[Tom's] Don't Be Surprised When Your Cheap PSU Blows Up

post #1 of 75

The PC power supply market is one of the most difficult for enthusiasts and the tech press to address. There are products for every requirement, every performance category, and even for most tastes in design, not to mention the huge price span! In our past power supply roundups, we tested products ranging from a little more than $40 to more than $200. With very few exceptions, most of the units we've evaluated have done what they've claimed; sometimes by a long-shot and other times just barely.
I thought this is more appropriate title for the article - they bought 3x low cost PSUs from ebay that have a total of 1670W for a grand total of 60€/$. If you're curious at what wattage each blew up click on the link below:

I'd rather go without a computer until I could afford a quality PSU, then use one of those.

You are likely to end up going into more debt after the thing fries your computer.

It's a hard argument to support to non-enthusiasts though - spending more money on reliability rather than performance is a tough position to defend (even though when people buy cars, it's often a cited argument)

This is true. Most consumers see the number on the box and believe that all PSU are the same.

I guess a good way to put it is this: A cheap PSU is like feeding yourself only fast food. Can you survive for a while? Yes Will you die sooner due to poor diet? Yes.

No news there - just another example that points in the direction of paying a little more - is cheaper in the end ..

Until some 10 years ago I had that type of PSUs. They've never failed on me because of one simple thumb rule: take the wattage rating, divide it by two and keep as much below that as possible. Then, it works - I had a 400W PSU for a Duron 750MHz w/ Geforce 2MX and the +12V still dropped ~11.8V under load Good times.

Now it would be pretty stupid to buy on of those PSUs for anything but a low cost low efficiency and low power rig.
