EVGA 650GM 650W SFX

We will now explore the unit itself. It’s a tiny little thing, small enough to palm, right on target with SFX dimensions. There’s no “L” at the end to denote a lengthened housing, just 650 watts in a box the size of my DSLR.

And yet, as the box promised, it is indeed fully modular. I still find it very impressive that we can get 650 watts at forty degrees out of something like this.

The exhaust grille shows us a lot of nothing. All visible components are wrapped in black, so I have nothing to go on for determining the OEM. We’ll try to solve that riddle later.

Meanwhile, here’s the load table. As mentioned, the max temp rating is forty degrees.

Now, a peek at the modular connectors. Nothing plugs in where we don’t want it. I have a suspicion based on these connectors who the OEM might be, but again that will wait for later.

Once again, EVGA has labeled SATA and Peripheral cables separately, but rest assured these cables are electrically compatible with one another and can be freely interchanged.

The fan shot from this side gives us not much new information, except that the grille is a simple stamped steel affair. This unit does have a semi-fanless mode to aid in silence, but really… 650 watt units this size aren’t going to be all that silent anyway once you start loading them down.

This view right here makes me wonder if perhaps I have been too hard on units with ribbon cables on the ATX. On this unit, the way the sleeving is done makes it just a bit hard to manage. I won’t score against it here, but may stop scoring against ribbons on cables this short for future SFX units like this.

Of course, I had to give some photo time to the Molex to Berg adapter as well, even though I can’t think of one dadgum use for it here in 2018.

Two PCI-e cables come with this unit, which is probably going to end up being overkill for most people. But it is appreciated nonetheless. A unit this size can handle two of my former 280X mining cards without running out of juice, so this is appreciated.

The CPU and Molex cable share this shot. I find it curious the Molex cable has so many connectors on it given the size of this unit, but if you’re like me that cable may not even get used.

Finally, we have two SATA cables with only two more connectors between them than the Molex cable has. Odd, but not to the point I need to score on it.

I will say, though, that Silverstone might be doing these cables a wee bit better when it comes to wire length between connectors… some of these SFX cases can put components far enough apart that you need such cables.
