'''Question:'''  I need to power LOTS of NeoPixels and don’t have a power supply that large. Can I use several smaller ones?

'''Question:'''  J'ai besoin de BEAUCOUP de NeoPixels et je n'ai pas d'alimentation suffisamment puissante. Puis-je en utiliser plusieurs?

'''Maybe'''. There are benefits to using a single supply, and large power supplies are discussed below. “Non-optimal” doesn’t necessarily mean “pessimal” though, and we wouldn’t discourage anyone from using what resources they have.

'''Peut-être'''. Il y a des avantages à utiliser une seule et puissante alimentation (comme abordé ci-dessous). Ci ce n'est "pas optimal", celane signifie pas pour autant que ce n'est pas bon, nous ne voudrions pas vous décourager à utiliser les ressources à votre disposition.

If you go this route, the key is to have all of the ground pins among the strips connected in common, but the +5V from each power supply should be connected only to one length of NeoPixels — those should not all be joined. Every power supply is a little different — not precisely 5 Volts — and this keeps some from back-feeding into others.
