I bought this power supply for my HP computer.  It was the same wattage and listed as a suitable substitute.  I installed it without any problem, but immediately noticed that the power supply was twice as loud as the old power supply.  I decided to live with the extra noise.  The power supply has now stopped working all together after only 7 months.  I will not buy this brand again.

    Great Product!

Works Great!! I was a little afraid it wouldn't work because it's not the same one pictured but someone from the customer service department reassured me it would. No problems. Computer turns on perfectly now.
