Frequently asked questions

In our “Frequently asked questions” section, you’ll find all the essential information about our services, ordering your gaming PC, payment options, delivery, and much more.

WHAT ARE THE DELIVERY LEAD TIMES?

In general, we plan a shipping lead time of 5 to 7 working days (excluding weekends) to process orders.

However, for custom PC orders, these lead times may vary, because we have to source components that aren’t in stock, which can extend the shipping time.

We’re committed to keeping you informed about the estimated delivery lead times, so you can plan accordingly.

What is custom watercooling?

Custom watercooling is a liquid cooling system designed specifically for computers.

Unlike pre-assembled liquid cooling solutions, custom watercooling allows a modular setup, integrating elements such as pumps, reservoirs, tubes, and radiators—tailored to the customer’s requirements and the architecture of their case.

This type of system is particularly effective at maintaining optimal temperatures, even during overclocking, while offering a refined look thanks to transparent tubes and coloured liquids.

CAN I MODIFY A PC FROM THE SITE?

Of course! We’d be happy to offer a custom assembly service so you can personalise your PC configurations according to your preferences.

Depending on our stock, we’d be happy to help you change certain components such as the case, graphics card, processor, and many more.

really top—just be patient
My laptop was at the end of its life, so I needed to replace it with a desktop computer this time. However, since I know nothing about PC building, several friends recommended FlowUp. So I went to their custom PC section, and I was connected with Nathanael, who replied quickly and advised me perfectly based on my needs.
A very good after-sales service as well—Nathanael contacted me several times to ask whether my delivery went well, whether my machine was working properly, advice, etc…
To everyone who wants the PC of their dreams—go for it! Don’t hesitate; just be patient depending on what you want!

I have only one thing to say: go for it! A custom PC, truly made for gaming, and on top of that great after-sales service with a technician who is just as good. I had 0 issues with the PC I bought on the site.

PC Orion
I was taken care of by Nathanael when purchasing the Orion PC.
Order placed on 7/11 and received on 14/11.
Nathanael was very professional and reassuring. He answers all questions by e-mail or phone as soon as possible.
The PC is expensive, but once I received it, I really felt like I got a high-quality product.
Sure, you can find something slightly cheaper in Germany or by building your own PC, but with FlowUp you get the convenience of plug and play and impeccable customer service.

flowup 👌
Hello everyone! A short while ago I placed an order with FlowUP for a gaming PC. I must admit that I was pleasantly surprised right away by their customer handling: human, attentive, and custom; not to mention the prices that were surprisingly better than the competition.
On top of doing everything as quickly as possible in a professional manner, they also know how to handle unexpected situations. I had the misfortune of receiving a factory defect on a part of the computer; their responsiveness and handling were optimal, because besides their quick turnaround time and expertise, they don’t leave you like that—every step is explained, and if necessary they take time for you. A big thank you to Benjamin, Alexandre, Mik or Mickael—sorry, bad memory—and to the whole team!!! This is a big investment and I’m happy I made it with you. Thanks again!
