Could a higher wattage harm my basic comp settings?

[aminroy]

I'm about to buy a new set of intel CPU desktop. the MOST basics requirement.

But. i'm thinking to set up a higher wattage than my desktop required for future add-on (graphic card, physical drives n etc).

Will it hurt my system? long term? short term?
What's the pros & cons?
what's the rail voltage to be exact?

specifications :

1. CPU : intel i5, 2320, LGA1155 - 95W
2. RAM : Corsair, 4GB, DDR3, 1333 - ?W (little i think, should be less than 8W)
3. Mainboard : ASUS P8-B75-M-LE, B75 Chipset, onboard VGA graphic (RGB,DVI,HDMI) - ?W
4. SSD: Corsair, 60GB - < 4W
5. External storage : 2 x 2.5inch HDD - ?W (at 3.0 usb)
6. DVD/RW-ROM : regular - ?W
7. Peripherals : dual display, mouse, keyboard, wifi adaptor n etc.. - small W

empty PCIe, no physical HDD, not doing overclock,

Required power approximately = ~ 280W

setting up for, acbel - 500W + 50W.

400W should be enough already right. But.....

n BTW, can this onboard graphic support extended display (dual-display). cause they never said (asus site)

PSU i meant of course

 

[Guest]

no. your only paying for what you do not need now but in the future. a PSU will only put out the amount needed (load)
