I'm putting together a X2 3800+, a Gigabyte M55Plus-S3G, 2gb ram, 1 IDE & 1 sata2 drive, a souncard (with front panel). I don't intent on overclocking or gaming. Stability is the issue.
What is the minimum i should go for with a PSU?
i have a Tagan 330w PSU already. Should i use it?
If that PSU is ok for now, then:
In the future i will add a couple more sata2 Hdds.
I will be using the onboard VGA for now. If i have to use a separate Graphics card it will be a 6200 with silent cooling.
Will it still be enough?
The Tagan 330 can provide 18 amps on the single 12v rail, or 216w.
I estimate your max power consumtion on the 12v rail will be as follows:
Athlon X2 3800+...............................60w
CPU power consumption chart.
GeForce 6600...................................28w
(Click here for power consumption. - The 6200 isn't listed.
4 350GB Hard Drives.........................88w (22w x 4; Hard drives also draws additional power from the 5v rails.)
RAM..................................................0w (Power is drawn from 3.3v rail)
Motherboard.......................................0w (Power is drawn from 3.3v/5v rails)
PCI Sound Card..................................0w (Power is drawn from 3.3v/5v rails)
DVD Drive.........................................14w
3 120mm Case Fans...........................15w
Total max power consumption.............205w (On the 12v rail - 100% load)
The 205w estimate assumes every single component is running at their max which is unlikely to happen.
It also takes into consideration 4 large hard drives, and a faster Geforce 6600 video card. Assuming the CPU is being maxed out and you are reading/writing on two drives, I estimate the power consumption will be 175w.
Your Tagan 330 should be fine, even with two more SATA Hard Drives.
Thank you so much, you've been VERY helpful!
The cpu will be Athlon 64 3500+ (AM2) which is 48w instead.
What this setup will be used for is mainly audio applications. So, i have to take into consideration that the CPU and 2 Hdd's (1 IDE WD 320gb and 1 Sata2 WD 320Gb 16mb) will get to be at full load at some point. From what you say, this PSU is more than enough for that. Eventually i will add 1 or 2 more Sata2 HDD's. Even if i do, with all 4 at full load (based on your estimation) the PSU will be fine
Now, your post made me think:
Ocassionaly, I DO enjoy games and since you added the 6600 it makes me wonder if i could add something like a 7600gs or gt... :?: (No overclocking, default settings).
In that scenario, only the CPU, 7600gs (or gt) and one HDD (the IDE) can be put to full load.
Will i be safe? Should i do it?
