Should I use RM850X or the RM1000x?

Recommended Posts

Posted · Original PosterOP

Hi all, after finishing my watercooling loop I have been made promptly aware that the loudest component in my PC was actually the power supply, a CX750M. While not a bad power supply by any standard, the fan is quite loud at the loads I’m putting on it(300 watt Vega 56 @ 1.7 Ghz something something load i7-6800K @ 4.1 Ghz). I was looking at replacing it with an RM unit, and I was wondering if the RM1000 would be worth the extra 40$ over the 850 for my use case, in which I’d prefer silence, but if there’s no meaningful difference I’d rather not spend more than I have to. Thanks in advance for any and all advice!

650x is all you need, and PSUs are most efficient at around 50% load so you'll fit right in.

You don't need an 850w PSU, let alone a 1000.  Not even the 750.

 

Get a good quality and quiet 650w.

get something tier A+ or higher for way too good PSUs. tho id look at tier A

 

you dont need more than 650w PSU to power that quietly. 

 

RMx 650x is a very good PSU choice. no need to spend excessivly.

i dont think he wants to keep that 6800k forever and he probably doesnt want to replace his psu every cpu upgrade

How did you make the leap that he's going to upgrade to the 10990XE?

If you'd like silent operation with no fan spinup the rm1000x is a better bet. I have an RM850x in both my systems, psu fan in my main pc (9900k/2080S) spins up only at full load. otherwise it doesn't. My second PC (2800x/1070) even at full load for about 20 hours in about 20C room temperature, PSU fan doesn't spin up. I do 3D and VFX Renders at home so I know alot about fan noise as both pcs sit in my bedroom where i have to sleep and i can't sleep with alot of noise.

This is true, but the next chip I buy will likely be when DDR5 debuts, and barring major improvements in the value sector it will most certainly NOT be an intel processor. I will be going to college for an as yet unspecified data science degree, so that’s a use case to consider for the future.

At 20$ more for 200+ watts I’m definitely willing to pay more, I’m just wondering at the value proposition for the jump from 850 to 1000 for +40$.

Thanks for the insights! What’s your ballpark estimate on power draw for the i9 system?

my best guess is around 500w tops, 9900k, 2080S, 4x ssd, 2x hdd, 360mm AIO and some LEDs.

Yeah I think that's about where I'm at, I'll probably be going with the 850  then. Thanks!
