Product Description

The Corsair Builder Series of PSUs are designed for worry-free compatibility for your home desktop PC system build or upgrade. With features usually reserved for premium power supplies, it’s a great choice for systems where continuous and reliable power delivery and low noise are essential.

From the Manufacturer

CX Series power supply units are an excellent choice for basic system builds and desktop PC computer upgrades. CX Series PSUs are available in a variety of power configurations, and include features that are normally found only on premium power supplies.

Overview

CX Bronze Series PSU
Reliable and Compatible

CX Series is built and tested to strict standards for trouble-free installation and smooth operation.

Low Noise

The 80PLUS Bronze certified efficiency and clever fan design allow for little or no detectable fan noise during regular operation.

Good Looks

The matte black finish, black-sleeved cables and black connectors help give your system a restrained, high-tech look.

Features

Corsair Engineering and Quality Control

Every Corsair power supply is designed by our California engineering team and built to our exact specifications. The same care that goes into the design and testing of our renowned high-power enthusiast power supplies also goes into the CX Series, because you need confidence and reliability regardless of your build budget.

Ample Connectors and Long Cables

Long cables make CX Series suitable for installation even in full-height tower cases, and the generous cable count allows you to power multiple components and storage devices.

Large-Diameter, Thermally Controlled Fan

Once you’ve installed a PSU, you shouldn’t have to think about it. Employing a thermally controlled fan makes the CX Series quiet at idle, and the large diameter reduces noise even when you’re pushing your system hard.

Black Goes with Everything

You’re building a PC, not a battleship, and appearance counts. The matte black finish and all-black sleeved cables and connectors help give your system a high-tech, restrained look.

Customer Reviews

Installation was easy and everything works just fine.
M. Makuski
Don't buy a cheap brand PSU, a nice one by a good brand like Corsair is definitely worth the few extra dollars.
Derek H.
I has a very nice design and cables are long enough for any computer case.

When it comes to Power Supplies, never be stingy and spend a good amount on a solid one. Corsair is one of the most well known PSU companies and their supplies are up top in terms of qualities and specs. When it comes to buying a power supply it is important to remember that two things are needed:
1. Enough watts, look up the total watts of everything you own and buy a power supply that is at least 100w more so as to give you enough headroom for upgrades or overclocking if thats your cookie.
2. Enough Amperage. This is veryyy important. The +12v rail is whats important as most modern cards require a minimum of 25A on a single rail. Dual rails are also nice if they are each at 25. For example, my XFX DD Black edition Radeon HD 7970 will not run on my old psu. It was a solid Rosewill 600w psu which had more than enough watts to run it, however, the thing maxed at 35A on both rails together. The minimum needed for the card was 36. This PSU, has 750w and the following ratings on each charge: +3.3V@25A, +5V@25A, +12V@62A, -12V@0.8A, +5VSB@3A.
+12v@62A is excellent for the card now. This also gives me headroom if any future parts require more Amperage or watts. The price is seriously perfect here on Amazon. The power supply retails for 100 bucks on other sites.

PROS:
-Great price
-pci express power at 62A (+12v)
-sleeved components with the cables reaching full tower( they arent short cables so it works on an NZXT Phantom and an Antec twelve hundred tower.) Both of which are full towers.

This is a great deal for an 80 Plus Bronze certified 500W power supply. If you are running any machines 24/7 on power supplies that aren't 80 Plus certified, let alone Bronze, Silver, Gold or Platinum, there are a good amount of power savings to be had. For the layman, anything labelled 80 Plus certified means it is 80% efficient at 20,50 and 100% loads. Bronze, Silver, Gold and Platinum are even more efficient, respectively.

I had thought that I had tuned my file/media server/video encoder to be pretty energy efficient. It consisted of an i5 2500k, 16GB DDR3, no video card, 5 WD Green drives, 3 WD Black drives, one SSD, two internal PCIE SATA 3 extenders, and a BD-R drive, running Win 7 Professional 64. It consumed about 62 Watts at idle, and 73-80 Watts under moderate load, when streaming or transcoding high bitrate 1080p video. Not bad, and about the same as leaving a single incandescent lightbulb on. All of this was powered by a several year old sturdy Thermaltake Purepower 500 (W0100RU). The old power supply was not 80 Plus certified.

I got this Corsair 500W 80 Plus Bronze power supply because the price is fantastic at around fifty dollars, and the old power supply was getting loud. I wasn't expecting phenomenal power savings, but according to my UPS wattage reading, this power supply is kicking butt! My file server now idles around 40W and operates at 56-63W under moderate load. These are big, big savings. I had no idea my old power supply was so energy inefficient. Considering the higher electricity cost in Southern California, this power supply will save me about $4 each month, possibly more if it helps prevent me from crossing into higher Tier level payments.

Upgraded my graphics card to a new one (GTX 660) and needed to upgrade my power supply as well. This seemed like a well rated, well priced appropriate option, so I bought it. Was easy enough to install, runs quietly and effectively, has lots of extra hookups to handle whatever I might have in my system.
Only complaint, which is really more a lack of foresight on my part, is that there were no actual instructions in the box. The one thing that would have been super handy to know is that if you have a 4 prong ATX12V motherboard plug, you have to take the 8 prong plug this comes with and split it in half. They clearly explain this on their website, but that is harder to access with your power supply out and halfway replaced :). Otherwise, great product, great value.

Most of the power supplies are under powered, as I learnt from extensive online research. After my old PS would power down, power button would do NOTHING. Ordered this baby, and voila, this unit is more than capable of handling the system. To give some perspective, my old PS was abt 350W max, and barely on the borderline to power the unit (Actually no additional components were added since original purchase)...This new unit is 600W, and very easily capable of handling the load. Highly recommend!!

Excellent PSU. The right amount of power without overdoing it. Lots of connectors with a lot of options for the mobo connector or the PCIE video connectors...yes there are two of them for the higher end GPU's. Nice metal case with great ventilation and a strong but quiet fan. Have made this PSU the de facto standard for all my computer builds. Highly recommend.
