like vamod said, it probably will hold up, but in my opinion i would be looking into getting a new psu. remember, the cheap power supplies with flashy lights and go faster stripes and with billion watt ratings, are ****!
The psu is from my computer that was pre-built.
I only change the motherboard and add 3 casefans and lights. I have 2 dvd-writers now, and a floppy disk reader, and a memory card reader in it, what if I get rid o 1 dvd writer and the floppy disk reader and the memory card reader. And replace it with the lights and casefans. Because now everthing is stable.
