ive 2 same cards on hx650 (only cards and pciex power, mobo and others using a chieftec apc1000 and 2 more 280x) running for 2 months without problems.
600-620w drawing from wall
Topic: 2X280X on a 720w psu possible? (Read 733 times)
If the AX is pulling 500 at the wall, internally it's about 460W (before conversion losses). Buy a Kill-a-watt to measure at the wall pulls.
is possible, your system needs ~500-550w.
for example, my rig 2*asus r9 280x, celeron 1620, 8gb, 320gb, PSU corsair AX760 consumes 500w from outlet without overclocking

Yea I have 3 systems setup just like those.... dont push them because they will be right on the edge.
My pc specs:
CPU:Intel E5200 2.5ghz(Accirding to intel website it uses 65watt.As its been like 5 years I am assuming 70watt now)
Mainboard:Gigabyte G31
Ram-2GB DDR3
HDD:Samsung SATA 250GB
PSU:Corsair CX750
GPU:Sapphire 280X dual-x overclocked edition
I heard 280X uses 260watt power during mining,not sure though.Can I add another 280x on this psu considering all the other hardware's needs?
