Power supply (PSU)

Good7.5/10Mid-range

MSI has become a credible PSU brand, with its MAG A-GL range often recommended as a cheap, modern Gold unit. Higher-end MPG and MEG models are good too. Avoid the budget Bronze series unless the build is very modest.

Good at

  • MAG A-GL units are strong value ATX 3.x picks
  • Yellow-tipped 12V-2x6 plugs show when fully inserted
  • High-end MEG Ai models add power monitoring

Weak at

  • Budget MAG A-BN models are only average
  • Quality depends on which OEM built the series
  • RMA experience varies by region
