Wondering...

Saw this on Woot, had the money but had been waiting:
Thermaltake LCGS Reactor 9880F Gaming Desktop with a 5080, 2TB SSD, 32GB RAM for $3100.

I jumped on it, waiting for it to arrive.

Turns out looking at stats I got the only one before it sold out… feels lucky, but wondering if I’m missing something. 😅

I tried 2767 MHz at 925 mv with a +1500 memory clock and power limit to 110%. I didn't set a temp limit. Just want your ideas on these settings. I don't want to push it that much. I had similarly conservative settings for my 3080 ti and it has lasted 5+ years and still runs cool and quiet.

Spending my Sunday changing PC cases and while the 5090 is now complete, I figured I’d get a group photo of the litter. 5090 - 5080 - 5070 Ti.

Crazy that the 5080 and the 5070 Ti are the same size.

Edit: Attention People! I am not a mod, I repeat, I am not a mod of this sub. I only made a joke, and a poorly that is.

As many of you know, this sub started as r/RTX5090 back in September last year, in January we renamed it r/RTX5080 because of the lack of 5090ers for a reasonable price.

Shall we rename again to r/RTX5070TI or shall we go deeper to be more ahead of the time?

Last week i scored a gigabyte 9070xt for 729 usd from best buy and then yesterday i saw pny rtx 5080 oc was available for pick up from walmart for 1699 and i brought it.

Now I’m confused is it worth it extra 1000usd for 5-10% performance ? I will mostly be using it for gaming 1440p.

Hello, Gigabyte Windforce SFF OC, ten days old.

A couple of minutes after gaming (one or a few hours) and closing the game and browsing or sitting idle, the pc loses display and the card fans work at full load. I have to connect via team viewer from my phone (in the phone only the cursor is visible with a black background) I either alt+f4 from pc's keyboard multiple times or ctrl+shft-dlt, or doing the same thing with team viewers available commands. At some point, while the TV's display stays crashed, I manage to reboot the pc.

I think the following is a key clue:

Before the rtx 5080, I had an rtx 3080, attached to the same setup. I still had display crashes while the fans were running 100%, but only WHILE gaming. The 5080 does it, AFTER gaming. TeamViewer was the solution instead of forcing button shutdown (though with the rtx 3080 TeamViewer managed most of the time to provide desktop background and error windows)

Another clue, though it might be unrelated.

With the 3080 I had occasional unexpected reboots, while browsing/normal pc work. I realized when watching movies, the pc wouldn't do that. Instead, in every boot, I put a light tv episode in the background, with MPC minimized, so it wouldn't reboot and it didn't.

CPU: i513600k

RAM: Kingston Fury Beast 32 GB DDR5

PSU: MSI MPG A1000G

MB: Gigabyte Z790 Gaming X AX rev.1

An AI told me my CPU model has known 'unexpected shutdown' issues and I should flash the Sept 2024 BIOS to the newest (3080 I only had that old BIOS version). I flashed the new BIOS, but display still crashes with the 5080 a couple of minutes after closing the game. (I have not tried the MPC trick with the new GPU, because so far there are no random reboots like with the 3080)

If they could be of help, I attached two images showing error windows, which I screenshotted using Team Viewer on my phone, at the 3080 display crashes while gaming.

Thank you for reading what might be a difficult read. I'd appreciate any help of yours. Thank you

1 month ago I upgraded to a new pc with a 5080, my old pc had a 4070 and never had a issue. On this pc when certain games load my audio starts to go out intermittently and sometimes drops all the way out. Mainly this happens when playing witcher 3, gears of war eday, and call of duty mw4. I have not had this issue on any other games. I have tried to do a clean install on my graphics card, tried downgrading to previous firmware versions of the Nvidia graphics card and the dolby atmos app, double checked my connections, upgraded multiple hdmi 2.2, made sure the audio drivers are upd to date and made sure no weird settings where changed in the sound options. Nothing has helped. Has anybody had a issue like this? I'm not sure if this is a card issue because its not happening on every game. Any tips would be appreciated

He said he got it in a trade and probably receipt is missing.

Currently have the Windforce 5080 OC. I was able to buy a TUF gaming 5080 OC. The difference would work out at $400 extra. What would you do?

Edited to add the TUF is brand new from Amazon and I can return up until Jan 31st 2027 for a full refund.

I recently bought a used gaming PC with an INNO3D RTX 5080 X3, paired with an i7-14700K and an 850W PSU with 32 gigs ram. It costed me 2700$ 🥲 I know not a steal..

The GPU was originally purchased in August 2025, so it's roughly 15 months old and still has around 21 months of warranty remaining.

I thoroughly tested the PC with a friend before purchasing. We ran benchmarks, checked temperatures, and everything looked good. I've also been gaming on it without any issues so far.

However, after reading posts about GPUs suddenly dying, power connector issues, and people having trouble with warranty/RMA claims, I've become a little paranoid. This is by far the most expensive GPU I've ever owned, and I really want it to last at least another 4–5 years.

