Good built quality. Good value for money. But if you want to use multiple graphics card and HDDs then go for 600 W model.

This is the best PSU I have purchased till date. Fantastic performance & yet very silent.
Always buy this CX version than normal 500/550W PSU since this is rated for atleast 80% efficiency.
While buying any PSU, including that from Corsair, don't look just at wattage but efficiency.

Budget PSU

I bought CX series this time because my VS series got burnt out after 2 years of use.
This PSU is 80 PLUS: Bronze so you don't have to worry about your electricity bill.

My config-
Asus P5G41T-M-LX MotherBoard
Intel Core 2 Duo E8400 Processor
4 GB 1033mhz DDR3 Ram

Best CPU within budget with Corsair Reliability!

Prime reason for most of the computer parts giving up over a time is use of poor quality power supply!

The corsair one is best for daily use with no extra peripherals attached to the MB. If you have extra graphics card make sure that your power requirements match up with this PSU.

Very Good

Bought it in 2012 from flipkart. Working very fine after 2 years. The fan is very silent. Very good at this price range.

EDIT: Updating on Apr 16, 2015. It can run a GTX 960 without problems unless your other devices are not power hungry. I am using it with GTX 960 with this setup - CPU, 2 …

First to review

Fine PSU

I have been using this one since the last 6 months and haven't faced any issues. The PSU package reeks quality, even though this is the base series of corsair(builder series). All necessary components to install this PSU in the PC cabinet are there in the box.

There are many good reviews for this model on the net so i won't go into that detail.

The one thing to look for when buying a PSU is the +12V current output. The higher the better. The cheap PSU's that come packaged with most systems and cabinets will have a low current rating on the +12 V rail. These have to be avoided as this rail

A word of caution to all users

These PSUs have Active PFC are of good quality, no doubt, but there is an annoying problem which arises because of the UPS used. I learnt about this after two years of experience.

(what follows may be a bit too technical)
I had a Cooler Master Real power Pro 460W Power supply (bought in 2009 Dec) with Active PFC, and the UPS used was a Numeric 600VA normal UPS which supplies a MODIFIED SINE WAVE (stepped sine) during power outage. Most cheap UPSs give a Stepped sine wave. This may cause the power supply to SHUT-OFF immediately as soon as the mains power goes off, or some annoying humming soun

Good PSU

I bought it 10days back. Working fine with no issues. Quality is good(Thick and heavy metal). Cables comes with tick cover.
6 SATA power pins,
3 legacy power pins,
2 motherboard power connectors(24+8 pins).
One PCIe X16 power connector.

Nicely sat in my coolmaster elite 311plus cabinet with bottom fan.(fan is silent).

430 wattage is enough for mid range PCs(If you are not using 2 Graphic cards with SLI or CrossFire technologies or not over clocking).

I am using it with 125wattage processor and midrange Radeon graphics card. Working smoothly.

Finally thanks to flipkart for their quick d

Absolutely the best for this price.

If you want to purchase a quality power supply for your office or low-end gaming machine, look no further. Despite Corsair using the components made by Channel Well and not Seasonic, the unit delivers amazing performance as tested by many hardware review sites and blows the competitors such as "400W" (quotes because they EXPLODE when you draw 400W from them) Huntkey PSUs out of the sky for just a bit more money. It's quiet, cables are sleeved, it looks good in your case. In a very unlikely case that the unit breaks, Corsair's warranty policy is replacement, no "repair" BS.

Received 2 Dead PSU's in a row

This PSU arrived dead and I ordered for a replacement. Flipkart amazingly shipped one - no questions asked within 3 days. Even this one was dead! I don't know how and why this could happen since a lot of people here have a working model. I can't rate this model since I never got a chance to test it but I'll go with a generic 2.
Also Flipkart refunded my money into the e-wallet allowing me to purchase something else so that's cool

Dont buy Corsair

Dont buy Corsair. I bought this PSU before 4 months and now smoke comes out like my PC is on fire. Contacted their support for service. They said there is no service in India and I have to send this to Hong Kong and they will look into it. It costs well over 1 K for that and they wont pay that fee. Support is horrible and you just have to through it if it doesn't work.

A value for money power supply.

I Got this PSU some days back from flipkart and i must say its great.

Pros :
1. Value for money, its difficult to get a 80+ certified PSU at this price.
2. Very silent, it cant even be heard.. even after long hours of gaming there is no screeching or whatsoever.
3. Can Handle a modern GPUs with ease.. this will be more than enough for anything up to a HD 6870 or a GTX 560 (im using it with a 560)
4. Good quality nylon braided cables.
5. While people complain the PSU if often DOA, i did not have any such problems, the PSU was packaged properly and works great.
6. Corsiar has great customer su

Amazing PSU

Got it delivered today as promised. Excellent service as always.
Now, this PSU is best PSU under 500W section, it has 1X12V rail that supplies up to 336W for CPU/GPU. If you have PSU under 500W then I would suggest to go for single 12v rail for better load performance.
The product delivered is a UK product with UK power socket, so you will need to get an Indian power socket adapter.

It is a recommended product by various top reviewers websites like tomshardware, jonnyguru and many more.
It has 90v-264v input, so no worries about voltage fluctuations,
It can even power a NVidia 560ti with a de

A good PSU for an entry level gaming rig

On arrival last week, I found that the casing on one side was bent. But anyway I installed it in my cabinet without any problem and have to admit that it is indeed a good a PSU for an entry level gaming rig.

1. Sturdy built quality for an entry level PSU.
2. The fan is really silent on no load and has good exhaust capability, have noticed my CPU/GPU temperatures under normal load got decreased by 5-6 degrees, immediately after installing it.
3. Sleeved neat cables with reasonable length.

1. The plug of the mains power cable is not compatible with normal Indian sockets. Just a
