Super Flower Leadex Titanium 1700W Review 

Top Performance

In 2023, I reviewed the Super Flower Leadex Titanium 1600W ATX v3.0, a descendant of the platform behind the EVGA SuperNOVA T2/P2/G2 1600 units. In 2025, I tested the much stronger Leadex 2800W. The Leadex Titanium 1700W is the new flagship for systems with either 115V or 230V input. It accepts 115-240V, while its 2200W and 2800W siblings require 230V.

The black, fully modular chassis measures 150 x 85 x 200mm. It weighs 2.86 kg. It’s 25mm shorter than the older Titanium 1600W, although you’ll still need a case with enough PSU clearance. The side panels carry the “LEADEX ATX 3+” print. A 140mm ZIC ZFB142512D double ball bearing fan provides cooling, with an AUTO/ECO switch on the modular panel. I tested in semi-passive mode.

Super Flower specifies ATX 3.1 and PCIe 5.1 support, and the unit carries the Cybenetics ATX v3.1 label. Two native 12V-2×6 cables are rated for 600W each. You also get two EPS connectors and six PCIe 6+2-pin connectors, each with a separate cable. Sixteen SATA and four Molex connectors cover peripherals. All cables can be connected at once, thanks to the 18 modular sockets. The C20 inlet takes a C19 power cord, and the input label rates the unit at 17A with 115V.

The Cybenetics evaluation awards Titanium efficiency at both input voltages: 91.791% at 115V and 93.542% at 230V. Average noise output is 24.72 dB(A) at 115V and 23.58 dB(A) at 230V, earning LAMBDA A ratings at both voltages.

Super Flower manufactures the platform in-house, using bridgeless APFC, a full-bridge LLC resonant converter, synchronous rectification on 12V, and DC-DC converters for the minor rails. The bulk capacitors come from Nippon Chemi-Con, and Super Flower specifies Japanese 105°C capacitors on the main board. The warranty lasts 10 years.

At $429.99 on Amazon.com (November 12, 2026), the Leadex Titanium 1700W joins a comparison of 22 PSUs spanning 1500W to 1700W. Its rivals include the ASRock Taichi TC-1650T, the Seasonic Prime Noctua Edition TX-1600, the be quiet! Dark Power Pro 14 IO 1600W, and the older Leadex Titanium 1600W.
