Hi there


This is my first post and sorry if my English isn't good.alright back to the main topic,I'm thinking of doing a CFX with R9 270x with my current specs.

MOBO: MSI Z87 MPOWER

CPU: I5-4670K

RAM:G.SKILL RIPJAWS 8GB DDR3 1600RAM

PSU: CORSAIR RM850W 80+ GOLD

Case: nzxt phantom 410

Cooling case: 7x coolermaster jetflo 120mm

Current GPU: single Sapphire R9 270x Vapor-x


CPU cooler: coolermaster hyper 212x

I would like to know if it will run very well and how much watts will it consume?? Thx for helping

1) It will run well in supported games (in some cases 1.8x faster or 72FPS instead of 40FPS with a single card).

2) In some games it won't benefit.

3) In some games it makes things WORSE, especially Directx9 games. I'm fairly certain they have NOT fixed the runt frame issue which basically means that 60FPS is reported but only one card is properly doing anything so you actually get 30FPS.

So if you have a DX9 game running like Half Life 2, see how smooth it feels with Crossfire running or with it disabled. You'd probably be better to run it disabled in this case.

4) POWER:
You will have no problem. You can use an online Powercalculator if you want though. I'll post something below

Update on power: They just recommend a 700W Power Supply for 2xR9-270X.

I always recommend more than the Minimum so you're pretty close to what I'd recommend.

You can also tell by the number of PCIe connectors to the cards. If you have enough for both cards you're also fine usually.
