Very positive review, despite comments about delivery time, no issues on my side: the screen was shipped the next day after my order and the PC arrived 3 days later.
Jeremy Q.I received my PC with a faulty graphics card, and the after-sales service at Flowup was incredibly efficient. They replaced my card the very same day (shout-out to Mickael, who really was great).
Lenny N.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—believe me!
The after-sales service is really high quality. The replies and support are quick, with kindness and real human interaction.
Order received in 5 days (weekend included)
Very good condition, good price, and responsive and efficient after-sales service.
I recommend it.
Arnaud N.Honestly, this is a great investment that I don’t regret at all. There’s a really great after-sales service, with fast responses and full of kindness. Honestly, I recommend it without hesitation. Thank you for your work, team! Thanks a thousand times <3
Tristan X.I bought a made-to-measure PC on this site; I was very well guided regarding 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 a few answers. They were very responsive. I strongly recommend FlowUP for buying a PC.
PC ordered on Sunday, received 6 days later with no issues at all. Thank you to the Flowup team. The PC is really incredible—no problems.
Héléna B.Great contact—communicated a new quote directly! The follow-up and after-sales service for picking up the PC on-site are exemplary. Thank you, Nathanaël, for your professionalism!

I bought from Flow Up.
I recently bought a PC built by Flowup, and the experience has been flawless. The build is ultra neat (perfect cable management), the components are high quality, and the performance matches exactly what was advertised—if not even better.
Special mention for the secure packaging: the PC arrived in impeccable condition. I recommend it 100% for anyone who wants serious power 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 honesty.
As for my PC, it’s the Savannah v2 with an RTX 5060 Ti and a Ryzen 7 5700x with 16GB RAM. It’s perfect for playing 1440p on high/ultra settings on big triple-A titles at 80/120 fps, and for esports up to 240fps on low/high (depending on the games).

The AMD Ryzen 5 5600 is an attractive solution for mid-range PCs, suitable for gaming as well as photo and video editing, while maintaining excellent value for money.
With 6 cores and 12 threads, it delivers solid performance and positions itself just below the Ryzen 5 5600X in terms of price. The Ryzen 5600 adopts 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 switching support from PCIe 3.0 instead of 4.0.

It’s also well suited for streaming, multitasking, and content creation.
Compatible with socket AM5, it supports DDR5 and PCIe 5.0, ensuring high throughput with next-generation graphics cards and SSDs. Its balance of massive cache, high clock speeds, and energy efficiency makes it a premium choice to avoid CPU bottlenecks.
