Cooler Master MWE 450W Bronze suitable for RX 5700?

[KNLMN]

Goodmorning guys,

 

I'm not completely sure where to put my question so if the topic is in the wrong section my apologies.

 

Since the release of the RX 5700 I've been interested in purchasing one. Currently running a RX 570 MSI 8GB and my current PSU is a Cooler Master MWE 450W Bronze. 

If I calculate the wattage with pcpartpicker it does say the PSU would be enough and I wouldn't run into problems however I wanted to ask you guys as a second opinion. 

What are your thoughts on this combination? Do I need to upgrade my PSU?

 

Kind regards,

 

Total PC specs:

- Asrock B450M Pro4

- Ryzen 5 2600

- G.Skill Aegis 2x8GB

- RX 570 8GB

- Cooler Master MWE 450w Bronze

- 2x Sata SSD

It will do

AMDs recommendation is a 600W unit. Your unit is a tier B- unit so not optimal for a GPU with 2 Power connectors.

But it think it will be ok. Just dont try to OC and or not running the system on full thrust for days

Thanks for the replies guys, 

 

Just for my information. What would actually happen if the PSU isn't enough for the card. Would the system just, not boot, or would it damage the system?

In the case it wouldn't be sufficient I could always purchase a new PSU afterwards.

It will not damage. Your psu is good enough. But if you overclokc too much you can get a blue screen, but i think you re good with that psu.

No, it wont damage your system

assuming it's the v1 (which it probably is)

 

i wouldn't recommend to do so, as it's group regulated

 

for detail:

what you need to know now, the voltage on 5v can go up, quicker degrading components. it's recommended from me to pick up a good dc-dc regulated unit

not if too much power would be used... that would literally just cut power because OPP is a thing

Goodmorning guys,

Probably just undervolt the GPU so it draws less power, it should work just fine anyways, your system isn't going to draw more than 350W under a gaming load.

Undervolting is recommended anyways. Less power draw, less heat, quieter fans, less wear on the GPU. I'd highly recommend dropping the stock voltages a bit

Thanks for the detailed explanation, however when I look up specific model at Cooler Masters website: https://www.coolermaster.com/catalog/power-supplies/mwe-series/mwe-bronze-450/ it actually tells me it's a DC-DC circuit design.

 

What's the difference between the one at the website, and the one you explained about in your detailed post?

wait... it is? i feel like i'm confusing two models then or something. i'd swear only v2 was fully dc-dc

 

i have nothing to answer currently, as i'm not 100% sure about mwe at this moment

I have a hard time believing they are lying on their own site, however you seem like a godfather in PSU's and want to believe you as well haha.

 

Let's state it this way. If the MWE is actually DC-DC regulated, would it be safe and sufficient enough to power the RX 5700 at stock speeds? Not talking about the reference model but a cooler, more quieter one.

as much as some see this that way, i still work on common sources for now. i don't expect them to lie, and i'm probably at a different model here.

 

if it's dc-dc and all protections are tested and working according to cm's specsheet, this is perfectly fine, even if a bit borderline on wattage when overclocking

 

but again, in worst case it'll literally cut power, so you got nothing to worry about
