PSU selection

[jescolta]

my computer recently acted strange, random freezes , video card died and next the harddrive died, and now i have parts left the processor,motherboard and i still have 160 gb old hardrive around

a friend of mine offer 2 psu for 40 usd, both used for less than a month, ( hes paranoid that those psu would kill his system )

now i have both psu on hand and im paranoid also if these psu would kill my remaining components

1.huntkey greenpower 550 watt? (6550hg) psu
2.huntkey APFC 700 watt psu ( similar components to huntkey win7 )

which of these 2 psu would perform better or have better quality?

Re: PSU selection

Might as well get the 700W because it has Active PFC.
