upgrading my PSU please help

[badwolf2086]

I am upgrading my GPU in my Dell Inspiron 546 (mini tower). quick rundown on specs: AMD Athlon II x4 620 2.6 GHz, 8Gigs Ram, craptastic 300watt lite-on PS-5301-08 PSU. Okay not the rest. I am buying a Radeon 6850,7770,7790,6950, or 7850 (think this one more then others) now i know i need a new PSU as well, however when ever i look it up via google there is either 08HA version that i dont have or it says that the PSU is for Dell 531 or 570. I just want to find a PSU that will not hurt anything in my Computer and that will Fit can anyone Help me out? Is this actually an ATX psu or something else?

buy a psu brand like seasonic,corsair,antec,xfx,nzxt with 6 pin connectors with 500 watts these brands is excellent and a lots of safety protections,
note: it is for atx

I'll recommend the XFX Core Edition PRO550W as being a good replacement PSU that will handle your graphics upgrade

you need 2 6 pin connectors for 6950

Will it fit in the Case?. The only fan i see is rear facing but on a lot of brand PSU's i see the fans top mounted

Sorry i was talking about the fan on my current PSU is rear facing While the Fan on other(Higher quality) PSU's i have seen seem to have the fan Top mounted

the reason why fans of high quality psus are on top/bottom is because to make a good airflow from top/bottom push to the rear of case,
get the corsair cx500 it is good value for money for only $60

yeah thanks i suppose that if worst comes to worst i can try and remove the top from my case to allow extra air flow if needed

if you have a top mounted psu you are supposed to flip the psu so the fan faces down
