Verdict
ASUS ROG Loki SFX-L 1000W Platinum
8.7 / 10 Expert Rating
The 1000W Loki SFX-L is the halo SKU of ASUS's small-form-factor line, aimed at ITX builders who want to run a flagship GPU without moving up to a full ATX case.
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.
