Question I accidentally bought an "avoid tier" or "not recommended tier" PSU from tier list on the internet --- should I be worried ?

[BlazeZ__]

Hello, I bought a new pc almost year ago, Recently i have noticed that my PSU is way down in "avoid" or "not recommended" PSU tier list, but at that time i didn't know things very well.

It is working fine for now but is it ok to keep using it or buy a higher tier psu like Msi Mpg Gf. Should i be worried? Does the psu tier list on internet matter?

My specs

Psu - Antec Csk 750 Watt

Cpu - 12600K

Gpu - Msi gaming X Rtx 3060

Ram - 16 x 2

Motherboard - Msi pro Z690

Please guide thanks

It's not the absolute worst PSU. But, I'd at least replace it before the 3 year warranty is up on it. From what I can tell, PSUs are up in price right now. Maybe plan to replace it during the upcoming year when you can find a good PSU for a good price.

Yes, it's bad. Yes, you should return it. There's worse junk out there, but this is a new system and you should not have a group-regulated PSU designed to run entry-level rigs from 2005 in there.

And no, you don't actually know if it's working effectively. Like eating a pound of bacon for breakfast every morning, it can be a long time before you see consequences. Any time this rig is at load -- and modern CPUs and GPUs are designed to basically overclock themselves to their limits -- you're almost certainly going to see some ugly crossload voltage regulation.

There's you're almost certainly going to see some ugly crossload voltage regulation.

Whats that could you explain a little bit Thanks


Ps- its 10 months old now i dont think i can return it.

Group-regulated PSUs regulate the +12V and +5V rails together. But in a modern system (anything with a GPU since 1999), there's very little +5V power used a a lot of +12V power used. With a ton of load on one rail and almost nothing on the other, group-regulation struggles to keep both well-regulated. And since group-regulation is the hallmark of a cheap PSU, you almost invariably see cost-cutting pretty much everywhere else; poorly configured protections, cheap capacitors, little ripple mitigation, etc.

Returnable or not, this PSU should not be used on a modern gaming PC. This is safety equipment; if you want to maximize the chances of the components of your PC having a long, healthy life, you ought to take this very seriously.

The PSU is the one thing you should never skimp on. A bad PSU can literally set your PC on fire. Yes, this has happened to me before. Fortunately, only the PSU burned down, but I had to air my room for several hours to get rid of all the smoke. I didn't notice the smoke until my PC simply shut down and black smoke escape from it. If the PSU had kept burning, I could've choked to death.

It's the reason why I no longer buy pre-built PCs, as they all ship with cheap, low-quality PSUs (and mainboards) to keep the costs down.
Honestly, your PC's safety is the least of your worries. Your house and your life are way more valuable.

Yes, I think the Antec should be replaced.
It is probably not dangerous.
On occasion, 3000 series cards can have unusually high voltage spikes that your psu may not be able to handle.
The msi unit as a 850w unit and a 10 year warranty would give you peace of mind.
