hi guys
ive seen a GTX275 for just £38 and im considering buying it for my spare gaming pc .. however the pc,s power supply is a "OCZ 500w stealthstream psu " and this has 2 x +12v rails with 18A on each rail
now ive checked it using the popular "eXtreme Power Supply Calculator Lite"( http://extreme.outervision.com/psucalculatorlite.jsp ) and it reports a recommended 386w and a minimum 336w ,and it does state the +12v rails are also a important factor,however 36A is within NVidia,s requirement
my only concern is the wattage .... NVidia recommend a 550w but most of the time these are way above whats really needed ( it just covers their backs by overstating the wattage )
so would my OCZ 500w stealthstream psu be enough to power the GTX275( 896mb) .... I also have a C.I.T 650w psu with 19A and 20A respectively on the +12v rails so how would that be with the GTX275
finally ive also seen a GTX280(1gb) for £50 ... would either of the two psu,s ive mentioned be good enough for the GTX280 ( NVidia also recommend 550w ) ....
note : both the psu,s have just 1 x 6pin pci-e connector,however I could use a adapter with the 6pin(to convert it to 8pin) then 2 x molex to create the 6pin thus giving me the require 1 x 8pin and 1 x 6pin pci-e connectors
theres a few other cards ive seen so I will list these and let me know if any will work with the ocz 500w psu or the cit 650w psu
1) HD4870
2) HD4890
3) GTX260
as ive mentioned I can create the required 6pin/8pin connectors using adapters ... so would any of these be ok
any help will be much appreciated ..
cheers guys
