Are cheaper 850W units like the MSI MAG A850GL safe for a high-end GPU?

Mainstream reviewers and verified testing describe units like the MSI MAG A850GL as efficient and reliable for mainstream and mid-high builds, though specialist communities note they use more cost-cut internals than premium RMx-class units. For a very expensive flagship GPU, several high-trust community threads suggest stepping up to an A-tier unit for extra margin, but the budget picks are widely considered safe within their rating.
