  I do not vote.
  
  The PSU doea NOT have genuine 550W.Spec of the PSU is poorer than the 425W Hiper.
  I would never buy it.

  Rail Stats:
  
  +3.3V +5V +12V -5V -12V +5VSB
  28A 35A 20A 0.5A 0.8A 2.5A
  

  
  
  Stats from main page - which calculating in my head - look more like 522.4W.

  Purchased this about 8 months ago when I built my new PC...
  
  Take this advice:
  
  DONT CUT CORNERS WITH THE PSU!!!
  
  Had to be sent back 5 times, yes, 5 times, because it couldnt keep up with a dual core processor and an 8800gts.
  Buy a decent make PSU

  At the end of the day most PC's don't need more than a 350W-400W PSU unless you are running multiple graphics cards (if you need to ask then you aren't). Don't buy a cheap high rated PSU cos they may use very poor quality components increasing the risk of them failing and potentially taking out your whole system. You are far better to spend similar cash on a basic branded one such as these:

  Oh and definitely avoid the "free" ones in cases costing around £20 like this:

  I hate the way these PSUs use the word 'silent' when they clearly have fans.
  
  Silent = 0db - in my opinion!

  Wow.... a thread where people who say "You get what you pay for" aren't getting mobbed by people who think that 50p is too much to pay for a PSU :)

  Buy a quality PSU instead of a cheap one... Generally speaking you should never buy any PSU claiming a high wattage at a low price, especially if it isn't from an established and reputable brand

  Well, i'm running an even cheaper PSU at the moment...the 450w Sumvision one - two years on and not a single problem, and this PC is more or less on 24/7.
  
  I've used them in 2-3 PC's i've built for people too (same specs as yours) and none of them have had anything go wrong. It's the PSU's that come with the cheap cases that I don't trust...after exploding in my face n' all :thinking::w00t:

  
  
  Personally I think you have to spend a little more than that to get the quality of electrical components that you can rely on for a large number of years. Whilst most people won't have a problem with the cheaper supplies, there will definately be more poor quality control ones blowing up systems and potentially losing all data, etc.
  
  The reason even the cheap PSU's tend to run OK is largely because they run them so far under capacity. A normal dual core system with a decent GPU such as the 8800GTS will only consume about 200W power when running at it's peak, most of the time it will be low 100's. As such you are never really testing the PSU up to the rating.

  have to add my 2 cents in on this one as well. I bought this a while back. Simply not good enough to run a Dual Core E2160 and a 8800GT. Lesser systems only i would guess!

  Scan do this 700W FSP PSU with 83%+ efficiency & all modern connectors for £27-30 from time to time. I'd go for that anyday over this.
  
  Edit: The connectors are as follows...
  4x Molex
  4x Sata
  2x 6pin PCI-E
  2x Floppy
  1x 24pin motherboard power
  1x 4pin CPU power

  Get something quality. The Seasonic 430w can be had for under 40 quid now, and is basically silent to boot (120mm fan).
•

  I doubt whether it is what I would call silent. It might be reasonably quiet.

  molex -> sata adapters are fairly cheap - that's how i sorted the problem :thumbsup:

  
  
  A SATA power cable will supply 5V, 12V and 3.3V but a Molex connector is missing the 3.3V. I believe that few sata drives use 3.3V so it shouldn't be a problem. Anyone know different?

  I'm a system builder of many years and couldn't have put it better myself!

  To the best of my knowledge this is correct. The 3.3v was for future developments rather than existing ones and helps with the 'hotplugging' feature of SATA drives, but drive manufacturers seemed to have dropped off support with the current crop of available drives. However, I'm certainly not claiming to have expert knowledge on this and would welcome other people's contributions.

  Quite true. The thing is just like my father in law's PC when a PSU goes it can take all of your internal components with it so saving 20 pounds or whatever can cost you a few hundred pounds if your PSU goes.
  
  The other thing is that the better the PSU the more efficient it will be which will save you money on your power bills.

  I have a Supermicro twin xeon based server running four threads and sitting quite happily on the (Supermicro) 430W PSU it came with.
  
  However, I am about to swap a RAID array into this one - but think its time to upgrade the PSU.
  
  In the past buying cheap PSUs and shoving in Papst fans has worked well - as invariably failure follows fan failure.
