big-220volt or small-12/5/ volt caps?

[montanglo]

PC m.board resets guess due to faulty supply(works ok with a new though stronger supply) so which caps to replace first?(visually all look ok)
tnx

Brand/model of psu as well as brand of capacitors in it.

Pics would be helpful, may not be caps that are bad.

yup, pics would be helpful. and check the voltage on all rails to see if there's any indication of failure in psu components..

it is a regular no name supply another manifestation is if it does not work and reset than it would not put graphics on monitor at all
Vacuum cleaned it inside as well as the m.board-no help , you suspect some supply /mobo transistors or regulators ?

Still a brand of psu would be nice, as some psu's can be good just not like the motherboard.

My friend has a really nice 700W delta power supply that he runs with his EVGA board, but he can't shut it off or he has to plug in a different power supply then take it apart and put the delta back in for some reason.

Anyways, capacitors can go bad without visual signs, but we need a better description of the problem. So you will just be doing something and it suddenly resets itself?

well first noticed supply runs but mobo would not put graphics to monitor then opened both
and Vacuum cleaned now PC sometimes works until it resets ater you start a major hdd operation , and then works for a minute until another reset..
with another supply everythng ok

Well there should still be sticker somewhere on the power supply. Just take it out of the computer and look for it. Also pictures would be really helpfull.
Reason we ask you for brand/model and pictures is because the PSU might not be that bad but it just could be that the capacitors in it have gone bad. But if it's a bad power supply, new capacitors won't help it.

ok I ll have a look but it worked flawlessly for years
