solid performance..

purchased this supply about 14 months back and has been great, untill mid week when it died..go onto OCuk who explained a 12 month warranty was given by them so was advised to go direct to Corsair, who within 2 days had issued a RMA and are awaiting me posting it off for a replacement.

overall, the PSU has been a good one, very quiet and has server my rig well.
i would recommend one of these as corsair throw a 5 year warranty on lower models and a 7 year on the higher ones which to be fair, you cant complain about!

Amazing performance, but...

Got this PSU over 12months ago, this is what it was running:

Asus P6T x58 M/B
6GB OCZ memory
i7 920 2.66ghz cpu, stock fan
5580 V/C
2x 500GB HDD
1x 40GB SSD

The PSU worked so reliably for just under 12months, Christmas eve 2010 it died.

Customer services told me I'd have to wait 28 working days for replacement, no PC for that long would have killed me. Luckily they decided to send one out around 1.5 weeks later.

While the PSU worked it was unbelievably reliable, best one I've used.

But due to it dying and even though the unimpressive customer services shouldn't count, it will lose a mark because of it.

My system was never overclocked btw.

Also been using ocuk for years, spent thousands and have never had any problem with customer support, but this episode left a sour taste in my mouth.

Will give them one more chance, as I think their products, prices and delivery service are second to none, and always have been.

Sort your returns policy out ocuk!

Fixed my memory, Sir

i decided to get this psu as an upgrade from another highly branded one, when i installed a new graphics card.. and well it fixed the memory problems i've been having with my asus rampage board too; only detecting the full 6gb via cmos reset, until reboot. if you've been having problems with memory being fully detected and you've run memcheck on each stick and they're all fine, and the cpu socket pins are all ok, it might be worth upgrading your psu to a decent one such as this corsair.

For those that are wondering, the psu has two pci-e 6pin cables but they also have extra 2pin attachments to make them a full 8pin. Although it is SLI ready, for the newer cards, you may want to look for a much higher powered version or you're going to have to make use of 4pin molex to 6pin pci-e adapters, but they usually come with graphics card anyway.

Just got this to fix my my PC not turning on, as my old PSU died out. Not only did it fix it it also fixed my standby issue of my system turning off when switching to standby, I could have sworn it was a mobo issue.
It has loads of connectors and is backwards compatable with my current mobo which has a 4 pin mobo connector instead of the issued 8 pin, but you can detach them. The only thing tricky installing this is the ammount of cables, but you get a few tie wraps so it's cool.
Its also quieter than my old cheap one so i'm happy. This was and is a wise investment I think.

Sweet PSU, sour mains cable

Excellent compact PSU, has loads of connectors, smaller than my old Tagan.

I'd give it 5 if Corsair supplied it with a quality, _locking_ IEC cable, not the loose, flakey cable supplied.

It is really annoying to face mystery power lose or crashs because the IEC connector is not a secure fit.

I don't understand why locking IEC cables aren't supplied as standard for PSUs, maybe OC could supply them as an upgrade part?

Does the job brilliantly

This should instantly be your choice of power supply if you are not looking for high-end sli or xfire.

Enough said?
Perhaps not: This power supply is reliable and is capable of supplying excellent amperage on the 12v rail - certainly above what most other 650W psu's can. The fan is also very close to silent. I will be choosing this and similar Corsiar power supplies for all my builds for some time to come.

This PSU is truely brilliant, it runs very cool, is quiet, gives out solid dependable power, and the cables come ready sleeved!

Pity it's not modular, but at that price, who's complaining. :P

Amazing Quality

Got this two days ago, bit slow on the delivery (an extra day) but am super pleased with this, my first PSU upgrade :)

I'd heard great things about Corsair and from the moment you get the box they're obviously true; after opening the awesome looking box it's held in two anti static pads and get this: a drawstring bag xD

It installed sweetly, it's super quiet, the cables are lengthy, quality and easy to plug everything into... This was also my first upgrade on my case, so the whole thing went perfectly! Thanks OCUK and Corsair PSUs = 10/10

Great PSU

Had about 4 PSUs over the years including enermax and hiper. I was surprised at how quiet this PSU compared to my previous ones, no humming or vibrations and it stays very cool after being on 24/7. Even had a few power cuts in the first few weeks I got it and I had no problems!

It has the build quality of top of the range PSUs at an amazing price too.
