Seasonic PRIME Ultra 650 Titanium Power Supply

Seasonic has been on a real winning streak for a few years now. It seems like each time we see them, they bring a little better performance each time. Now, they’re freshening up the successful Prime line of units and calling them Prime Ultra. I have the 650W Titanium variant in front of me. Let’s see what improved this time.

PRIME Ultra 650 Titanium

Seasonic’s at it again, apparently. Not content with the original Prime Titanium units simply being awesome, they’re trying to one up themselves barely a year later with the new Prime Ultra Titanium units. Today, I’ll check out the 650W model in the line.

I have to confess that I don’t see a point to this, really. The originals were plenty good enough to hold the competitions’ feet to the fire for years. But I won’t complain either, if improvements show up in the performance later. That said, Seasonic’s press release about these units doesn’t give me too much optimism for that. The differences between the new and old lines looks to me minimal… just a few little changes here and there. Like a SATA 3.3 adapter being included, different SATA connectors, and the addition of a PSU tester like the one EVGA throws into their high end PSU retail boxes. There’s really not much mention of any performance improvements. As if the original wasn’t good enough.

Like all power supply boxes, this one has many sides. And they are all annoyingly shiny enough to make shooting them hard. Here’s some essential data on the unit contained inside.

The box also has printed on it a diagram of the cables and connectors. This diagram is wrong. One cable that should be here is not, one cable that is promised isn’t here. More on that later, but… you’re probably not going to care either way.

And here’s the back of the box, promising the usual promises. 0.5% regulation, low ripple and noise, premium parts, FDB fan, fully modular… all the stuff we expect from a flagship Seasonic unit these days.

Let’s unpack this unit now.

Seasonic looks to have gone a bit overboard with the goodies on this one, no? We have a bag of power supply, a bag of cables, a power cord, a quick start guide, two user guides, some kind of a contest voucher, and a fancy bag of accessories.

Now, looking at all that documentation you’d think that Seasonic was going after Silverstone for documentation overkill. That is not the case. In fact, the two manuals combined actually have less information present than past Seasonic units. One is almost completely dedicated to marketing this unit with a few cable specs thrown in (that happen to be as accurate as the diagram on the box). The other is mostly about installation, troubleshooting, and warranty.

Neither manual has a single actual specification beyond the cables and connectors for the unit at hand printed in it anywhere. This stands in stark contrast with Silverstone, where you also get two manuals, but one manual is dedicated to specifications alone. This’ll provoke a scoring deduction later.

The contents of the accessories bag. Two stickers, a buttload of zip ties, the power supply tester, some screws, and some branded cable ties.

The tester works the same way it does for EVGA models. Plug it into the motherboard end of the ATX cable, and it brings the PSU out of standby so you can check it out. Never do this with hardware plugged into the unit if you suspect a problem with the unit. That’s a good way to bork your hardware.
