FSP Hydro PTM PRO 1350W Power Supply, 80 Plus Platinum, ATX 3.1 & PCIe 5.1 (12V-2X6) X2, Full Modular (HPT2-1350M, GEN5)

It works fine in my system, however, there are two things that I don't like about it. The 12VHPWR voltage sags under load with my RTX 4090 and I see it dip to 11.9v while gaming something my evga supernova g2 1300w never did. I have a sensor panel right in front of me all the time with system voltages on display so I can see it. The +12v line also dips the same way. I never see the 3.3 and 5v lines sag.The only sleeved cable is the 12v-2x6, all others are bare which I really don't care for. At this price point all cables should be sleeved.Would I buy it again? Probably not and would seek a Corsair atx 3.1 unit first.

The media could not be loaded. The FSP Hydro PTM PRO 1350W is a beefy power supply with plenty of power for nearly any enthusiast PC build out there, including those with the latest Nvidia 4090 or AMD 7900 XTX cards. For the former, the PSU is ATX 3.0 compliant which means it comes with the two 12+4 12VHPWR cables without having to use an adapter, and for the latter there’s three 6+2 cables supporting up to four GPU connectors.The packaging includes pretty much every cable in addition to the ones above that might be needed for your build, including the venerable Molex HDD connectors. Also in the package are a C19 to NEMA 5-15P power cable, total of 5 cable ties, screws, flashy side stickers for those into that sort of thing, and a jumper connector to turn on the PSU without a motherboard if you need to debug or test it.Installation in my case was a bit tricky, as there was very little room to spare. I made it work, but I’d suggest checking your own case compatibility - this is a 160mm PSU. Furthermore, it uses the higher amperage C19 connector which means that making it work in cases that use a front to back passthrough power connector will be complicated without an additional adapter, as those passthrough connectors (C13) will not be compatible. C19 adapters and cables are available, but are not as common and can be a bit pricey, so keep that in mind. This is not a detraction against this PSU by any means, as at its maximum possible wattage the C19 connector is required due to higher amperage that C13 cannot handle.Flat cables were much easier to work with and organize compared to typical bundled up cables, especially in my smaller case.Another rather interesting feature of this PSU, as part of the “Hydro” branding is the usage of conformal coating on the circuit board which helps with preventing issues in high humidity environments. So if you are located in a humid climate, this may help with long term reliability.Warranty is excellent at 10 years.Efficiency is very high due to it being rated at Titanium. I would have expected to see this PSU being listed on the Cybernetics site as other FSP units are, but it just might be too new to be there. 12V rail is a whopping 112.5A maximum, so this definitely is putting out power where needed.I did run into some issues. The first one is with the eco switch. The eco switch is the small switch on the back of the PSU. With it on, the fan won’t turn on until a certain amount of load on the PSU, so that it stays effectively passive during typical desktop use. However, once I start gaming and putting some load on the PSU, the fan will eventually turn on as expected, but at a fairly high RPM and quite noticeable and sudden noise level.Secondly, with the eco switch off (fan always turned on), the PSU makes these random quite audible crackling noises (recording attached). By toggling the eco switch on and off, it seems that these noises are coming from the PSU fan itself and are more prevalent and noticeable at certain speeds. It’s almost like it’s catching on something inside randomly. I’m unsure if this is a flaw of my unit specifically or a more prevalent problem.Value: The PSU is priced reasonably given its features, but there is competition at the same or higher wattage, power, and efficiency. FSP may need to look at what’s currently out there and see what can be done to improve the value proposition a bit, especially if the issues noted above are more prevalent.

It is a very good PSU for the price. The power output is very solid (platinum grade). It is very quite during close to max uses. The cable management is very simple & easy to control thanks to the pins that are provided for in the package. Solid 5 stars.
