How big of a power supply?

Post by Bories36 » Mon Dec 25, 2006 6:35 pm

Heres my predicted specs

Core 2 duo 6600
7900gt
2gb of ddr2-800 ram
320gm wester dig hard drive
some cheap $30 sound card
2 optical drives

About 3-4 various fans




I put this in the on PSU Calc and it came out at about 585 with the 15% increase.



This computer will be used for 4-5 years running 14 hours a day. Be used about 1 hour a day for very stressing gaming, and the rest for just surfing/listening to music.

I was planning on getting a NeoHe-550, but would a seosonic 430 be good enough?

Yes, or a NeoHE 430 W if you wanted that.

Are they gonna be installing a 8800 GTX?

CPU power consumption got a sanity check lately. (Witness Prescott -> Conroe massive TDP drop.) I'd expect the same to happen sooner or later for graphics card, especially those not top of the line omg fps!!1.

Hello,

Many/most power calculators result in maximums that are way too high. There is one, that somebody linked to in these forums, that is pretty decent.

You also can go by the collective experience of SPCR folks -- your machine is unlikely to draw more than 150-180watts max; and you'd be fine with any high quality 300-400watt PS...

Try my psu calculator instead. Still work-in-progress but theres no inflated numbers.

Though i can already guess that your system will be fine even on a seasonic s12 330w.

it all depends on whether you are gonna overclock and plan for future upgrade...from the specs alone, a decent 400-450 would suffice...but if i were you, i would get one with at least 500...

if you have money, thermaltake toughpower is good...
