As can be expected, this unit looks exactly like its big brother. The housing is identical.

Except for the load table stickers, of course.

Some power supplies offer two sets of mounting holes so that their units can be mounted any way you wish. This isn’t one of those units, not that it usually matters much on many of today’s cases. Most of mine offer dual sets of mounting holes, so having the extras on the power supply is not needed.

Ah, it’s time to fix up a load table. We have 2A less 5V capacity and 8.3A less 12V capacity than the 650W model… that’s all. Of course, EVGA still rates this as being able to do full power at fifty degrees. Gotta love that.

If you stand on your head, you’ll notice this load table is the same as the other one. Go on… stand on your heads. I can’t be the only one getting a headache right now.

It comes as no surprise to me that the modular connectors are also identical to big brother. The two units are simply too close in capacity to make any real changes here.

For the record, you’re dealing with Torx T-20 screws to mount the fan, and T-8 screws to get inside the unit on this model. Of course, you will have to kill the warranty to mess around with that stuff, and it’s never good to do such things if you’re not trained for that sort of thing.

I have to admit, I’m really digging the aesthetics of the top panel on these units lately. It’s not just a couple of boring stickers. Looks good to me.

Most of the cabling on this unit is identical to big brother. I know, I know, it’s quite a shock. Yes, there are capacitors in most of these cables, which makes modding a little more difficult.

Two PCI-e cables come with this unit. In a strange turn, one is a single 6+2 pin affair, while the other…

…is this here 6+2 pin and 6 pin cable. So, if you use both cables, you get three connectors. Odd.

The 650W model had two Molex chains with it. This one has only one chain. No complaints here… I don’t need many of them in a build these days unless I’m building a crypto miner.

This unit comes with as many SATA chains as the 650W model did. No complaints there… it’s a little overkill for a 550W model, but we’ll take the extra cable anyway.

And of course, the only Berg connector is on an adapter. The way I like them.

While the 650W model had a combo CPU cable with both an 8 pin and a 4+4 pin connector on the end, this one only has the one 4+4 pin connector. This is really all we needed for both models, I reckon.
