How to check psu for wattage, if it has no sticker?
I've found a psu "super flower" : D
It has no stickers or checkable serial number.
I also haven't found any other models looking like this one on the internet.
It has 2 8 pin connectors so i presume it can be over 600W
It would be a great piece for experimenting.

It is working, but i would like to check if it has any problems with voltage, or what power it can deliver.

Did it originally come in a computer? If so you can probably download the technical guide online and it should say what PSU's it shipped with.

It was not a branded pc, some core 2. I've been already lookin after any stickers, names or serial numbers, nothing to be of use.

When you say super flower, do you mean that it has a super flower sticker on it?

Yes, its on the psu. I looked at all psu's on the internet of this brand, but didn't find the one I have.

Older Super Flowers were poor quality , in the past few years most models are very good.
