4870x2 PSU Recomendations
Okay,
I've been thinking about upgrading my 4850's to a 4870x2, and I had a question about my power supply. I currently have a PC Power & Cooling Silencer 610, and am not sure if it would be able to handle the load. I have the proper number connections, and I really doubt that a monster PSU would be necessary. What do y'all think? |

Both the PC Power and Cooling 610, and Corsair 550W will handle a 4870 X2 no problems.
They are very good PSU's.

no choose anything above 600 cos if you want to upgrade, there's more room...but a 550 can handle it...

The standard recommendation for a single 4870 x2 is at least 550W. The card at load can use over 450W by itself though, so if you have a 140W cpu, or like to overclock, I would go at least 650W. I have a 650W powering my mobo, cpu, and 4870 x2 and then a 550W powering everything else (Antec Neolink 1200W). Also make sure the PSU can push enough Amps. I called Sapphire for the specs and a stock 4870 x2 uses supposedly around 16A at idle, and 36A loaded.
Hope that helps! Last edited by Barshalen; Mar 27, 2009 at 08:52 PM. |

Most manufacturers state that the HD4870x2 requires a minimum 650W power supply. Examples of most.... XFX, Palit, HIS, Gainward, not checked any more!

Or this Corsair 850W for $129.99, free shipping, and $20 mail in rebate
 I would have got this one if it was as good a deal as it is now last month when I bought my current PSU.http://www.newegg.com/Product/Produc...82E16817139009 |

At the price of $105 before-rebate, this would probably be my choice:

Go for a PSU that has little or alot more than you need rather than 'just enough'.

Silverstone Decathlon 650:
http://www.silverstonetek.com/produc...no=da650&area= -Ample wattage, with sufficient head room -Single 12v rail -Modular -8pin PCI-E native -Jap caps -80+% efficiency And as always, you're getting Tier 1 PSU quality with Silverstone. The price is fine as well; a lot better than all the gimmick 'gamer' PSUs with their special LEDs floating around out there.

I had an Antec NeoPower 550 and it was unstable with my 4870x2. It really depends on how many peripherals you have in your rig. After I got my PC Power and Cooling 750w all my problems were solved.
