Help me make a decision

The main question is: Corsair RM750x vs Be Quiet! Pure Power 11 600W CM.

So, I'm planning my new gaming build, which i mainly want it to be elegant, powerful but quiet. However, I do have some conditions: 1) i love the looks of air coolers; 2) although money isn't that much of an issue (i don't care if it takes me a few months complete the full build) i do have to ship everything to Colombia, and sometimes shipping costs even surpasses those from the parts themselves and that's just stupid. I haven't bought all the pieces yet, only the CPU, motherboard, RAM and the m.2 ssd that i'll list below, but i want you guys help me with this issue:

I've used many PSU wattage calculators they always give a recommended wattage of 590+ (actual consumption is in the mid to high 400s, depending on which calculator i use); so basically, a 600W PSU. So i had my eyes on the Be Quiet! Pure Power 11 700W CM, which is semi-modular, 80+ gold rated and, checking some reviews, runs rather wuiet even under load, but it suddenly became unavailable for international shipping on amazon and newegg. However, the 600W version of the same PSU is available and for an AWESOME price. However, at 600W i'm not as sure about the decision, specially because i need it to actually be quiet (lol). Enters the Corsair RM750x; fully modular, 80+ gold and a long-time known good PSU; however, it costs almost twice as much as the be quiet pure power 11 600w. I know i said money isn't an issue, but taking into account that i still need to buy the case, cooler, a couple of case fans, psu and gpu, the difference here would mean a 1-2 months delay in finishing my build. So i need hard arguements to help me make the decision.

The system is going to be somethin like this:

Case: the new Be Quiet! Pure Base 500 black and windowed case; i want to replace the fans for 3 140mm silent wings 3, but that would be the last thing i'll do

Board: Gigabyte B450 Aorus Pro Wifi (rev 1.0)

CPU: Ryzen 5 3600

RAM: 2 x 8 Gb DDR4 3200 mhz Hyperx Fury RGB (although RGB isn't meant to be a strong feature in this new rig, it was only 5 dollars more than the non RGB version)

Cooler: Be Quiet! Dark Rock TF (i know this case doesn't require a top down cooler but 1) to me, it looks incredibly cool and 2) it performs well in all reviews i've seen)

GPU: Gigabyte RTX 2070 super gaming oc 3x windforce (i might go for a 2080 if, at the time i'm actually making the purchase, the price difference isn't too big). I'll try to ahve it mounted vertically with cablemos or phanteks vertcial mounting bracket.

Storage: 1 x HP EX950 M.2 + 2 x Teamgroup T-force vulcan 2,5" 250 gb SSD (don't judge me. i wanna show off my SSDs as the pure base 500 case was designed for haha) + an older 2 tb HDD i already have on my current pc

With those system specifications you are looking at closer to 350W power consumption under load. Ignore PSU wattage calculators, they often suggest much higher wattage than you need as they make money from affiliate links selling PSUs, so naturally they want to sell you the more expensive higher wattage unit.

If you want more accurate power consumption figures then I would suggest looking up reviews that test power consumption of individual components for the Ryzen 3600 as well as the RTX 2070 Super. Personally I find Tom's Hardware reviews is a good place to start and they have a good catalogue of reviews.

RMx is better, but they're both good. As per above you don't need such high wattage, so if it's available in Colombia going with a cheaper unit like the RM550x or even a Be Quiet Straight Power 11 550W might make more sense.
