Excellent quality PSU. No issues with cable length, although I am using a relatively small ATX case.

Great for the price!

Bought this while it was on offer recently to power a fairly average gaming PC (Intel Xeon E3-1240V2 with 8GB Sapphire RX 470 graphics, 16GB Crucial Ballistix DDR3 1866 RAM, 250GB Crucial SSD & 2TB Hitachi HDD).

It does the job just fine and does it quietly too! It's a good quality unit as you'd expect from Super Flower with plenty of connectors and good length cables. Perfect for a mid-range gaming rig!

The efficiency rating on the box is a little less than what is stated in the OcUK description... The box says 87%, 90% and 87% at 20%, 50% and 100% loads (barely scrapes the gold rating). It doesn't say however if this rating is at 115V or 230V, but I'm going to assume these are the 115V values and the 230V values should be slightly higher.

Perfectly happy with this unit and nothing really to complain about considering the relatively low price. The connectors seem strong enough to me so maybe the other user reviewing it had a bad unit?

Great service from OcUK as usual. Thanks!

Good quality PSU

Very happy with this PSU. Plenty of connectors for a mid range build, good length cables. Very quiet and quality PSU.

Quality PSU

Really impressed with the Superflower brand. This is a great, high efficiency PSU.

Comes with enough cables for all your components. One thing is to note is it has 2x 6+2 pin gpu cables. (i.e. it will power one dual power high end graphics card) But with 550W you wouldn't want to try to power 2!

I run this with a overclocked i5-2500k, and a overclocked MSI GTX 770, couple of ssds, hdds, and a few fans/pumps. PSU is easy enough for the system due to the high efficiency :)


Quiet, efficient but weak power connecto

Ordered this for a build and I am generally pleased with it. Its fairly quiet, efficient and it fitted in nicely with the remit of my build. Works well with my i7 system with an R9 280X installed too.

My only major complaint is when running one of the SATA power connectors to one of my HDDS the connector sheared in half with no input from myself, just snapped and fell off the drive. There was no tension in the cable at all and it was cleanly inserted.

Otherwise its great!


Great psu but short cables

Hi, the spec and performance of the PSU cannot be faulted. The unit is quiet and easy to install with enough power and connections to run quad core cpu dual pcie power graphics card, 2 optic drives, 5 hard drives and 7 fans.
The only issue i have to stop it being 5 star is the 6 pin pci power for graphics cards is to short to be run discreatly in a case with a top mounted PSU, if the psu was in the bottom or the cables were modular (so you could get longger ones) this wouldnt be an issue.
