Hello people of the internet, I am looking at upgrading my computer, but I'm not sure on what will actually fit in my computer. I want a Radeon 7850, and I have been recommended the VTX version. To do this I need a new PSU, but I am unsure of what ones will fit in my case, and also if the Radeon 7850 will fit in my case. This is my computer: http://h20566.www2.hp.com/portal/site/hpsc/template.PAGE/public/kb/docDisplay/?javax.portlet.begCacheTok=com.vignette.cachetoken&javax.portlet.endCacheTok=com.vignette.cachetoken&javax.portlet.prp_ba847bafb2a2d782fcbb0710b053ce01=wsrp-navigationalState%3DdocId%253Demr_na-c03511113-6%257CdocLocale%253D%257CcalledBy%253D&javax.portlet.tpst=ba847bafb2a2d782fcbb0710b053ce01&sp4ts.oid=5295969&ac.admitted=1385743481510.876444892.199480143

Thanks to everyone who replies :) (My case is

Height: 36.8 cm (14.4 inches)

Width: 16.5 cm (6.4 inches)

Depth: 38.9 cm (15.3 inches)
 
The outside dimensions don't tell me enough. Could you post a picture of the inside? The default psu for that computer is 140mm long (150mm wide and 86mm high are required for a psu to qualify as atx, only the length can vary), so another psu that's only 140mm long should fit fine (though modular could complicate the fit), hard to tell ahead of time whether longer ones would.
