Very positive reviews, despite comments about delivery time—no issues on my side: the screen was shipped the 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 (big shout-out to Mickael, who was really great).
Lenny N.I invested in the BlackHawk and it’s a joy. 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 truly high quality. The responses and the help provided are fast, with kindness and genuine human interaction.
Order received in 5 days (weekend included)

Tristan X.I ordered a custom PC on this site. I was very well guided based on how I wanted to use it, but above all, I got my money’s worth.
I contacted the after-sales service (SAV) several times to get some answers. They were very responsive. I strongly recommend FlowUP for buying a PC.
PC ordered on Sunday, received 6 days later without any issues. Thank you to the FlowUP team. The PC is truly incredible—no problems at all.
Héléna B.Great contact: they communicated a new quote to me straight away! The follow-up and the after-sales service for picking up the PC on site are exemplary. Thank you to you, Nathanaël, for your professionalism!

I bought from Flow up.
I recently purchased a PC built by Flowup and the experience is flawless. The assembly is ultra clean (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 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 sincerity.
As for my PC, it’s the Savannah v2 with an RTX 5060 Ti and a Ryzen 7 5700x with 16GB rap. Perfect for playing in 1440p at high/ultra quality on big triple-A titles with 80/120 fps, and for esports at 240fps in low/high quality (depending on the games).

Its role in the setup
The GeForce RTX™ 5070 Ti is a next-generation graphics card built for ultra QHD gaming and smooth 4K. It features the latest technologies DLSS 4 and Multi-frame Generation up to 4X for spectacular performance and exceptional smoothness.
Perfect for multitasking, streaming and content creation. A versatile, powerful card—ready to excel today as it will tomorrow.
The processor Core i7 14700KF is an optimal choice for building a gaming-focused PC, or for professional tasks in the creative field.
In gaming, its performance matches up with the best competing alternatives, even equalling that of the i9 13900K—making it compatible with very high-end graphics cards.
For 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 maintaining 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 PCIe 3.0 support instead of 4.0.
