Why you can trust Tom's Hardware
Performance, Value, Noise & Efficiency
The following graph shows the SSR-1000PD Ultra'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.
Seasonic's new Ultra 1kW platform offers better performance than its predecessor, which was already among the best in this category. Naturally, then, the SSR-1000PD Ultra takes the crown.
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 price tag is fair, so Seasonic's SSR-1000PD Ultra achieves a good (but not great) 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).
This is not the quietest 1kW PSU. However, as you can see, it seriously improves on the previous generation's acoustic performance.
The following graph shows the PSU's average efficiency throughout its operating range, with an ambient temperature close to 30°C.
The overall efficiency of our sample is a little lower than the SSR-1000PD we measured previously. That difference is very small, though. A second sample could fare better (or worse, for that matter).

I notice you didn't give it an award rating...what gives, if you present it with such high praise?Reply
It has an award. It is just not shown, yet :)Reply
Lets all hope it doesn't kill your motherboard and all components like my SeaSonic did while only operating 1 year under light workloads. No matter how much change they make to PSU I would not trust a brand that would allow catastrophic results in using their products AND not accept responsibility for the loss.Reply
