The latter, it's a low/mid-range PSU and i'm not even sure if 750W is enough for RTX3080Ti, it's practically a RTX3090. But i guess, if it's your only option then as long as it indeed works - keep it.

Just to add some info, I have a Thermaltake Toughpower GF1 PE 750w, with a EVGA FTW3 3080Ti and haven't had any issues, tested using Furmark and Prime95 on a 9900k with a 4.9Ghz all-core OC.

 

So the 750w depends on your power supply.

@jonnyGURUAny significant differences between Corsair SF CP-902015 and 2018 ?

What is a "CP-902015" (that's one digit short) and what is a "2018"?

Nevermind, i've seen two 600W Corsair SFs and for some reason forgot that there exists 600W versions of both SF Gold and SF Platinum.

When is Rev. 14.8 going to be applied to the tier list?

Just guessing but pretty clear. Casing exactly the same and also the history of be quiets sfx.
Of course there maybe small differences bit 1 I predict is that Be Quiet will have worse capacitors as they pretty much always put 85c on their cheaper psu with short warranty, and their lower wattage model is 300w vs fsp 350w. I have fsp aurum 400w and be quiet e9 400w. Same psu but the FSP has 105c primary cap, be quiet 85c so they've done this before.

@Juular Seems like the VTE X2 Bronze has been reviewed:

So what tier do you think this belongs to?  Tier C?

Looks like, yep.

The PSU seem to use a DC-DC + DF topology isn't it?

Double forward for sure, whether it's DC-DC or double-mag amp i'm not sure, there could be switchers on the solder side, and small heatsinks sticking through it surely suggest that, regardless it's still tier C either way. Not sure if i want to put it in normal priority subtier, this review is barely sufficient.

It looks like a platform similar to the Micronics Classic II Bronze. (Made by CE Link! )

According to Micronics, it is a Double Forward/SR, 5V DC to DC, 3.3v mag-amp. Holy creepy...

Hi,

I'm new here,

is  Cooler Master MWE Bronze 550 V2 [MPE-5501-ACABW-BEU] a B tier PSU? is it good?

A decent budget unit. However, in some countries, it is only sold for 230V. In this case, the tier may be lowered.

 

If you can get CX or CX/F for a similar price, that's even better.

how many volt should i be looking for?
i'm in indonesia and that's exactly what was offered, 230v

 

i actually wanted a CX, or seasonic GC but both OOS, kinda frustrating lol

230V only means cost savings on the primary side of the PSU compared to free voltage. If the input voltage (AC) is unstable, the PSU may fail.

 

You can get more support by posting a new thread asking for help in choosing a PSU.

I'm buying a Thermaltake Toughpower Grand RGB 1200W Platinum unit.  https://www.amazon.ca/Thermaltake-Toughpower-Crossfire-Continuous-PS-TPG-1200F1FAPU-1/dp/B077Z6DSXT/ref=sr_1_25?dchild=1&keywords=1000W+power+supply&qid=1627288736&s=electronics&sr=1-25

 

I can see that the iRGB 1200 is at the top of the list, and the Grand RGB is way lower. This is where I'm confused.

 

Here are the Cybenetics reports for both of them. 

 

iRGB: http://members.cybenetics.report:5050/d/cybenetics_xAT_eu.pdf

Grand RGB: http://members.cybenetics.report:5050/d/cybenetics_P3N_eu.pdf

 

Now the tests are very similar, but the thing that stands out is every single component is the exact same, on the primary and secondary sides, and the 5VSB circuit. The one difference is the main switchers on the Grand are A26N60EFL, and A25N60EFL on the iRGB.

 

They both got the exact same certifications as well. So what makes one any different, let alone that much better? 

 

Any help is appreciated, thanks!

Tiers A and B require OTP. Aris couldn't trip OTP on 1000W unit in his review even up-to 200°C. But on 1200W it tripped at 160°C, and on iRGB Plat 1200W it did too at 130°C. No idea why such discrepancies but this is CWT and i'm sure they know how to setup OTP properly it's probably was a request from TT to set it higher. That said, if it's still higher than 200°C then it's hardly useful at all but i'd probably move it back up to tier A as an exception in the next revision.

Probably just Aris's testing.

Maybe, i imagine it's not as simple as sticking the PSU in the hotbox and waiting until it melts. But his reviews are literally the only reviews in the web with OTP tests, so unless you or maybe GN start doing reviews with protection tests he's the only source we have.

Thank you for your responses. Much appreciated.

Things happen.  It's weird.

 

I was doing OTP testing the other day.  Threw the PSU in the chamber, increased the temp every 30 seconds, got to 70°C and it shut down.  Sent it off to the lab.  They said it got as high as 80°C and it never shut down.  Send it back, tested it in A DIFFERENT CHAMBER and got it up to 70°C again and it shut down.  I want to go to the lab to see what they're doing wrong, but COVID....

What about the cooler master mwe v2 B version? Should it go to the new B without any problems
