I'm looking at upgrading my rig, so i need a new psu. My current psu is at 300w
12v1 10A 12v2 12A
3.3v 20A 5vSb 2A
5v 16A -12v 0.5a
Now the power supply that i'm looking at is :COOLER MASTER eXtreme Power Plus RS500-PCARD3-US 500W ATX12V v2.3 Power Supply it's a 500w psu
+3.3V@22A, +5V@25A, +12V1@18A, +12V2@18A, -12V@0.5A, +5Vsb@2.5A
They all match up but the rails numbers are different. Ex:12v1 10A = 12v1 18A
Would this be a problem or purchasing it would be alright ?
Edit: I've heard that this series of PSU is bad, so i found another one
RAIDMAX RX-500AF Continuous 500 watts ATX 12V v2.3/EPS 12V SLI Ready CrossFire Ready 80 PLUS BRONZE Certified Power Supply
No, a 6850 needs more power than the pci-e slot can deliver. Namely a 75w 6 pin pci-e power connector.
Using molex to 6 pin adapters will not do the job.
The strongest card you can use without a psu upgrade would be a 7750.
I know that, That's why i was considering upgrading from this OEM PSU (Forgot to mention)
But will an "Antec NEO ECO 520C 520W Continuous Power ATX12V v2.3 / EPS12V 80 PLUS Certified Active PFC Power Supply " Do the job as k1114 suggested ?
