Do you know if there are any differences between HP , DELL PSUs and our market Strange PSUs ?

For normal use mostly it makes no difference but if you are using PC for heavy apps and games then you need a high quality PSU which is certified by International orgs, Tested by experts & recommended. Good Brands like HP, DEll, Cooler master and others produces good quality respecting their Brand name.

If you are not an overclocker or using high end graphic card, there is not so much difference between Dell,HP or aftermarket one, you might be paying unnecesarily for aftermarket if you're not Ocing or using stock graphic card.

For aftermarket, some are designed for higher wattage. I would browse forum to look for trustable and reliable brand. You wouldnt want a crash every few minutes which could happen with a bad PSU, or worst a fire hazard.
