I started having start-up problems on my Dell PC about three months ago. At first, I would open up the case and reset all the component plugs to the motherboard. That worked for a while. Then I tried resetting the RAM. That also worked a time or two. Finally last week, no matter what I did, the PC wouldn't power on. The PSU would light up and the motherboard would light up but absolutely no power other than that. I did some research online and found a few other people with my PC model with the same problem. Some said they replaced the PSU and that fixed the problem. Others said they had to replace the motherboard.
I decided to try replacing the PSU first. I bought this unit (the Thermaltake 430w TR2 ATX Power Supply#. Installing it was easy; it fit my Dell computer case perfectly. Once it was installed and all hooked up, I plugged it in, pressed the power switch, and it instantly started! The fan runs quiet and I think it is doing a better job of keeping my computer case cooler. As a bonus, I now have 70w more power should I need it.
The only drawback is the short distance between component power plugs. It would be nice if they were spaced a little bit farther apart. I understand that you don't want longer cables taking up all the tight space inside a computer, but a little more distance between plugs would be nice. I was able to work around the problem though. This unit came with five SATA plugs and I only needed three, so I was able to skip a plug and use one further down the cable. I also don't have a PCIe card that needs power from the PSU. If I did, making the cable reach from a SATA component to the PCIe in the back of the computer would be very difficult if not impossible. And I have a mini-tower.
Still, all-in-all, this PSU is thus far working very well for me and I consider it to be a good deal and a high-quality product. #Did I mention that it comes with a 5-year warranty?)
