New PSU tomorrow...

post #1 of 12
Thread Starter 
Ordered a new PSU a while ago, should be here tomorrow. It's a Cooler Master Extreme Power Duo 650W. It comes with 2 12+ rails at 18amps each. Would this have descent enough power for future upgrading to a HD2900XT with, lets say, a core2 6320, and 4GB DDR2 800?


******EDIT******
My retail pc store guy took the liberty of grabbing me a Zumax 600W with dual 20 amp 12V+ leads, instead of the dual 18amp ones of the cooler master. The Zumax is nice and heavy, and looks and feels to be much better quality than the Cooler Master Exteme Power Duo I was looking at. I just got home, I'll be installing in a bit, then I'm gonna see if it let's me get a little more overclocking done...

Anyone have any experience (first hand or not) with the Zumax PSU's? My retail guy told me AMD uses these for testing their hardware, anyone with info to back that up? I believe him, I would just like some reading on the subject if at all possible.

It will be ok, as long as there isn't too much overclocking going on, like CPU, GPU, and RAM at the same time!

yes that should be enough as long as one of those 12v rails is dedicated to the GPU

Some websites, like NewEgg's spec, say that 750W is needed. I'll do some more digging for ya, gimme a min!

Here ya go, read this article. Looks like you'll be ok, just DONT overclock it cause it pulls 210W at full load, STOCK!

How many power connectors do the 2900's have? If they've got 2, I could hook both rails to it, no? Also, I would be overclocking, at least the CPU and graphics core...but maybe I should be looking at 2GB ram instead of 4GB? Also only 1 SATA HDD and 1 (hopefully) SATA DVD-RW, all "excess" mobo features disabled (serial ports, etc.).

It eats 200W+ It's not going to very stable if you're planning to OC both CPU and GPU

yes, it takes two PCI-E connectors. No you can't hook BOTH 12v rails to it because one rail goes directly to the MB via the 24-pin connector and having less RAM would help, 1 SATA HDD would help, also 1 SATA DVD-RW would help, although I would not trust this power supply to push your components for any length of time. You may want to consider something with ALOT more on the 12v rails. Maybe a PCP&C with a single 12v (very stable) rail, or something along those lines!
