Super Flower Leadex Titanium 1600W Power Supply Review

Corsair's mighty AX1500i PSU must now face some stiff competition, as Super Flower's new Leadex Titanium 1600W offers even more power and efficiency.

Titanium Efficiency At Premium Cost

Without a doubt, Super Flower created a winner in the Leadex Titanium PSU. This is the company's superb new platform, which is highly versatile, able to deliver a wide range of power (up to 2kW) with efficiency levels that meet the strictest (at least for the moment) 80 PLUS Titanium requirements. I believe that only Flextronics, with its amazing Corsair AX1500i, has something that can really surpass this new Leadex platform in overall performance. However, even that PSU's digital circuits lose in out to the Titanium Super Flower when it comes to efficiency. Instead, Flextronics achieves a better overall performance score.

The new Leadex Titanium PSU has many advantages and is currently the most efficient high-capacity PSU on the market. The engineers who built it clearly pushed the analog circuits to their limits in order to keep energy losses to a minimum. Doing this requires numerous testing hours, extensive knowledge and, of course, a good design.

All of the above, along with the quality components used, play into the high price that Super Flower is asking for this unit. After all, there are only two Titanium-rated products in this category, and the most efficient one is this Leadex PSU. It may lack the digital circuits that allow for software monitoring and control, but some could argue that in a PSU it is better to keep things as simple as possible. In my opinion, however, digital circuits are the way to go for even more efficient and higher-performing PSUs, since designs like the one used in this Titanium Leadex PSU are really difficult to improve any further.

Compared to the Platinum- and Gold-rated versions of this platform, the Titanium implementation had to make some small sacrifices in ripple suppression and load regulation to achieve higher efficiency levels. However, this didn't prevent this PSU from achieving high overall performance, which classifies it among the best PSUs that money can buy. If you're looking for similar capacity and a better performance per dollar ratio, then look to the Gold version of this platform. Also a terrific product, it is currently sold at a much lower price than its Platinum and Titanium siblings.

The Titanium Leadex has other downsides besides its high price. Take the huge dimensions and the noise that its fan makes once it is engaged if you select the semi-passive mode, for example. Also, you can't find this product anywhere in the U.S, disqualifying it from award contention.

    As much as these super powered PSU reviews are interesting, I wouldn't mind seeing more PSU's for the regular non 4-way Crossfire/SLI user. I think in July you guys did some 450W reviews? Wouldn't also mind a battle of the basement review for those cheap PSU's just for fun. Again, love these 1000+ Watt reviews, but maybe toss in some sub 600W stuff in there more often if possible. Love the depth you guys go to in your PSU reviews!

    Can you arc-weld aluminum with this?

    One lead from ground, the other on the 12v?

    The Power Supply failed 80 Plus Titanium specifications at 50% (93.34% vs 94%) and 100% (89.61% vs 90%)

    Page 9 graphs shows a different PSU (Corsair CS850M) though they all link to the correct full list images when clicked.

    80 PLUS certification occurs at 23°C only.

    Tom's Hardware is testing in a hotbox at over 42°C. So how is that failing 80 Plus Titanium specifications when 80 PLUS Organization doesn't certify or even test at that temperature?

    Kitguru.net measures efficiency at 35°C and the SuperFlower Leadex Titanium 1600W has no problem meeting 80 PLUS Titanium:

    i personally cant see a reason to go lower than 650 watts, the most basic computer with a gpu may only use 50-60% of it at load, but the head room is valued by me far more than the cheaper outset cost...

    i had a psu blow up on me... never again.

    The next PSUs will be more down to earth, with sub-1000 W capacities

    Already informed the editors responsible to fix this. Thanks!
