GoKawiilThere is no real competition for the Leadex 2800W. It is the most powerful retail power supply unit currently available, and it performs exactly as the specifications suggest. Super Flower has built a reference-class unit with premium components throughout, an exceptional topology, and efficiency numbers that embarrass units half its capacity. The price is what it is, and the target buyer is not negotiating.

Super Flower Computer Inc. is a Taiwanese company founded in 1991, headquartered in the Xinzhuang area. Over more than three decades, Super Flower has built a reputation grounded in engineering rather than marketing. For much of its history, the company operated largely out of public view in Western markets, functioning as the OEM behind some of the most respected power supply lines ever sold under other brand names. The entire EVGA G2, G3, P2, and T2 series were Super Flower designs, and those units earned a loyal following built entirely on real-world performance. When the commercial relationship with EVGA ended, Super Flower gained the freedom to sell under its own name in North America and Europe, and the Leadex series has been the vehicle for that transition.
The Leadex 2800W is what happens when that engineering pedigree is applied without compromise or cost constraint. It is an ATX 3.1 compliant unit rated at 2800 watts continuous output, and it carries a Cybenetics Titanium certification at the time of this review. It is designed to operate on 200 to 240 VAC input, which is worth addressing directly: the unit will function at 115 VAC, but practical output is sharply limited under that condition, as a standard North American outlet cannot supply more than approximately 1800 watts, capping usable PSU output at around 1700 watts. Anyone intending to operate this unit at anything near its rated capacity must use a 200 to 240 VAC supply, which requires a special outlet installation in the US. This is not a product for a typical desktop. It targets workstation and extreme gaming builds where power demands exceed what any conventional unit can supply. It's one of the best power supplies we've tested.
