Will it explode?

Re: Will it explode?

I bought RM550X which isn't connected yet before reading this thread.
Is it safe to use it in PC with 65W non-overclocked CPU and integrated GPU which means peak load won't exceed 80W?

What CPU? If it is a relatively recent (Pentium 4/ Athlon 64 or newer, i.e. just about anything made in the last 12 years or so), the low(ish) 5V/3.3V combined rating will be a non-issue since newer CPUs draw their power from the 12V rail (which is why most newer PSUs have very robust 12V rails and comparatively weak 5V/3.3V rails).

What CPU?

some new CPU like Intel Kaby Lake/Coffee Lake or AMD Zen APU
Stefan Payne mentioned bad quality/design. What is probability of explosion under low load?

RMx has DC-DC converters so it does mot matter what do you hook to it.

Virtually any PSU will run that, you should be fine. There is nothing inherently wrong with the design of the RM series, but CWT (the OEM of these) is known for shoddy QA. Though with that it doesn't matter what load you put on it, if there is a loose screw rolling around in the case or bad solder connection it will likely either be DOA or fail early in the warranty period (and while RMAs can be a pain, that's what the warranty is for after all), and unlike the cheap off-brand Chinese specials these have enough protection circuitry any damage should be limited to the PSU itself in the event of failure.

RMx is one of the best series on market ATM, what the heck is all this talk about?

That's not neccissarily the problem.
The Problem is more something like a screw comes loos and does its fair share of carnage.

And with every unit that has two 8pin PCIe connectors on one 8pin connector on the PSUside, chance of burning that connectors with higher end cards (or two on one cable) are there.

And as mentioned eariler, shitty build quality can lead to premature failure or other problems.
If your PC sometimes randomly freezes or reboots, you must not forget the PSU.

CWT (the OEM of these) is known for shoddy QA.

Well, no...

CWT is know for doing what YOU want. If yo want high build quality, they will do it. They might charge extra for it, but they will do it.
And THAT seems to be the problem:
Some manufacturers don't want better build quality or pay extra for it...

But you have to have some contacts in the industry to know about this stuff

And that's one of the things that makes CWT one of the desired companys.

Seasonic on the other hand is something some companys don't want to talk about...
They are just the worst of the worst in terms of contract manufacturing...

And that's also the reason some companys won't ever work with Seasonic ever again!!
Even though there was a time where many companys worked with them...

RMx is one of the best series on market ATM, what the heck is all this talk about?

No it's not!
It's more like a glorified mid range unit that's a bit overpriced...

And only server/industrial grade units deserved to be called 'one of the best'. Sadly those things are rather rare these days...

And also RMx lacks a bit of protection depending on the chip used there is no UVP on +12V, OCP isn't there either. That is useful because OCP acts way faster than OPP. So it might be the difference between components bites the dust or not...

Either way, it's NOT "one of the best on the market", it's just another random/standard PSU with some ups and also many downs. Nothing THAT special.
