PC doesnt boot right
Posted by PresidentSkillz@reddit | buildapc | View on Reddit | 6 comments
I bought a prebuilt about a year ago (shame on me, i know), and ever since it had issues when booting up. sometimes the monitor just didnt start, sometimes the headphones had terrible sound (which got worse the longer you left it like that) and only a full restart would solve it. Replugging the monitor made it constantly switch between analog and HDMI for example.
I did a BIOS update yesterday and it kinda made things worse: when i boot it now, none of the periphery works (monitor stays black, RGB on mouse and keyboard doesnt start etc) and again only a full restart solves it. But whereas the first issue only happened sometimes, this one now happens every time i start my pc.
I am kinda new to pc building and still learning (which is why i opted for a prebuilt which i intend to upgrade as times goes on), so Im not sure what causes this. I asked Claude AI and it said its about the power supply to my GPU. I dont want to buy things bc some AI chatbot says thats what i should do, so i need some actual advice here.
I have a Ryzen 7 8700F, an RTX 5070, 32GB RAM, an MSI pro 650-S Board and a be quiet system power 10 750W PSU. The Reliability Monitor doesnt show any errors regarding this issue btw.

My bet is on the PSU.
I had the same model and it would do very weird stuff under load (disconnect/reconnect keyboard/mouse, rgb lights flashing inside pc and loud buzzing noise would come through my headphones). The overload protection clearly didn't work in my case, as it never shut down the pc though. I ended up replacing it and all of these problems were gone.

What would I want in a new PSU? If I have to replace it I want a good replacement

Generally speaking if you follow the tier list and buy an unit that is atleast B-tier, it should be a safe choice. I'd say 750w-850w is plenty as of what comes to wattage requirements. ATX 3.0-ATX 3.1 with native 12V-2x6 cable for your gpu would be the best.

Im seeing some PSUs with cables and some without, i suppose those without have compatible ones included, just not shown in the pictures? Or would I need to buy them extra?

What you are seeing is the difference between modular and a nonmodular unit.
All modular units come with the cables included, but you have to plug them into the PSU yourself. They are generally better for easier cable managment, as you rarely have to use all of the cables.
