Jeremy Q.Top-tier after-sales service!
I received my PC with a faulty graphics card. The flowup after-sales service was ultra effective. They replaced my card the same day (shout-out to Mickael, who was really great).
Lenny N.No regrets!
I invested in the BlackHawk and it’s pure bliss. With the Cooler Master MK770 keyboard and the MSI IMMERSE GH20 headset, it’s softer than my bed. And yet I love my bed—trust me!
The after-sales service is genuinely high quality. The replies and help provided are quick, with kindness and real human interaction.

I ordered a made-to-measure PC on this site—I was very well guided based on the use I wanted to make of it, but above all I got my money’s worth.
I contacted the after-sales service several times to get some answers. They were very responsive. I strongly recommend FlowUP when buying a PC.

MORE THAN JUST A PC, AN EXPERIENCE
At FlowUP, everything starts from a simple observation: too many PCs are poorly assembled, overpriced, or not properly supported.
So we decided to do the opposite:
- ✅ Clean builds
- ✅ Tested
- ✅ Optimised
- ✅ Reliable components
- ✅ Zero no-name.
- ✅ Neat assembly
- ✅ Real after-sales service
- ✅ Ready to play machines
Ready to play without compromise?

amd ryzen 5 5600
The AMD Ryzen 5 5600 processor is an attractive solution for mid-range PCs, suitable for gaming as well as photo and video editing, while still offering an excellent value for money.
With 6 cores and 12 threads, it delivers solid performance and sits just below the Ryzen 5 5600X in terms of price. The Ryzen 5600 uses a chiplet design with 32 MB of L3 cache, bringing it closer to the 5600X, while the 5500 model, based on the 5600G, disables the integrated GPU, reducing the L3 cache to 16 MB and supporting PCIe 3.0 instead of 4.0.

I bought from flow up.
I recently purchased a PC assembled by Flowup, and the experience has been flawless. The assembly is incredibly neat (perfect cable management), the components are of high quality, and the performance is exactly as advertised—if not better.
Special mention for the secure packaging—the PC arrived in perfect condition. I recommend it 100% for anyone who wants a powerful machine without the hassle!Date of the experience: 13 February 2026

FAST DELIVERY AND EXCELLENT PERFORMANCE.
I received my PC in exactly 9 days! (Order placed on 10 February and received on 19 February). I’d like to thank the Flow Up team for their speed and sincerity.
As for my PC, it’s the Savannah v2 equipped with an RTX 5060 Ti and a Ryzen 7 5700x with 16GB RAM. It’s perfect for playing in 1440p on high/ultra settings on big triple-A titles with 80/120 fps, and for esports at 240 fps on low/high settings (depending on the games).
