Customer Reviews

Corsair is THE best power supply manufacturer by far.
A. Mikulka
The cables are more than long enough to reach anywhere in my case (I have a relatively large case) and neatly sheathed to keep everything nice and tidy.
CS1
If you need a bit more power for an overclocked system, or multiple video cards this PSU is a great choice.

This is a great, rock solid power supply. This PSU is capable of handling almost anything that you can throw at it, except for some extremely exotic setups.

Most computers only consume around 100-150w, and even a high end computer might consume maybe 200w. That's why most OEM computer manufacturers put small 250-350w PSUs in their systems. If you look at online reviews of highly overclocked systems with multiple video cards (SLI/Crossfire) they consume at most about 500-600w. Anandtech (a very trusted hardware review site) in a comparison of the ATI Radeon HD 4890 and NVIDIA GeForce GTX 275 (google it) also did a roundup of other comparable video cards and some SLI/crossfire setups. Their review system was a Core i7 965 @ 3.2Ghz (non-overclocked), 6GB of RAM, and SSD drive, and X58 based motherboard. Idle power consumption ranged from 170-260w, and full load from 260-420w.

The point is you don't need a 1000w PSU even if you have a high-end system. The wattage race is long over. A good PSU from a good PSU manufacturer is all you need. For regular desktop systems, a good choice is Corsair's 400CX or Antec's EA380. If you need a bit more power for an overclocked system, or multiple video cards this PSU is a great choice. Also for consideration in this price/quality range are Antec's EA650, SeaSonic's S12 and M12 550w & 650w versions, and PC Power & Cooling's 650 & 750w versions along with Corasir's own 750w version of this same power supply.

This power supply is also 80 PLUS certified, which means that it maintains at least 80% efficiency across a range of power usage from 20% of it's capacity (~130w) all the way up to it's rated maximum. This is *very* good. Most off-brand PSUs only make about 70-75% efficiency.

This review probably won't speak to your uses for this item, but it will speak to the general bulletproofness of the Corsair. Sorry, I mean *BOMB*proof. I'll let the other 50 reviewers tell you about how this works in a computer, which I'm sure it excels at. I, on the other hand, needed at least 600 watts for a mobile DJ rig that was running off a gas generator, rolling around in 105 degree heat and nonstop dust storms. Please know, before we continue, that my conversion of the Corsair 1) voids the warranty and 2) is not entirely safe for the electrical newbie, so please don't go doing this unless you're comfortable handling live wires and have done your research on hacking ATX PSUs. I'll let you find that info on the internet and instead focus on the performance and reliability of the 750TX.

The environment this was in is knowing for destroying moving parts, devouring motors of all kinds, and generally ruining stuff in a hurry. It's the alkali flats you always see those car commercials filmed in the middle of nowhere, Nevada. Temps soar and the dust is so fine it gets into EVERYTHING. If you run a motor or any kind with a fan, the rule of thumb is to clean or replace the filter daily. It's hot and it's nasty.

The Corsair was literally buried in dust at times, baking in the sun, and it never stopped fanning itself (silently) or providing steady power. And we're talking hellishly dynamic loads here, too. Bass heavy music cranked to 11 will basically give you alternating zero to full loads. I blew up a lesser PSU doing this same thing before finding the Corsair ("melted, then popped" would be more accurate). This thing has gone for 20 hour stretches of this without a whimper. I blow fuses on the amps before this even gets warm.

I am extremely happy with this power supply. There are only two drawbacks (mentioned later). I love the power efficiency (80 Plus Bronze) so that it (1) doesn't waste energy, and (2) doesn't generate as much excess heat (which is where energy waste goes) so that (A) your case can run cooler with less heat contributed by the PSU, (B) faster with less heat (the enemy of computer speed), (C) quieter because both the PSU fan and case fans don't have to work as hard to exhaust heat.

It has very long cables to reach everywhere in my case. I especially like that they are long enough to let me run them with good cable management and don't have to be a spider web strung across the middle of my case, or risk banging into fans if not able to tie down to the sides. The cables are covered in a nice mesh material (common on premium cables). The wires are very stiff (explained in the video), which is a pro and a con, although mostly a pro. They seem very well constructed, but will take some bending to get things to daisy chain (drawback #1). But it is also nice that they hold their position so they don't flop around and get in the way. But might take more work to coax them into the position you want. The flip side of the long cables is that you will have excess cable, and seems like quite a bit (drawback #2). So make sure you have room in your case to nicely tuck bundles of them that you aren't using (see near end of video), otherwise they could get int he way of airflow. I'll take the length any day over having less to work with.

Although it is 650W, that is more about the maximum power it can crank out, but realistically you will end up using a lot less. My Kill-a-Watt meter says that I use 50.2W when on and idle, and spikes 90W during activity.
