Ah, I didn't realize the supplies did not come with the computer; that changes everything. You have certainly come to the right place for advice.

Who is the best of the three compared to the 1st PC for energy quality-efficiency ratio?
If you have enough on one PEG connector in the future then the Corsair CX450 is a good option for 49,90 euros.

If I'm not wrong, are there two platforms of the cx 450, ?
Corsair CX450 CP-9020120-EU and Corsair CX450M CP-9020101-EU
What is the difference between the cx 450 and the cx 450M, apart from the modularity?
However, many people after a while complain that the cx450 / M suffers from whine coil

There are two different versions of the CX450, but it's impossible to know which one you get before opening the box. One is build by CWT and one is from Great Wall, but the performance and quality should be comparable. From outside they also like the same PSU, the only differences are internally.

Then there is also a CX450M, which isn't a modular version of one of those CX450 power supplies, but a totally different one, build by CWT. Quality is a bit worse, mostly because of the fan. But it comes with two PEG connectors which could be a plus. It's also semi modular, but that's not a big plus because of the lack of cables and connectors.

This PSU's aren't known for coil whine issues, still it's always possible to have coil whine, no matter which PSU you buy, everyone can have it.

So the big question is, do you need one or two PEG connectors?

Fan noise?

Yes, the Hong Hua fan in the CX450M is bit know for the lack of quality control. Still the chance is small that you get a bad one, but it looks higher then other similar power supplies.

I need one peg connector, certainly two would be better.
Corsair has been releasing budget power supplies for quite some time now in the CX-series, but the version that we test here is the so-called 2015 Edition, which means that it was revised in that year. The previous 2012 Edition performed rather well at the time, and received a Bronze Award a few years ago. The M in the name stands for Modular, because the power supply is semi-modular (the ATX- and CPU-connectors are fixed).
https://uk.hardware.info/reviews/698...t-power-supply


The CX450M is double forward with DC to DC for the +3.3V and +5V. It is non-modular. It is built by CWT.
The CX450 uses a slightly newer LLC topology. Also with DC to DC. That makes is more efficient across a wider range of loads (although still not quite Silver). But the CX450 is not modular. CX450 can be built by CWT >>or<< Great Wall.

I am undecided between:
Pure power 10 400/M
Seasonic Seasonic Eco 430ST Bronze Retail?
Cx 450m or cx 450
Super Flower Platinum King 80 Plus
