Overkill? Too much load on pump?

My "case" is a Lian Li DK05 desk. It has space for 2 ATX systems and 3x360mm radiators plus 1x480mm radiator. I did have 2 systems, each with a custom loop using 2 radiators each. I recently did an X570 build to replace the X470 and removed the trusty X58 system on the other side, with it's custom loop.

The new build on X570 has a 5800X and (lucky me) a Radeon 6800. I'm hoping to score a 6900XT in a couple of days and put a waterblock on it, but if I don't the 6800 will get a block. The pump is an Alphacool VPP755. If I forgo the second system and use all the radiator slots for a single loop, is the pump going to be OK with a CPU block, VGA block, 12 quick disconnects (in and out for each part), and 4 large radiators? Or will I even see much benefit from adding another 360mm and a 480mm radiator to the 2x360mm already connected to this loop? I suppose I could to 2 loops (1 for CPU, 1 for video), but that would be a mess of tubing I think I would rather avoid.

wow that's a lot of rads. granted, my system is getting pretty long in the tooth these days but still....i'm cooling both CPU and GPU with nothing but a single 360 rad.

i'm more just curious, what is newer hardware requriing?

The 5800X is rated at 105W and I think the 6800 is 250W. I don't _need_ 4 radiators, but the increased capacity would let me run the fans slower for less noise.

Real power consumption is 142 W sustained for the 5800X and right around 250 W for the 6800, but I agree with the "more radiators = better" mantra (to a point.)
My 2080 hits low 50’s at max usage and it’s a higher TDP version (~270W full load) and that’s with just a single GTX 240 rad. I’ve got 2 GTS 360’s on the way when I add my 2600X to the loop (y). Should allow me to run the fans around 1000 RPM.
