I'm looking at these HP desktops (for a relative): HPE-410t, HPE-450t, and p6680t. They are all basically the same. Unfortunately, they all have 300 watt PSUs, which I think is too low. A few of the reviews of the HPE-450t claim the PSU died on them after a short time. Here is what my relative wants in the computer (We're mainly interested in the HPE-410t): Windows 7 Home Premium Intel i5 760 quad core processor 6 or 8 GB DDR3 RAM 1 TB 7200rpm SATA hard drive 500 GB 7200rpm SATA hard drive LightScribe 16X max. DVD+/-R/RW SuperMulti drive 16x max. DVD ROM drive ATI Radeon HD 5450 512 MB or 512MB NVIDIA GeForce 315 graphics card Wireless-N LAN card integrated ethernet port 15-in-1 memory card reader, 2 front USB 2.0 ports, 1394 4 rear USB 2.0 ports Integrated sound I'm not sure if it matters but an All-in-one printer/scanner/copier will be connected to it. A USB backup hard drive may also be used every once in a while. Will a 300 watt PSU support all of this? The idea here is to buy a computer (for less than $950) that will still be powerful enough 10 years from now without having to upgrade. That's what I did when I bought my computer about 10 years ago. I only need to add a minimum of 512 RAM to my computer for it to work well enough to meet my needs now and I really don't even need that.
