PSU replacement ?
PSU replacement ?
I need assistance with swapping out my current PSU. It’s a Seasonic S12620ii, and it doesn’t seem suitable for any build after Intel’s Haswell, according to several articles and discussions I’ve seen.
I’m a bit let down because it cost me around 80€ four years ago and was once considered one of the best PSUs on the market for that price.
My current PC setup includes:
- TUF B660M PLUS D4
- i5 12400F
- ARCTIC 34 eSPORTS DUO
- 32GB G.Skill Ripjaws
- GTX 1650 super (to be replaced soon)
- KC3000 1TB
What PSU should I consider purchasing for a budget of roughly 60 to 70€? I’m based in Serbia, and I found several websites with many options listed. They are:
itsvet and eponuda.
Looking ahead, I plan upgrades such as a 2k monitor and a more powerful GPU, plus a better CPU. Therefore, I require a reliable PSU that can handle all these future changes. This is the most important upgrade for me—I won’t be using the S12 v2 again. I think a tier C unit would suffice, but if a higher-quality option fits the same price range, I’ll go for it.
I’ve noticed that good choices within that budget include models from MSI MAG BN series, Corsair CV, Cooler Master White MWE, and others.
Apologies if my English isn’t clear. Thanks!
Expand your budget further, the PSU is the most important component, so it's wise to invest in a quality one, especially since you're planning an upgrade. Any high-end option would be ideal.

Will this fit better? The price reference is 1€ = 117din.
Cooler Master MWE v2 appears as tier B in the list, but I’m unsure if it’s actually that PSU and whether it truly matches tier B. There are often incorrect details shown. In the list it’s labeled MPE-ACAAW, here it’s MPE-6501-ACABW-EU.
I’m not sure if it’s the same unit. If it really is tier B, it could be a good choice, but the warranty is only three years, so I’m skeptical it’s MWE v2. It might actually fit in tier C instead.
Welcome to the forums! Your English is fine, no problem.
The models you mentioned are generally average quality, not terrible but also not outstanding. I wouldn't choose any of them.
EDIT: I meant these options:
I discovered that for a price range suitable, good choices include MSI MAG BN series, Corsair CV, Cooler Master White MWE, and similar models...
If you decide on the CPU and GPU, we can offer more tailored advice since we understand your system requirements better.
If you ask me, no one should cut corners on the PSU—otherwise you risk falling short of a solid Tier B setup.
I think (without knowing your exact CPU and GPU) a 750W unit would suffice. It would be even better if we could confirm the specific components you plan to purchase later, especially the GPU.
SeaSonic Focus series and Corsair RMx and RMi are solid options.
Usually, most of those power supplies are available in North America and other regions with standard 110-120 volt outlets. This model only supports 220-240v. These versions tend to be more efficient and help reduce the need for components that aren't required for handling 100-240 volt ranges.
It remains part of the MWE v2 White branding, though minor updates can be hard to recall.

For the GPU upgrade I considered options like RX6700 and RTX4070, but they remain quite costly here. They support the new ATX 3.0 connectors. I need something capable of running games at 2k 75Hz without too much detail. My old 1650 can handle older titles, though its VRAM is limited—I think that’s a big issue. For the CPU, a non-K i7 seems likely given my B660 board, but it might be delayed.
Right now, I don’t have the budget for all of this. I lost my job recently.
The PSU is now more important than the GPU or CPU after some time.
I just hope this Seasonic didn’t cause any major damage to the motherboard yet.
No issue at all. With a 4070/6700 and an i7, a solid 750W would definitely help and might even last longer with this upgrade and possibly beyond. Since top models come with a 10-year warranty, the manufacturer is confident it will hold up for at least a decade.
Hope everything proceeds smoothly and remember, as others mentioned, investing in a better PSU is worthwhile. It’s better to wait and get something more reliable.
I don’t believe the SeaSonic caused any damage. What makes you think so? Have you noticed any system crashes during heavy use or sudden restarts? Or are you just curious?
I haven't had crashes recently. I played some older games and mostly just browsed the web. Even before that, with demanding titles like GTA 5 and Far Cry 5, everything worked smoothly. I only experienced issues with XPM, where games would crash to the desktop. Lowering the frequency from 3600 to 3400 helped resolve it. I believe the memory controller in this CPU is limited because it's a non-K model.
I was concerned about the PSU since it's listed as tier E-avoid on a cultist site, and I read that group regulations could cause problems, potentially damaging the motherboard, GPU, or affecting performance under high or low power conditions. This information came up in forums, Reddit, and even Windows Copilot warned against using this PSU.
Earlier, my old system with this PSU (Gigabyte B85M-D3H and i5 4th gen) had frequent cold boots and would restart when shut down. I thought the PSU might be the issue, but after switching to a new PC and Seasonic, there were no problems. In the past, my old PC would shut down properly with this setup.
I bought a cheaper PSU (LC Power LC600H) and moved Seasonic into a new build. It only had an i5 4460, an integrated GPU, one SSD, and was used mainly for browsing by my parents. I didn’t want to spend more on it. Now, with the LC PSU, the old PC shuts down correctly again.
Maybe this was a motherboard-related issue, which is unusual. To my parents, it only causes restarts—not major problems.
If this Seasonic doesn’t affect the VRMs, GPU, or CPU, and I stick with this setup, I think I should go with your advice and save money for a better unit later.
You shouldn't opt for a C-tier CPU or GPU, nor should you choose a C-tier power supply unit.
It's hard to ignore the expense when finances are limited, yet a PSU tends to be one of the pricier parts. If you cut corners on the graphics card, the performance gap becomes obvious immediately. Similarly, a low-cost monitor will reveal the shortcomings quickly. With an inadequate PSU, problems will surface unexpectedly. Hopefully, it will still function.
Here are some budget-friendly options:
- SeaSonic G12 GM 650 – decent for a lower budget: [link](https://www.eponuda.com/kompjuteri-...50...na-9210835)
- Fractal Design Ion Gold 750 – a noticeable improvement: [link](https://www.eponuda.com/kompjuteri-...an...ena-938500)
- A 550w model is more affordable and still close to your budget: [link](https://www.eponuda.com/kompjuteri-...an...ena-938494)
- A 650w version is also available, all with similar performance and a 7-year warranty.
If the Ion Gold 750 isn't within your reach, consider Pure Power 11 600 – it's a solid alternative: [link](https://www.eponuda.com/kompjuteri-...du...ena-543258)
PSU prices are rising. With the Ion Gold 750, you'll be protected for another seven years. Although it's not an ATX 3.0 model, this is fine since ATX 3.1 will arrive soon and all older 3.0 units are beyond your budget. You might find a reasonably priced GPU that fits within the 750w power limit in the future. Switching to a 13600/14600 won't drastically increase your power needs.
A good GPU usually requires a solid PSU, so consider increasing your budget to around 90 euros. A 70 euro unit won't guarantee reliability. Even less dependable PSUs are becoming more costly, especially in Europe.
