In a black build the PSU cables are the most visible part through the glass. Every pick is black and fully modular, so you fit only the cables you use, ordered by wattage.
The order reflects wattage, native 12V-2x6 cables and warranty from maker specifications; a missing native 12V-2x6 cables is flagged, not filled in rather than guess, since we have not benched them.

Skip if
- Skip it if this is a deal-breaker for you: a 180mm depth needs a roomy PSU bay.
Why we like it
At 180mm deep it needs a large case. It matches the Seasonic PRIME TX-1600 Noctua Edition on rated output (1600W). On native 12V-2x6 cable count it leads this guide at 2, ahead of the Seasonic PRIME TX-1600 Noctua Edition (1).

How We Chose
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.

- How these picks were ranked
- We set side by side five power supplies on rated output, native 12V-2x6 cable count, warranty and depth from manufacturer specifications. Nothing was tested in-house; 6 of the 12 fields compared are stated for every pick, while native 12V-2x6 cable count and warranty have gaps.
- What every pick has in common
- All 5, from the ASRock Phantom Gaming PG-1600G to the Thermaltake Toughpower GT 1000W, state rated output, 80 Plus rating and ATX version and share ATX 3.1 ATX version and Fully modular cabling.
- Where the specs have gaps
- The ASUS TUF Gaming 1200W Gold gives no native 12V-2x6 cable count; the Seasonic PRIME TX-1600 Noctua Edition and the Thermaltake Toughpower GT 1000W give no warranty.
- Price range
- At our last check the picks ran from the Thermaltake Toughpower GT 1000W ($50 to $100) to the Seasonic PRIME TX-1600 Noctua Edition ($500 to $1000).
