Fully modular cabling is now common on budget units. Every pick is fully modular and cost $100 or less, ordered by wattage.
We ranked these power supplies on wattage, native 12V-2x6 cables and warranty using manufacturer specifications; we did not test these power supplies ourselves, and where a maker leaves out warranty, we say so.

Our Picks
Highest Rated Output1 of 5
Thermaltake Toughpower GT 1000W
Thermaltake's Toughpower GT 1000W is only 140mm deep, short for its wattage, and ships with a native 12V-2x6 cable and flat modular cables.
Best for
- Buyers who put rated output first.
Skip if
- Skip it if you need to know its warranty before buying; the maker doesn't publish one.
Why we like it
Its flat modular cables have colour-matched connectors, and a hydraulic-bearing fan with Smart Zero Fan keeps it quiet. Its 1000W rated output is the highest here; the darkFlash DG850 comes next at 850W. It matches the darkFlash DG850 on depth (140mm).
The Thermaltake Toughpower GT 1000W comes with a native 12V-2x6 cable, so a 16-pin card plugs in without an adapter. At 140mm deep, compare it with your case's PSU clearance before buying. At our last price check it topped the group, with the MSI MAG A750GL PCIE5 the nearest cheaper option. If you want a confirmed warranty, look to the ASRock Steel Legend SL-850GW White instead: it offers 10 years, while this one gives no figure.
