With well over a decade of experience and the products to back up its reputation, Bitspower is one of the most famous brands in the market of PC DIY watercooling. The company gained fame for their wide range of high-quality fittings in different options for function and form alike and built upon it with mod kits for pumps. More often than not, these kits and pumps came in at a hefty price premium relative to the market, but that did not stop them from selling out in most colors whenever batches did come out. We take a detailed look at one such offering today, and thanks to Bitspower for providing a review sample for TechPowerUp!
Readers of this website may have noticed that some of my reviews from last year took place in temporary accommodations as a result of unexpected COVID travel restrictions. What I did not expect, however, was that by the time I got back to my usual setup, this pump would pretty much be EOL. You can still find it in most shops, and it is still up for "pre-order" on the Bitspower shop where you really want to compare this version to newer ones, but I did decide to complete the review. It was sent for review, after all, but more importantly allows me to directly compare it to newer Bitspower offerings if and when I get to those. I had also previously tested the older generation of these, so this will be a good way to compare how Bitspower's pump top and body designs have changed over the years. Do expect this review to include detailed testing, but let's begin with a look at the specifications in the table below.
