Hey everyone,

I wanted to share an issue I've encountered and see if anyone has experienced something similar or could offer some insights.

So, I recently got my brand new custom gaming PC delivered. I was thrilled to finally get it up and running. For the record, everything was set up properly and the initial tests seemed smooth. However, when I tried running the Robocop Demo, things took an unexpected turn.

Every time I launch the game, it goes through the intro screens with stuttering. But as soon as the intro screens finish and it looks like it's about to load the main game, my entire PC shuts down abruptly. No error message, no warning – it just powers off.

Here are some quick specs of my PC:

  • Processor: AMD Ryzen 7 7700
  • Graphics Card: NVidia RTX 3060 Zotac
  • RAM: Corsair Vengeance EXPO 32GB (2X16GB) DDR5
    PC5-41600C40 5200MHz Dual Channel Kit
  • Storage: WD Black SN770 2TB SSD M.2 2280 NVME PCI-E Gen4
    Solid State Drive
  • PSU: be quiet Pure Power 12 M 750W ATX 3.0 80 Plus Gold
    Power Supply
  • Cooling System: be quiet Shadow Rock 3 White CPU Cooler - 120mm
  • Operating System: Win 11 Pro
I've made sure all my drivers are up-to-date, checked the game's compatibility, and also ensured my system isn't overheating.

Has anyone else encountered a similar problem, specifically with the Robocop Demo? Or can anyone pinpoint what might be causing this? Any help or guidance would be greatly appreciated!

Thanks in advance for your time!


Edit I tried Quake 2 RTX and I can navigate the main menu fine but when I start a new game it just shuts down completely as well.

Removing the GPU and relying on the onboard graphics might indicate it's the GPU but it could still be the PSU as by swapping to the onboard you're reducing the power under load by potentially a 100+ watts (I can't remember what the 360 draws).

Having said that, I think it's a good bet it's the GPU as that PSU is quite a high output model so should have plenty of headroom unless there is a fault that is only affecting the power via the GPU cable.

That was the case. PSU was the issue I decided to salvage my Corsair 850W to see if it fixes the problem. It did and my PC is working great. I’m in the middle of arranging a replacement PSU as it’s defective. Even tried using it on my old machine and it doesn’t work either.
 
That's good new that you've isolated the problem and hopefully got it sorted :)

One of the reasons I keep a stack of old hardware is for troubleshooting like this. Not that I'm a bit of a hoarder who keeps forgetting to clear out the garage, honest ;)

Yes. Im now using a :

Corsair RM Series™ RM850 — 850 Watt 80 PLUS® Gold​

From 2015. But really PSUs hardly change over time due to the nature of power supplies.
 
750w should be more than enough for that system, you'd think they test those things under full load before leaving the factory. Probably something wrong with the 12v rail

Ah yes, that old chestnut. I’ve told myself that on countless occasions as I stare into a box or drawer full of pc bits I don’t ever remember acquiring. :p

The PC was on assembly to delivery for 17 working days. Demanding period and they hired new staff. Wasn’t particularly happy with the GPU power lead connected as there wasn’t any slack on it and been stretched as far as it can go. Plus the motherboard ATX 24 pin was missing a pin on the 750W while the 850W had all pins.

I was told OC had new hires. Normally a red flag in my eyes as they won’t be competent to OCs standards. Not assemblers fault. People make mistakes but the new hires should be supervised for this very reason.

Good news got my DPD sticker for the PSU return and I’ll get a partial refund on the custom build for the PSU.

would have probably saved myself the hassle and assembled it myself but I’ve not built a PC since 2007 and that was in college.

My friend who helped me figure out the issue ended up giving myself confidence to build my own in the future.
