A Detailed Look
The Seasonic FOCUS PLUS Gold 650W power supply enclosure is painted matte black and measures 140mm (5.5”) deep. The back panel includes an AC receptacle, Hybrid Mode switch, and main power On-Off switch. The PSU includes Seasonic’s premium Hybrid Fan Control (S3FC) which allows semi fanless operation when engaged.
The high-quality Hong Hua fan (HA1225H12F-Z) is rated for 0.58A, 2200 rpm, 73.9 CFM, and 32.4 dBA at 12 VDC. The fan incorporates a Fluid Dynamic Bearing (FDB) for long life and quiet operation.
The front panel on the FOCUS PLUS 650W PSU incorporates eleven modular cable connectors nicely keyed and labelled to prevent inadvertently plugging a cable into the wrong connector.
The modular cables are a combination of sleeved and flat ribbon-style with flexible insulation for easy cable routing.
Under the Hood
Here are a few pictures showing the layout and components inside the FOCUS PLUS 650W Gold power supply. Seasonic has a brand new platform for the FOCUS PLUS (FX) series.
The PSU incorporates a full bridge LLC resonant design with DC-to-DC converters to generate the +3.3V and +5V outputs from the +12V supply. The layout of components is very clean and the soldering appears to be excellent as we would expect from Seasonic. All of the capacitors are high quality including the aluminum electrolytic solid polymer caps. For example, the primary bulk capacitor is made by Nippon Chemi-Con and is rated for 450uf, 400V and 105°C.
Good read – and good to see
Good read – and good to see Seasonic on top of their game yet. I’m due for a new build soon and this looks like a really good option.
My main gaming PC is running a 10 year old Seasonic M12 SS-600HM and it’s still going strong through a couple board/CPU upgrades and multiple graphics card upgrades.
It is good that PSU
It is good that PSU manufacturers understand that the 230 mm power supplies of half a decade ago are not really needed anymore. Sure, it may look cool to some because they believe bigger to be better, but a short power supply for anything under a kilowatt is just fine given proper design.
I just need a reason to
I just need a reason to change my 7 year old seasonic that is serving its 3rd build.. But am feeling guilty of replacing a perfectly good, reliable and working PSU that has no problems.. Damn you Seasonic.
Well done Seasonic-you set

This PSU seems to be of insane value as it is smaller, better AND cheaper then the Corsiar RM650x!
“our PSU was delivered
“our PSU was delivered straight from Newegg.com inventory.” On front page yet last page says “Our thanks to Seasonic for sending us the FOCUS PLUS 650W Gold PSU to review!” Guess they are getting the cherry picked samples.

It ordered by Seasonic from reseller’s stock… Good job Sherlock to find out nothing… 😉
650RM vs 650FX, 650RM “old
650RM vs 650FX, 650RM “old model” is better than the “new” 650FX
why?
the old had more available cables such as 4+4 attached for cpu power and an extra 1×8 12v for cpu as well, this way here you did not need buy a higher wattage PSU that you will not need for nothing.
some builds that you may have an extra powerful cpu you may not have need of an extra power gpu, but even than, 450w of power is quite a bit of juice for even a very high end core i7 overclocked as well as pretty much any modern AMD or Nvidia graphics card (single one at least) in an overclocked state, so 54a 12v is plenty really, this saves you from having to buy an adapter for the extra cpu power (which quite a few motherboards are now using)
Seasonic is top quality bar none, but, it seems they took a hit on functionality “upgrading” from the semi-modular 650RM to the full modular 650FX, not quite as much in the 3v or 5v rails as well as a few cable change but also costing on average a little bit more $.
glad I bought the 650RM….as well, the cables that are not modular 99% of the time you will be using them anyways ^.^
Hello, do you have maybe
Hello, do you have maybe cab;e pinout for focus plus series?
Hey guys should i put into PSU another 8pin cable for my new 3080 OR it will be enough if I stick with one that’s is connected to my 1060 (it has another 8pin plug)
Technically just one cable is enough to support both 8-pin connectors, but I like to use two separate cables when possible. The 3080 is capable of pulling quite a bit over 320 W in instantaneous bursts.
Thanks fo the reply 🙂 i will pług second cable for platform stability 🙂
And one more quick question in second PC i will probably install 3070 (unit with same seasonic psu) in that rig one cable should be totally ok
