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 ultra effective. They replaced my card the same day (big 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 truly high quality. The replies and the support are fast, with care and real human interaction.
Order received in 5 days (weekend included)
Very good condition, good price, and responsive and efficient after-sales service.
I recommend it.
Arnaud N.Honestly, it’s a great investment that I don’t regret. There’s a great after-sales service with quick responses and lots of kindness. Honestly, I recommend it without hesitation. Thanks for your work, the team! Thank you 1000 times <3
Tristan X.I bought a custom PC on this site and I was very well guided based on how I wanted to use 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, and 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.
Héléna B.Great contact: they communicate a new quote directly! The follow-up and the after-sales service for picking up the PC on site are exemplary. Thank you to you, Nathanaël, for your professionalism!

I bought from Flow up.
I recently bought a PC assembled by Flowup and the experience is impeccable. The build 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 pristine condition. I recommend it 100% for anyone who wants serious 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’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 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 AMD Ryzen 5 5600 is an attractive option for mid-range PCs, suited for gaming as well as photo and video editing, 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 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.
