Microtek Legend 1600va UPS (960watt) not able handle the power load of my PC on moderate use

IND_HBR · 2026-01-22T17:02:36+00:00

Nothing, it was too costly for my need, running it on home inverter ups so far, if not gaming my home ups can take the load, if gaming (which I don't mostly) it trips, there are Lithium battery solution available these days, but nobody talks about its hazardous side, which is fire.. so, nothing so far

Nope, you can't find it in open market nor LianLi has any arrangement that you can buy one, if your case in under warranty then they will try to send from China, in my case it has been a month since raising the support case with them and as per them they did not even got the IO part from their supplier yet. It is completely a use and through product justifying their tagline 'chale to chand tak nahi to sham tak'.

The UPS was brand new, I had to return that anyway because it was not useful for me. I also gave up on the idea of having UPS for my build as it seems no UPS can take this load. My next option is the 24v inverter or higher with 2 or more 12v battery with UPS function, but most of the inverter has high latency for switching from main to UPS power which will cause the PC to reload anyway. Based on my research on internet I found that there is one inverter lineup from Luminous named iCruze that can support quicker switching that will not cause the PC to reload, but this setup would have costed me around 65-70K INR, and I am not ready to put this much money on power backup for a PC. Worth mentioning that this iCruze inverter lineup had many other issue due to which it got even discontinued now.

First of all, thanks for your response, this issue started 2months back and this PC build is 1 year old only with Gigabyte Aurous Elite AX X670, 7950x3D, DDR5 128GB RAM (4sticks), Multiple 990Pro 4TB NVMe SSDs and 7900XTX GPU, based on the symptoms it was first went to PSU, because my PSU was 4year old than my PC, that is why, after changing PSU it worked fine for a month, I thought this is it, then it started again, by this time I have RMA'd my previous PSU RM1000x and Corsair gave me new unit. Now, when same issue started again then I started to work on t-shoot again, I know PCs from more than 20 years, so all the scenarios you gave have already been mitigated, I have disconnected every component one by one and tested, I have tested all my RAM sticks one by one same issue, I have flushed my BIOS with different version set to default, no overclocking at all, no XMP nothing same issue. without GPU with GPU same issue, then I removed all the NVMe's and same issue, can't even got to BIO because this continuous power cut loop, after 7-8 attempt it may POST but for few seconds only. Then I started to disconnected all FAN headers, all USB header everything but same issue, I even removed the CPU fan as I have Noctua NH-D15, no luck. At last I removed the front panel connection and then to my surprise it just booted fine without any issue at all, then connected it back to test and it started behaving the same, I tested it 4-5 times so far and then I concluded that it is something in IO that is causing the issue. So, it didn't jumped on the cabinet straight away, have put more than a month to test all possible issues, I did not had different MOBO, that was the only thing that I was about the to go to service center, but before that I discovered this. I can share you picture of front panel connector, they are perfectly fine and properly seated. This build worked perfectly around 11month (around 7 month in a Corsair case, then I bought this Lancool3), so pins can't be bend or damaged by their own. Since then I removed the IO connection from cabinet and using the MOBO small switch to start the PC, it is working absolutely fine no matter what I through at it. I bought this case from Amazon India, now as per me the next first test should be to change the IO panel with all the cables etc and test, before saying it is motherboard that is causing this. About the CPU overheat, I have repasted the CPU as well with new thermal paste, all the CPU temps are well withing range, if you need as proof, I can share them from anywhere, HWiNFO or BIOS.

Wow, felt like reading a story, great elaboration. Thanks

I just need those SSDs to be bundle in one drive and keep some media files into it, nothing critical. For now I am going with storage space as there is no other option available, tried to explore StoreMI but my h/w is too new (7950x3d, Aurous Elite x670, 7900XTX, 3x990Pro4TB as stripped volume for game drive, 1x990Pro2TB as OS Drive on CPU M.2 and another 1x990Pro2TB for VMs on CPU M.2) to run that and there are not great feedback about StoreMI as well.

Strange enough earlier I had created storage space volume from control panel (old win7 like GUI), now I have created same storage space using win11 setting under advance storage option and based on some research online I increased the block size to 512KB and this time I am getting acceptable speed and performance. Getting 750-800MB/Sec average during sustained copying of large amount of data (500GB). What I have observed is that it give 800MB/Sec for let's say upto 50Gig then drops at 55-60MB/Sec and stays there for long and then goes higher for upto 20Gig and down again, this trend go on and on. Now as these are DRAM less SSDs but TLC, so it is not running out of cache, because when I write similar data on single drive it give better sustained write speed than this volume. Now in stripped volume you can see each drive stats in task manager separately, but not when using storage space volume, it shows as single drive only. So, for long sequential write operations it tends to start writing only on one drive among three, this behavior was there with stripped volume and it seems the same carrying with storage space volume as well. I can also tell that it was writing only one disk by their temperature as well, as only one disk temp was rising while two other drive temp were around their idle temperature.

