what GPU can I get with this PSU ?

[Kiddo san]

Hi guys here`s the PC, just won`t die on me:
Intel Core 2 Quad Q6600 stock @2.4GHz
3gb ddr2 667MHz
Gigabyte GA-P31-DS3L rev 1.x
geforce 8600gt gigabyte silent pipe 2 256mb gddr3

My question for you is, can I get a HD 7770 /HD 7750 /gtx 750Ti /gtx 750 with this 420W(no pun intended) PSU ? I understand that it can handle HD7750, but what about the rest

+12V(15A) +5V(30A) +3.3V(20A) -12V(0.8A) +5vsb(2A) 420W cheap PSU

Problem is that this isn't really a 420W PSU in the modern sense. That's a 90s design, PCs power-hungry components all use the +12V rail for the last 15 years. For all intents and purposes, this is a 180W PSU. Given that this is almost certainly not a quality PSU anyway and probably a decade old to boot, there's no chance I'd be making any changes, your current GPU is likely stressing your PSU to the edge already.

Figured as much. The PC itself is a decade old and ain't nobody buying *that* PSU new. I would not make any GPU change without a new PSU.
