Hello, First of all I'd like to apologize in advance if I breech any rules, regulations or procedures this forum has. I have a Dell Dimension 3000 which has just run out of warranty, giving that the power supply blew the other day leaving a puff of dust and no working Computer. I am in search for a replacement power supply unit, having looked at the old blown one it reads 250W and I've managed to locate this ebuyer.com - Cases PSUs Barebones » Power Supplies » Extra Value » Product details Very cheap I know, but will it do the job? As the Unit shown above has a higher Wattage output than the original Dell supply, would this effect the operation of the Machine? My Dell has to power simply one CD Drive and Hard Drive. That’s all. Could someone please tell me if this product is appropriate and if not recommend my course of action, I'd like to say this Machine is part of an office network so noise consideration is not relevant, it just has to run. Thanks for taking time to read my post, I look forward to any feedback.
