EK, a premium computer liquid cooling gear manufacturer is launching a pump-reservoir combo unit belonging to the Classic Line, the EK-XRES 250 SPC PWM Classic RGB - Plexi (incl. pump). These pump-combo units offer a streamlined Classic look and are an entry class combo solution that is able to offer great hydraulic performance complemented with RGB LEDs for modern aesthetics.

EK-XRES 250 SPC PWM Classic RGB - Plexi (incl. pump) comes with a 250 mm tall reservoir with an integrated EK-SPC 60 water pump that offers 4-pin PWM control for allowing the pump to adapt to thermal load. The reservoir is a tube design made of see-through acrylic thus increasing the RGB LED effect. Bellow the reservoir sits the pump-top which is of square design in line with the rest of the EK Classic product portfolio. The mounting is done from the bottom side, utilizing the 120 mm fan mounting holes.

The integrated 12 V 4-pin RGB LED strip is compatible with popular RGB sync technologies from all major motherboard manufacturers.

Availability and pricing
EK-XRES 250 SPC PWM Classic RGB - Plexi combos are made in China and are readily available for purchase through the EK Webshop and Partner Reseller Network. In the table below you can see manufacturer suggested retail price (MSRP) with VAT included.

MSRP: 99.90€ or USD $104.99.

"entry class combo solution"

IMO $105 is a little high for "entry class". This is what I would consider entry-level.

This man has good taste in water parts. :)

I'd pay a bit more also to feel more secure (sleep better at night) using higher quality water parts, but I'm usually the odd man out. :oops:

Grabbed this sub-assembly way back in 2017, not certain why Singularity Computers prices are higher, but I wanted that crystal clear aesthetic.

D5 pump cover solid black $52
D5 base mount solid black $15
D5 clear plexi pump top $61
Aquacomputer D5 PWM pump $85
Bitspower sleeving custom length and molex plug - parts and labor $10

$223 total plus sales tax, ouch. :oops:

...flip-side is, it's never been wet, dramatic change in build plans midway through. So sad, but I don't have the heart to sell the parts. :cry:


Had an EK Maximus VIII Extreme monoblock (CPU and VRM) heatsink and EK pumptop-res combo in service from 2016 to 2018, never a single issue, no leaks, no drips over 26months, using Bitspower fittings and Aquacomputer D5.
