|It is possible that your Coolmaster 500W power supply is not up to the task of the new computer and graphics card. Coolmaster makes a few lines and the cheapest often low on the 12 Volt rail(s) which is needed more now for the newer computers and for your graphics card. You should look for power supplies that have a single 12 volt rail, 50% or more certified efficiency, active PFC, and a quality name brand. Avoid the cheapest, but there are always decent ones that are reasonably priced. Post the detailed specs from your power supply to be sure, especially the amperage on the 12 volt rails and (if supplied) the wattage on the total of your 12 volt rails (independent of your total wattage). Just to be sure, tell us if this is the same power supply from your old PC.|
This 430Watt power supply I am sure has more available 12Volt amperage available than your 500Watt unit:
Plus it is reasonable and with the rebate will only cost you about $22.
These are the detailed specs:
+3.3V@20A, +5V@20A, +12V@28A, -12V@0.8A, +5VSB@3.0A
notice that the 12 Volt can supply 28Amps and if you look at the image of the label, the 12 Volt can supply up to 336Watts out of your 430Watts total if required (and nothing else needs some of it).
You have too many fans, the MOST you need it one front input fan, one in the rear, and one in the power supply. Putting one in the top will not hurt you (not needed) but the side fan(s) can disrupt the proper air flow.
You have to be a little bit crazy to keep you from going insane.
