SeaSonic Electronics SSR-1200PD overview

  • 1Description

The Prime 1200W 80 Plus Platinum Modular ATX Power Supply from SeaSonic Electronics sports a single rail that delivers up to 1200W of power for all the internal components inside a desktop system. The power supply comes with modular cables that connect to eight PCIe cards, twelve SATA drives, five molex-compatible devices, and other essential equipment. Aside from delivering power, the modular cables help maximize the internal space in a compact chassis by letting you remove unused cables. With an 80-PLUS Platinum rating, the PSU efficiently converts power coming from the source to offer you lower operating costs. There's also an onboard variable speed 135mm fan for quietly cooling the PSU.

80 PLUS Platinum
The high-efficient 80 PLUS Platinum certification offers greater than 90 %, 92 %, and 89 % efficiency at 20 %, 50 %, and 100 % operating loads, respectively. With an 80 PLUS Platinum rating, this power supply will waste less energy during power conversion, lowering operating costs for the user.
Fluid Dynamic Fan Bearing
The Fluid Dynamic Bearing (FDB) fan is designed to take advantage of the impact absorbance effects of oil. It is reliable and generates less operating noise and heat than ball bearing fans. The lubrication of the bearing surface reduces friction and vibration and therefore lowers overall power consumption. This type of fan technology also increases the lifespan of the fan.
Power Supply Sound
With Seasonic's Hybrid mode, the onboard fan can operate at various spin speeds to help eliminate noise.
Micro Tolerance Load Regulation
Seasonic's design keeps the output voltage within a very tight range, achieving under 1 % load regulation.
Cable-Free Connection Design
With a special design feature, the back panel and PCB (Printed Circuit Board) are connected by a copper plate. This solution lowers the chance of production errors during manual insertion and improves output power quality.
Multi-GPU Setup
8 PCIe (6+2-pin) connections are available to support multi-GPU setups.
Gold-Plated Connectors
Gold plating critical connector pins (motherboard, CPU and PCIe cables) extends the lifetime of the connectors and increases the efficiency of current transmission.

    PRIME 1200W 80 Plus Platinum Modular ATX Power Supply is rated 3.7 out of 5 by 6.
    Rated 1 out of 5 by from Just Bad This PSU worked only about one week then it died. I tried unplug all the cables then plug them in again one by one and then I tried turn on the PSU each time I plug in a cable. Still, it won't turn on. I even plugged in only motherboard cable 24 pin connector from PSU to the motherboard, the motherboard's LED light turned on ,but not the power supply. I also heard coil noises from the power supply after I pressed the case power button. Really disappointed.

    Rated 5 out of 5 by from Solid Fully loaded PSU I was looking for a high wattage PSU for running multiple graphics cards. SeaSonic PRIME 1200W 80 Plus Platinum was the best Platinum rated value for money PSU that I shortlisted after an extensive online search. After using for about a week, I must say that I am extremely satisfied, at the moment I am only drawing about 50% of the rated power, but it has been running very stable and silent. Also it is running quite cool and not hot at all. The box had all the power cable connectors you would ever need. The cables themselves are well built and sturdy. Only thing that someone can complain about slightly is that the cables are a little heavier and thicker and although they are flexible, not very easy to arrange them properly in a cramped Case, Somebody on a smaller Case wouldnt require a 1200W PSU though :) Overall extremely satisfied and would get one for my next rig as well.

    Rated 5 out of 5 by from Great PSU for gaming I bought this so I could start gaming and work on my VR startup. I needed enough power to supply more then 2 video cards and this fits the bill! Comes with plenty of molex and SATA connectors. Also included a nifty baggie and some cable sorting Velcro as well as zip ties!

    Rated 5 out of 5 by from solid and reliable PSU A feeling when I opened it that this is very reliable heavy duty PSU is strong. I believe it is one of the most cost-efficient PSU you can buy from the market.
