    I needed a power supply for my Dell Optiplex small form factor. It was easy to fine on the website, it was in stock and they shipped it right out. Works perfectly. I couldnt be happier.

    Ordered a power supply to repair a dell PC from another site. The power supply they sent out was the incorrect one. After requesting an exchange, I was told they didn't have them in stock. So after a bit of hunting, I found the above refurbished power supply from Discount Electronics. Have to say, purchasing was easy, checkout was easy and the power supply arrived promptly and in fine condition. I installed it today and it worked like a charm! Next time I buy PC parts, I'm coming here first!
