PROS:
  o  Affordable

CONS:
  o  Had to trim a bit of the case to get it to fit, not much, but still...

Wanted an affordable supply to replace a Thermaltake 400W supply in my brother's 8 year old HP Pavilion a1623w desktop PC.  After doing some research on line, I discovered that the vast majority of power supply vendors do NOT manufacture their own supplies, but contract out the design and/or manufacture, and I suspect to the lowest bidder.  I wanted to buy from a company that makes their own, as that gives them a bit more incentive to produce a product of more substantial quality.  So after determining three potential brands, I settled on this startech unit based on its specs and price.  While the output current stated in the specs was a little bit lower than the ratings listed on the sticker on the side of the Thermaltake, I was confident that it was sufficient.  The ONLY minor issue that arose was that the outer "ear" on the AC power socket (into which the AC cord connects) just barely would not clear the opening in the back of the case, and so the power supply would not slide completely into position. I used a pair of heavy metal shears to take just an eighth of an inch of metal off the edge of the case opening, then a file to smooth off the sharp edge.  The supply then slid into place and I screwed it down, plugged in the connectors, and away we went.  Been running for over 24 hours and it appears to be rock solid.  While it's definitely not a "premium tier" power supply, for an eight year old PC, it is a great price/performance solution, and should get him by for a couple more years at least.  Thanks, startech and Amazon!!!
