what is your question..lol.. are you telling us that u will be fine with this or are u asking if its a good idea??
post #4 of 18
wattage should be ok... but pushing it.. no room for much future wiggle room

what cpu???


the gpu alone recommends a 500watt minimum psu

that obviously is to accommodate the rest of the system but id go bigger.. it should run it, but it is going to run it hot

no.. it clearly states minimum..

and I agree with u.. it will run.. but it is going to at times run it very hard

we also don't know what cpu he is running, and each hdd takes 15 watts. (avg).

all im saying is its pushing it..lol

No they are talking about peak rated PSU´s when they say minimum in other words they are talking about crappy PSU´s

A 7850 can be powered on a system with a 350 watts PSU

500 watts is way overkill for one 7850 you can do crossfire 7850 on a 500 watts

It will run perfectly fine, 430W is easily enough.

The reason the manufacturer recommends 500W is to accommodate for very poor units that can't output their rated wattage. Like the generic $20 ones you can buy on eBay.

I agree with the poor cheap psu's only giving their peak wattage, not their RMS.

the gpu he wants has a tdp of 130 watt

2 hdd"s is another 30 (avg)

1 dvd drive another 12 watt (avg)

the i5 ranges from 77-84 watt

DDR3 ram uses average 4 watts per stick

average mother board ranges from 45 - 65 watt

say another 5-10watt for fans

usb devices ???

that leaves during peak loads less that 119watts to spare.

I just if it were my own system not use the bare minimum or even close to it. he is asking for advice to build a system that im sure he wants to be safe and reliable for a long time to come. Dunno redmosquito, there ya have it I guess, two totally different answers hahahaha..

I don't want to come off as a jerk.. and respect every ones knowledge and opinion, I just think it is going to run the psu harder than it should for every day use.

TDP is not power draw something that is misunderstood all the time

TDP means 130 watts worth of heat that does not mean it will draw 130 watts those two things are not one and the same
