Seasonic comes to us today bearing a new revision of the value-oriented 80 Plus Gold G-550. Shall we have a look and see if anything has changed for this platform? I’m curious. Let’s give it a whirl.

No, you’re not seeing things. A little over a year ago, I did indeed review the Seasonic G Series 550 watt unit. Why am I looking at it again today? Well, to put it simply, Seasonic has come up with a new “F3” revision of this unit and they’ve asked us to put it through its paces. So, that’s what I’ll be doing today.

This is a more bargain oriented unit from them with 80 Plus Gold efficiency, so it’ll be interesting to see just how much this unit differs from the older model.

It’s a cold, rainy Chicago night. I’m walkin’ home from dis bar when dis dame comes up to me and asks for a light. “Detective Wolf, I need your help,” she says like I got time for dis in da middle o’ da night. I pull out a cigarette and says to her, “Ya got a light fa me instead, toots?” Then I remember I don’t smoke so I t’rew it in her face. She slaps me, turns, and walks off into da night. Some guy starts playin’ a saxophone in da background. I button up my trenchcoat a little more against da rain, watchin’ da broad as she gets ta da end of da street. I raise my hands to my mouth and yell, “Daaaaaaaa Bearsssss!”

What? Oh, right, I’m supposed to be reviewing this power supply, not writing some kind of weird 40s detective novel. I’ve converted the above shot to black and white to make the letting more readable… it’s all done in this eye gougingly irritating shade of gold, which is damn hard to photograph. The marketing found on here is pretty much the same as the older version of this unit, so I’ll just move to the next shot.

Judging from this side of the box, the unit inside it has the exact same specifications as the earlier revision did. That should make it easier to compare them, no?

Da girl turns at my bad George Wendt impersonation. “You better leave me alone or I’ll call the fuzz,” she yells. Da guy wit da sax stops for a second ta blow out his spit valve. Turns out he was followin’ me, ’cause he did it down da back a’ my neck. After I punch him, I tell her ta go ahead and then offer ta show her the old Polish sausage. She runs back over ta me, slaps me again, den runs back down da street and doesn’t stop. I reach inta my coat and pull out my bag o’ sausages from Swerski’s Meats. Pulling one out, I chew on it thoughtfully as I watch da broad go. She coulda had one wit me. Da guy wit da sax starts playing again. I punch him again.

Sorry, guys. I guess I’d better stop with the black and white shots now. Let’s get this box opened up.

Allegedly, there is indeed a power supply in there. Let’s find out.

Ah, yes. A power supply, a bag of modular cables, a bag of goodies, a manual, and a warranty info sheet.

Here’s the manual. Better than nothing, but pretty much useless from a specifications point of view. That’ll have some impact on my scoring later.

The warranty on this unit is five years. Not too bad, for a more affordable option like this one.
