Power Supply - is it adequate?

  Spock999 12:27 26 Jan 2010

I have a Mesh Elite E6600 PCA. Specs as follows

ASUS P5N32 SLI premium motherboard
HEC-550TD-PTE 550w power supply
NVidia 7950 GT +256 Mb Video card
Soundblaster X-Fi Xtreme sound card
2 x 320Gb Seagate Barracuda SATA hard disks
2 optical drives

I am considering adding a third hard drive and a question has been raised about the adequacy of the power supply.

Putting the system parameters in a PSU calculator gives a recommended minimum of around 270W. Using a PSU + 12v loading calculator gives a 12V loading of 12.9A up to 13.4A with the third drive. I am not certain I have dealt with the fans adequately in the calculator.

Please advise.

You dont actually tell us the CPU, however, as long as your not experiencing problems then the 550watt PSU should be adequate.

Fans use next to no power (3W each would be a lot).

Sorry. Its an Intel E6600 core duo.

I agree with madboy33©®, it should be enough.

I might consider upgrading only if I was adding another 7950GT graphics card for example. Some GPUs can draw a lot of power.

Btw, the HEC-550TD-PTE PSU is made by Arctic Power - see Davey's post in this thread click here. They aren't the best PSU manufacturer, but apparently that the system in question was running 2x 8800GTs on the same PSU, which is no mean feat. G
