### ⭐⭐⭐⭐⭐ Review
*by R***C on 12 October 2025*

Très bonne alimentation ATX en terme de rapport qualité/prix. Fabriquée par CWT (Channel Well Technologies), un fabriquant OEM bien connu pour la qualité de ses produits, cette alim ne déroge pas à la règle. On est bien sûr pas sur du haut de gamme comme sait aussi le faire CWT mais plutôt sur du moyen de gamme bien fait avec des concessions ici et là mais au final de très bonnes tensions en sortie et une qualité globale honnête. Notons la présence d'un bon gros monorail de sortie en +12V de 45.5 Ampères soit 546W. Les câbles plats bien que inamovibles (ce n'est pas une alim modulaire) facilitent le cable management lors du montage. Un produit que je recommande dans cette catégorie de prix.
