[SOLVED] Coolermaster MWE 550w 80+ Bronze vs Corsair CV450 ?

[_christophercc]

So i have a brand new pc and i accidentally bought 2 psu's (CM MWE 550W 80+ Bronze & Corsair CV450 80+ Bronze). I don't know which one to keep. I have:

Ryzen 5 2600
GTX 1650 S

we don't have cx series and evga available in our country.

no plans on overclocking

You can keep the CM one as it leaves more headroom for your system but Corsair CV is of a better quality.

Corsair CX> Corsair CV >Cosrair VS

Though I mostly agree, CV and VS are mostly similar; except that CV is just VS updated to meet 80 Plus Bronze certification. Hence, it may be a tad better internals-wise.

Do you have the MWE 550W V1:

MWE Bronze 550

Cooler Master's family of power supplies feature a line of stable, quality, 80 Plus Bronze power supplies. The MWE Bronze series is compact and available in outputs suitable for most systems. On top of safety regulations, the MWE Bronze includes Cooler Master's 3 year warranty. Inside, the...

Or the V2:

MWE 550 Bronze - V2

The MWE 550 Bronze V2 offers 80 Plus Bronze certification, guaranteeing an average efficiency of 85% at typical load. The DC-to-DC + LLC circuit design allows the unit to convert power to components reliably, efficiently, and safely for better overall performance. This unit operates in silent...

They differentiate through their model numbers:

• V1 - MPX-5501-ACAAB
• V2 - MPE-5501-ACAAB

Big difference is that the V2 uses the newer (and much better) DC/DC LLC resonant design. The <=550W V1 are group regulated.

The Corsair CV450 is a bronze certified Corsair VS => similar old group regulated designs for both.
So if it's the MWE V1 I'd still take that over the CV... both low quality and very similar, higher power output one I guess. If it's the V2, clearly keep that... is a whole lot better.

I think i have the v2 of this cm because it says it's a dc-dc design.

i still don't know if it is v2 though... it's in a purple box

You need to look at the model numbers... I said in my comment above:

• V1 - MPX-5501-ACAAB
• V2 - MPE-5501-ACAAB

You'll either find the model number printed on the PSU label itself(you need to open the box) or on the online listing from the shop you've bought it (they should list the model number on their specifications section).

EDIT: The model number should be printed on one side of the box as well.
