Performance, Value, Noise & Efficiency
The following graph shows the SX800-LTI's total performance rating, comparing it to other units we have tested. To be more specific, the tested unit is shown as 100 percent, and every other unit's performance is shown relative to it.
The SX800-LTI is the best-performing SFX-L PSU we've tested. Naturally, it takes the lead from competing SFX units.
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.
Most SFX-L and SFX units are expensive, and the SX800-LTI is surely no exception. Given its high price, we didn't expect a particularly strong value score.
The graph below depicts the cooling fan's average noise over the PSU's operating range, with an ambient temperature between 30°C and 32°C (86°F to 89.6°F).
The fan profile is fairly aggressive, likely due to this PSU's high power density. But we think Enhance could probably loosen it a bit thanks to high efficiency. It probably just wanted to stay on the safe side.
The following graph shows the PSU's average efficiency throughout its operating range, with an ambient temperature close to 30°C.
Overall efficiency is almost the same as Lian Li's PE-750, which is based on the same platform. That model's maximum capacity is just a little bit lower, though.
