Well - I would definitely say you need to replace it
The wattage depends on the total amount required by all the components PLUS of course a small safety margin AND when that is calculated - it must be capable of supplying that all the time NOT just the maximum it can supply.
Use this - you do not of course have to buy Corsair - http://www.corsair.c...earn_n_explore/
See thisPeak vs. Maximum Wattage Output
This is the first consideration when it comes to looking at power supply specifications. The peak output rating is the highest amount of power the unit can supply but this is only for a very brief time. Units cannot continuously supply power at this level and if it attempts to do so will cause damage. You want to find the maximum continuous wattage rating of the power supply. This is the highest amount that the unit can supply continuously to the components. Even with this, you want to make sure the maximum wattage rating is higher than you intend to use.
Another thing to be aware of with the wattage output has to do with how it is calculated. There are three primary voltage rails inside of the power supply: +3.3V, +5V and +12V. Each of these supplies power to the various components of the computer system. It is the combined total power output of all these lines that make up the total power output of the power supply. The formula used to do this is:
- Wattage = Voltage multiplied by Amperage
So, if you look at a power supply label and it shows that the +12V line supplies 18A of power, that voltage rail can supply a maximum of 216W of power. This may be only a small fraction of say the 450W the power supply is rated at. The maximum output of the +5V and +3.3V rails would then be calculated and added to the overall wattage rating. +12V Rail
The most important voltage rail in a power supply is the +12V rail. This voltage rail supplies power to the most demanding components including the processor, drives, cooling fans and graphics cards. All of these items draw a lot of current and as a result you want to make sure that you purchase a unit that supplies enough power to the +12V rail.Do not be too concerned about this is it is ONLY to show why I asked about the existing PSU
if it was me, but then I do not know KDM I would stay with one of the more widely known PSU makes.
Please note - that MAY be unfair to KDM.For the opinion of an expert on these matters see this

The entry on device manager does not mean anything as it will only see the Nvidia graphics engine.
YOU say you still have the box. - Just examine it carefully. - as I have already said.
