EVGA SuperNOVA 1600 P2 Power Supply Review

EVGA recently introduced its flagship power supply, the SuperNOVA 1600 P2. In addition to monstrous capacity, it also features 80 PLUS Platinum efficiency, promises top performance levels and offers silent operation in semi-passive mode.

Performance, Performance Per Dollar And Noise 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.

The 1600 P2 achieves a high overall score. However, it doesn't pass the 1600 G2, despite the 1600 P2's higher efficiency under light and normal loads. Nonetheless, the above performance graph doesn't take into account noise output. The SuperNOVA 1600 P2 performs much better than its Gold-rated sibling in this discipline, since the higher efficiency levels allowed for semi-passive operation and lower fan speeds overall.

Performance Per Dollar

The following graph may be the most interesting to many of you because it depicts the unit's performance-per-dollar score. We looked up the current USD 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 isn't available in the United States, we searched for it in popular EU shops, converting the listed price to USD (without VAT). Note that all the numbers in the following graph are normalized by the rated power of each PSU.

Noise Rating

The graph below depicts the cooling fan's average noise over the entire operating range of the PSU, with an ambient temperature between 28 and 30 degrees C.

For a 1.6kW unit, the 1600 P2 features very quiet operation. Super Flower does a good job in this area, managing to address the 1600 G2's biggest flaw, which was greater noise due to the lack of a semi-passive mode.

    Good review, but missing the hot box testing to see if this thing regulates and suppresses ripple at 50C as advertised.

    All tests were conducted at high ambient temperatures which during full load were above 47C. Only the Cross-Load tests were conducted at 28-30C.

    Very detailed review indeed. There isn't really anything that could be covered and it is not. I don't think that there are many PSU manufacturers out there that can test their products so extensively.

    Too light for me I have the 2000w coming from Dabs when it comes to retail.

    I had the opportunity to test the 2 kW model (from Super Flower) and it is indeed superb. But it will provide 2 kW only with 230 VAC input since a normal socket can deliver only up to 15 A of current.

    Where are you from that you need all that power? Cybertron?

    47C ambients? Must have been sweating your language, please off, or you are language, please me.

    I'm going to power my Skynet build with it.

    One day you need to show us a picture of everything. I've seen little snapshots here and there, but I'd like to see it all in one thread.
