does it's job

used it for 1.5 year, replaced my old 400W Noname.
It works quieter than old one, if works loud, check temp inside and take a look at vent, maybe sucked some paper clip.
Wiring - nice, long, coated...
Feeds everything i need and fan really helps to cool inside environment, but..
They have long warranty (that why 4 stars)

V Stabilisers do not work as expected, after pluging in some USB device, you can have unexpected reboot. Noname handle it better :/
It died after 1.5y use, and died only 12V rail. No OC, GF 460GTX, 4 RAM modules 2HDD, 1DVD-ROM. Noname handle it w/o GF.
Bought on sale, but not sure, that value for this is correct.

I got this with a bundle (Storm Scout and GX650W). It's very quiet, probably the quietest thing in my case. For how it performs, here are my specs:
AMD Athlon II X4 620 2.6GHz @ 3.5GHz
AMD Radeon HD 6950 2GB
Corsair XMS 3 8GB 1600MHz
WD Caviar Black 1TB SATA-III 6Gb/s
Seagate 320GB 7200rpm
Asus M4A89GTD Pro
Usually, someone would go with a 700-900W PSU but this is around perfect.

Good Value

Been using one of these for about a month now - coping fine and plenty of cable but heck its loud! Loudest psu I've ever had anyway - Overpowering all the other fans in my system, and no fan control...If you're looking for a quiet unit look elsewhere, apart from that its good value so recommended.

Almost great

As others have said it is very good with coog cable lengths for a full size case but there is no fan speed control so use a soundproof case if it's sitting under your desk.

Good Enough

Service from OCUK was top drawer as usual, delivered when it was supposed to be and good tracking information.

The PSU itself is, as the title suggest, good enough. It's solid, it has 52A of power to spare and it comes with 2 6+2 pin GPU adaptors. I've used Coolermaster PSUs before so I'm sure it will be reliable over time.

It only gets 4 stars for one reason; the product description states "Ultra-Silent operation". It isn't. It's not loud, but I've used quieter PSUs and it certainally isn't "Ultra-Silent".

Still happy with the purchase, I'm sure I will get a few years of solid, trouble free usage from it.

Good, solid stuff.

First time buying a PSU separate from the case, this put me at ease. No nonsense, just a solid PSU.

Baroman 2010-12-30

Good product

I want to start by saying this is a good psu for everyday use, i am usen this psu to power my gtx 460 talon attack, it does the job well with 2 pci-e cables all nicley made etc.

i want to say thou, i had a rarther big problem when i got the product itself, the box came bashed up and dented all over! due to careless packaged! :( and when i opend it the psu itself was bent at the edge and the case was damaged due to what i see as bad manufacturing, it had a smooth slash on its edge and it was out of shape, thankfully it just needed prying back to shape, it works fine, still not acceptable :(
