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.

Buyers who put native 12V-2x6 cable count first.

Skip if

Skip it if this is a deal-breaker for you: a 180mm depth needs a roomy PSU bay.

Why we like it

Thermaltake Toughpower GT 1000W

Lowest Price Here5 of 5

Thermaltake Toughpower GT 1000W on Amazon (opens in a new tab)

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

Spending as little as possible.

Skip if

Skip it if rated output matters most to you; the ASRock Phantom Gaming PG-1600G offers 1600W.

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 lowest in this group; the ASRock Phantom Gaming PG-1600G leads at 1600W. It matches the Seasonic PRIME TX-1600 Noctua Edition and the ASRock Steel Legend SL-1200G on native 12V-2x6 cable count (1).

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. It cost the least of the 5 picks at the time of writing, with the ASRock Steel Legend SL-1200G the next step up.

How We Chose

Each pick was assessed across 4 criteria weighted for real-world use.

Connectors
We recorded native 12V-2x6 cables and PCIe 8-pin connectors where the listing states them.
Wattage
We compared rated output with NVIDIA's or AMD's recommended system power for the card.
Standards
We noted ATX version, 80 Plus and Cybenetics ratings.
Price
We grouped picks by price at the time of writing.

What to Look for in a PSUs for Black Builds

Key buying criteria so you get the right fit the first time.

  1. Where these picks differ: rated output

    Among these picks, rated output runs from 1000W on the Thermaltake Toughpower GT 1000W to 1600W on the ASRock Phantom Gaming PG-1600G. Match this to what you will actually do with it, then let price decide between the picks that qualify.

  2. Match the power connector

    Most RTX 40 and RTX 50 cards use a single 16-pin 12V-2x6 (12VHPWR) plug, while many Radeon cards use two or three 8-pin plugs. A native cable avoids bulky adapters.

    Push the 16-pin plug fully home and avoid a sharp bend right at the connector.

  3. Compare efficiency ratings

    80 Plus and Cybenetics ratings describe how much power turns into heat. Gold is the usual target for a gaming PC; Platinum and Titanium run cooler and cost more.

  4. Check depth and cabling

    Deeper units can clash with drive cages or front radiators. Fully modular cables make routing easier in tight cases.

  5. Use the warranty as a quality signal

    Long warranties of seven to twelve years show how long a maker expects a unit to last. A power supply often moves from one build to the next, so the warranty matters.

Frequently Asked Questions

Which pick leads on native 12V-2x6 cable count?

The ASRock Phantom Gaming PG-1600G, at 2. The Seasonic PRIME TX-1600 Noctua Edition follows at 1, while the Thermaltake Toughpower GT 1000W has 1.

Which pick costs the least here?

The Thermaltake Toughpower GT 1000W cost the least when we checked, and the Seasonic PRIME TX-1600 Noctua Edition sat at the top of the range. Prices move often, so check the current listing before buying.

Can I reuse the power supply from my old PC?

Only if it meets the card's wattage and connector needs and is still under warranty or in good health. Very old units lack modern connectors.

Is an ATX 3.0 power supply still fine?

Generally yes. ATX 3.1 mainly revises the connector to 12V-2x6 and relaxes some spike requirements; check your unit's cable is rated for your card.

Does a Platinum unit save much on electricity?

Only a little for most gaming PCs. The main gains are less heat and often a quieter fan.

Bottom Line

Our first pick is the ASRock Phantom Gaming PG-1600G, chosen for the most native 12V-2x6 cable count here (2). Look at the Seasonic PRIME TX-1600 Noctua Edition for a Noctua NF-A12x25 fan with a custom fan curve at the highest price in the group, the ASRock Steel Legend SL-1200G for a Cybenetics LAMBDA A noise certification and the ASUS TUF Gaming 1200W Gold for military-grade capacitors and chokes if those matter more to you.
