Why do people skimp out on PSUs? It's like buying a high-end sports car and putting cheap tires on it. In the end the whole machine gets wrecked.

Or, in this case, a high end sports car with cheap tires, cheap gas, cut seatbelts, smashed windows, no airbag, and no brakes.

Sigh, now here come all the "I used a $20 PSU and it hasn't burst into flames yet, 5 stars! derp though I have had to replace the hard drive five times and the motherboard glitches constantly" crowd.


Im with you it drives me nuts when people say oh i havet had any trouble like no one else will. Like saying you will never be in a wreck or never get sick its going to happen just when.

Or a car that has a radio and speakers that are worth more then the entire car same with rims.

Think if it this way OP if your power dies and takes out your parts you no longer have a working computer and for a 50 bucks more you probly could have a psu lasted you years and didnt kill anything.

And I bet you anything the primary switchers are STD13007s or variants, and the +12V rectifier isn't rated for more than 12A.

This is awful, one of the worst PSUs I've seen. lachen.gif


Why is it half bridge? There are four diodes there.

Not half a diode bridge, it's the name of the topology. You can ID it because there's three transformers (the extra is an isolation transformer), and two high-capacity, ~200-250V caps on the primary, and also the PWM controller is located on the secondary.

Ohh...sorry, should have thought of that. I infact did know what that meant.

But the fact that there are 4 diodes instead of a stinkin diode bridge makes it pretty hilarious.

New PSU to replace the one that came with the Pixxo case:

Just in case anyone wanted some pictures of the internals of THIS psu.

Yup, a much better, more modern design. Not high-end by any means; but it has a transient filter, adequate silicon components, decent branded capacitors, a double forward topology.... Just a solid, non-**** PSU.
