Very positive reviews, despite comments about delivery time—no issues on my side at all. The screen was dispatched the next day after my order, and the PC arrived 3 days later.
Jeremy Q.Customer service—top notch!
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.No regrets!
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. Responses and help are fast, with kindness, and you get a real human exchange.

I ordered a made-to-measure PC on this website; I was really well guided according to 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; they were very responsive. 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 impeccable. The build is super 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 something high-end without any hassle!Experience date: 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 RAM. It’s perfect for gaming in 1440p at high/ultra settings on big triple-A titles with 80/120 fps, and for esports at 240fps in low/high settings (depending on the games).

amd ryzen 5 5600
The AMD Ryzen 5 5600 is an attractive solution for mid-range PCs, suitable for gaming as well as photo and video editing, while still delivering an excellent price-to-performance ratio.
With 6 cores and 12 threads, it offers solid performance and sits just below the Ryzen 5 5600X in terms of price. The Ryzen 5600 uses a chiplet design with 32MB 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 16MB and supporting PCIe 3.0 instead of 4.0.

AMD Ryzen 99900X3D
The AMD Ryzen 9 9900X3D is a high-end processor designed for intense gaming and advanced productivity thanks to the combination of the Zen 5 architecture and 3D V-Cache, which frequently improves in-game performance when the workload is limited by the CPU. It is built on the AM5 platform and supports DDR5 as well as PCIe 5.0, with a configuration of 12 cores / 24 threads suited to streaming, editing and multitasking.
In a very brief comparison, the Ryzen 9 9950X3D stands out mainly thanks to its higher number of cores, giving it a clearer advantage in heavily multithreaded workloads (rendering, encoding, calculations). Meanwhile, the 9900X3D maintains a more balanced, gaming-focused approach with versatility.
