Do you have the model name and number? If it's >500W, you might not be able to do that.
it's an e-supercase series, don't know the model, or the name either. it's written there P4-480W, and the rating was like what i mention in the 1st post.
thank you for replying =)
The power supply is something you should not skimped on. A bad one could fry everything. Plus high quality ones don't degrade as fast and have a more even and steady power flow that help prevent system instability.
To be blunt, you're going to need a new PSU. Like DJR said, it could fry some components, and if you're running it anywhere close to load, it's going to go kaput a lot faster.
if only i can replace it with better one. it's a slim case, and i don't know what form factor is it either. the casing is like this one here. looks like i need to replace the psu afterall.
