2 out of 5 eggsMixed Review

Pros: Seemed to work steadily for about 1-2 years for me. No trouble, and even when it started displaying issues it still was able to provide power under load. It still is working, but after the "problems", I don't trust it.

Cons: Failed in January of 2014 hard: took motherboard , possibly CPU, and possibly a trickle effect that caused primary SSD failure. Computer just started rebooting under 350W load (measured via Kill-A-Watt at wall with Prime95 (loading CPU/memory) and the mfaktc (loading GPU)) and at 150W idle randomly at a low frequency until it suddenly increased in frequency.

Replaced motherboard and CPU and tested RAM, and since the problem was still occurring with new mobo. Replaced power supply with 430W spare and problem has not occurred in 3 months. Safe to say the power supply failed and failed to protect the other components from its failure.

Other Thoughts: I am a bit disappointed because while I have owned this power supply for close 4 years. I have only used it for about 1-2 years (or less) at most and there was never any significant load applied to it at any time.

I have had power supplies fail, but never take other components with them. I do not recommend buying this power supply due to this experience. Obviously I'm a little disturbed about losing $700 worth of components and having to pay $200 for new motherboard and CPU, but I'd say a 2-egg is well-deserved.

I can't 1-egg it, because hey, stuff breaks/maybe I got a bad unit out of the batch, and without knowing what particular failure occurred, it would be unfair to assume the design was bad. It also did work out of the box for a while within the warranty period. My personal indicator for expecting something not having a high likelihood of breakage.

Again, I am really disappointed that the power supply did not trip a fault circuit and prevent damage to the motherboard. The motherboard showed no visible damage but would not post with other power supplies anymore either. Without the motherboard, I could not verify whether CPU was dead or not. Not sure what happened to the SSD, but the SSD was working fine before the entire system failed finally that day.

NOTE: This was on a stock i7-930/x58 mobo with no overclocking.

5 out of 5 eggsStill Running Strong

Pros: Phenomenal build quality. All the bells and whistles I could ever need. Exceptional longevity.

Cons: Not modular, but I already knew that when purchasing.

Other Thoughts: Originally purchased this power supply in August of 2010. Nearly 4 years later it's still going strong, without a single hint of slowing down or stopping any time soon. Absolutely love it.

5 out of 5 eggsCorsair CMPSU-750TX

Pros: I bought 2 of these, one in late 2008(?) and the other in Feb 2009. They have both been used heavily on a daily basis for HOURS of non-stop gaming, video rendering for school projects and any number of other abuses we tend to dig up.
We turn our computers on and off 2-3 times a day and both of these units have always been there reliably.

We have run our computers with 4x 7200 RPM drives each (2 for system drives before SSD's and 2 for storage) and never had a single problem with these PSU's!

Wanted to buy another for my back office PC this year and am very sad to see they discontinued this model for a new version that does not seem to be as ROCK SOLID.

Cons: LONG cables (only a problem for smaller cases so not really a con for me).

Other Thoughts: Computer 1:
i7 920
Asus P6T
Asus GeForce 660 OC (2GB) upgraded from Radeon HD 6870
Kingston 1600 RAM (24GB kit)
Samsung SSD (upgraded from 2x WD 7200 in RAID 0)

Computer 2:
Intel Q9650
Gigabyte EP45-UD3P
Corsair 1066 RAM (8GB kit)
Radeon HD 6870
Samsung SSD (upgraded from 2x WD 7200 in RAID 0)

5 out of 5 eggsRock Solid

Pros: I've had this PS for going on 4 years. With the exception of the occasional power loss to the house, this PS hasn't been turned all this time.

Cons: I don't know about the noise issues since I keep my system in the basement. In any case, if there is a noise it hasn't affected the performance at all.

5 out of 5 eggs4 years and going strong!

Pros: Bought back in January of 2010 (price hasn't changed at all) for my first gaming PC build. I've never had a single issue with it and have been running my PC steadily since then.

Cons: None.

Other Thoughts: I don't do much on overclocking or stress testing on the PC and this is a bit overpowered for my build, so I imagine that helps longevity.

5 out of 5 eggsThe bold and the Powerful

Pros: I have had this PSU for over one year and it is a tank, it has run anything veI thrown at it and ran it with no issues....i have dual 6870s with an Phenom X6 overclocked and no issues so far.

Cons: Its not modular.....it was a pain to install this in my mid tower case

Other Thoughts: well newegg is out of stock but since this is corsair's V1 I would recommended their newer version which has less issues with the "smart fan"
