PSU dilemna..ugh please help

post #1 of 6
Thread Starter 
I made the mistake of choosing a cheap $30 dollar 600w psu and now it shuts off mostly at startup.. I need a new psu. Would a 700w be good for my build or is it overkill? Do I need more?? EVGA recommends a minumum 500w..

I don't want to buy one and find out its still not enough.. I've gone to sites with calculators and they all range anywhere from 500-700 watts..
ahhhhhh....help

The Build
Asus p6t mobo
intel i7 950 3.06ghz
evga geforce gtx 260 graphics card
6x 2gb ddr3 ram
3x hard drives
cd/dvd drive
3x cpu ans case fans

500W would be fine, 700W is way, way more than enough, you really don't need anywhere near that much.

Thank You Shub.
I appreciate it.

I'm curious how you figure out the watt numbers?

Honestly, just a long experience. If it's a simple setup anyone with some experience can tell you how powerful of a PSU you'd need

Asus P6T motherboard $250
Intel Core i7 950 CPU $280
6GB triple channel DDR3 kit $90

Cheapening out on the PSU, which causes problems... priceless!

LOL, give us the dirt on the PSU! C'mon! What brand/model?

You don't have to spend hundreds on the PSU, but you shouldn't use crap either.

You can sometimes figure out wattage from the manufacturers. The components in a modern gaming rig that draws the most power are the graphics card and the CPU.

GTX 260 (click on Specifications and scroll down to "Maximum Graphics Card Power (W)") 182W

Core i7 950 (look for Max TDP) 130W

Intel X58 chipset 24.1W

Everything else is a lot less power draw. Also, power draw goes up when overclocking. For instance the CPU might be hitting 150+ watts at 4GHz (varies depending on voltage you use). Hard drives typically have a spin up wattage of around 15W and operate around half that. Also, chipset wattage probably doesn't include the rest of the motherboard. Fans will have labels on them saying how many watts or amps they use (watts = amps * volts). Remember also that everything you plug into USB also draws power, up to 2.5W per port (more if it is an iPad, LOL).

500W is fine. The issue is you will want a decent unit and not a cheap unit. Now, decent doesn't mean expensive, especially if you find a good deal. Even if you don't find a good deal, you should still be able to get a suitable one in the $60-90 range. Typical recommended units in that price range are Antec Neo Eco/EarthWatts/True Power New series, Corsair VX/TX series, Rosewill Green RG series, XFX (I hear they have a 650W on sale somewhere for around $60-70), Seasonic... probably quite a few more. All depends on what is available at your favorite shop and what the sale prices are.
