Swiftech rolled out its new flagship pump for liquid cooling setups, the MCP50X. Measuring just 62 mm x 62 mm x 44.8 mm, this compact pump unit can drive 4.8 mH2O of coolant pressure, with up to 14.3 LPM of discharge. Its brushless DC motor drives the pump between 1,200 and 4,500 RPM, with a maximum power consumption of 25.8W. The unit gives you power connectivity choices between 4-pin Molex, and SATA. Its ports stick to the G1/4 threading standard. Available now, it's priced at US $69.95 a pop.
In addition to the MCP50X pump, Swiftech rolled out the Maelstrom V2 Dual Bay Reservoir. Pictured below, the reservoir takes up two 5.25-inch drive bays in your case, and provides about 355 ml of coolant capacity. The reservoir comes with a factory-fitted MCP50X pump unit, which can drive coolant at up to 14.3 LPM. The actual reservoir is made of clear acrylic with LEDs that draw power with 3-pin fan connectors; while the bezel is made of black anodized aluminium, and the inner chassis of nickel-plated steel. A cutout in the front bezel lets you take stock of the coolant levels. Also featured is an anti-vortex intake partition. Available now with several customization options, the Maelstrom V2 is priced at $139.95.
i wonder if they fixed the heat issue. The 35X required a passive heat sink if I remember correctly (maybe it was only for the dual top version). Wasn't a big problem, but another like $30-50 $14.95 for single pump heatsink or $27.99 for dual pump heatsink
This is definitely on my to buy list though.
Same square body dimensions (62x62mm) and about 3-4mm taller than the mcp35x.
Edit: Got beat to it. Don't go by Max discharge, no one ever sees that in a typical loop once restriction comes in play. This pump is cheaper, supposedly more reliable and silent/cooler, and has a higher head pressure.

I don't read anything about it being PWM controlled. But its RPM have to be controlled somehow.
The 35X is more expensive and PWM controlled and doesn't need a heatsink.
This is PWM controlled, and the 35x really needs a heatsink if tuning it down. Best part- SATA power cable, sleeved at that. Molex should die off already!

This. It is also PWM controlled and has a SATA connector for power. It has higher head pressure which is much more important and relatable to real-world usage, and 30% cheaper because Laaing is not involved.

The 35X is not that bad at full tilt, though I doubt anyone is running it past 60% PWM. At 55% and under it's not very obtrusive. Looking at the 50X, it looks like a nice refinement, drop the things that are not useful like all that extra flow above 2GPM and boost the head pressure. This would be a great pump for starters, it has enough pressure for beginners who tend to outgrow their pumps perhaps.
The price is definitely attractive and from what I remember it's supposed to be more quiet (always a plus). Must be difficult getting that extra pressure considering 18W vs 25.8W between the two pumps. Stren should be getting one of these for testing.
Sort of random question pertaining to pumps and PWM in general. How does PWM % correlate with power usage? My basic, overly generalized understanding of PWM is the device always recieves 12V but is shut on/off at a certain rate. How would say a MCP50X's power draw at minimum PWM/RPM compare to it at full 100% (25.8W).
Swiftech's chart gives current draw as well and shows something like a minimum of ~13W and max of 25.8W. What's interesting about this to me is the fact the H220X's pump is the MCP50X tweaked for a max RPM of 3000 yet the power is 6W. According to Swiftech's chart the MCP50X at minimum RPM of 1200 RPM is around ~13W?

Theoretically, as PWM works turning on and off as you said, the pump will be on for just a fraction of the whole time, being 100% PWM duty cycle meaning the pump will be on 100% of the time. So x% PWM duty cycle means the pump is on x% of the whole time. Remember that 100% = 1, 85% = 0.85, 27,6% = 0.276 and goes on... So:
Power = (Current x Tension) x PWM Duty Cycle
The Current and Tension are constants as you are powering the pump with a constant 12V supply (2.15A at 12V, from Swiftech charts) So:
Power = (2.15A x 12V) x PWM Duty Cycle
I believe it is calculated this way, because it is the most logical way of thinking it for me. Take this as a theoretical calculation based on basic math as I don't actually know how they do to measure that. Grain of salt
Wow that pump/res combo is ugly looking... I'll stick with my XSPC combo I bought years ago for half the price. Somebody explain to Swiftech that simplicity has a lot going for it.

Somebody please explain to tout, "different strokes for different folks"...
