Q: I was reading your review on the Aopen XC Cube EX915 and I was considering building a computer using that motherboard and case with two Western Digital Raptor 74GB 10,000RPM SATA Hard Drive on raid 0(no floppy). Lite-On 16X DVD Dual Drive, an Asus nVidia 6800 256mb, Intel LGA775 Pentium 4 550 3.4 GHz, Corsair Value Select Dual Channel Kit 184 Pin 1G(512MBx2) DDR PC-3200, etc., but i can't find any information that tells me if the power supply can handle that extra hard drive or if i should use just one and have a floppy? any help would be great.

A: To be honest, I have my doubts that any SFF PC power supply could handle that kind of load stably, but I think you'd find the problem lies in the video card more than the extra Raptor. We've had some problems benchmarking SFF PCs in the past (though not with the XCube), because their power supplies were not up to the challenge of running high-end videocards. It used to be that only hardcore overclockers and performance enthusiasts needed a power supply over 300 watts, but for newer high-end systems, a 400-watt supply should be considered a requirement. I'd seek more information and weigh your options before you commit to a SFF case with a proprietary power supply.
