Title: Corsair CX430 power supply ? Post by: Charloz24 on January 24, 2014, 03:20:33 AM Would it be enough for just 1 280x video card?
TIA Title: Re: Corsair CX430 power supply ? Post by: Wipeout2097 on January 24, 2014, 03:24:33 AM Does it even have the 2 required PCI-e connectors, an 8 pin and a 6 pin? Does it have 30A on the 12V rail?
If it doesn't and you want to use that PSU, get the Gigabyte R9-270 OC card and a PCI-e molex adapter. Decent 470+ Kh/s Title: Re: Corsair CX430 power supply ? Post by: Charloz24 on January 24, 2014, 03:48:55 AM 28a 12v
it have pci e 6 pins connector I already have the 280x... Title: Re: Corsair CX430 power supply ? Post by: crazyates on January 24, 2014, 04:22:17 AM A single 280x will require ~230-270W. A typical idle system will be ~100W. That's only about 370W while mining. That's 60W of headroom. Your CPU ramps up, HDD spins up, or you have a lot of case fans, and there goes that 60W.
IIRC, AMD recommends a 500W or higher. I believe this is because some PSUs smaller than 500W may be a dual rail, which may not have enough amps to power the card. The CX430 should have enough amps, so I think you'll be fine. Title: Re: Corsair CX430 power supply ? Post by: Charloz24 on January 24, 2014, 06:09:23 PM What is the worst case scenario? Ex: it will freeze or not work well.. or it may kill the card?

It will probably shut down. How much does your system idle? Title: Re: Corsair CX430 power supply ? Post by: Starscream on January 24, 2014, 08:30:09 PM What is the worst case scenario? Ex: it will freeze or not work well.. or it may kill the card? It should be enough for 1 card (though you might be pushing the PSU to its max depending on your settings) and worse case scenario, the PSU will shut itself down, but that's it, not harm will be done to the card.

CX430 = $40. 280x = $400. Not worth the risk if you blow something up. Title: Re: Corsair CX430 power supply ? Post by: crazyates on January 25, 2014, 04:30:50 AM 280x's get to 300w in a hurry. CX430 = $40. 280x = $400. Not worth the risk if you blow something up. 280x get to 300w? What card are you running that gets to 300w? As I said, mine started at 270w, and after undervolting, dropped down to 230w per GPU. Title: Re: Corsair CX430 power supply ?

I have a 280x undervolted to 1.049v getting 715KH/s on a I3-2100 and the whole system is only pulling 262w - and this is with an ambient of 85f. Title: Re: Corsair CX430 power supply ?

Undervolting is another matter. I did not assume the OP would be doing this. However, to recommend a card that must be undervolted to maintain a safe load on the PSU is reckless. |
