[SOLVED] Which PSU should I buy?

[TantuFaz]

Can't find a good durable PSU here in Brazil. Some products here seem to be old version.

Spec:
Ryzen 5600G
B450M Steel Legends
2x8GB
HD 512GB 7200RPM
SSD SATA 240GB

Maybe will buy GPU in future(if good price) with low wattage.

Country: Brazil
Budget: R$350 BRL($60 USD)

Fonte = PSU

Thinkin about:

"Fonte Cooler Master MWE V2, 550W, 80 Plus Bronze - MPE-5501-ACAAB" for R$319,00($57) in Kabum.

"Fonte Cooler Master 550W 80 Plus Bronze Semi-Modular MasterWatt - MPX-5501-AMAAB" for R$349,00($62) in Kabum.

Reason: 5y warranty and the second one is semi-modular.

I was thinking about this Brazilian PSU, but seems to be bad. I don't known how certifications works, but some consumers bad review in YouTube and only 1y warranty make me think that they just make one good PSU to be certificated.

The Cooler Master MWE Bronze V2 is a good unit.

The Cooler Master MWE Bronze V2 is a good unit.

"Cooler Master MWE V2 White and Bronze units have high ripple issues on very low load also resulting in increased coil whine, fix pending." - Note in PSU Tier List.
Isn't that a bad thing, since my computer will be running in low load?

Right. It's because of the burst mode. Cooler Master thought they could just swap out a standard LLC controller for an LLC+burst without making other changes and the low load results are not so good.

This is an old double forward PSU. Even worse.

And this one is complete garbage fire hazard double forward group regulated.

So out of the three, the MWE V2 is still the best choice.

There is no better Power Supply in this budget here in Brazil?

It's called needing to increase your budget.

If all I could buy to drive myself to work was a Chevy Spark or Hyundai Accent, I would take the train until I could save up more money.

What certifications exactly? There are a lot of certifications. Efficiency is not overall quality. Nor are noise and heat level.

It's junk. I'd rather hook a PC to a salami sandwich. At least then the PC won't turn on, keeping my components safe. Then I can get lunch.

Like has been said, you would need to increase your budget if you want a PSU that is excellent across the board. Any budget PSU is going to have some negative aspects to it's performance. But you don't really need a PSU that is excellent across the board for your system.

The burst mode of the V2 that causes the ripple does have the benefit of increased low load efficiency, which is why it's implemented, so there's that. Overall it's a fairly good PSU aside from that though, and I think it would handle your system well enough.

That's about the minimum you would need to spend to get an excellent PSU.

But like I said, you probably don't need to. Just for an apu system a lower end (but not completely junk) PSU will be sufficient.

Idk, I don't have knownledge about It.
They testing It here in 1:40, Ripple 40~43(always less than 60), 98.8% Power Factor, 85.3% Efficiency, talk about caps and construction in 2:40, cap Nichicon 105 ºC, filtre(4x Y caps, 2x X caps, 2x CM chokes, 1x DM chokes, 1x CAP004DG, 1x MOV), good welding.
In 4:43 He said that "Aris"(Aris Mpitziopoulos, I guess) was helping in selecting manufacture and some components. Apparently CWT manufactured this PSU. In 6:56 they force It to see the limits, turning off in 8:22 with 622W, Ripple around 70, 83% Efficiency. Again, idk what this things means and if this is good quality and, based in consumers bad reviews, I trust this is bad and doesn't worth money.

What should I get that don't will be too much overkill for my setup? How much I will pay for It?

Thanks. Bought this. 7y warranty, hope lasts forever.

It's a quality unit, and given the minimal load it will be under it should last a long time.
