    Am I being overly cynical by suspecting the real reason for this is that by moving the 5-15W used by the cooling fan from internal to the PSU to something powered by the PSU (converting it from a loss counting against efficiency to part of the load being supplied) it lets them slap a platinum badge on a set of what would otherwise only be gold hardware?

    You really think a fan holds gold PSUs back from being Platinum? I don't think a fan uses even 5W, and what you listed is what a HDD uses. Adding one more harddrive isn't going to drop a Platinum PSU to a gold one.

    Testing here's shown a number of allegedly platinum PSUs falling short by 0.5-1%; which is 6-12W on a 1200W unit.

    I did a bit of quick searching after reading your comment and found 140mm fans at 2-7W; about half what I'd assumed. I'm pretty sure I've got some 120mm ones that are rated for higher power draw than that in my parts box at home (will check later tonight). Are newer fans more efficient than older ones, or am I mis-remembering?

    I have 3 120mm fans that only consume .5A or 6W total (so 2W each). And they are in the 1000 - 1500 rpm range. If you go for some Delta 5k rpm units, they can draw quite a bit. But I rarely see normal 120 / 140 mm fans that are over .4A on their own.

    I dug through my parts box of mostly old bundled case fans (I bought a 60mm delta screamer 16 years ago but at some point apparently got rid of it); and it does look like my memory was a bit off. I didn't find any 120mms above 0.6A (at one point I had 5 or 6 of these though), most were 0.3 to 0.4A. looking at the rest, about half of my 60-80mm collection were above 0.2A with a few above 0.3A. OTOH most of these are much older fans (10+ years); so either fans have gotten more efficient over the years or my assumption that power used would scale with size/airflow is wrong.

    I wasn't really convinced by a 1200 W Liquid-Cooled PSU. But then I saw it has RGB LEDs. I'm sold.

    LOL. MOAR LEDS!

    Koolance, Aqua Computer and SilentMaxx both made it to the market but people were too scared to use a liquid cooled power supply unit.

    This is the Koolance 1700w model: http://koolance.com/1300-1700w-liquid-cooled-power...
    The SilentMaxx can be seen via Google on Amazon and specialist watercooling stores (EOL)

    I definitely dont want the heat of a 1200w PSU being dumped into my Watercooling loop.
  • 4745454b - Friday, June 2, 2017 - link

    Why not? It's not dumping 1200W of heat energy into the loop. While not exact, you are only getting the conversion loss dumped into the loop. And because it's a Platinum PSU it's not going to be a lot. Yes it will be more energy than just the CPU and GPU for your loop to handle, but it's not going to be 1.2kW more.

    If you actually need a PSU this big it's still a lot. Give or take voltage requirements at full load it's 90% efficient; so you'd be adding ~120W. At half load it's only ~40W; but if you only need 600W this isn't the right PSU for you.

    Actuallif you need 600-650W this is the perfect PSU for you since optimal efficiency sits around 50-60% of the max power.

    * water cooled STRIKE ONE!
    * LEDs STRIKE TWO!
    * Fortran STRIKE THREE!

    YER OUT!
