New PSU for failing one on aging system

Hey Guys,

So I've finally concluded that I needed a new PSU after my computer failed to turn on this AM until repeated on and off of the PSU. I'm not sure exactly what to get so I could use some recommendations. Currently, my system is as follows:

CPU: Core 2 Quad Q6600
GPU: Radeon HD 5670
MB: Standard Desktop
RAM: 4 sticks DDR2
HDD: 3 sata (but has 6 ports available)

According to eXtreme power supply calculator, I need 345 Watts. So I'm thinking 450 Watts PSU, at least 80+ bronze, modular(if i can get it) and less than $100 (the better value the better).

My future use of this machine would be to retool it for my wife to use as a office computer or to make a HTPC out of it.

Currently, I'm looking at Rosewill CAPSTONE-450. Thanks for the advice.

  2. Wouldn't 550W be a little much for my system?
  3. Best answer
    Your system will only draw what it needs and the SEASONIC unit is standard OEM sized which helps with the fit.
