Vega 56 PSU Wattage Recommendation

Go to solution Solved by loculus,

If it's a G550M, that's a good model from a few years ago. If it's a GX550 CM Storm, I think that's decent. Some of the older GX550 / GX550 II might be worse but it would probably still handle the build with a Vega 56 unless you have a highly overclocked HEDT CPU. The newer MWE Bronze 550 should be fine though probably not as good as the G550M.

Hi,

I had a RX 480 which I sold out last week. Now I want to get a VEGA 56. I have a 550W(Bronze) PSU of cooler master.

 

So, my question is can I use this PSU for VEGA 56???(I used many calculator . They showed a 485W recommendation & needed about 435W.But they Suggested a 650W PSU)

Screw power draw calculators. They over estimate numbers to sell more expensive PSU.

 

What is the exact PSU model? Wattage is enough, but if the model itself is bad then it's better to still replace it.

I recommend 600w at least. I have great experience with fully modular Corsair RM650x 80+ gold

Should be ok as long as you don't go crazy and raise the power limit a ton.

 

Also remember to undervolt, Vega stock voltage is some crazy number like 1.2. Usually you can undervolt to 1.05-1.1v ish and bring the power consumption down AND improve performance (because with 1.2v you're hitting the power limit max throttling clocks but when you go lower it can boost higher due to power limit not being the limiting factor)

550W is more than enough assuming it is a good PSU.

Comic sans huh?

What exact PSU is it? 550W is enough but Cooler Master has lots of shitty low-end units and I don't think yours is a good one.

If this is your PSU, then it might not keep it's performance for long due to bad capacitors used.

It costs approx. $100 but it is really good PSU. All japanese caps, fully modular cables, Tier 1 quality, 80 Plus Gold

Vega is hungry and GPUs tend to have big power spikes (normal GPU power behaviour). This PSU seems to me like a cheap shit, get the one i recommended

What will happen if I use G550M ?
will this damage any components???

It might not hold up, degrade and eventually die with the big possibility of taking down another component (mostly GPU)

I always like to have a bit overpowered PSU because PSUs have their highest efficiency around 60%, if you push a PSU to the limit, the efficiency goes down, so its always better to have overpowered one

then wthat they mean by 80% bronze or gold???

It says that the PSU has higher efficiency - the efficiency lasts longer when you look on the graph. Nothing under 80+ Gold is really worth it

Dont scare him like that. With questionable capacitors the G550M still scored nice results on open box test

No need to get a new PSU in a rush, just buy when you save up enough money. It's ok to use Vega 56 with the G550M for a while as long as you dont overclock the crap out of the card.

So, you're saying, nothing bad will happen unless I overclock it.(then there's no reason of changing it, Right??)
What will happen if I undervolt it?
