I bought a Sapphire R9 280x tri x OC version. I put it in my computer and it comes on, all fans work, and the lights work on the card as well. I cannot get it to bring up a display however. Ive updated my motherboard bios, but had no luck either.

My set up

i5 2500k cpu
Asus p8z68 v LE motherboard
700 watt powersupply
8 gb G Skill ram
120 gb samsung evo ssd
1 tb samsung 7200 rpm hdd

i bought this GPU to upgrade from my Radeon 6850 HD card. Any help on the matter would be greatly apreciated

Its a Rosewill RV2-700

 
Sapphire R9 280X Tri X requires 2x6+2 pin pcie power cables in order to operate and your psu only provides 1x 6pin and 1x6+2 pin. you would need and adapter (1x6pin to 1x 6+2pin) but i wouldnt recommend it as it isnt safe to try getting 150w out of a 75w capable cable. also that psu isnt that good. it is hardly a 700w unit providing of about 50A from the combined rails.! considering also that it isnt APFC. in other words i would buy a better psu for that rig with such good o/c ability!

Fair enough, i knew i might need a better psu at some point, this may be that time. Have any modular psu to recommend. and what watt? Thanks in advance

OK, the person who posted above suggested i believe an Evga 750 bronze, ill look into both of them, and its def the power supply, i used one of the molex to pci-e connectors they send with it and it worked right away. So ill be buying a new power supply monday. Thanks for your help.

i think ill get that 750 watt you suggested, it will give me room for upgrades in the future. would you suggest this power supply over a modular one?

 


EVGA B2 is a semi modular. the wired cables are the 20+4 pin for mobo and 4+4pin for cpu( (it has 2x4+4pin though) which you will use anyway.all pcie and periferal cables are modular!