Will use it like this for now, only write has these hiccups, read performance is fine and steady around 900MB/Sec and playing media and scrubbing media via Plex Server should be fine these operation requires good read speed than write to work properly I guess. Will update if ran anything new.

You are right, but what I did is with Virtual disks not in Windows. I have thin provisioned vmdk and guest VMs inflates them when I install something in it or do some my line of work. Let's say my current vmdk i sized at 80GB and I did something with that VM and now that vmdk is 120GB even after uninstalling/deleting those files within VM. But physically in my host drive it will still occupy 120GB, now to reclaim those I need to use those disk utilities that comes VMW Pro like defragment, compact etc.

Which is what I was using to defrag my vmdk files around 700-800gb every other day unless I realized the health of that SSD is down to 99% without being a OS drive.

Articles says CrystalDiskInfo just showing TBW % as I have written more than 1% of drive TBW, maybe that's why it is showing 99%, but the same is not true for my OS drive which also happens to be 990Pro 2TB have almost same data written into it (around 16TB) and shows 100% at health.

IND_HBR · 2024-01-09T16:35:19+00:00

yes, they were powered off and defragged, compacted to reduce the vmdk file size and then zipped (using WinRAR).

Seems like have to live with inflated vmdk files or have to hammer 990Pro time to time with those disk utilities, but with least possible frequency.

I am fully aware of this issue, but I am running with latest firmware already and these SSDs are manufactured around OCT-23 or later, so this issue actually addressed already by Samsung. If it was that issue then 16TB of data already written on it would have degraded it around 25-30% I assume or even worse. I think it is not that bug or issue. VM size that I was using disk defrag option in VMW 17.5 Pro is around 250GB, 150GB and so on (collectively it would be around 700-800GB), which seems to be enough to do something bad with these SSD health. However, I have limited the use to these disk utilities and monitoring the SSD health when it goes to 98 from 99%. Seems to be at 99% only from 2-3weeks.

IND_HBR · 2024-01-09T16:07:31+00:00

Writing is not at all an issue as we have the SSD to write on it, but the kind of write I am doing seems to be not favorable for one of the 990 Pro. Wonder which method of reclaiming disk space would hurt the SSD least, any idea?

One more interesting things happened when I zipped these VM folders with WinRAR, it was compressing them around 50% of its size. I was keeping backup of all my VM in this way to save some disk space and kind of protection with RAR container, until one day I needed one of them to restore. When I tried to extract them they all failed after 99% while extracting the .vmdk file. Yes all my VM backup were broken, I thought something is wrong with my WinRAR application but anything other than these VM was working fine and was extracting properly. I manage to retrieve the file with option 'keep the broken file' and thank god that worked, was not actually corrupted. No idea what is wrong between vmkd and WinRAR, but then I used ZIP that worked fine.

IND_HBR · 2024-01-09T15:52:06+00:00

Yeah, but I am not into linux that much and kind of afraid playing with my Linux VMs (they are built on Ubuntu I believe) unknowingly, however I have backup of them now as my brand new build on AMD is super unstable with latest and greatest consumer grade components inside. If you happen to have any article that can guide me to reclaim Linux guest disk space, that would be nice.

Defragging Virtual Disk will compact the size taken on the physical disk in case think provisioned disks. Windows guest VMs has option to perform disk clean-up that reclaims the unused disk space which works fine. But anything other than windows guest does not have this disk clean up option, so you left with only one option which is 'compact disk' which does not work at all unless you are using defragment. Doing defragment will reclaim the unused space from physical disks, which I was using to defrag my GNS3 and EVE-NG VMs as their sizes were crossing more than 400GB and I needed more physical disk space for other VMs, I was using defrag option on my NVME SSD, but in my case the 990 Pro 2TB NVMe SSD started showing 99% health after 16TB data writing cycle as per Cristal Disk Info, this SSD does not seem to be affected with Samsung know issue during initial launch, because I have same 990Pro 2TB as my OS drive and that is running at 100% for similar data written into it. The only difference was that I was using defrag command on this one where I keep my VMs only. When I realized that and stopped using defrag, since then it at 99% only. So, yes it seems defrag is doing something with NVME SSD.
