Digital Cameras Photo Reviews of Diablotek DA Series 400-Watt ATX Power Supply PSDA400Customer Review: Very Inexpensive 400W ATX Power Supply for Dell Dimension Summary: 5 Stars
09/26/10 Because of the multiple fans drawing air into the case, more dust was accumulating at the case' front air intake (bottom of front bezel) and small rectangular hole at the bottom rear. Three months ago, I made minor modifications to the mid-tower case by cutting measured pieces of polyurethane foam a/c filter material ($1 at Walmart) and using cut-up Velcro squares at the corners to hold them in place (popped off the case' front bezel, attached filter foam, replaced front bezel). The foam filter was large enough to cover even the front 3-1/2" and 5-1/4" drive bays. Today, MUCH less dust inside the case/on the components, especially the video adapter with its own fan. The power supply continues to function flawlessly six months later.
I purchased this power supply to replace the original 230W unit in our Dimension 4600 in preparation for installing a high performance video adapter replacement to drive a 24" flat panel monitor. The desktop already has 2 Ultra ATA hard drives (original 80 GB and 400 GB) and 2 SATA devices (1TB hard drive and dual-layer DVD burner) and the original PS was not going to be enough -- the monitor would blank out for two or three seconds during moderate graphics rendering at below 1080p resolution. The old power PS came out in a few minutes. After unplugging the power and data cables from the devices, I used a vacuum nozzle following/behind a paint brush to remove the dust inside the case, on the devices and components of the MoBo. I also removed and cleaned the case fan and air duct that draws air from the CPU-heatsink and blows it out the back of the PC's case. I used a smaller paint brush to get to the dust that coated the aluminum heat sink. When satisfied that I got all the dust I could remove, the new PS was installed and it fit perfectly. The dual fan design of the new PS is very good -- one underneath to draw air from the case interior into the PS, the other in the standard rear location to draw air from the PS case out the back of the PC's case. Single fan designs don't flow as much air, and the dual fans work together so there is less electrical load on the fan motors. I had the PC up and running within half an hour of removing the old PS. The true test came when I removed the old video adapter and replaced it with an AGP 8x ATI Radeon video adapter that needed a power supply connection for the adapter-mounted fan that draws air over the card's processor and out the back of the PC's case (that makes four (4) fans that draw air out of the PC's case, so dust will accumulate at and around the front of the PC's case where the air is drawn in -- I can feel the draft with the back of my hand). No more blanking out of the monitor at full 1080p resolution running high graphics rendering tasks. The system's been running without a hitch for over a month and a half. So happy with the <$19 + free shipping that I ordered another identical PS for another Dimension used as a file server. Highly recommend this PS as a higher wattage replacement.
