I need to install vga 3, but I think my power supply is not good.
after connecting 4 pins for pcie remain available to only those that are seen in the attached photos, go well? your vga which are seen, are powered properly, or too much?
This is the power supply specification, can instal 3 vga with this power supply??

Thanks a lot for help
Problem with power supply
I'm not sure wheather I understood Your question exactly =) but I'll try to answer:
can You conect three cards? it depends what are those cards & what is the rest of Your system. Let's assume, Your system system eats (2xCPUs + mobo) up ~ 200-250W, so from Your PSU left ~600W at most 650W. Look to TDP's of You cards combine. If You fit to this You'll probably able to run.
But how if You don't have enough conectors? well two Molex (4pin conectors) could be merget with Y type wire (usually included with GPU) or 2x SATA to 6PIN.
so there is a way, but keep an eye to power usage. Without knowing every single detail of Your rig it's hard to tell if it will work for sure or will it be very stable =)

take a look here =) http://extreme.outervision.com/PSUEngine
from your list of parts I'd say You should be able to run if You can hook all the wires. However it's important to note that efficiency of PSU is not the same wheather You run 110V or 220-240V from wall.. In the if PSU is old it could loose a bit of efficiency.. - all in all, I'd try to run the system keeping an eye on it - You'll probably never run full load..probably use just CPU or just GPU under load, & maybe not all, cos I guess You powering the screen from one. So simply take a look, do some calculation whether You can hook all the parts with those Y wires =) if so, simply try to run. If stability becomes an issue, I'd look to PSU at first. Good thing would be to read a bit 'bout Your PSU - there are different companies that write diff numbers, some of them are acure & some of them ar not. so before putting PSU at the edged I would read a bit what other say about those =)

if i do not attach the third vga at power supply what happen?
If i add a new power supply only for thr third vga? this is ok?

probably nothing, it will not run & that's all. However If You're not using it, probably better leave it in a box rather then partially hooked in PC =) just for sake of avoiding any issues.Daniel79 wrote:if i do not attach the third vga at power supply what happen?
If You do that way You need to power it together with Your main power suply - for that use a paperclip or bridge.Daniel79 wrote:If i add a new power supply only for thr third vga? this is ok?
