ok so right now i have an HPZ400 workstation with a proprietary power supply so buying an off the shelf power supply is not an option with out making an adapter that can allow the off the shelf PSU to work on said workstation. right now i have a 750TI along side an HP branded 475 watt 85% bronze psu and im looking to upgrade the gpu to play games like dying light and the witcher 3. my cpu is a xeon W3565 liquid cooled 16 gigs ecc ddr3 ram an ssd aznd a HDD so what gpu do you recommend the best gpu that this psu can handle is an NVIDIA Quadro 5000
