So this time wy didn't Anandtech mention how fast those PSUs were or how they "interfered" with memory contents, as was done in their 2003 review?

Re: Hitachi 5K3000 2TB experiences
I got 10 slow sectors with MHDD's surface scan, compared to 2-3 with my 2TB Samsung HD204UI and 0 with my 2TB WD20EARS and 1TB Hitachi 7K1000.C drives. Zeroing out the drive didn't change anything. Also the exact LBAs of the slow sectors change slightly on each test run, by more than just a few numb...

Re: SpinPoint EcoGreen F4EG 2TB HD204UI/Z4
I have a 2T, F4 data drive in my WHS. I installed and ran the tool (made by Acronis). It reports the drive as Not a Samsung Advanced Format Disk , and a greyed out icon for the drive indicates Optimally aligned partition. Same here, and I used Windows XP to partition and verified the misalignment.

I have not yet found a mainboard that did not work 100% reliable with Kingston ValueRAM. Kingston 256MB ValueRAM PC2100 would not work at stock settings with ECS P4S5A2 (SiS 645 chipset) but worked fine with ECS K7S5A Pro (SiS 735 chipset). Then there was my experience with 12-13 Kingson ValueRAM 5...

Don't attach anything to the heatsink with the high voltage transistors attached to it because: 1. If the thin insulation on any of those transistor fails, the heatsink will have high voltage riding on it. 2. Some PSUs are designed so that heatsink is connected to high voltage, and I believe it's fo...

I tried 350W and 400W V-Series PSUs, and while I can't comment about the power output, I found this about the build quality: With one 350W, the fan failed to start when the PSU was turned on in about 2 out of 20 tries, but the second sample, apparently from a different production run (yellow capacit...

The words "Noise Killer" have to be on the PSU itself because Fortron-Source has sold PSUs where "Noise Killer" was printed only on the retail box, and there was no fan controller inside the PSU itself and the fan ran at full speed all the time. AFAIK, the fan controller of any 80mm Fortron-Source P...

i just thought from reading the sticky (thread about Low power system not booting with high efficiency PSU?!) that cold booting would be an issue, and that i would need to find a psu that did not need a min of 1A load to boot up.

Also the PSU bottom will only have contact with wood or soft foam so the case won't help any with grounding as it does in a "normal" metal case. Isn't that soft foam really flammable? One person had a HD burn in an external enclosure burn one of its chips, and in turn it burned a hole in the plasti...

Here's a 250W reference design from On Semi that's at least 80% efficient:
http://www.onsemi.com/PowerSolutions/content.do?id=1331
The documentation is 35 pages, and near the end it warns that the design has a few bugs.

The only review I could find is this one: http://terasan.info/dengen/no069/index.html I wouldn't worry about the heatsinks being puny because 120mm fans work so much better that they're OK -- even Fortron and Seasonic 120mm PSUs are like this. I haven't experienced any loud Delta PSU fans, but their...
