5.0 out of 5 stars Rock Solid Power Supply, July 5, 2009

By	Harvey Ramos "Geek" (Springfield, VA USA) - See all my reviews (REAL NAME)

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.

5.0 out of 5 stars 550 watts of power, February 15, 2008

By	S. Roomian (Upstate NY) - See all my reviews (REAL NAME)

This review is from: Corsair CMPSU-550VX 550-Watt VX Series 80 Plus Certified Power Supply compatible with Core i7 and Core i5 (Electronics)

Everything about this unit, the price and the Amazon service is first-rate.
Unit comes securly packaged first in protective padding, then some type of tyvek bag within a heavy box. Looks and feels well made. Plenty of leads and enough flexibility to connect to whatever you want. Fits right into a new HP case with no problems. Comes with its own mounting screws and black zip-ties to tidy up your installation.
I have been using this for a couple of weeks intermitantly, and so far it is working as it should. It is also very quiet.
Bonus - It comes with a cool sticker to put on your case.

1.0 out of 5 stars Supply failed after just 20 minutes, August 25, 2009

By	W. Jones (California, USA) - See all my reviews (REAL NAME)

This review is from: Corsair CMPSU-750TX 750-Watt TX Series 80 Plus Certified Power Supply compatible with Intel Core i7 and Core i5 (Electronics)

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!
