It’s time for some action, Jackson. It’s time for some science stuff, McGruff. It’s time for some load testing… er, Pesting. One SM-268 will be all I need to load this little guy today, and the rest of the test bench will be in play as always.
|SS-350TGM TFX – STANDBY Load Tests|
|Test #||+5VSB||DC Watts/
As always, we start with the standby load tests. Because this is a little guy with less capacity here than the ATX units I test, maintaining above average efficiency results and fantastic voltage readings is a bit easier.
On this one, I get an above excellent result of 0.8% when it comes to standby voltage regulation. Not too shabby, Shabba.
|SS-350TGM TFX – Low Load Tests|
Though this is an 80 Plus Gold certified unit, I was ready for an efficiency result like this one. All this pushing for higher efficiency between 20-100% loading means that the efficiency drop off common to all SMPS designs has to go somewhere, and it’s always going to go to the lower power levels like this. We have mediocre efficiency here, yes, but this doesn’t mean we’re always going to get results like this.
Let’s run the main tests and find out for sure, though.

|Progressive Load Tests|
* Fanless operation.
** Intermittent fan operation.
Ah, yes… there’s your Gold efficiency right there. An easy pass on tests one, three, and five; just as I was hoping for. Very nice.
Let’s have a look at the voltage regulation now. Moving from left to right in the above table, I get 1.2%, 0.8%, 0.7%, and 0.7%. That gives us a most excellent average result of 0.85%, so it seems that Seasonic has brought their reputation for amazing voltage stability to this little guy. Awesome!
There’s really not too much else to say at this point in time. The fan stayed off until test three, and never got loud, but this unit is also running out in the open. It may become a different story in the hot box. Let’s go to the next page now.
