Silverstone PSU replacement for Dell XPS 420

Silverstone Tek Strider Series ATX12V/EPS12V 550W 80+ Gold PFC Power Supply with Full Modular Cables ST55F-G is for sale at $110 on Amazon. Would this be a good PSU for my Dell XPS 420 (Q6600 3.0 GHz) and GTX 670? I have a complement of SSD, HDD, DVD and BD drives, and the new PSU would be replacing the 5-yr old 450 W OEM PSU. I notice that all new PSU's have an off rocker switch, but my existing PSU/case does not. Will this be a problem for installation?

  3. The Evga has more power than what I need, and it's been reviewed as noisy. The Rosewill 550 looks pretty good for a great price, but has a ball bearing fan that isn't the quietest. I won't be going SLI in this computer because it only has one graphics port. The Silverstone is rated for 18 dBa, and there's a mail in rebate that makes the final price $95.

    I'm also looking at a Corsair CX600M 600 W Bronze that gets great reviews for $77. Its sleeved bearing is noted for being quiet, and the fan doesn't spin up until over 50% power. I also like its semi-modular design. One drawback is its peak power is rated for 30 C, while the standard is 50 C. Silverstone's is at 40 C. Both are rated highly. So is spending the extra $20 worth getting a whisper-quiet, energy efficient Silverstone? Anyone have experience with this brand?

  4. I picked the Rosewill PSU because it had all the features I was looking for and runs constant up to 50 C, and with the discount, was a great deal. It's 30 mm longer than the OEM PSU, but I measured so it should fit. Thanks for the advice!
  5. It's made by Super Flower , it's a top notch unit.
