Mistel Vision MX650 Fanless 650W

For now, we’ll have our first look at the unit itself, which appears to be using a design intended for a fan, just beefed up enough to allow fanless operation. Most fanless units are like that, which is why you need to make sure you put some airflow through them or run them heatsinks up so they can stay cool. Overtemp protection is included, according to the box, so the unit should shut down if it gets uncomfortable.

That said, my hot box is set up to be positively pressurized by the duct fans bringing the heat in from the load tester, so this unit will actually be getting some degree of cooling during testing.

I’m really liking the outward appearance of this thing already. There’s a ton of open grille area, yet the unit still looks fantastic.

On this side of things, we find what is normally the exhaust grille. I can’t tell the OEM yet from here, but I have to say it does look familiar. We’ll investigate more on page five.

For now, we need to look at the modular connectors. We’ve got the Aura Sync connector over on the left, and the usual connectors hogging most of the space as usual. Thankfully, Mistel avoided a common pitfall for these new companies by making sure that no cables can be plugged into the wrong connectors.

A top down shot shows us no fan, but instead gives us another look at the insides. Which look even more familiar to me now than they did a moment ago.

The load table makes an appearance here. Man… even some of the output specs look familiar to me, particularly on the minor rails.

Moving to the modular cables, we find a long ATX cable lacking the irritating capacitors we sometimes see in high end units. Wait… connectors, wire gauge… is this unit built by Seasonic? It kind of seems that way, yet I’m not so sure.

Like I said, we’ll solve that mystery on page five. I love the length of this cable… I reckon this unit would have no trouble getting to the top of my Corsair 900D, which recently told me the hard way even the ATX cable on my AX1600i was too short to reach the connector on the very top of my Asrock EP2C602. I basically had to abandon all attempts at cable management and run everything in front of the board rather than behind the tray before it would work.

Only the ATX cable is sleeved… the rest are ribbons. With no capacitors, and lots of length.

One CPU cable comes with this unit, and that will do the job at this power level.

No. This can’t be out of the Seasonic factory. They would never irritate me with that hardwired Berg connector at the end of this Molex cable like that. The mystery goes on.

Finally, here are the two SATA chains for this unit. I like that they are terminated in straight line connectors… sometimes those right angle jobs in the middle of these cables can be a nuisance. Other times, they can be a godsend.