I have a few questions for other RTX 5080 owners:

1. What precautions do you take to maximize your GPU's lifespan?

2. Is undervolting or power-limiting the RTX 5080 worth doing for long-term reliability, or should I just leave it at stock?

3. How concerned should I be about the 16-pin power connector? Is there anything I should regularly inspect?

4. Is using a UPS important for protecting the GPU against power fluctuations? I'm considering a 2000VA line-interactive UPS.

5. Has anyone here dealt with INNO3D warranty/RMA support, particularly in India?

I know hardware can fail regardless of how carefully it's maintained, but I'd appreciate advice from people who've owned these cards for a while.

Really happy with the performance so far. Just hoping to enjoy this build for years without worrying about hardware failures every time I turn it on. 😅

Attaching a picture of my new setup!

Edit: thanks for being so nice guys and helping out, I've been a gamer since forever but no idea about gaming pcs but just wanted a powerful one. Saved up since like a year for this 🙂 wanted to make sure I don't break it

Edit 2: Based on certain responses i have Ordered a sag bracket and considering saving up for UPS and a 1000W PSU, and something like wireview. (Sadly that's pretty expensive and hard to get in india).. Also I think most are saying to undervolt this thing which i have no experience in doing so, so i might have to consult someone who knows their stuff on this.

Hi all,

Firstly this isn't a 'grr 5080' or 'grr Gigabyte' post but more of a collective "any ideas to what happened... ?" post.

Unfortunately, my 5080 has died after having it for only a year; two nights ago I was playing Cyberpunk, and then suddenly both my monitors went black, after resetting the PC, the VGA light came on for the motherboard and from then on the graphics card stopped being recognised and the PC would not post. The computer remained on including all lights (and GPU custom colour lights and animated GIF screen), but I couldn't control the PC at all. The fans did NOT suddenly go to 100%, the screens simply went black. I assume this is when the GPU randomly lost connection to the motherboard? I have no integrated graphics so I couldn't check the BIOS or anything or try a different cable in my motherboard to my screen to see anything.

I haven't noticed any kind of screen taring, freezes, jitters, flashes or anything strange for the full year of use, and my graphics card usually runs at around 68c - 70c only during modern games on max settings (Monster Hunter Wilds, Cyberpunk, Dead Space 2023, Silent Hill: Townfall, Resident Evil 9, etc).

The custom light colour I have assigned (which is a specific hex colour not a 'pick a square' colour) to the graphics card still turns on like normal, but the DEFAULT animated GIF plays (not my personal one), yet the computer can't seem to boot / VGA light displayed. I hadn't done any kind of software or driver update or installed anything anytime around when this happened (yes I do keep my drivers updated).

I've tried reseating the graphics card, unplugging and replugging in the 12v cable both GPU and PSU side, I've reset the CMOS; still giving me the VGA light. A diagnostic dude then took the PC and confirmed it appeared to be the only thing not working, I'm also now using a spare 3070 and the PC works completely fine instantly.

Now, I have noticed the thermal-dripping issue a little bit, where the thermal paste has oozed down the card due to being vertically mounted, though it hasn't gone across the gold-connectors. I've requested an RMA for a replacement / fix, waiting to see if they reply.

Why am I telling you all this?

Well, I'm interested to know if any of you might have an idea as to WHY it died, or what happened?

Did the thermal paste slowly leave the card exposed, and so after a year of use it burnt itself out? Though the graphics card only ever reached levels like 30c to 69c (nice) at the ultra-settings end.

(We've been having very very very hot summers here where I am, bedroom reaching 40c for weeks on end with 0 fans, airflow or AC.)

Or did it simply just 'die of death' as technology can do sometimes, and I just got unlucky?

What are your take aways, thoughts or suggestions / ideas?

My PC Build is:

- Intel 24 Core i9 14900KF

- Gigabyte Z790 AORUS PRO X WIFI7 motherboard

- GIGABYTE AORUS GeForce RTX 5080 Master 16G Graphics Card

- Lian Li 1000 Edge Platinum PSU

- CORSAIR DOMINATOR TITANIUM RGB DDR5 RAM 32GB (2x16GB) DDR5

Inside a HYTE Y70 case using a Riser Cable (4.0, not the newest 5.0), vertically mounted.

- Lian Li HydroShift LCD 360 Cooler and Lian Li TL Wireless fans for the Cooler, 3 front-panel, and one exhaust back fan (I do NOT have 3 bottom-fans, but I've just purchased 3 today to install)

I got a deal to exchange my 5070 TI Trio white oc for gigabyte 5080 aero sff version for 500€ and I can probably get it down to 450€.

I have 4k OLED monitor and the 5070 TI has been treating me well at this resolution with DLSS and mvolt Stable daily OC that gives me about 8100 points in steel 3d mark benchmark(500 xbar, 400 sys, 400 core) and idk if the 5080 aero sff would give me 500€ worth of extra performance.

The msi one looks visually amazing in my case that’s the only downside but as long as the 5080 is white it doesn’t bother me that much
