Best budget PSU

[ears.ears]

Corsair's PSU lineup has had a big increase in price ever since the tariffs. The CX450 went from being $42 to $50.

However, the Seasonic S12III 500W is $42 and contains the same topology as the CX450.

In a budget build (2600, 580) is the $8 saved worth it?

So we finally confirmed the S12III is LLC with DC to DC? Is there a link to the tear down?

Also i should've said "primary side topology", my bad. Secondary side is dual mag-amp, not DC-DC.

CX have DC-DC and a rifle bearing vs the S12III's Dual Mag-Amp and Sleeve bearing fan.

I'd say those upgrades are worth the extra $8.

The S12III's also appear to have some coil-whine problems across the range.

FYI: That thread really doesn't confirm anything.

We had more constructive discussion here: http://www.jonnyguru.com/forums/show...-DC-DC-finally

Dual amp mag it's not group regulated.
It's in par with DC-DC (Ind).

S12III is rifle bearing too. I opened some to see the bearing

No, because from what I've seen so far, they use an 8pin Protection IC, one that doesn't have an openly available Datasheet...

With that said, its likely they don't come with OCP anywhere, UVP on 12V is still questionable and unknown.
In short:
No, its not worth saving it.

The only alternative, if cheap enough, is the be quiet System Power U9 or 9 depending on region...
As well as some others...

But generally you don't find many decent PSU in the lower wattage area...
