[SOLVED] Is my pump strong enough?

Ok so, I'm planning on water cooling my PC real soon and so far I have found all the parts pretty well, except for the pump and the reservoir. Originally I was going to get a Thermaltake D5 Reservoir-Pump Combo except they only have the 300ml reservoir size. I would much rather prefer a massive, over-the-top 600ml Thermatake T33 but unfortunately they don't make a pump-reservoir combo for that size. I'd be willing to settle for something a little smaller like a Thermatake R33(500ml) or an EK-Res X3 400(400ml). Also, note that there is a 400ml pump-reservoir combo called the Enermax Neochanger but I've read from the reviews that it is pretty bad and about 30% of them fail after 2 months, so I'd rather not risk that and I would prefer to buy from a more well-known brand. The problem is that I've only seen one pump used to power massive loops with massive reservoirs like the T33 and that pump is the Thermaltake Pacific P1 which is like 250$ which is way over my budget (i'm looking for something around 100-150$). So my question is whether there is different pump which can still push the water through my loop, or will just a regular EK Revo D5 do the trick? My watercooling specs are: Thermaltake Core P5 case, using PETG 12/16mm, EK HDC fittings, EK Cryofuel Azure Blue coolant, Thermaltake Pacific RL480 radiator, a Phanteks Glacier C350i cpu waterblock for a 7700k, a Phanteks Glacier gpu waterblock for GTX 1070, and at a later date, I might potentially extend the loop into my motherboard (an Asus Maximus Formula IX) which has a built in waterblock. Also when I do find the right pump for my system, I would like to attach it directly to the bottom of the reservoir so its not separate. Do any two pumps and reservoirs just screw together, or is there some special fitting I could use, or will I just have to keep them separate and just connect them with two more fittings and some more PETG? Thanks,

Thermaltake Pacific P1 uses a D5 pump, just like the 300ml one you originally mention. Also the same pump used in the EK D5 Revo. These are all the same pumps, just a different brand name and different reservoir model, so you're really just comparing the exact same pumps to one another. The only one really different is the Enermax Neochanger which is more of a VPP755 style pump with a little higher flow, (D5 is a 655, 755 is an updated version), but I might be wrong...might be a completely different model line. I did the review on the Neochanger for Tom's - decent pump.

Also, reservoir volume has nothing to do with pump size or ability...it just holds more coolant.

Radiators are some of the least restrictive components in a watercooling loop, so having 'massive radiators' really isn't causing you undue restriction. Tight bends and excessive use of fittings is where you run into restriction issues.

Long story short - most of the pumps you are thinking are 'different' above are actually the same pump.

Tell me your loop components and I'll tell you if you have anything to worry about.
