Few things to look for in the specs:

First of all is the certifications. SLi means it is SLi compatible and has the right connectors. It can be quite deceiving since it very well may not have enough power to power two nVidia cards. You have to understand that power is still an issue even if it’s “Sli certified”. General advice would be having a power supply that is used to about 70-80% of it’s capacity. A great tool for this is this calculator. 80-Plus standard certification means it has at least 80% efficiency at loads from idle to 100%. This means that your power supply does not waste too much power at any given point. As you can see under “Efficiency” it says “85%+ Typically”, but that doesn’t mean much without a certificate such as 80Plus since “typically” is very flexible word. Protections are to save your hardware during over-voltage, under-voltage, over-currect etc. Silent Pro M covers all the important ones without a doubt.

This power supply also support up to 264V automatically, meaning our European guests can use this power supply no problem.

One thing here to note is the inclusion of Max output capacity and regular output capacity. Since there’s no requirement for companies to put either one on the box some companies may go as far as to put max out put and get away with it. PSU’s can’t hold Max output for too long and failure is imminent. It’s always good to know if that big flashy wattage number they put on the box is max or regular.

Not the most well organized package but it holds the PSU inside tightly but with only one side Styrofoam for protection. It should not be an issue for delivery.


  • 1 – 5 pin to Peripheral+Floppy
  • 2 – PCI-e 6 pin to PCI-e 6+2 pin
  • 2 – 5 pin to SATA
  • 1 – 5 pin to Peripheral
  • Power cord
  • User’s manual CD
  • 2 – Rubber mounts

It has all the connectors you need. Rubber mounts are a nice addition to the box. These will keep the rattle noise to a minimum in case of tight fittings in your case.
