Very positive reviews, despite comments about delivery time—no problems on my side: the screen was shipped the day after I ordered, and the PC arrived 3 days later.
Jeremy Q.I received my PC with a faulty graphics card, and the after-sales service from FlowUP was ultra effective. They replaced my card the very same day (big shout-out to Mickael, who was genuinely great).
Lenny N.I invested in the BlackHawk and it’s a pleasure. With the cooler master MK770 keyboard and the MSI IMMERSE GH20 headset, it’s softer than my bed. And yet I still love my bed—believe me!
The after-sales service is truly high quality. The responses and the help provided are quick, with kindness and a real human exchange.
Order received in 5 days (weekend included)
Very good condition, good price, and responsive, effective after-sales service.
I recommend it.
Arnaud N.Honestly, it’s a great investment that I don’t regret. There’s a fantastic after-sales service with quick answers and lots of kindness. Honestly, I recommend it without hesitation. Thank you for your work, team! Thank you 1000 times <3
Tristan X.I bought a custom PC on this site, and I was really well guided regarding 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 some answers. They were very responsive; I strongly recommend FlowUP for buying a PC.
PC ordered on Sunday, received 6 days later without any issues. Thanks to the FlowUP team.
The PC is really incredible—no problems at all.
Héléna B.Great communication: they sent a new quote directly! The follow-up and the after-sales support for picking up the PC on site are exemplary. Thank you, Nathanaël, for your professionalism!

I bought from Flow up.
I recently bought a PC built by Flowup and the experience is flawless. The build is ultra neat (perfect cable management), the components are high quality, and the performance is exactly what was advertised—if not better.
Special mention for the secure packaging: the PC arrived in immaculate 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 at 1440p in high/ultra quality on big triple-A titles with 80/120 fps, and on esports at 240fps in low/high quality (depending on the games).
