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 Flowup’s after-sales service was ultra efficient. They replaced my card the same day (a special shout-out to Mickael, who was really 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—trust me!
The after-sales service is really good. The replies and the support are fast, with kindness and genuine 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, it’s a great investment that I don’t regret. There’s a great after-sales service with quick answers and full of kindness. Honestly, I recommend it with my eyes closed. Thank you for your work, team! Thank you 1000 times <3
Tristan X.I ordered a custom PC on this site—I was very well guided regarding how I wanted to use it, but above all I got my money’s worth.
I contacted the after-sales service several times to get a few answers, and they were very quick to respond. I strongly recommend FlowUP for buying a PC.
PC ordered on Sunday, received 6 days later with no issues at all. Thank you, the FlowUP team. The PC is really incredible—no problems.
Héléna B.Great contact — they directly communicated a new quote! The follow-up and the after-sales service for picking up the PC on site are exemplary. Thank you, Nathanaël, for this professionalism!

I bought from flow up.
I recently purchased a PC assembled by Flowup and the experience is impeccable. The assembly is ultra neat (perfect cable management), the components are 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 high-end 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 would 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 at high/ultra settings on big triple-A titles with 80/120 fps, and for esports at 240fps in low/high quality (depending on the games).

The GeForce RTX™ 5070 Ti is a next-generation graphics card designed for smooth gaming in QHD Ultra and 4K. It features the latest technologies DLSS 4 and Multi-frame Generation up to 4X for spectacular performance and outstanding fluidity.
Perfect for multitasking, streaming, and content creation. A versatile, powerful card ready for excellence today as it is tomorrow.
The processor Core i7 14700KF is an ideal choice for building a gaming-focused PC, or for professional tasks in the creative field.
In games, its performance competes with the best competing alternatives, matching even the i9 13900K—making it compatible with very high-end graphics cards.
When it comes to applications, it also delivers excellent performance for video editing, streaming, and 3D.
The AMD Ryzen 5 5600 processor is an appealing solution for mid-range PCs, suitable for gaming as well as photo and video editing, while still offering 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 PCIe 3.0 support instead of 4.0.
