Guys, I need some help. I have a system with 5 GPUs, and I want to add one more (R9 390) to complete the 6 slots. My whole system is:
-ASROCK H81 PRO BTC
- Intel Celeron G1820
- 8GB RAM
GPUs:
- MSI R9 390 gaming 8G
- MSI R9 290x gaming 4G
- Gigabyte R9 290 reference
- Gigabyte RX 480 8GB refence
- XFX RX 480 8GB double dissipation with 8 pin
PSU:
- Cougar GX800 (holding motherboard and all rises + R9 390 and R9 290X)
- CX 750 (holding R9 290 and both RX 480)
The question is, do I need to upgrade the PSU or are these two already able to get the job done?
*If anyone has any tips on how to redistribute energy between the PSUs. Please, feel free to talk.
Depends on your watt usage - looks like it you have enough power between both your PSU's - I'd put your Mobo and 2 GPU's on the 750W and then power the the 4 remaining GPU's with the 800. If $$ is not an issue the I'd get new Gold or better 1300W to 1600W.
