Very positive review, 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. FlowUP’s after-sales service was extremely effective. They replaced my card the very same day (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 feels softer than my bed. And yet I love my bed—trust me!
The customer support is genuinely high quality. The responses and the help provided are fast, with kindness and real human interaction.
Order received in 5 days (weekend included)

Tristan X.I bought a custom PC on this website. 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 customer 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 with no issues at all. Thank you to the FlowUP team.
The PC is really incredible—no problems.

I bought from Flow Up.
I recently purchased a PC assembled by Flowup, and the experience is faultless. The build 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 impeccable condition. I recommend it 100% for anyone who wants a beast of a PC 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 at 1440p in high/ultra quality on big triple-A titles with 80/120 fps, and for esports at 240fps in low/high settings (depending on the games).

The GeForce RTX™ 5070 Ti is a next-generation graphics card designed for smooth QHD Ultra and 4K gaming. It integrates 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 that’s ready to excel today as well as 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 the best competing alternatives, even reaching the level of the i9 13900K, making it compatible with very high-end graphics cards.
As for applications, it also delivers outstanding performance for video editing, streaming and 3D.
The AMD Ryzen 5 5600 processor is an attractive solution for mid-range PCs, suitable for gaming as well as photo and video retouching, 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 supporting PCIe 3.0 instead of 4.0.
