Coolermaster RS-550 power supply
Another power supply review is coming up, tonight we will look at the Rs-550 PSU from Coolermaster. We know that there are many good power supplies out there and it’s hard to compete with Antec, OCZ etc but I know for a fact after that we reviewed Coolermasters 450w PSU that it did perform very well so I beleive this will be a better version even than the last one. We will compare it to OCZ Powerstream and the older 450W Coolermaster PSU.

Coolermaster has always been very good about packing their products and this is no different. The PSU is well protected in the box and with a plastic sack around it. The accessories are also well placed to prevent the PSU from moving around in the box. On the outside you have a picture of the power supply itself and on the back you can find some more small pictures with specifications.

Something neat with this product is that a small analog display is included so you can see the power usage. THis display lights up with a nice blue shine so you can see it in the dark also. Other included products are screws, manual, 24->20 pin adapter and the power cable itself.
