FSP this week has announced that its Hydro PTM+ 1200 W/1400 W power supply, featuring a liquid cooling block that was originally demonstrated at Computex 2017, would hit the market shortly. Priced at nearly $700, the PSU has a significant additional cost. To soften the blow for early adopters, the first 500 buyers will get a free Bitspower AIO LCS kit along with sleeved cables.

The FSP Hydro PTM+ PSU is compliant with the ATX12V v2.4 as well as EPS12V v2.92 standards and is rated for a 100 A maximum load and 1200 W power. The power supply is certified for the 80Plus Platinum badge at 1200 W when it is cooled down using its built-in 135-mm fan, but once it is connected to a liquid cooling system, the manufacturer guarantees that it can handle loads of up to 1400 W. The liquid cooling block of the FSP HPT1200M was developed by Bitspower and is compatible with various custom-built liquid cooling systems from different manufacturers.

Power Specifications of the FSP Hydro PTM+ PSU
(Rated @ Unknown °C)
AC INPUT 100 - 240 VAC, 50 - 60 Hz
RAIL +3.3V +5V +12V +5Vsb -12V
MAX OUTPUT 24A 24A 100A 3A 0,3A
120W 1200W 15W 3.6W

FSP does not officially disclose how efficient the Hydro PTM+ is at 1400 W, but says that the PSU remains silent even under maximum loads. This is an interesting claim, as users who regularly push 1000W+ tend to be compute, rendering, or cryptocurrency focused.

Being aimed at enthusiasts and gamers, the FSP HPT1200M is fully modular, has built-in RGB LEDs, and is compatible with the ASUS Aura Sync lighting controls. The power supply is outfitted with a 24-pin ATX power connector, two 4+4-pin EPS power plugs as well as eight 6+2-pin auxiliary PCIe connectors, a configuration that enables it to handle dual-socket motherboards with four ultra-high-end graphics cards. The last time we tested a dual processor system with four GPUs at AnandTech, a dual socket 1366 with four HD 7970s, it was drawing 1550W at the wall during cryptocurrency, for perspective.

The FSP Hydro PTM+ 1200 W PSU will be available shortly for $699 from retailers like Amazon and Newegg. The MSRP of the FSP HPT1200M is considerably higher than the price of other high-end 1200 W 80Plus Platinum PSUs (the EVGA SuperNOVA 1200 is available for roughly $350), which is logical considering the unique nature of a liquid-cooled PSU. The 'good' news is that the first 500 buyers of the FSP Hydro PTM+ 1200 W PSU will get a free AIO LCS from Bitspower that includes a pump, a radiator, and a 120-mm fan. In addition, FSP will bundle sleeved cables with the PSU. This offer is apparently worldwide.

FSP and Bitspower were not the first to develop a liquid-cooled PSU for enthusiast-class PCs. For example, Deepcool demonstrated such power supply several years ago, but it never entered mass production.

    I sort of get what they are doing here, but it really feels like a "water cool ALL THE THINGS" sort of moment.

    There's this car that runs on water man!!

  • meacupla - Wednesday, February 7, 2018 - link

    Well, it makes more sense than water cooling RAM
  • nismotigerwvu - Wednesday, February 7, 2018 - link

    Yeah, I mean if you tried hard enough you could argue that anything that needs active cooling could benefit from a water cooled system, but it would have to be a pretty beefy part to make it worthwhile. I guess a PSU with an output that could logically be expressed in kilowatts might count as beefy as well.

    80+ Platinum means the PSU is at least 89% efficient under full load - which is 1200W - so it generates roughly 120-130W of waste heat. That's more than most CPU and worth liquid cooling IMO

    Only an $_$-RGB-FOOL-FTW-^_^ and his overdrawn credit card will think this is a good idea...
  • nerd1 - Wednesday, February 7, 2018 - link

    "Normal" 1200W Platinum PSU already costs $300-400, and if you need such a PSU you will probably use $10,000 worth of parts too so extra $200 is almost nothing.

    I won't use such a experimental PSU for my $10,000 workstation though.

    I've sure it's perfectly safe, but there's something about combining "water cooling loop" and "1400W of mains electricity" in the same device that makes me a bit nervous!
  • Beaver M. - Thursday, February 8, 2018 - link

    That fear isnt unjustified.
    Look into forums and find the liquid cooling threads. They always have huge problems with leaks (cracks in components, leaking connections, etc), even frying hardware components often because of that.
    Its just not worth it.
    I wouldnt want water anywhere near my PSU.
    Even AIOs often get leaks when they get old or are of low quality.

    This would be one of those examples where a heat-pipe would have been better. The water part would have been outside the power envelope.
