Re: PSU OCZ700MXSP no +5VSB



Luckily my order was cancelled by the shop, as I could shop there only as B2B.
I guess I can use 1.5KE200A in place of P6KE200? Latter is only available via Ali or ebay.. The 1.2KE200A is readily available.

Thanks for the tip about flame proof resistors, I assumed all of the metal oxide are.

For the light bulbs, I really need to go shopping and looking, most of the hardware stores and grocery stores carry the LED's only, unfortunatelly....

Re: PSU OCZ700MXSP no +5VSB

Momaka,

Thank you for your time and energy!



Indeed, you're right, I think I've missed that dot with my first post and stayed faithful to my typo So it's 2.2 Ohm, by size, I'd say 1W, but I'll order 2W metal oxide.

For the TNY278, as well as for the good quality and size caps, it seems impossible to source that in Europe nowdays. So if the IC is indeed toast, I'll have to wait some time before attempting to replace it.
In meanwhile, I'll get the recomended diode and resistor, test...

Ok I've found the way to use magnifier on my phone, chip is definitely TNY278PN....

Re: PSU OCZ700MXSP no +5VSB

Thanks guys, not sure how I couldn't see the your response earlier.
It's super difficult to read the chip letters, but it appears to be TNY278PN.
[I]Not sure how to test it though?[/I]
I couldn't detect short between common s pins and d or bp/m or en/uv.


As for the resistor, it didn't fail in its body, just one of the connecting wires blew, so I could read and confirm the value red red gold brown 22 ohm.
Thanks for the tip, else I would have installed common 1W resistor.

As for the diode,...

Hi Everyone!

So my PSU decided to give up on me after trying to power up my PC 4 weeks after vacation. I've heard small bang, smelled fumes and thought it has to be a cap 😊
After opening the PSU, except the bulged bulk cap (TAEPO 470uF 400V 85C A3) I haven't seen anything else rare, burn marks etc. I checked the cap and it was indeed toast. I've ordered replacement cap (TAEPO 470uF 400V 105C A3) with similar values except it was 35mm diameter in place of 30mm, so naturally it wouldn't fit in the space of the original. I did some obscure wiring, just to check whether...
