5.0 out of 5 stars Top performer 3 Mar 2009
Verified Purchase
I've just purchased this to replace the original PSU in my 3 year old
PC. It is of a sturdy, robust construction, switched, silent as described, and I can feel by touching my PC casing that it is running much cooler than it did with its original PSU. The PSU includes far more connections than I could possibly use (for anyone unfamiliar with the names of the connectors - see my uploaded photo). I use my PC heavily for video editing and I'm not sure whether it's my imagination or wishful thinking but I'm sure my PC is running faster following upgrading the power supply.

It has surpassed expectations and I highly recommend it to anyone looking for a replacement or upgrade.

5.0 out of 5 stars Great PSU 19 Jun 2007
I just brought this PSU as an upgrade. I didn't actually know but the one I was replacing was a Colors PSU too (400w tho).

It's great, quiet as a whisper, cools the whole pc and has all the connectors you could possibly ever need for ide/sata/fdd/Mobo/CPU/PCI-E card.

All in all its bloody amazing and at the price it's going I give it top marks.

5.0 out of 5 stars Silent by name, silent by nature... 7 July 2009
By Matt
After purchasing my new budget Zoostorm pc recently, I needed to replace the psu for something more powerful(it's only 300w)to provide for my brand-spanking-new graphics card - I didn't want to take any chances with overheating (espeically when I inevitably over-clock both my Intel duo-core E7400 cpu and Radeon HD4770 gpu!) so I reckoned that this 550w seemed up to the job.

At the time of ordering, there were 6 positive reviews on here which helped swing my decision, along with the attractive budget price. Atmittedly, I have read some shocking reviews for some of the other Colors psu models (only fair to mention that but then again, some really good reviews help make up for those!) but I thought i'll take a chance with this one at this price...and so far I have not been dissapointed:

This unit comes with just about every type of connector you could possible need for the average PC set-up (handily for me: including a 6 pin PCI-Express power connector for my new graphics card) - the main motherboard connector having a versatile 20+4 pin configuration (I use the full 24-pin option).

For the average person like me who is not espeically computer-savvy but just about gets by, fitting this psu was a doddle - I just did the obvious thing and copied how my old psu was connected (with the simple addition of sticking the 6 pin connector into my newly fitted graphics card as well). All those connectors/cables can make quite a tangle if your pc case isn't espeically roomy but a bit of perserverence and you'll be fine!

2.0 out of 5 stars weak candidate 24 Nov 2010
Verified Purchase
I assembled 4x PCs over the last years using this item. On the first look it seems good value for money. In 3 of my PCs it worked silent, in one was noisy.

My last build was 2 years ago using a Gigabyte GA-M770-UD3 + AMD5000DualCore + ATI 3650 + WD 320 GB SATA 2048 GB Memory 800Mhz - Samsung DVD drive.

After 1 I had increasing porblems with the DVD drive, which sometimes wasn't detected. Replaced it but weeks later the same happened again. Over the last 3 months my PC just stopped - black screen and rebooting - crashed my first 500 GB HD. Replaced HD - later the Motherboard. You would think a 550W PSU is sufficient for this constelation - but when I reassembled the PC and nothing worked I realized that it might be the PSU. After doublecheckeing each step, I checked the PSU with a Voltmeter - and it produced nothing. Checked it it against another PSU Gold from my older PCs. Nothing worked the Voltage on this one was low, worked only with my old Athlon2800.

Conclusion - it might be a tempting offer - but if you use it for DualCore or QuadCore with and some decent components this PSU is just to weak. I recommend going with branded PSU with a proven 20AMP output.

3.0 out of 5 stars Nice product but incomplete !! 8 Nov 2010
Got on time, good quality but on the advert it was mentioned that there will be a power cord which was not inside, so had to order separately, so if they clearly mention, it can save time for other people to wait and then other cable later on.

4.0 out of 5 stars Great PSU 7 Feb 2010
By Harry
This is a very good PSU i only have a few problems with it, the specifications in my review are for the 550w PSU as i read a review previously that had the specifications for the 400w and below models

- it was well packages in plastic and the cables were not twisted together
- two SATA connectors
- one 24 pin connector able to become a 20 pin connector easily
- one 6 pin PCI-E connector
- one 4 pin + 12V connector
- one floppy connector
- four molex connectors

- the SATA cables are connected so you need an adapter to connect most of you SATA units to the PSU
- it doesn't come with any connections pins so i was having to juggle around with the screws that came with the case

Bought this to replace a dead power supply and it does the job perfectly. Not too noisy and has ample connectors for all the bits and pieces inside the PC.

Easily replaces my old power supply. Easy to swap over - especially with instructions provided. No power cable supplied - was space in the box, so was it removed?
