Corsair’s HX and TX-M series of PSUs go after the high end

Corsair is showing off two new series of ATX PC power supplies at the Consumer Electronics Show this year. The TX-M series has a semi-modular cable design and 80 Plus Gold certification, and capacities from 550 to 850W. The HX series (arguably a blast from the past) is for PC builders going all-out, with fully modular cables, 80 Plus Platinum efficiency, and power output up to 1200W.

Corsair offers TX-M power supplies in 550W, 650W, 750W, and 850W capacities. The largest unit measures 6.3" x 3.4" x 5.9" (16 cm x 8.6 cm x 15 cm), but all other models measure a slightly more compact 5.9" x 3.4" x 5.5" (15 cm x 8.6 cm x 14 cm). Corsair backs all TX-M PSUs with a seven-year warranty. The semi-modular cabling means there's a permanently-attached 24-pin ATX power connector, while CPU +12V power, SATA, PCIe, and Molex power connectors come on detachable cables.

The higher-end HX-series power supplies offer power efficiency as high as 94%. All the cabling is fully modular, too. Buyers can choose from 750W, 850W, 1000W, and 1200W models to suit their needs and wants. The mack-daddy HX 1200 measures 5.9" x 3.4" x 7.9" (15 cm x 8.6 cm x 20 cm), while the remaining units measure 5.9" x 3.4" x 7.1" (15 cm x 8.6 cm x 18 cm). The 1200W unit weighs over five pounds (2.3 kg), so buyers will need large cases made of sturdy materials to house and support that beast.

Corsair says both series are stuffed full of 105° C-rated capacitors from Japan. All HX models and all TX-M models except the TX550M have Corsair's Hybrid Silent Fan Control feature that turns off the spinner when the power supply is under a light load.

The TX-M and HX models are available now in Corsair's online store. The 80 Plus Gold-rated TX-Ms cost $80 to $130 and the 80 Plus Platinum HX series units cost $130 to $230 depending on capacity.

    I always forget so I always ask and someone always has a reasonable answer, but why on earth do we need 1200W, again?

    Overclocked 2011-3 150W processor let’s call it 300W with an overvolt to the moon and hypothetical 520mm radiator cooling it all, accompanied by a [i<]pair[/i<] of overclocked TitanX(P) graphics cards in SLI, 600W, and that's 1% of the top 1% of hardcore enthusiasts only. If you move to dual-socket boards and >2 GPUs for crazy mad compute you really shouldn't be looking at ATX at all. If you're a gamer with unlimited budget you're probably going to find the best overall gaming rig is something like an overclocked Broadwell-E i7-6850X which will probably hit 250W at peak load with a couple of watercooled GTX1080's. That rig might suck down 800-900W [i<]at the wall socket[/i<] if you're pushing it and the overclocks hard but more realistically it's going to be using ~600W if you don't want to be using ear defenders.

      Phase change maybe?

      Almost nobody does…but bigger numbers sell well. I try to get people to buy quality 450-500 watt supplies but I inevitably hear a complaint that it’s “not enough power” and that “this (crappy) 800 watt supply is only $10 more!”.

      I’m not going to comment on 1200W, but I recently overbought a PSU. I got an RMi 750W instead of a 550W unit that would have more than sufficed. Why? Because since it has a semi-passive fan, it spends almost the entirety of its life off 🙂

      Uhhhh… 10k RPM drives in some serious RAID config with multiple top tier GPUs doing some specialized form of GPUGPU computing?

      Really though, I’m sure there is SOMEONE who needs a 1200 GPU, but its like those guys who need a $1000+ CPU who aren’t doing actual work. Bigga numberz are teh better!

      Most people don’t need this but better believe some people have systems powerful enough to need this. Mostly on account of using lots of GPUs but the incidentals like water pumps and boatloads of fans and hard drives can be more than insignificant.

      Also, pretty much all high end PSU’s have a silent mode where the fan does not spin below some percentage of max load, so on a 1200w power supply the fan never spins if used with most systems

      Some people buy them because around 50% capacity is where they reach their peak stated efficiency of 94% and they plan to have a relatively normal system that uses around 600W at the most.

      Other than that though its for people who want to run 4x 1080’s overclocked with a overclocked CPU and 12 SSD’s with hardware RAID cards which is a very tiny few.

        SSDs and RAID cards add up to less than a few HDDs. My RAID card and 8 attached SSDs (plus another 2 on the Mobo) use less than 30 watts full load. 🙂

      1 sas card and many hdd
      2 for long term usage the older the psu it losing its spec
      3 3/4 way sli for old gpu 3/4 way crossfire and 1200 is too weak for example titan x pascal 250w then vega should be 300 without oc 4x gpu 2 cpu and you need 1500-1600w psu

      Biggest market for these are the folks that run Distributed Computing projects and have systems with 4 GPU’s running full tilt 24/7. Aside from that I don’t know of anyone that actually needs a 1200 watt PSU. Well, there are those that oversize their PSU’s so it does not have to work so hard in the hopes of extending its life and/or hit the sweet spot for efficiency.

    I’m guessing this newer HX is just a the HXi without the Corsair Link capabilities and a slight colour change on the logo/name. I could be wrong though, it might be a different design and manufactured by a different OEM.
