Corsair VENGEANCE 650M Power Supply

It’s been a little while since we looked at a Corsair unit, so let’s take a look at something new from them. What I have for you today is the brand new VENGEANCE 650W unit. This is a quad 12V model intended to compete in the European market, where they haven’t quite bought into the whole “single 12V is better” nonsense that still seems to be prevalent in this hemisphere. But is it any good as a power supply? There’s only one way to be sure, and that is to throw it at the load tester and see if it sticks.

The world can be a little odd when it comes to power supplies. Units that do well in one part of the planet often find themselves struggling in other parts. Corsair is no stranger to this effect. In Germany, where users haven’t quite ever bought into the whole “single 12V is better” myth, Corsair thought they would do well to bring in an affordable product with a proper multi-rail distribution of the 12 volt output and build quality to rival the likes of BeQuiet. The VENGEANCE line of units is the result of all this, and we’re going to check them out starting today.

I have two units from this new line here in the lab… today I’ll be looking at the larger of them, the 650W model. With such things as Japanese capacitors, a five-year warranty, and semi-modularity; this unit should put in a good showing for itself. It’s only certified 80 Plus Bronze, yes, but you have to remember… this is for the European market where they run 240V AC mains and power supplies are almost guaranteed to be higher efficiency than they are here. Efficiency in North America is less of a priority for this guy.

But wait… there actually is a full set of certifications now for 230V operation. Bronze over there means we need 81%-85%-81% at 20%-50%-100% loading. That being said, I will be testing at 115V so we’ll have to go by the North American numbers. If we hit Bronze here, it should be a shoo-in for Europe.

Like almost all units I test, there’s marketing on the box. Mostly stuff we already saw on the front of the box, but there is also some useful information like fan curves and a load table. Good to see it confirmed that I can load test at 120V – I don’t want to wake up Kong today.

Just in case you were confused about the main selling points of this unit, here they are again. I’ve said it before and I’ll say it again – multi-rail done correctly is a good thing, not a bad thing. I actually prefer it on big watt monster units, and so should you. Down here at 650 watts it’s not quite as important, but I’ve still seen reports of single 12V units this size burning peripheral cables due to faulty connectors. Multi-rail done right is able to cut down on those instances.

Even so, at 650W I tend not to care about whether a unit is or is not single 12V as long as the unit has proper protection.

Cables? This power supply has them. With connectors on the ends, too. I am rather pleased to see the Berg connector is off on its own adapter… there’s nothing worse than an obsolete connector able to be easily jacked in wrong being forced on a cable we might need to actually use, is there?

Quiet, efficient operation, huh? We’ll just have to see about that. The efficient part of it, anyway. I can’t evaluate acoustics because of the load tester fans. It’s like going to a Rolling Stones concert and trying to figure out how loud that guy singing off key in the front row is over the sound of Mick Jagger’s lips flapping together. It’s all but impossible, is what I’m saying.

Let’s open things up now and unpack.

I see no user manual of any kind in there. It’s all on the site, along with the official specs and such. That said, we do get a warranty guide, recycling guide, some modular cables, some zip ties, a European power cord, and some screws. Seems ok to me for a bargain unit.
