Is it OK to replace capacitor of low esr with non-low esr in PSU?

[bshi02]

I have used hec 300ar-t as PSU for old pentium4 build but Caps in mainboard start to bulge and have experienced something wrong on any OS circumstance(xp so on..).
I disassembled hec 300ar-t and look into whole caps soldered onto PCB,but can't spot any bulged caps
But I would like to replace highest 3300 uf capcacitor in hec 300ar-t because I have a successful experience in repairing retro video game console by replacing high uf capacitor in PSU unit with other one .
I went to Yongsan Electronics Market and drop in ETLAND building, bought 16v 3300uf KMG capacitor,Although I tried to purchase high grade caps but I failed to locate any store in Yongsan Electronics Market where sells any low esr caps.
After coming home, I found that KMG series is not low esr capacitor,while native 3300uf capacitor is low esr capacitor(capxon GL) which soldered onto hec 300ar-t PSU PCB.
Would it be any possibility of disorder or breakdown hec 300ar-t PSU If I should replace low esr capacitor with non-esr capacitor?

yes, there is always a possibility that general purpose caps do not filter higher frequencies aswell as low esr caps do, better get it right the first time, so you dont waste your time:
soldering/desoldering/soldering

The GP cap might be OK to start with, but the ripple will be higher than it was originally, and the cap will have a shorter lifespan, since it isn't designed for the stresses it will encounter in the PSU.

The reason why I tried to replace low esr cap with general purpose cap is that the caps I bought is manufactured from Nichicon,I think any caps manufactured from Capxon is not high grade comparing to any cap from Nichicon albeit it claims true low esr caps.

yes, there is always a possibility that general purpose caps do not filter higher frequencies aswell as low esr caps do, better get it right the first time, so you dont waste your time:

Then Not able to filter higher frequencies as low esr caps do trigger no breakdown or do any harm at all any Computer device(mainboard,hard ,dvd drive )or any components in PSU itself, if I should replace with GP caps in PSU ?
replacing with GP caps result in only shorten lifespan of caps in PSU, not shorten caps on mainboard?

They will not filter higher frequencies ok, so the componentes in the mainboard, hard disk, etc, will suffer more stress and can be harmed. Better to search for better, low esr caps.

Caps in the PSU going bad always means more stress on the mainboard, therefore the mainboard caps will go bad as well.

Thanks all for your advice!
I finally make out higher frequencies from PSU let computer device under stress and Someday, it may result in mainboard or hard drive failure.So I decide to place an order with online store for low esr capacitor,even though It require to purchase at least twenty quantity every only one specification capacitor.
