Super Flower Leadex Titanium 1000W PSU Review
Super Flower was one of the first companies to release an 80 Plus Titanium-rated PSU. Following the ultra-high-capacity SF-1600F14H unit, the company released two more Titanium PSUs, one of which we're evaluating today.

Performance, Performance Per Dollar, Noise And Efficiency Ratings
Performance Rating
The following graph shows the total performance rating of the PSU, comparing it to other units we have tested in the past. To be more specific, the tested unit is shown as 100 percent, and every other unit's performance is shown relative to it.
Thanks to its extraordinary efficiency, the SF-1000F14HT takes first place in the 1kW category's relative performance chart. Mediocre ripple suppression on the 3.3V rail is what brings it closer to the Leadex Platinum platform and Corsair RM1000i. If Super Flower finds a way to improve performance on the 3.3V rail without affecting the unit's efficiency, then the Titanium Leadex will defend its position much easier against future contenders with similar capacity and efficiency.
Performance Per Dollar
The following chart may be the most interesting to many of you because it depicts the unit's performance-per-dollar score. We looked up the current price of each PSU on popular online shops and used those prices and all relative performance numbers to calculate the index. If the specific unit wasn't available in the United States, we searched for it in popular European Union shops, converting the listed price to USD (without VAT). Note that all of the numbers in the following graph are normalized by the rated power of each PSU.
The small performance difference, combined with a lofty price, hurts Super Flower's placement in this chart. Again, Titanium-class efficiency is hard to achieve, necessitating expensive parts and a sophisticated production line. Don't expect the prices of Titanium-rated PSUs to drop any time soon.
Noise Rating
The graph below depicts the cooling fan's average noise over the PSU's entire operating range, with an ambient temperature between 28 and 30 °C (82 to 86 °F).
The Platinum Leadex proved to be quieter than the Titanium PSU, thanks to its more relaxed fan profile. Super Flower probably chose a safer approach for its flagship 1kW unit. Though the SF-1000F14HT operates quietly, it cannot match Corsair's offerings in this market segment.
Efficiency Rating
The following graph shows the average efficiency of the PSU throughout its entire operating range, with an ambient temperature between 28 and 30 °C.

The SF-1000F14HT even manages to outperform Corsair's mighty AX1500i in the efficiency chart. Only the 1.6kW version of the same platform achieves higher efficiency. Against Platinum-rated FSP and Rosewill offerings of similar capacity, the Leadex PSU achieves a >1 percent difference.

Some might be, but generally, don't expect interchangeable cables. There are many different implementations for the connectors for one reason or another. -
Aris_Mp ReplyAre modular cables interchangeable between the different power supply vendors or will this happen in the future.
It highly recommended to assume that they are not, even when the PSU is made by the same manufacturer.

Aris_Mp ReplySo, ah, what did you use as a price?
We used the price sold in EU stores, excluding the VAT of course. -

Which is? I looked and saw a price of 200 euro. That's about $220. Does it include VAT? -

My gosh! I just want to know in dollars what your estimated price was!

Andi lim Using a bunch of KRG series capacitor for extra suppress ripple in Titanium PSU ?Reply
The Analogy : you want to build a super car, lets say Nissan GTR, but at the end you decide to use some cheap parts from Datsun on to your car, hahahaha.
The Question is, How long this PSU will stay in titanium level efficiency ?
Let's say after a year usage, the standard and cheap KRG capacitor will slowly increace the ESR, leak current dan temperature. at that time, this PSU efficient will go to platinum level or below ? Only time will tell.
