Epilogue
There is no RM650x (ATX v3.1), providing a tremendous edge to the RM650e (ATX v3.1). There are not many 650W PSUs compatible with Intel’s newest ATX spec (and the PCIe CEM 5.1), so the competition is not fierce in this category. With its 12V-2×6 socket set at 300W max output, the RM650e can support the upcoming NVIDIA RTX 5070 and 5070 Ti models, which have 250W and 300W TDP, respectively. That said, if you use other power-hungry components, you will be left out of power, and you should also take into account that having your PSU operating at high loads all the time is not beneficial for its longevity. The efficiency will be lower, too. The best load range for peak efficiency is between 40-60% for most PSUs. It is like the engine of an airplane. You only push it at full throttle during take-off, when you perform a go-around or want to avoid a stall.
Remember that overclocking can substantially increase the power consumption of individual components, CPU, and GPU, so buying the strongest and best PSU you can afford is ideal if you want to push your system beyond its official limits. For example, an Intel Core Ultra 9 Processor 285 has close to 450W sustained power consumption with an Extreme Performance profile applied!
The RM650e (ATX v3.1) is among the few good choices in this capacity range, and its price is fair, given its specs. With 30 dollars more, though, you can get one of the best mid-capacity PSUs available in today’s market, the RM750x (ATX v3.1), so consider this, too.

Hello Aris, such great work your providing the community! Now that my eyes are open I feel like they should have never hit the market from the beggining, an example is the FSP Vitas, I was about to buy one but was hesitant because you made very explicit about the Yang Loo fan being very weak, so I did some research and Voilá there seems to be an increasing number of people who bought a Vita some months ago now posting videos about fan noise and asking for advice. I mean the Vitas are amazing as far as voltage regulations goes and whatnot, but should a product that is bound to fail shortly after being sold really be put out to the market? It’s not so easy finding a Psu we can trust
So about this Rme650, the Inrush Currents are really high, will that be an issue or is it good? I’m thinking it might be good due to the new gpus needing very short power spikes but then again I’m not totally familiar with the concept and also your graph states that Lower is Better, pls if you can take the time to briefly elaborate I’d be very welcome! Seems like Corsair adopted Cybenetics approved test so cheers on that
Hi! High inrush currents are not good, but it is not easy, at all, to completely drain the bulk cap(s) as we do. High inrush current means that with a completely drained bulk cap, the PSU asks for way to much power, which can even trip the electrical relay connected to the AC socket. As for YL fans, they are hit and miss unfortunately. Really bad idea from FSP to use them and I told them to switch ASAP to something better.
I get it now! So my lack of in depth electrical knowledge assumes it shouldn’t be a problem unless the bulk caps go bad or the psu is disconnected from the ac plug for a very long time? For high inrysh currents psu would it be better prior to the 1st ever use to plug her to ac power and turn the On switch for the bulk capacitors to fill up??
Also, I’m thinking of getting this Rme650 to go with a 330 TDP gpu (7800 xt overclocked) and 65W ryzen 7600, for a total of 450W, just 2 quick questions please:
-Do you think if in the future If I go for something like a 9800x3d while keeping a ~300W TDP gpu it would be problematic?
-Also, this psu only comes with 1x “12v-6×2 to 2x8pin” cable, but it’s only rated for 300W, isn’t this a problem for a 330W gpu? I think it’s my only way of connecting the gpu with this cable… because the psu only has 2x8pin Cpu/Pcie connections so I need 1 for Cpu and I don’t know if I should connect the gpu (which has 2x8pin) to only 1x8pin on the psu.
1) 9800X3D has low power consumption so even with a 300W GPU this PSU will be ok
2) If the GPU needs 330W then it will probably won’t work with the 300W set 12V-2×6
Thank you Aris! I actually ended up going with your suggestion “you can get one of the best mid-capacity PSUs available in today’s market, the RM750x (ATX v3.1), so consider this, too” and I already have a Ryzen 7700 with me and waiting on a Palit 5070 Ti. So my plans sidetracked completely and ended up getting a different Psu, Cpu, Gpu. Ahahahah
Is there a Paypal where I could buy you a beer?
Much *more* success to you and your team Aris, thanks for the help!
this little rm is the best cybernetic power AND noise sold in rm series sold by corsair
Speaking about Corsair …
I own rm 1000x 2024
Rtx 4090 super (right now)
Ryzen 9800x3d
For future Rtx 5090 is good way to go ? This psu will handle it ? I searched whole psu’s models on your side and I’m looking for sleeved cabled / individually so u pick this one.
yes it will be ok
