Very positive reviews, despite comments about delivery times: no issues on my side. The screen was shipped the day after I ordered and the PC arrived 3 days later.
Jeremy Q.I received my PC with a faulty graphics card. FlowUP’s after-sales service was ultra effective. They replaced my card the same day (dedicated shout-out to Mickael, who was really great).
Lenny N.I invested in the BlackHawk and it’s pure 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 really high quality. Responses and help are fast, with kindness and genuine human interaction.
Order received in 5 days (including the weekend)
Very good condition, good price, and responsive and efficient after-sales service.
I recommend it.

Tristan X.I bought a custom PC on this site. I was very well guided based on the use I wanted to make of it, but above all, I got value for my money.
I contacted the after-sales service 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 with no issues at all. Thanks to the FlowUP team. The PC is really incredible—no problems at all.

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 perfect condition. I recommend it 100% for anyone who wants top-tier 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.
About my PC: it’s a Savannah v2 equipped with an RTX 5060 Ti and a Ryzen 7 5700x with 16GB rap. It’s 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).

The GeForce RTX™ 5070 Ti is a next-generation graphics card designed for Ultra QHD gaming and smooth 4K. It incorporates 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 ideal choice for building a gaming-focused PC or for professional tasks in the creative field.
In gaming performance, it competes with the best competing alternatives, even matching that of the i9 13900K, making it compatible with very high-end graphics cards.
As 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 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 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 L3 cache to 16 MB and PCIe 3.0 support instead of 4.0.
