Seasonic G Series 650W Power Supply

In today’s review, I’m looking at one of the higher-powered units in Seasonic’s G Series, a line of units intended to bring Seasonic’s awesome engineering talents to the budget-minded. This time, it’s the 650 watt model I have under the microscope. Let’s see how it does compare to the 550 watt model I looked at not too long ago.

Hellos, peoples, and Howard Hughes today? Sorry… I’ve been into the caffeine big time this morning, and my brain’s a bit loopier than usual.

Today we’re going to look at another unit from Seasonic. This time, it’s the G Series 650W model, big brother to the 360W and 550W units I looked at not long ago. You’ll recall that this is Seasonic’s more value-oriented performance line offering things like 80 Plus Gold efficiency and even semi-modularity on the higher powered models.

As is the usual case, we have some marketing to look at. But it’s all marketing we’ve seen before, so I’ll refrain from commenting on it this time. It should be noted, however, that I am still not seeing a maximum operating temperature spec on this unit. This was the case with the smaller models as well.

Since we do not have this data, I’ll go ahead and shoot for fifty degrees in the hot box, assuming I can get it that hot.

Specifications here, on this side of the box.

Contents here, on this side of the box. Y’all think I should unpack this now?

I knew you were going to say that, but I’m out of chocolate Twizzlers, sorry. You’ll have to go to the store. Meantime, I’ll just unpack the box.

A power supply, a power cord, a user guide, a bag of accessories, and a bag of cables. That’s what was in there, along with a hefty helping of air and foam.

Seasonic’s familiar blue and white warranty sheet was found lurking within the pages of the user guide.

And what does the user guide look like? Here you go. The fact that they included one is nice, but in terms of useful data it is severely lacking. There are no specs on the unit at all, which will cost Seasonic something in the score on the last page.

The contents of the accessories bag: some zip ties, some velcro ties, a case sticker, and some screws.
