is this any good? https://www.newegg.com/global/uk-en/p/N82E16817151075?Item=N82E16817151075

I found some used for about £10 on ebay.

i wouldn't recommend second hand PSUs

 

i think this is something like a m12ii?

So Cooler Master has launched new MWE V2 psus (80 plus bronze and white) 

 

I guess white one will be sh!t but what about the bronze ones they have 5 years warranty where do they belong in the tier list ??

No reviews available for them yet, but at face value they look okay.
The MWE Bronze V2 units are listed on Cybenetics https://www.cybenetics.com/index.php?option=database&manfID=27&volts=1

Manufacturer is listed as Gospower, which I'm not familiar with.

DC-DC, Half Bridge + LLC resonant converter... And they can only manage 80+ White? wut? Looking at the LoadPlugSolutions website the entire 80+ White range was certified as 80+ Bronze, though one of them only got through as bronze by .01%, so I can see why CM wouldn't market it as 80+ Bronze

 

What I don't get is WHY ARE THERE SO MANY MODELS!!
Cooler Master MWE V2 80+ White - 450, 550, 650, 750

Cooler Master MWE V2 80+ White 230V - 400, 450, 500, 550, 600, 650, 700, 750
Cooler Master MWE V2 80+ Bronze - 450, 500, 550, 600, 650, 700, 750

 

That's 19 SKUs! That doesn't even include the original MWE range which is an additional 14 units!
Fuck off with the 80+ White and 230V units. Stick to 100W increments, no-one needs 50W increments in their product stack. Heck, it's a budget unit so you can get rid of the high wattage units as well cause no-one who actually needs 750W should be using a budget PSU. Left with just the MWE Bronze V2 450W & 550W as the only potentially interesting units.

 

Pending proper reviews, if pricing is right I could see these competing against the Corsair VS & CX/CXM range. At the very least it's good to see Cooler Master improving things at the lower end of their product stack.

So let's say you're toying with the idea of a SFF build for whatever purpose.  You've picked your case, but when you go to choose a PSU on PCPartPicker ...

 

Either all the PSUs that come up as compatible are not found on the tier list, or,

NO PSUs appear on PCPP as compatible.  (Some such cases have built-in PSUs, but some don't.)

 

 

How do you decide what PSUs to use when nothing that's listed as compatible on PCPP appears on the tier list, and what do you do when NO PSU is listed as compatible (and you don't want to change cases)?

 

 

I made a couple screenshots showing several examples, which I'll paste below.  I wanted to fit it all in one image, but unfortunately I don't have (nor can I afford) a Dell UP3218K (or 3 - my laptop does have 3 display outputs, although idk if a GTX 970M with 6GB VRAM could drive them all even in non-gaming situations), I'm just stuck with a single 1080p display.  (Even so, I still had to set Chrome's magnification to 50% AND split the data across 2 screenshots.)

Hmm... I thought I'd posted something about what you do when PSUs on the PCPP list don't appear on the tier list, mostly because you've chosen a SFF case that's only compatible with a few (or no) PSUs.  Anyone know what might have happened to it?  I thought I did click submit, I don't have any notification of moderator action, although my internet has been spazzing out a lot.

Your answer is that there are very little good SFX units. There's the SFX Power 2, Corsair SF, and a few more, but that's about it for good ones.

Ahh, but what about TFX, Mini ITX / Micro ATX / Flex ATX (yes those are selectable categories on PCPP), or cases that list NO PSUs as compatible (like the Silverstone SST-PT13B)?  Or in another category (I don't find them on pcpp) how do you determine if a server / rackmount PSU is good?

Came across this: SilentiumPC Supremo M2 Gold. 550watt unit costs ~ 15USD less than a TX550M, and cheaper than BQ PP11 500w CM. I'd kindly appreciate any opinion about this PSU. Can it be recommended? Quality? Only English test I've found was on @jonnyGURU 's site, for the predecessor M1 unit. Is the later iteration a better unit?

I believe those are not bad units, but they do lack OTP, which makes it a pass in my books

TFX & SFX PSUs aren't as popular as ATX form factor PSUs, so there are simply less available on the market. There's also far less TFX/SFX units reviewed by review outlets, and without proper testing and reviews they cannot be included on the PSU Tier List.

 

There do seem to be a few interesting SFX PSUs around these days with the rise in popularity of SFF builds. There's a few already included in the PSU Tier List and I'm sure more units will be slowly added to the list as more information comes available and reviews conducted.

Snip

 

Heya, PCPP staffer here!

 

If you encounter any PSU+case combos that you know to be unquestionably compatible without caveats, but we have it marked incompatible, feel free to let me know and I'll look into it. As you might expect, compatibility for PSUs in SFF cases is very difficult. Much more difficult than compatibility with other cases. That being said, we do our best to show as many compatible parts as we can, though do err on the side of caution when it comes to compatibility, especially with SFF cases.

 

If there is PSU that isn't on the site that would be compatible, you can also let me know about that, and I'll look into getting it added.

hello there!

 

just one thing... could you snip that long of a message?

 

and will you be here once in a while so i can request stuff?

Good call. Taking out just the images was such a snip that I was barely noticing how much was left after

 

I will indeed be around. You can always shoot me a message or whatever to let me know of any corrections or addition requests. You can ping me on Discord instead too, if you'd like.

Why 230V units are bad just asking .... I mean in my country 220v-240v comes 

 

And if they can compete with corsair cx (grey units) i will be very happy as here in my country mwe550W v2 bronze costs just 7$ more than cx450

230V only PSUs can only handle lower current on the primary side that the higher voltage allows. Much cheaper components used in the primary, not able to handle a wide range of voltage (higher currents). Basically just a cost saving measure to make a PSU as cheap as possible. If your mains voltage is a stable 230V it's not really an issue, but if you live somewhere with brownouts (like a lot of Asian countries) the mains voltage can drop low enough that it can cause issues for a 230V only PSU. As the voltage drops out of the 220-240V operating range the current will increase beyond what the PSU is designed to handle, potentially damaging the PSU.

 

Most [decent] PSUs are what is known as full range which can handle the full range typically spanning 100V to 240V. These are a little more expensive to make, but are designed to be more robust to handle higher current on the primary side.

I think my point was if you're going to make full range units in the same product series then why make the 230V as well? Sure you might save $1 on the unit but you just end up having to market 33 SKUs under the one product name.

lol , i was told skeptical of my 750w vengeance silver being in tier b and not its separated specifically by the bronze and silver one , now its in tier a , woohoo lets hope it doesnt explode

 

nothing from tier b and higher explodes... even most c's aren't going to

 

but would you mind to snip it? you literally just quoted a whole list...

Can I bring to the attention the quality of the PSUs used in PCPP's featured build guides? Often included are units such as the EVGA G3 and SeaSonic M12II, that are, while popular, lacking critical protections (may lead to fun fireworks coming out of your computer) and having bad electrical performance relative to the price point, respectively.
