Corsair CX430 going to be ok?

[Jim Bancroft]

I have a Corsair CX430 PSU and want to upgrade my system's guts. Nothing too intensive planned, but thinking of a Radeon R7 260, and an AMD quad core FM2 chip.

An SSD boot drive, a 2 TB WD or Seagate second drive, a DVD burner to round things out. Will have four 120mm fans running in the case.

This PSU does 32a on the 12v rail. No overclocking planned. Am I in this PSU's comfort zone? If I ever tried SLI would it be too much to ask?

Yes, you should be OK with a single 260, but Crossfire/SLI would not be an option.

Appreciate it, thanks. Out of curiosity, what rough numbers (wattage, 12v) on a PSU make, say, a 2 card SLI/Crossfire setup feasible? Realizing of course that overclocking can affect things.

Depends on the video cards to be used for crossfire / SLI
In this case, I would be bold enough to say that the CX430 v2.3 (80+ bronze) is good enough for 2 R7 260 in crossfire.

Try the PSU calculator at outervision, and if you have the pro subscription it even tells you how many amps in the 12V rail you need.

Thanks for the link, very informative!

Yep a CX430 should easily be able to handle two 260s. They use less than 100W each, so with the GPUs & CPU fully loaded, you will still have more than 100W to spare.

yes, corsair cx430 is OK for that system

32x12= 384w

CX430 CAN run two R7 260's in CROSSFIRE, not SLI...

But as a general rule of thumb, PSU's that only have a single pci-e power connector, is meant for only cards that require a single pci-e power connector to power it.

If you ever need to use Molex to pci-e adapters, in this case, you would if you want a second card, it's generally recommended to get a more suitable PSU.

Below links shows total 12 volt rail needed on the PSU.

Comfort zone of 10 - 15 amps extra for another card.

depends on which revision you have. If you have Rev 2.3 it will handle it but always be "running on 10". It will last maybe a year or 2.

OP: You'll be fine. And if you want more performance, Xfiring 260s is a dumb idea. Much better to sell and trade up.
