EVGA SuperNOVA 1600 P2 Power Supply Review

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.
  • Aris_Mp
    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.
  • SinxarKnights
    I appreciate the detailed review.
  • Giannis Karagiannis
    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.
  • Aris_Mp
    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.
  • Dark Lord of Tech
    I'm starting a white and black build , a Snow Beast , next week.
  • damric
    With the Krait motherboard? Or is there another white/black?
  • Dark Lord of Tech
    No way this one.

    The PSU is inside a special-made box (hot-box) for the high temp tests.
  • Dark Lord of Tech
    Sweet board going to order it on monday.

    Wouldn't your FLIR show that the box is hot?
  • Aris_Mp
    no point since the box is insulated so from the outside the temperature will be lower. Also if i open the lid to take a snapshot with FLIR the temperature will drop immediately by 5 C at least (ambient) messing with the test.

    I already know what happens inside the box thanks to two temperature probes I have installed in it, so no need to use my FLIR on it. However on next review I will try it.

    Fair enough. It will be excellent when Tom's Hardware adopts a consistent review standard. Yours was one of the best PSU reviews yet. There's other nitpicks I have but they are nothing major like chart/graph formats could be easier to read.

    In your opinion everything held up in close to 50C conditions then?
  • loki1944
    Nice, if I ever go 3-4 way SLI I'll upgrade to this from my 1300W G2.

    Dont forget the OFF switch. Arnold is a busy man.
  • Aris_Mp
    "In your opinion everything help up in close to 50C conditions then?"

    around 45C is much more realistic. 50C are too much for modern chassis. However when needed I crank up the heat inside my hot box to see how the PSU performs. Like in this case that I deliberately exceeded my usual 45C and went to almost 48.

    The "Power Specifications" table on the second page is wrong. The third line must be "Maximum Watts" and not "Maximum Volts". Moreover, the Wattage calculation for the 3.3V rail is missing (should be 3.3*24 given that the maximum amperage for the 3.3V rail is 24A, this must be verified). The value 120 (W or VA) must be for the 5V rail since 5V*24A=120 VA/W...

    Also note that I'm making a distinction between Watts (W) and Volt-Amperes (VA) although they have the same dimension. The reason is this:

    I hope you do the same.

    The max power is the combined max power that both rails can deliver. Hence while each rail can go up to 24 A both of them can deliver only up to 120 W (combined). This means that either the 5V rail can go up to 120 W alone (so zero W for the 3.3V one) or the 3.3V rail can go up to 24 A and the 5V at 8.16 A.

    In DC we use Watts. VA is for AC. In DC Watts = VA

    As for the max voltage yeap this will be fixed.
