Verdict
ASUS ROG Strix 1000W Gold ATX3.0
8.2 / 10 Expert Rating
ASUS extends the Strix Gold ATX3.0 line to 1000W here, keeping the Aura Sync-lit fan shroud and Axial-tech blades from the 850W model while adding headroom for a higher-end GPU.
Corsair CX550M
6.9 / 10 Expert Rating
A safe, unglamorous budget Bronze pick for entry-level gaming PCs that don't need Gold efficiency or full modularity.
