I guess my PSU isn't enough...

post #1 of 12
Thread Starter 
So I built a new rig a few months back and I just now got around to benching it. Much to my dismay, it reboots upon frame ~1500 in the canyon flight sequence of 3DMark06 no matter what I do. Watching the Zalman fan controller that monitors PSU Watt output, it appears that when my system drains close to 460 Watts, it reboots… Additionally, looking at the SLIZONE Nvidia site, my iGreen CM 600W PSU is NOT list as a PSU that can sufficiently run dual 8800GTXs. So now I am in the market for a new PSU that isn’t going to pull major aggro from the wifie, i.e. $200-250ish.

Having looked through what now seems like a billion reviews I am stuck between two PSUs:

PC P&C Silencer 750W – Pros: Quality and $199, Cons: Not Modular and what if I upgrade?

TT Toughpower 850W – Pros: Extra Power and Modular, Cons: $240ish.

Now PC P&C argues that a single 12V Rail system is better and more efficient. Whether this is applicable to a dual GPU system like I have or not, I am not sure. Nonetheless, something that I like about PC P&C is that they have received (to my knowledge) nothing but raving reviews from everyone that has tested their products. My two issues are non-modular and is 750W going to be enough if for instance I buy a QX6800 down the line? Hmm…

TT’s Toughpower 850W has also received good reviews. I am leaning towards the TT because it has a bit more juice and is modular, which allows me to keep my case organized, enabling good air flow.

I don’t know… Any suggestions or advice that is based off experience is greatly appreciated.

No 600watt is not enough for 2 x GTX's, you need 750watt - 850watt, for the Quad Core get the 850watt

PCPC > TT by a large margin!

a good 750W should serve you just fine. Check this to see what you need:

Go with the PC&C, Its what I use for my 2x 8800GTX. Works well, no problems for me.

750W is enough for quad core and 2x 8800GTX

Getting a modular PS is a quid pro quo since you get organization but your power is less efficient or so I am told. Personally I would always go with performance over aesthetics. Both are great companies but I would go with what is better and keep in mind that you want to upgrade down the road and purchase accordingly. There is also the option of buying the 750 watt for the cheaper price and if you need the upgrade down the road you can sell the PS through this site to help fund your new power needs. Good luck with your purchase .

I think I am going with Murlocke's suggestion and get the PC P&C Silencer. Your case looks exceptionally clean, btw. Obviously the Silencer's cables are long enough to enable routing that facilitates good air flow. Thanks for all of your responses. I am anxious to see how far my rig OCs with the new power. I'll post a new 3DMark06 bench when I am finished.

Here is the best bench I was able to achieve with the gimp 600W: 13925

or

http://www.newegg.com/Product/Produc...82E16817341008

or

145 after rebate:

but if your thinkinga bout paying for the thermaltake psu

i would recommend this: its only 170 after rebate

I beg to differ. The GTX can run on a quite empty system such as one optical drive one hard drive a few fans etc with a solid 500w PSU. When in SLI the amount of watts used is not double. Considering the GTX uses around 160w at full load I would say around 250w max with both cards. On a lower system 600w with around 40 amps on the 12's would most likely be enough.

I'd go with 850 watts for 2 vid cards, 2 hard drives, and a quad core.

If you're going to add more hard drives (and you probably will sometime down the line, those raptors don't provide that much storage, so you might get a 500 GB storage drive), or if you have multiple optical drives, then definately go for 850 watts, or maybe even kilowatt.

Modular, should not be that big of a factor in your decision. It's really not THAT important, Tucking away a few unused cables isn't too tough, unless you have a mini case.

BTW, you have 765MB instead of 756MB for your vid cards in your sig (special video cards? )
