Please refer to this
thread for reference.
Anyway, a quick summary:
I'm in need of a power supply, one that guarantees delivery (SilverStone Strider ST50F)

Unfortunately, money is an
object right now. I can't afford the whole price for the ST50F but if someone can offer an installment method of payment, I'd really appreciate it.
At the moment, I have no credit card so,
palabras de honor ra jud ni. Thing is, I'm concerned with my system because when I added the 8600 GT, the BIOS lags (as in mura fluid movement ang display). But when the card is removed, everything is okay. The card works just fine on other systems. I'm worried that the PSU may be causing slow damage to the system (Mao pay budget system na, maguba unya, unsaon nalang).
If anyone can point me at the right direction, I'd really appreciate it. Thanks!
