XSPC X2O 500 Single Bay Acrylic Reservoir Pump

Welcome to my review of a brand new single bay reservoir pump, the XSPC X2O 500.

While I have had the opportunity to test many 20 watt+ bay reservoir pumps such as the XSPC D5 Bayres I tested here.  I know from experiments such as this flow sensitivity test on the Raystorm, that CPU blocks are very resilient to operating well at very low flow rates and in custom loops we generally have much more pump than really needed.  That is fine when space and cost are not high priorities, but there is a bit of a gap in pump options that are more value oriented and still have expansion and power capabilities beyond that of a CPU only loop pump. Most of the all in one kit pumps designed for CPU cooling only have pumps in the 1-2 watt range of power, but they are really maxed out and often can’t push flow much beyond about 0.5GPM. That’s where the X2O 500 fits into the picture, targeted for those that don’t have a budget or want to spend over $100 or more on pumping power, but they want something that is still expandable and capable of powering through multiple block and radiator systems as they upgrade.

A special thanks to Paul from XSPC for providing the review sample:



Since it is not yet listed on their website, I’ll just note some specifications that I can come up with on my own.

  • Brushed Aluminium Faceplate
  • Acrylic Reservoir
  • 1x 5mm LED hole
  • Blue Sleeved LED provided
  • Dimensions: 149 x 99 x 42mm

    Thank you very much Martin! Your efforts are greatly appreciated, as always.

    Thanks for the review Martin. As of today its not selling yet to resellers but I’m sure it will be soon. I’d like to see them get the housing black, aesthetics matter in our business.

    This really puts the H100 pump in perspective.

      Thanks Gary,
      housing could be painted easy enough with the pump removable, but it would be nice to have it come in black as the factory color.

      I hope to round up an H100 pump to verify specs too there is not much for detail out there but planning to do some AIO kit testing in the near future and will break them down and test the pumps then. This H100 estimate is based on the specs I could find.

  3. […] een oplossing voor een reservoir en pomp, werd ik wel erg gecharmeerd door de volgende oplossing: XSPC X20 500 Single bay. Mijn vraag is dan ook gaat Highflow deze op de korte termijn (1 tot 2 maanden) kunnen leveren? Of […]

    Tried to get one of these…

    >>Sorry it’s not possible at the moment. We are not happy with the noise level of the pump and we decided not to release it.
