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 doesn't just make a difference in your electric bill (not much, but every bit helps), but it also means the PSU runs cooler since less energy loss during conversion from AC to DC. Generally speaking the 80 PLUS certified PSUs use better quality components to achieve the higher efficiency which means they are less prone to failure than the other cheaper brands.

In addition to having quality components, it also looks very good in the case. A very dark grey matte finish accented by yellow and black markings. The cables are long enough to reach pretty much anywhere. This is in my Antec 1200 full-tower case, which has the PSU at the bottom. The 8-pin motherboard power connector has plenty of room to reach the top of the motherboard. However, I had to run the cable the "normal" way over the video card and past the CPU fan since it was not long enough to feed behind the motherboard tray as I was hoping. Then there are 2 cables with 4 SATA power plugs on each, 2 cables with 6-pin PCI-e video card cables (each having an optional 2-pin attached for those video cards that require 8-pin power), and 2 cables with 4 regular molex plugs each.

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. It's actually never gotten warm, other than being in the sun, which is also handled without a problem. Using indoors in regular temps is a walk in the park for it, so I've also converted it for use in home theater without an issue. It's provided enough power to blow fuses in the amps I'm using, which means it's peaked at around 1 kilowatt of power. Let me repeat that - it has delivered A FULL KILOWATT OF POWER, albeit briefly, and stayed in one piece. That's insane!!

Think of this like extreme conditions testing for something you'll never use in those conditions, like when they test helmets by smashing them with battering rams. Normal computer users out there will *not* have a reliability issue with this item, I promise. I can't imagine what the high level Corsairs could do - you could probably power a small town with them.

Corsair is THE best power supply manufacturer by far. I believe this particular model has a MTBF (mean time between failure) of 100,000 hours, which is insane. I am running a GTX 295, overclocked core i7, DVD burner, 10k hard drive, and 6 gigs of 1600 Mhz Ram with ease on this power supply with breathing room. When I get my other GTX 295 and hook up the Quad SLI, add another hard drive, blu-ray burner, and 6 more gigs of ram, I will need a 1200W power supply and I really wish Corsair made one. The only real "con" is that it isn't modular so you need to have decent cable management to keep the airflow tip top. Buy this, you won't be disappointed.

This is a monster of a P.S.!!!! I have it connected to an MSI NF980-G65 MoBo and it worx flawlessly - to users with other poor ratings, do your research b4 u buy - it was a known issue between ASUS and CORSAIR, ASUS's support problem:they fixed it now!!! This thing easily powers my PhenomII 965, 2x EVGA GTX275 in SLi, 3x Hard Drives, 2x BluRay/DVD Drives!! With 6x 8-pin PCI-e connectors I have the expansive possibilities to add in a separate PhysX dedicated nVidia Card! With this particular setup i have, all 3 PCI-E slots have 2 8-pin connections to power pretty much any video card combination out there 2day!!!!!! The cords are nicely wrapped, and your almost future proofing yourself with all this power and the xtra connections!!!! These TX Models operate at low temps and do not get loud at full load on gaming rigs even after playin for 5-6hours!!!! The StainlessSteel Etched Logo for stickin on ur case is pretty sweet, fancy velvet bag it comes wrapped in is beautiful too!!! probly woulda made it 10 bux cheaper tho ;) I have been building PC's since the first 300mhz Celeron came out and these are a very nice P.S. compared to most bein made out there! This is the 3rd CORSAIR TX power supply I've bought, I also own 750 and 850 models - installed on my other ASUS A8N32SLI-Athlon4600X2-9800GTX in SLi & ASUS M4A79T-PhenomII955-ATi5770 in CrossfireX!!

I purchased this Corsair 750 Watt supply at the end of June 2009. I ordered a new graphics card from another vendor at the same time and the card was DOA (Broken right out of the box). I just got around to ordering a better card (ATI/Radeon 4770) and it is due to arrive tomorrow, Aug 26. I finally installed the power supply this evening, Aug 25, so everything would be ready for the new card. The supply worked for 20 minutes and then shut down. So I reinstalled my original supply and everything is OK. I'll be sending my Corsair back and try another one. I am 0 for 2 with this upgrade. An update will follow.

Update: Aug 28,
I returned the dead power supply to Corsair in Fremont, Ca. (Just a 45 minute drive from where I live). They exchanged it no questions asked. (I happened to get the one that made it through quality control only to have it fail 20 minutes after installing it. These things happen). The supply fan is very quiet. Much quieter than the ATI 4770 fan, which is fairly quiet.
I would now change the "STAR" rating to 5 Stars if I could. And 5 STARS to Corsair for their customer support!
Thank you Corsair!

Corsair remains Corsair. Silent, powerful + 5 years warranty. Am using it in Europe, 220V - just great.

This is quiet power supply. It's not fully modular but the main cables that are generally used are the permanent cables while cables such as additional GPUs are the modular ones. Has more than enough power to run two GTX 560TIs. Cables are stiff but still easily routable to components. Comes with nice velvet bag which was nice for extra cable storage. After using this in my gaming build I will be buying the 550M for another PC with a failing/noisy Antek PSU.

I got the TX 850M PSU and the "M" tag is a complete joke.

There are only 4 modular connections and the rest come in your standard mess of power cables.
Other then that it's a good PSU and can handle my system really well.

My only grip is that:
The "M" tag is completely misleading.
The images in Amazon don't preview the back of the PSU to show you this.
The specifications don't mention the amount of modular connections.

I know there are a lot of reviews on this PSU but I didn't see one that talks about the modular version.
Well I got the modular version, and it is great, I was tired of all the cables hanging around the case preventing good airflow inside, this PSU was the best choice, I'm a regular gamer so I have 1 Vid card, 1 optical drive, 1 Hard Drive, and with the modular version I save up A LOT of space since I don't need that much

I use this power supply with a Core i7 system on an Intel X58SO motherboard, a dual slot Nvidia 8800GTS and every PCI slot filled, 3 DVD burners, 2 video cards running 3 22" monitors. I draw about as much power as possible from this power supply, and it works just fine.

It's very quiet and has been completely reliable for me. I don't know why, but the thing doesn't hold dust like previous power supplies I've used. Overall, completely satisfied and definitely recommend this model for purchase and long term use.
