550W PSU for 2070 SUPER and 3700X ?

[Rxd]

Super basic question(I know and I am sorry) but I just want a yes or no. I know that the 2070 super takes no more than 240W and the R7 - more than 150W, both at 100% usage, which will never happen in my case. Also there won't be anything special like RGB strips, multiple drives, etc. that will require extra power.

You need a bigger one probably

[hello_there_123]

Short Answer :  Yes. You DO NOT NEED a bigger power supply.

 

Also what's the model of the PSU? @Rxd

[LukeSavenije]

hm... I'll give it the it depends

 

what model?

[DumboDodo]

Long Answer : 550W might be enough (but barely) but that doesn't mean it's suitable. Usually, you'd want something much higher than 550 for such power-consuming parts. I, for example, have a Ryzen 5 2600 & a GTX 1660 Ti yet I bought a 650 Gold PSU to ensure stability and safety for my build. Use PCPARTPICKER to know exactly how much power your PC can draw (maximum) and multiply that number by...say... 1.4-1.9 Of course, this is pure speculation, but it's still much better than going for a 550W PSU for such a high rig. I really recommend you watch YouTube tutorials on how to choose a suitable PSU and the whole topic in general. Also, never go for a cheap PSU to save money. It's a very vital part of your system that you don't want to cut costs on because a low-quality PSU might seriously damage your system in a lot of cases.

@LukeSavenije Corsair most likely rmx550, depends what the shops will have in stock at the end.

oh, rmx is fine for that

 

just keep in mind you're up a higher load on it, so it'll be a bit on the louder side

Refer to the PSU tier list for some guidance on the quality of your PSU. If you really want to get a 550W one and don't plan to integrate more power-consuming parts in the future, it's fine to get a 550W but it will be on semi-full load when loading your other parts. Yet again, all of what I'm saying is pure speculation based on my limited knowledge, so refer to YouTube videos or so for more details on the subject

@Deathtroya I've watched most of those videos and trust me I am picking a good PSU as a model. At the very least Tier A based on the new PSU tier list

Great! I think Tier A would be very good at handling wattages slightly below its maximum. Might be a bit noisy on load, though

ah... you like the list?

 

i want you to look at the names on it

Yeah I can tell. Literally everything you've said in this thread has at the very least been misleading.

Honestly, It's not as if I want to mislead anyone at all. I just wanted to help him out, yet I wasn't sure of what I told him, so I told him twice that is was all speculation and I told him twice that he should refer to guides or YouTube videos on the topic. People on this forum are really helpful to me when I ask for any kind of guidance so I thought I might help someone out too. I already clarified all of that for him, so what do you have to do with it?

Well, I just did and found out that you're one of its makers, haha! You did really well and provided a lot of help for many new builders, including myself. I referred to it before buying my TX650M, by the way. Great job!

The RMx 550W is quiet even at full load.

yeah... i thought it was worse at that load... i took a look at a graph... boy i was wrong

So, you bought a 650w psu for a build which consumes around 240-250watts while gaming?

Max consumption is 300w. The curve of efficiency is at its best at 50%, which is around my full-load draw. If only you quoted the whole comment, or even finished the sentence, you'll know that I didn't mention the full model to signify that he needs a PSU double his power consumption, but rather to let him know that I, even though my build is nowhere close to being high-end, went for a decent, stable, Tier A gold PSU and tell him that the PSU isn't a part he should save a lot of money on.

The difference is like 1% at most usually lol, no point. Might as well save the $10, will probably be cheaper in the long run.

If these $10 are saved on dropping wattage to be suitable then it's definitely fine. If they're saved by going for a less quality / lower tier model, then I wouldn't recommend it. Personal opinion.

I mean that, yes.

[Vejnemojnen]

well, good PSU-s have roughly the SAME efficiency from 60% to 90% load... So really does not worth to oversize a lot. How did you measure the 300w max power consumption? Drawn from wall socket? Bc in that case, the actual power need of the system is roughly ~10% lower, so 270watts.
