Anyone can help me.I just used a PSU calculator which says that the max wattage my psu consumes is 389w and I am using a 430w PSU.Will I experience any problems if I were to continue using my CM 430W PSU?

Only 40W left, very dangerous line, as watt is only being used as guide and the calculator isn't always correct. Besides, coolermaster don't produce enough amp on 12V, better change a new one when you afford, at least 450W with high amp if you don't oc.
At the mean time, any unneccesary drive or card can be removed to save more energy. During intensive game running, opening/running many program will increase the CPU/GPU/HD usage which draw more energy, when it cross the line, the pc just shutoff/restart.

How much the calculator read when your change to X1950XT? I believe this card is power hunger, you might need a more powerful PSU.

how bout upgrading to 7900GS, any suggestion of the PSU?hopefully not too costly since 7900GS already cost a lot to me

if i'm not mistaken,X1950XT consumes lots of power than 7900GS right?

Atleast 450W for safety and future proof.
Can try get Enermax FMA II. If really budget tight then ACbel.
Dont recommend u CM Extreme Power or Real power.

I dont think there any problem as if someone on tight budget to get a cm extreme 430w for usage. I had recently help a client to build a pc running 7900gs with that psu and its rock stable with his am2 dual core, running together with 2 hdd and 1 optical drive. It aint as bad as you guys mentioned. If one can afford more, surely will recommend something which cost more.

No doubt for tight budget, CM Extreme is a nice choice.. but after some forumers die or explode their CM Extreme PSU and one of them post me the pic, now i dont recommend CM Extreme alrdy. Moreover CM = ACbel, so i rather get an ACbel.
In term of Price/Performance i would rather go for SilvStone 400w than CM Extreme.

Yes, i do agree.The Silverstone Element 400W is a very reliable PSU compared to CM extreme.But i dont think we will still be able to get the Element 400W here..Maybe the Strider 400W..

Actually pczone got...but they put it wrongly as Liberty...you go to check again pczone pricelist there...the one write there Enermax Liberty 460W / 500W, that 460W actually is FMA II 460W...they did not change it until now since few month ago after someone in this forum ask about it IIRC...

Wanna ask a question about my Liberty 400W...

As shown in above attachment, my +12V reading is only 11.19V, is it normal (from what I read untill now, it is not normal, isn't it?)?
My spec is as my sig below and 2 penaflo exhaust fan, 2 PSU's fan as intake and 1 hard disk cooler...
I have ordered my PCI-e 7600GS from forumer here...I wonder will my PSU can give enough juice to support it? futhermore, I will upgrade my ram to DDR2 667 1 or 2GB in the near future...so I afraid my PC will not be able to boot if I have that spec...

Any idea? Please give your comment...

Thanks...
