The right gaming power supply depends on the graphics card. High-end cards need 1000W or more and a native 12V-2x6 cable; mid-range cards run on 650W to 850W.
We compared wattage, connectors, depth and warranty from each listing; we did not test these units.

Why we like it
It has a native 12V-2x6 cable and braided ribbon cables. It matches the Rosewill VMG 850W on rated output (850W). It matches the MSI MAG A750GL PCIE5, the Rosewill VMG 850W and the Seasonic CORE GX-650 on native 12V-2x6 cable count (1).

How We Chose These Gaming Power Supplies
Alex Morgan compared the manufacturer specifications, connectivity, warranty terms and compatibility of every pick. Figures come from the makers unless a third-party source is named; we did not test these products ourselves.
- What we compared
- We set side by side five power supplies on rated output, native 12V-2x6 cable count, warranty and 80 Plus rating, using each maker's published specs. We did not test them in-house, and warranty and 80 Plus rating are missing for at least one pick.
- What every pick has in common
- All 5, from the MSI MPG A1000GS PCIE5 II to the Seasonic CORE GX-650, state rated output, native 12V-2x6 cable count and form factor and share Black colour.
- Where the specs have gaps
- The Super Flower Leadex VIII Platinum PRO 850W and the Seasonic CORE GX-650 give no warranty; the Super Flower Leadex VIII Platinum PRO 850W gives no 80 Plus rating.
- Price range
- At our last check the picks ran from the Rosewill VMG 850W ($50 to $100) to the Super Flower Leadex VIII Platinum PRO 850W ($100 to $150).
