Jeremy Q.TOP-NOTCH AFTER-SALES SERVICE!
I received my PC with a faulty graphics card. The after-sales service from FlowUP was incredibly efficient. They replaced my card the same day (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 gentler than my bed. And yet I love my bed—honestly, believe me!
The after-sales service is genuinely high quality. The responses and the help provided are quick, with kindness and a real human touch.

Tristan X.great discovery...
I bought a made-to-measure PC on this site and I was very well guided according to the use I wanted to make of it, but above all I got my money’s worth.
I contacted the after-sales service (SAV) 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’ve recently bought a PC assembled by Flowup and the experience has been impeccable. The build is ultra tidy (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 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 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 AAA titles with 80/120 fps, and for esports at 240fps on low/high quality (depends 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 an excellent price-to-performance ratio.
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 close 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 9 9900X3D
The AMD Ryzen 9 9900X3D is a high-end processor aimed at intense gaming and advanced productivity, thanks to the combination of the Zen 5 architecture and 3D V-Cache, which frequently boosts in-game performance when the CPU becomes the bottleneck. It’s built on the AM5 platform and supports DDR5 as well as PCIe 5.0, with a 12-core / 24-thread configuration designed for streaming, video editing, and multitasking.
In a very brief comparison, the Ryzen 9 9950X3D stands out mainly for having more cores, which gives it a clearer advantage in heavily multithreaded workloads (rendering, encoding, computing), while the 9900X3D keeps a more balanced approach focused on gaming performance and versatility.
Memory :
- 4 slots DDR5
- Up to 192 GB – Max frequency 8000+ MHz (OC)
Storage :
- 4 x M.2 NVMe, including 1 compatible with PCIe 5.0
- 4 x SATA 6 Gb/s ports
PCIe ports :
- 1 x PCIe 5.0 x16
- 1 x PCIe 4.0 x16
- 1 x PCIe 3.0 x1
USB :
- 1 x USB 3.2 Gen 2x2 Type-C (rear)
- Multiple USB 3.2 Gen 2 / Gen 1
