I have a Dell Optiplex GX620 Small Form Factory.
I have a hd4350 running on it and it is perfect.
But i want to have a dx11 card,,for some reasons.
1.I CANT UPGRADE MY PSU)
2.I CANT UPDATE MY WHOLE SYSTEM ,,I AM ONLY 15 years old,,,dont have so much money
The problem is that my PCI-E is only 25W max power and not 75W. (WHAT IS THIS ,,,A PCI-E SHOULD HAVE 75W)
In wikipedia is said :
"PCI Express cards are allowed a maximum power consumption of 25 W (×1: 10 W for power-up). Low profile cards are limited to 10 W (×16 to 25 W). PCI Express Graphics 1.0 (PEG) cards may increase power (from slot) TO 75 AFTER CONFIGURATION (3.3 V/3 A + 12 V/5.5 A). Optional connectors add 75 W (6-pin) and/or 150 W (8-pin) power for up to 525 W total (75 W + 3×150 W)"
So 75W. I CANT UNDERSTAND THIS.
I want a hd5570 (about 43W) or a gt430 (about 39W) but i am not sure.
any non 6 pin pci-e connector should work just fine as long as the psu is around 300watts. So with a low profile case u could get high end a 6670 or 7750. So if the gpu does not have a connector going to the power supply then it should power on just fine
