techpowerup FSP Hydro PTM Pro 1200 W Review - A Silent Power Factory

FSP introduced a new high-end PSU a while ago, the Hydro PTM Pro with 1200 W maximum power output. There are two more members of the family with capacities of 1000 W and 850 W. According to FSP, this PSU uses a conformal coating that protects its internals from dust, stains, and humidity. All of these PSUs are also fully modular, and the side stickers are easily swapped out for others included in the bundle.

 

The semi-passive fan operation can be deactivated with a switch at the face of the PSU. FSP dubbed it the "Eco" switch since power consumption is lower with the fan deactivated. The truth of the matter is that the the overall efficiency gain is only noticeable at very low loads. The fan-stop feature can also decrease the lifespan of FDB fans as the friction in such fans is higher during start-up because the lubricant hasn't yet been pumped up the spiral groove and onto the whole bearing surface, which doesn't apply to double ball bearing fans. A PWM fan-control circuit would have been better as it makes for very low speeds which have the fan operate throughout at very low noise output.

 

A major upgrade with the Hydro PTM Pro 1200 W is its compliance with the IEC 62368 electrical safety standard.

Seems to be a middle of the pack high wattage unit, not to say its bad, but some notable issues TechPower-up had with the unit during their testing:

• Two EPS connectors on the same cable
  • axipher: there are two cables, one with a single 4/4, the other with an 8 + a 4/4.  So to a new user with a motherboard that has two 8-pins, or 8+4, they could end up using the single cable with dual connectors.  This *could* cause issues if they do some big overclocks are are running HEDT off of it so I can understand putting this as a downside to this PSU
• Low efficiency with 2% load
  • axipher: my quick look through shows this as the only test where they ran at 115 V, all the rest was at 230 V
• Large dimensions (190 mm deep)
  • axipher: Wouldn't really call this a con on its own since most high-power systems are going to be in larger cases anyway, but there are other options taht are shorter, I wouldn't have deducted points for this, just noted it.
• Not fully compatible with the newest ATX specification (v2.52)
  • axipher: LTT has a nice break-down for those interested
