And now we see the unit itself, done up in black and a sort of brownish-gold.

I find the aesthetics of the unit pleasing enough but have seen units I’ve liked the looks of a bit better.

Ah, good – we get a big clackety-clack power switch. While these aren’t always necessary, as was the case with the Corsair AX1500i, they do give off an impression of reliability.

Here’s a side panel of the unit. I like the little “SS” pattern stamped into those lines near the top.

This is the modular cable end of the unit. As is the case with most recent high-end Seasonic’s, there’s a fan control switch here too. The unit actually came with a big blue sticker over this area explaining how to use that switch, but we’ve all seen that before so I opted to just get rid of it before shooting this shot.

On this side of the unit, we find our load table. Let me just make up one of my own, here.

Looks like the specifications of this unit are exactly the same as the older version of the X-1250. Good, this means I can load test this one the same way.

You know, maybe I’m just having an off day, but I don’t really care for the looks of this fan grille. I think it’s mostly the color. It certainly has nothing to do with functionality… this should easily get the job of cooling the unit done.

This shot here would be my way of showing you all the modular cables that come with this unit. And there are a ton of them.

Here are the two CPU cables. One’s a modular 4+4 pin affair, the other is a straight 8 pin EPS12V.

Only the main ATX cable is a traditional sleeved cable. All others are ribbon cabling, nice and flexible. No complaints from me on that… the ATX cable doesn’t work so well as ribbon style.

Finally, some of the peripheral cables, along with the 3.5″ adapter. I’ll be honest… I am thinking seriously of scoring against any 3.5″ connector I see at the end of any modular or hardwired cable. Nobody uses those connectors anymore, because nobody needs them anymore. Soon, the only way you might see me do a 10 in functionality scoring is if any included 3.5″ connectors are off on their own adapter, like this. I’m sick of seeing them. They need to crawl off into a dark corner and fade from existence if you ask me.

I have no major issues with any cable lengths on this unit. I could see some people running into trouble with super big cases and getting the peripheral cables to reach to the top while using all four SATA connectors, but since 5.25″ drives of any type are no longer must-have devices anymore I’m not going to score against that.
