If you’ve built a few PCs, or repaired a few PCs, you have some idea how important the power supply is. If you buy any old tin box that fits, you can probably expect to run into some problems. Here’s some advice on buying power supplies, including reliable power supply brands.
Earlier this week, when doing an emergency computer upgrade, Firefox gave me a weird problem. I installed Firefox, then when I tried to launch it, I got the popup dialog box stating that Firefox is already running. When, of course, it wasn’t–I’d just installed it.
I found a cross-reference for power supply brands and OEM manufacturers. It’s a couple of years old, but still useful.
Way back when, I knew that Sparkle Power actually made PC Power & Cooling Silencer power supplies. Since Sparkle units were cheaper, I bought those, and got good, reliable power from them for years until they were obsolete. That information is obsolete now too; Sparkle was bought out by FSP many years ago.
This chart tells you a whole lot more than that. And it validates that my current practice of buying Seasonic power supplies whenever possible is probably good, since Seasonic is the actual maker for several premium brands of power supplies today.
In the early 1990s, I learned how to fix computers because I got tired of long waits and shoddy repairs from computer stores.
Last month I took a friend to go buy a computer. I didn’t want her to get stuck with retail junk, so I took her to a computer store that I knew sold quality parts. Plus I know the owner. He wrote an O’Reilly book too. I figured it would be a smooth experience, since I knew exactly what to ask for. The salesperson said he’d get back to me within two days with a quote, then it would take about a week to build the system after we gave the OK. Seems pretty smooth and reasonable.
It turned into a nightmare. Or at least a mess. Read more
I’m fixing up my mother in law’s Compaq Presario S5140WM. She bought it about five years ago, a few weeks after her daughter and I started dating. It’s been a pretty good computer for her, but lately it’s been showing signs it might be overheating.
I took the shotgun approach, replacing pretty much everything that I would expect to be at or near the end of its life at five years.Since we seemed to have a heat problem, I picked up a better copper heatsink/fan for the CPU. The copper heatsink promised to lower the temperature by 5-10 degrees on its own. Since I rarely get more than 3-4 years out of a CPU fan, this was pretty much a no-brainer.
I also picked up a Seasonic 300W 80-plus power supply. I doubt the machine will put enough load on the power supply to actually get it to run at peak efficiency, but I also figured an 80-plus power supply would probably be better built and more reliable than a more traditional power supply. Seasonic is hardly a no-name, acting as an OEM for a number of big names, including Antec and PC Power & Cooling.
Finally, of course I replaced the hard drive. Being a parallel ATA model, I was limited in choices. I bought a Seagate rather than a Western Digital, because I’ve had better luck with Seagate through the years, and Seagate has also absorbed Quantum through its purchase of Maxtor. Maxtor admittedly had a couple of rough periods, so say what you will about Maxtor, but every Quantum drive I ever bought still works. I have a Quantum drive I bought back in 2000 still working in my computer downstairs. Yeah, it’s slow and loud, but it’s been ticking away like a Swiss watch for 8 years, in almost constant use! Maybe some of those Quantum engineers worked on this Seagate. To Seagate’s advantage, they do offer a 5-year warranty on their drives, which is really good, considering the conventional wisdom on hard drives used to be that you should replace them every three years because they’d fail soon afterward. Unless the drive was a Quantum, that is.
The question is whether I just clone the old drive onto the new drive, or install Windows fresh on it. I know if I do a fresh installation, the thing will run like a cheetah, free of all the useless crud HP installed at the factory. The question is how lazy I am.
After buying a new hard drive, power supply and CPU fan, I’ve sunk nearly $120 into this old computer. But it’s an Athlon, faster than 2 GHz, so it can hold its own with a low-end computer of today. The onboard video is terrible, but I solved that with a plug-in AGP card. It has 768 MB of RAM in it and tops out at a gig, but since she mainly just uses it for web browsing, 768 megs ought to be enough. I’ll keep my eye out for a 512MB PC3200 DIMM to swap in just in case.
And besides all that, since this Compaq has a standard micro ATX case, if 1 GB starts to feel too cramped, I can swap in a new motherboard/CPU that can take however much memory I want. And the power supply is already ready for it.
But as-is, I think this computer has at least another three years in it.
