Issues with Game crashes and sudden system stops have occurred while playing since the PC was built two weeks ago!
Yeah I just ran two passes of memtest and saw no errors. Honestly, I’m starting to give up. I’m not a tech expert and don’t have the skills to figure out what’s wrong. I feel like I should return everything and say goodbye to my PCs. There are too many confusing factors and I don’t have replacement parts to test things out. I’m not sure if it’s hardware or software. It’s all just nonsense and I shouldn’t have to carry this weight after spending around £1400.
It's a hardware issue because you've already excluded software causes.
Now, the information you provided points out two main concerns:
* excessively high CPU temperatures
* weak power supply unit
As mentioned earlier, frequent reboots or shutdowns are usually due to either high thermal stress (which your CPU has difficulty handling) or an inadequate PSU (the one supplying power).
Have you increased the CPU and case fans to their maximum settings to check if the CPU stays below 95°C during Cinebench?
Alternatively, switching to a new, reliable PSU could help eliminate the problem. Even if the issue persists, at least you addressed the PSU upgrade.
Operating a PC sub-optimally and ignoring it can lead to various complications. The same applies to poor component choices, especially the PSU.
Regarding price, I don’t have strong opinions. For example, my main build (Skylake) cost around €4705.67 (or £4013.47) and has been running smoothly for nine years, thanks to my diligent maintenance.
Think of it this way: if you build a house and cut costs on the foundation, then no matter how luxurious the villa or castle you construct above it, once the foundation fails and the structure begins to shift, everything will be affected. The same principle applies to PCs—especially the PSU.
As I’ve said before, and I’ll emphasize again: since the PSU powers all components, it is the most critical part inside the PC.
For me, the build cost—whether €500 or €50,000—is irrelevant. No PC should ever suffer from a weak power supply.
The requirements seem quite demanding. Unless you opt for an SFX PSU instead of an ATX PSU. Among the few ATX PSUs that fit (140mm), Seasonic Focus GX-1000 ATX 3.1 is available, with detailed specs here: https://seasonic.com/focus-gx-atx-3/. Another option is Super Flower Leadex V Pro Gold, an ATX 1kW unit, specifications can be found at https://www.super-flower.com.tw/en/produ...o-1000w-bk. An egg link points to a Thermaltake model (N82E16817151270) and another to a Newegg listing. There are limited alternatives, with some unavailable or lacking quality verification. The two suggested models are reliable choices, especially since Seasonic is preferable for ATX 3.x systems. The Super Flower unit is compatible with ATX 2.x systems. If flexibility is needed, consider relaxing the length or power requirements.
Honestly, I was thinking of ordering a new PSU, but the one I have is rated B+ anyway—plus there’s a comment saying its performance is generally good. That makes me wonder why you think I’m likely having issues, since your own source says it’s perfectly okay for a mid-range PC.
Which list?
I connected two reviews and noticed there isn’t a PSU tier list in either of them.
The conclusion from the TH review indicates that "decent" and "good" have entirely different meanings.
To me, "decent" refers to mediocre, not excellent. And for a PSU with average quality, it would be adequate for an office PC without a dedicated GPU, but insufficient for any setup with a dedicated GPU. For builds featuring a dedicated GPU, a good-quality PSU is necessary, while a superior one is preferred mainly because of the increased power draw from the GPU.
However, if you think that most of the time your build functions well and the PSU operates smoothly (except for occasional shutdowns or restarts), it’s reasonable to label your PC as "midrange".
Certainly, calling it a mid-range build is too general.
I would rate your system as high-end overall.
The CPU fits within the mid-range range for the Ryzen 7000 series, but the GPU exceeds that, delivering strong performance—often reaching 60+ FPS at 4K resolution.
If the GPU could handle 60+ FPS in 2K but not 4K, it would be considered high-end. And if it manages 60+ FPS on 1080p without issues, it leans toward high-end.
Therefore, pairing a mid-range CPU with a top-tier GPU results in a high-end configuration.
The Gigabyte UD750GM offers both positive and negative aspects; it falls into the average category. If there are more drawbacks than benefits (including price), it would be a poor choice, and vice versa.
Personally, I wouldn’t recommend it. It’s suitable for an office PC with minimal demands and where PSU noise isn’t a concern. But for gaming at home, where durability and quiet operation matter, I’d opt for a more robust and silent PSU.
Different people have varying expectations—some aim for higher standards, others for lower ones—and it’s up to each individual to decide what acceptable build quality looks like for them.
Because I’m very concerned about my PCs, I wouldn’t install a unit that doesn’t meet the ATX PSU requirements set by all manufacturers, ensuring safety and preventing damage to other components. In reality, I’ve gone above and beyond with PSUs in my systems.
Some might say I’m extreme, but I paid €206.80 for a high-quality PSU (Seasonic SSR-650TD) for my Skylake build, while my most recent upgrade for a Haswell model was €205.50 (Seasonic SSR-650TR). A better option would have been a decent PSU costing €80.50 (Seasonic GX-550), but I chose the more expensive one to avoid potential issues.
While that’s possible, I feel confident my two main PCs are powered by Seasonic products that meet standards. Only for my third system, an older AMD build, did I lower my PSU expectations and opted for a decent model (Seasonic PX-550) costing €101.50.
Ultimately, it’s your decision.
If you refuse to consider a second, reliable, high-quality PSU—you’re making the choice yourself.
It’s undeniable: unless you test with a second unit known to work, you can’t rule out a PSU problem.
