Corsair HX1200 PSU Review

Final Analysis

The HX1200 is another high-performance PSU from Corsair based on a CWT platform. You get the top-end semi-digital platform, remove the digital interface but keep the fan's micro-controller, drop the price a little, and change the model number.

Due the recent mining craziness, don't expect to find high-capacity HX PSUs readily available, especially at the official price tag of $230. That MSRP is quite good, considering Corsair's build quality, super-long warranty, and excellent performance. Given reasonable value, we expect the whole HX line-up to be successful for Corsair, similar to its RMx family. You see, not all enthusiasts are control freaks. Many don't mind if they can't monitor the status of their power supply or manipulate its operation.

On the other hand, we'd still spend a little more money on the HX1200i, even though it uses the older Type 3 cables without extra filtering caps. We actually think the HX1200i's ribbon-style cables are easier to work with. The main ATX, EPS, and PCIe cables of the HX1200 won't be so easy to route inside your case because they are bulky. That's the price to pay for in-cable filtering caps.

The HX1200 is fully modular, it offers high performance, and is incredibly quiet, putting to shame lower-capacity units in our noise output measurements. Even if Corsair's HX1200i is even quieter, we cannot ding the HX1200 for results under 25 dB(A). With the extra-long warranty that Corsair provides with its high-end PSUs, you won't have to worry about longevity, that's for sure.

Then again, if your plan is to drop this PSU into a mining rig and operate it under harsh conditions 24/7, we're thinking the 10-year coverage will eventually become a problem for Corsair. Several brands are already thinking about how to deal with mining, since when they decided to offer such long warranty periods, they didn't consider that there would be cases where the PSUs would be subjected to taxing loads around the clock, negatively affecting long-term reliability. Moreover, there is no way determine whether a PSU was used normally or for mining. To be frank, it'd look odd if a brand offered 10 years of coverage for light use and only one for mining. In our opinion, the PSU brands are engaging in an unrealistic warranty race. The health of a power supply depends on many external factors, and the guarantee behind it should be sustainable to protect the manufacturer from unexpected losses in the long run. If it gets bad enough, those can cause price increases, layoffs, or even bankruptcy. Marketing sometimes isn't the best consultant, and the main reason we have 10- and 12-year warranties is marketing.

    Not another plug/connector change!. I, like many people on this site, build custom PC's, part of which includes sleeved cables. One bug bear is 2 wires into 1, which is a in in the arse. I personally like the HXi series of Corsair PSU's which only have one such connection. I also think the 24 pin ATX supply is outdated and needs revision. I can't see the point of supplying motherboards with 3.3 and 5v rails. If only 12v was supplied with any or all voltage reduction made on board life would be so much simpler and neater. By providing more noise reduction at source (the PSU) gives Motherboard manufacturers an open cart to reduce the quality of voltage regulation i.e capacitor quality, on the motherboard. Is there really a need for another PSU on the market?

    On the specifications table it says: "Efficiency: 80 PLUS Gold, ETA-B", which is wrong since this is a Platinum PSU.

    yes we didn't pay much attention to the 80 PLUS efficiency certification :)

    ^^What are you talking about? Register and get on Corsair's support forums:

    https://sso.corsair.com/idp/AuthnEngine#/authn

    Of course they have a customer support phone number: 888-222-4346 (North America customers).

    Anyway, back on topic, first the $#@! miners have negatively impacted our GPU market, and now they may negatively impact our PSU market. :fou: What makes this really aggravating is that the PSU makers really can't prove a PSU was used 7x24 for heavy mining operation.

    Worse, even if PSU vendors like Corsair offer a mining-specific PSU for less money with just say a 2-3 year warranty, nothing would stop the miners from buying the full 10-year variant. This mining craze is becoming a real pain to we PC enthusiasts.

    You are making everyone's head hurt. If you want to complain about Corsair, then do so on Corsair's customer support forums and social media. Also, just FYI, Tom's only reviews what is sent to them. They do not go "cherry pick" buy products and review them. For someone who is an alleged "original reader" of Tom's I'd have expected you to understand that.

    Bro.. You're all over the place. :D

    So only the 24-pin is pin incompatible with the Type 3 cables. And yes... it's because of the extra sense wires. If you're really going to get all wound up about having to do 2-to-1 wires when doing custom cables, you know what you should do? Don't do 2-to-1 wires. They're only sense wires. The lack of them doesn't prevent the PSU from working. It'll just make your voltage regulation "as bad" as any other PSU that doesn't have the sense wires.

    Yes. The ATX spec is out of date. But Intel wrote it and nobody is going ot implement a new standard without Intel's blessing. They even released a whole new ATX design guide last month that changes almost everything (T1 timing, T3 timing, standby efficiency..) but DID NOT TOUCH the pinout (they made -12V "optional", but that's hardly much of a change).
