I've been going back and forth between different brands of PSU's, mainly the Phanteks AMP, ASUS Rog, Seasonic and Corsair RMx and RMi.
Current Setup:
I'm trying to decide on a case between the Corsair 220t Airflow, Lian Li Lancool II or a Phanteks P600S. With the latter two I'll likely be adding 3 more Corsair ML120/140 fans.
I've basically decided on a Corsair RMI, to work with the other Corsair components, the Corsair software and monitor power (also adding a Commander Pro), but I'm stuck on which one to get- 650, 750 or 850.
I calculated my current load here, including with any foreseeable upgrades, and it came out at just under 500W.
I have never done any overclocking and I'm not sure I will, but at some point I'll update the processor to either a Ryzen 9 3900x or 3950x...which both are 105W like the 2700x currently installed.
The 650 and 750 both have 3 CPU(EPS)/PCIe connections on the PSU side. The 850 shows five. From what I read the CPU and PCIe connections are interchangeable.
Here's what I'm not sure about. I need connection for 8 pin EPS, one for 4 pin EPS, and the 2070 Super takes 8 pin and 6 pin.
Obviously the 850 has connections for each, but I didn't plan on paying over $200 for a PSU. With the 650/750 having three connections I figured one for each 8 pin and 4 pin EPS cable and the third connection for a dual 6+2 PCIe cable.
I was thinking since they actually include a dual 6+2 PCIe cable there is no issue with this, but I was also wondering if it would be better (power/load wise) for the 8 pin and 6 pin PCIe connections to have their own cable/connection to the PSU.
The best prices I found are-
RM650i- $115
RM750i- $177
RM850i- $220
MSRP for the RM750i is $149.99 and RM850i is $169.99, but on Corsair.com they are out of stock and no retailer has them for those prices, otherwise this wouldn't even be an issue...I'd get the 850.
I'm not sure how much of a 'cushion' over the 500W load is enough, say if I went with the 650.
I emailed Corsair to ask these questions, plus when the 750 and 850 will be back in stock, but the response I received didn't give answers and said they would pass the message to others...and no further response yet.
Any help would be greatly appreciated!
