Very positive reviews, despite comments about delivery times, no problem on my side: the screen was dispatched the next day after my order and the PC arrived 3 days later.
Jeremy Q.Top-notch after-sales service!
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 (shout-out to Mickael, who was genuinely great).
Lenny N.No regrets!
I invested in the BlackHawk and it’s been a joy. With the Cooler Master MK770 keyboard and the MSI IMMERSE GH20 headset, it’s more comfortable than my bed. And yet I love my bed—believe me!
The after-sales service is genuinely great. Replies and help are fast, with kindness and a real human touch.
Awesome 👍
Order received in 5 days (including the weekend)

Arnaud N.I bought the Savannah
Honestly, it’s a great investment that I don’t regret. There’s a great after-sales service with quick replies and lots of kindness. Honestly, I recommend it with my eyes closed. Thanks for your work, the team! Thanks a thousand times <3
Tristan X.Great discovery...
I bought a custom PC on this site. I was guided really well regarding the use I wanted, but above all, I got my money’s worth.
I contacted the after-sales service several times to get some answers. They were very responsive, and I strongly recommend FlowUP for buying a PC.

I bought from flow up.
I recently bought a PC built by Flowup and the experience has been flawless. The build is extremely 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 them 100% for anyone who wants serious power without any 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 equipped with a RTX 5060 Ti and a Ryzen 7 5700x with 16GB RAM. It’s perfect for gaming at 1440p on high/ultra settings in big triple-A titles with 80/120 fps, and for esports at 240fps on low/high settings (depending on the games).

amd ryzen 5 5600
The AMD Ryzen 5 5600 processor is an appealing solution for mid-range PCs, suited to gaming as well as photo and video retouching, 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 supporting PCIe 3.0 instead of 4.0.

AMD Ryzen™ 7 9800X3D
The AMD Ryzen™ 7 9800X3D is a premium processor dedicated to high-performance gaming PCs, designed to maximise FPS and reduce in-game latency.

Featuring 8 cores / 16 threads and high clock speeds with dynamic boost, the Ryzen 7 9800X3D offers excellent responsiveness, more consistent FPS and fewer micro-stutters—ideal for competitive gaming, high-frequency 1440p and smooth 4K. It is also suitable for streaming, multitasking and content creation.
Compatible with socket AM5, it supports DDR5 and PCIe 5.0, ensuring high bandwidth with next-generation graphics cards and SSDs. Its balance of massive cache, high clock speed and energy efficiency makes it a premium choice to avoid any CPU bottleneck.
