I'm considering buying an ISO 400-PP power supply for $16.50 (P&P Included). Proline rebranded these power supplies and sold them on the South African market. From the little info I could find, it seems like they used cheap parts. Worth saving or should I look elsewhere? Exterior: http://i.ebayimg. …

13007 usually blow at 250W. 470uF Yang Chun What is their real capacity? My experience with those Deer/L&C/Premier/Allied/Force psus is that the primary caps usually are fake. The pattern is like this: 470uF --> real capacity: 330uF 560uF--> real c: 470uF 680uF--> 560uF 330uF--> 220uF

El-33 --> 250W max depending on switching transistors and primary caps

Depending on the parts used that platform could do up to 400W. Take a look at this: http://www.hardwareinsights.com/wp/the-2012-e … -TM-420-PSAR-I3

This would be a great learning project. What IC is used on the Deer psu? 2005 chip of the year?

Definitely worth recapping. It won't be easy though.

I see Rubycon and Panasonic capacitors there! This is definitely a decent psu of its age...

PPFC has no negative or positive impact on PSU efficiency. APFC on the other side produces heat and lowers efficiency. I have never come across a psu with Passive PFC coil getting noticeably hot.

Not easy to tell... Seasonic is my number 1. Hipro and Lite On are very good too! Enhance is almost flawless! I like FSP but some of its designs had some issues (for example high ripple). Herolchi is 1 of my favorites, but it is not on top 5. And there are many OEMs that I just don't remember right …

Hmm, I see. Well, a trick to get away with junk caps (provided they are not already bad) is fan modding the psu fan controller so that it doesn't overheat. The psu remains fairly silent, but the fan spins a bit faster and the caps are not cooked.

GPS-400AA That's a Delta 😀 😀 😀 😀 😀 😎 😎 😎 😁 Delta is in the top 5 of best power supply manufacturers. Definitely worth recapping and keeping!

Well, it's a lot of work to do to get 250w if you are lucky.. You are right. At least don't toss it 😀

The following is 95% correct but you should check yourself just to be sure: +5vsb: 330uF 10V 220uF 16V Those can be replaced with either 2x1000uF or 2x470uF or 1x1000uF & 1x 470uF -5V: 1x220uF 16V -12V: 1x220uF 16V Those values can stay unchanged. All the 1000uF 16V should be upgraded to 2200uF The …

Don't get crazy with all this! Macron Power MPT-301 is a favorite psu among the members of the forum I posted a link before. It lacks pi coils in 2 of the 3 main outputs, but still outputs very low ripple, and its voltages are stable as a rock. There is a review of that psu in Hardware Insights, you …
