HD5750 on a HP DC7700 SFF?

[orengeva]

hey guys..

I know it's a long shot but do you think it's possible to convert my ageing (e6600,240w) dc7700 sff to a gaming machine?

Thanks

You are saying that your Power supply is 240watt? OK found the answer my self http://h18000.www1.hp.com/products/quickspecs/12543_na/12543_na.HTML
Being a small form factor you will need a low profile card for it but since your PSU is only 240watts the best card I can recommend is HD5570 (beware though there have been some reports of compatibility issues with older motherboards). Another card with out issues would be HD4650.

although it's a sff rig, it has a raiser card. So I can use a regular size cards. According to the power calculator at : http://extreme.outervision.com/psucalculatorlite.jsp I can use the hd5750 (am I right ?).

No it does not! The HD5570 is very power efficient it has a little better performance than HD4670 and consumes less power than HD4650.
HD5750 would need external power from your PSU and probably needs about twice the power.

Putting a HD5750 on a 240watt PSU is pushing it.

ok... thanks.
Now, what if I add a 120w\200w pico atx psu that will power from my main psu molex\sata connector and use it just to power the card\the HDD+DVD-Rw?

Something like : http://www.mini-box.com/PW-200M-DC-DC-power-supply or http://www.mini-box.com/s.nl;jsessionid=0a0101421f43cbb855821718478d8e83db140223fb6e.e3eSc3iSaN0Le34Pa38Ta38Rchf0?it=A&id=417&sc=8&category=13

sorry to hijack your thread! I've got a dc7700sff also and was thinking of upgrading the graphics card to a HD5450. would this be ok? I have read the recommended power supply should be 400watts.

I'm thinking about the same thing as m57.
