2kva online ups

Regular inverter in UPS mode works fine for me and has been for the past 10 years. I have my complete home except power points connected to it and I don’t even know that power has gone out. The switching is that fast. My PC, TV, projector etc everything remains on.
Don’t even consider non sine wave inverters. They are not good for anything containing an inductor such as a fan or audio equipment containing transformers.

Which model u use.

Sukam 1400va sine wave inverter. I don’t think that this company exists anymore.

I am pretty sure that modern sine wave inverters would have a better switchover time.

What PSU does your pc have? Also do you know if running it in ups mode wears out the batteries quicker?

I had a 750w cheap psu and now a xpg more expensive 650w and they both worked fine. I don’t think it affects the battery lifetime if you run the inverter in UPS mode. The only drawback is the input voltage range is lower than in inverter mode. But, I think its an advantage as large deviations from 230V are not allowed and the inverter switched over to batteries even if the power is on but out of spec.

The inverter will go into battery mode more often in UPS mode if there are frequent out of spec voltage conditions thus wearing the battery out.

I think but don't know exactly, inverters mostly have 12-20 ms of switchover timer....some have faster nd some slower. At same time psu ought to have 16ms or higher hold down time as per specs....but most are below that.
I may be wrong on inverter part as haven't researched much.
 
I have a 4 year old Luminous Zelio+ 900 VA pure sinewave inverter in UPS mode. I can confirm that my PC never turns off during a power cut. This is true for both my old build using a Seasonic 520W PSU and my new one with a MSI 750GL PSU.

I'm talking about the case when the PC is in normal use. I haven't fully tested the case where you're gaming at full tilt and the power turns off. It was never a problem with my old build, but the new one is probably closer to the edge with an RTX 3080 pulling 300W on its own, lol. Especially if there are any other loads active in my house at the same time.

If you get an inverter, I definitely recommend getting a higher VA than mine.

hi, i have been searching from past 3 months now and have found no option on what to do, help would be really really appreciate, here are my specs

ryzen 5 7600x
rtx 4070 super oc
32gb ddr5 ram 16x2
8tb of storage
1440p monitor and an
MSI MAG A750GL 750w 80+ gold psu



now i live in a relatively small town, so i am not really sure about how the grid is around these parts, what i am sure about is that i dont my really expensive system to blow up XD

heres a bit of context :-

1. i am not sure if my house has any thing to protect against lightning or anything, my house does have a solar system (ongrid) which has a lightning arrester, where a really long copper pipe is on my terrace and that is grounded, my home additionally is also grounded but i haven't seen any copper pipes on my terrace for that, additionally we do have something called instaTrip idk what that is

2. i am a bit tight on the budget, around 20k max including getting everything

what i want to do :- i want to know things that i will need to 99.99% safeguard all of my electrical equipment + get some sort of battery back-up for my pc and some fans and lights with some plugs to charge my devices

now coming to the main question, what do i do ? do i buy a ups, if yes ? then which ups, i dont wanna wanna spend like 15k for just a ups, would it be more advisable to get myself an inverter system with additional fail safes like house stabilizer + surge arrester and whatever else i could need, please, help would be really appreciated
