OK so heres my current rig, its just under one month old:
CPU: AMD Athlon II X2 250 3.0ghz
Motherboard: ASUS M2N68-AM
G-Card: HIS ATI HD4670 1GB 128bit
RAM: 4GB Kingston DDR2-800
HDD: Seagate 500GB
CD/DVD Writer: Samsung 22x
Case: Supercase MATX Tower Case
PSU: Heyna 350W
Ok since buying the PC I've come to know the current facts:
I should have gotten an AM3 Mobo.
I should have gotten DDR3 RAM with my AM3 Mobo.
My PSU is a waste of space.
1GB on a slower card is a waste of memory space.
The onboard sound sucks on this Mobo (gets crackly)
I will not be changing the Mobo or RAM.
I am getting the follow changes done to the PC at minimal cost:
G-Card: Galaxy 9600GT OC 512MB 256bit
PSU: Corsair CX400
I have a few questions:
Will this PSU be good enough for this G-Card?
Does this case have very good air flow?
Any other feedback, comments or suggestions would be much appretiated as well.
but again the upgrade would depend on the resolution that you game...
The 9600 upgrade will be free, the only reason I'm changing is because the ATI card is having a few issues. 1000x1200ish is what I game at on an old Dell 21 Inch CRT & I'm changing the PSU as I suspect this one might be causing issues.
^ The companies give such requirements in a broader perspective so that people who dont know how to select a high quality PSU from the rest, can just buy one with just the required wattage rating...
And generally a high quality 400W PSU would be better than a low quality 500W...the main thing that matters is the amperage on the 12V, from where the power is supplied to the graphic cards...So if the PSU has the required amperage on the 12V, it can easily handle that graphics card...
Check this article...it gives the ttoal power consumption of the whole PC with that graphics card... http://www.guru3d.com/article/radeon-hd-5770-review-tes...
Keep that in mind. Our normal system power consumption is much higher than your average system.
Single GPU 5770
System in IDLE = 228 Watts
System with GPU in FULL Stress = 321 Watts
Difference (GPU load) = 93 Watt
Dual GPU 5770
System in IDLE = 249 Watts (= 21W added over single GPU)
System with GPU in FULL Stress = 423Watts
Difference (GPU load) = 174 Watt
* The card requires you to have a 500 Watt power supply unit at minimum if you use it in a high-end system. That power supply needs to have (in total accumulated) at least 40 Amps available on the +12 volts rails.
Radeon HD 5770 CrossfireX (dual GPUs)
* A second card requires you to add another 108 Watts. You need a 600+ Watt power supply unit if you use it in a high-end system. That power supply needs to have (in total accumulated) at least 55 Amps available on the +12 volts rails.
Like I said 500W is the upper limit on the safer side...they would wouldnt want to specify a low powered PSU and the reader buys a low quality low powered one...
I had given the link to show the ACTUAL power pulled by the whole PC when using that card...
Here at the forums, there was a member who ran GTX 260 SLI out of Antec EA 500...
EDIT: But again I would certainly not suggest to try that though
And can find many like that if you browse through...So the quality of the PSU matters...
