I just bought a new motherboard and sata drive for a new setup, i currently have 2 dvd burner drives, a dvd/cdrw combo drive, 2 ata hard dives, a sapphire radeon x1800xt 256mb pci E video card, and a standard floppy drive, does anyone think that a 550W PSU Can handle this, I need to know fast to whether not I should upgrade

The PSU:JustPC 550w
12v = 24A
5V = 40A
3.3V = 32A
-5V = 0.5A
-12V = 1.0A


I want to know if this PSU will be able to handle this setup without getting overloaded or anything like that. Someone help me fast.

I don't know much about JustPC & frankly the +12v rail looks a little weak @ 24 amps to me, but my guess is that you'll be ok.

I wanna know if ill be fine to soon move to a core 2 duo, and i will be overclocking as much as i can out of it, an aslo getting G. Skill DDR2 800 2x1 gig Ram sticks. i want to be sure im not gonna come home one day and smell smoke from my room or somethin like that.

I dont recommend the brand especially if you overclocking, I would personally recommend you dish out a little more with a power supply that wont take out components with it if it goes out.

550 watts is more than enough. I do not know if your particular PSU is of good quality, though.

 

[Atheus]

Rated wattage means little - buy based on the brand and manufacturing quality only. And the weight. Heavy is good.

My smartpower 2.0 500W psu has 2 12v rails, one rated 17, one rated 19. Do I add them together to get my total output or is that just simply 2 weak rails?
