Corsair AX1200 1200W Power Supply Review

Cabling Arrangement




Whew, that's quite the list of cables and connectors. As always, there is the 20+4 pin main connector. There are also two ATX 4+4/EPS12V cables for motherboards that require it. To power a trio of high end GPU's, there are six PCI-E cables of the 6+2 variety so that they can be used in whatever manner you want. For those that still need 4-pin Molex connectors, there are three cables each with four connectors on it to give you a total of 12 Molex connections. SATA cables come in two different lengths. There are two shorter SATA cables with two connections each. For the longer SATA cables, there are three cables each with four connectors. This gives you a total 16 SATA connections.


One thing that we are very happy to see is that Corsair has not included FDD connectors as part of the modular cables. In the rare event that you should need them, Corsair includes two 4-pin Molex to FDD connectors. It would be nice if we would see more power supplies come to the market like this.




The Corsair AX1200 has simple rail distribution with everything on a single 12V rail. Normally this is about all we have to say on single rail power supplies, but the AX1200 does bring up a concern for some. Since all the power is coming from the 12V rail, there is 100.4A of power here. That's a lot of juice and it can melt the cable sheathing on even some very thick wires. This isn't necessarily an issue, just something that some people will have issue with. We aren't worried about it here, though.



A Look Inside




Since everyone wants to see just how this bad boy is laid out on the inside, here is a look with the bottom taken off of the power supply. Everything is very neat and tidy, partially due to the 100% modular design and the lack of a large clump of cables terminating inside the power supply. Five different heatsinks adorn the back half of the power supply to help cool things down.




On the primary side of the power supply, we see that Corsair has chosen a pair of Nichicon capacitors. For those that don't know, Nichicon Corporation is a very large Japanese company known primarily for their high quality capacitors and was established in 1950.




Corsair chose to utilize Nippon Chemi-con caps where needed on the secondary side of the power supply, giving the AX1200 100% Japanese capacitor construction.




Rounding up our shots of the inside of the AX1200 is a shot of the exhaust fan. It is a 140mm Yate Loon fan, model D14BH-12.
