Is a 600W PSU Enough?
Recently I purchased a Diamond HD4850 512MB (NCIX.com - Buy Diamond Radeon HD 4850 625MHZ 512MB 1.98GHZ GDDR3 PCI-E Dual DVI-I HDCP HDTV Out Video Card - 4850PE3512V In Canada.) and 4GB Mushkin Ascent DDR2-800 4-4-4-12 (NCIX.com - Buy Mushkin Ascent PC2-6400 4GB 2X2GB DDR2-800 CL4-4-4-12 240PIN Dual Channel Memory Kit - 996622 In Canada.)
When I got home and finished installing everything, it worked for a few days on my 450W PSU (I know, I'm kinda pushing it with 450W), but then afterward my computer would start turning off randomly, or restarting, or even going into standby unexpectedly. I swapped out the 4850 for my old 8600GT and lo-and-behold, it worked. The fact remains quite obvious that I need a new PSU.
Now, Because I want more than just enough juice to power my 4850, I was thinking a 600W PSU may be in order, but the manual says that a 750W is minimal! The 4850 has a TDP of ~230W under load, so 750W maybe a bit of overkill. I'm sort of debating between 600W and 750W, because I may want to CF the 4850 down the road a bit.
I'd just like to get some opinions from you guys, since some of you may have had something like this happen to you at one point or another :p
Welcome to Corsair :: HX Power Supply Product Information Its more expensive, but modular if you prefer that.
Welcome to Corsair :: TX Power Supply Product Information Its cheaper non modular design and a more powerful 12v rail.
Both would be more than enough to run dual 4850s in crossfire its only a matter of choice between a modular or non-modular design.
As for new PSU Antec EA650 sorta best-buy, but I see at NCIX some good deal for Corsair TX650/750.
imho...best deal out their right now..bang for your buck..PC Power and Cooling Quad Silencer 750W...plenty for both a single or SLI / Crossfire solution!
Does Modular really matter? Like all it means is that you can plug in or unplug cables depending on whether you need them or not, right?
That PC Power and Cooling Quad SIlencer 750...Is it as much or more than the one of the Corsair's Eagle Eye suggested?
I personally use the OCZ Gamers Extreme 700W and they are pretty solid but I'd probably recommend a 750W for what your running and doing.

The PCP&C Silencer showed no signs of stress. The fan didn't even spin any faster.
Aside from my old OCZ Powerstream 600W PSU, this Silencer is proving to be the best PSU I've ever had.
Corsair Tx650, Lov'in it!:thumb:
