i suspect cougar is too.

Nope, Cougar is simply HEC/Compucase's retail brand

Re: the gutless, bloated, and fried power supply hall of shame

btw i did save some parts before i tossed it.
could have fixed it if i wanted to wait a month for the part to come slow boat but i have better things to do besides polishing turds.
because that is what all leadman/coming data/deer/whatever they go by this week are.shitboxes.

Re: the gutless, bloated, and fried power supply hall of shame

I don't blame you. What did you decide to keep out of it? Usually Leadman uses decent wires because they want the exterior to look good so that it will sell...

The cutout in the heatsink around the 5VSB rectifier diode is nice.

Here's a Solid Gear SDGR-750E (Leadman LP-8869E) from a friend's computer. Secondary caps are Chengx, no idea about the others. Looks like maybe a 300W to me.

Looks fairly good actually.
PWM chip for the 5V_STBY, and a decent sized main transformer.
Note that there is a to-247 device on the secondary heatsink! That is probably a fairly beefy rectifier.

Re: the gutless, bloated, and fried power supply hall of shame

It's the same thing as the Inland. Based on the model, this one is probably rated for 750W.

A Leadman with a bridge rectifier? That's news to me!

Delta Serverpower 450W EX. (CAA-450BT A). Was browsing the Web on my Ivy Bridge system when there was a loud pop from the power supply and the system shut down. I took it apart but there is no sign of damage. I think only the fuse blew. I would like to identify the problem that caused the fuse to blow. Any ideas? It has only been in use for less than two years.

Re: the gutless, bloated, and fried power supply hall of shame

PS. I don't recall any smoke coming out of the unit.

^ If you're troubleshooting, you may want to start your own thread to get more (specific) replies. This thread is mostly meant for posting pictures of crappy power supplies (which yours really isn't).

Thanks for the suggestion. I have just started a new thread.

Re: the gutless, bloated, and fried power supply hall of shame

GTR Type-R 400W. Thoughts welcome. All the caps on the secondary are Cheng brand 10V 1000uF, no pi filter coils.

Re: the gutless, bloated, and fried power supply hall of shame

250W max with ripple barely in specs is the best you could get from it.

Re: the gutless, bloated, and fried power supply hall of shame

Forgot to post the power ratings. Is it safe to use it in a 200W system? Eg. Pentium Dual Core (E5400, 45nm), integrated graphics, 2 sticks of DDR2 RAM, 1x SATA 7200rpm hard drive, 1x DVD-RW drive and a 12cm case fan?

Re: the gutless, bloated, and fried power supply hall of shame

Looks like a good candidate for some modding though!

[goodpsusearch]

Re: the gutless, bloated, and fried power supply hall of shame

It is unsafe to use it anywhere unless you put some input filtering, coils on the secondary and change the caps.

[c_hegge]

Re: the gutless, bloated, and fried power supply hall of shame

Agreed. As it stands, I wouldn't allow that within a mile of any of my PCs.

[tleu8472]

Re: the gutless, bloated, and fried power supply hall of shame

OK, so I should add pi filter coils on the secondary and change all the caps. Do I need pi filter coils of any particular specification, or can I just rip them from another power supply? Also, on the transient filter, what do I need to add? It appears to have one coil, two X caps and two Y caps in place. Thank you for your advice.

Re: the gutless, bloated, and fried power supply hall of shame

I suspect you will need to calculate the right value for the pi coils rather than just put anything in, if you want the PSU to operate correctly and stable. How you would do that though I have no idea.
