Will this ANTEC 550W work for me?

Last response: in Components

I bought an ANTEC BP 550W and I'm wondering if it will be enough to power my new setup. I'm actually afraid to turn it on. All the calculators I've used say 550W -600W, while http://www.extreme.outervision.com/psucalculatorlite.js... says I only need 482W min and 532W max, and that is with 100% System load/100% CPU usage. My fiance tossed the box when I was at work, so returning the 550W isn't an option. :heink:  This rig will be used a lot for gaming. In the calculator I didn't add in capacitor aging as well. I probably won't use the PSU for more than one year.

On a side note, will a 590GTX really out perform two 570's in SLI?

Specs:

* Asus P8Z68-V PRO GEN3
* Intel quad-core Core i5 processor i5-2500K - 3.30GHz/LGA 1155/6MB three cache / 95W
* EVGA SuperClocked GeForce GTX 570 (Fermi) 1280MB 320-bit GDDR5 PCI Express 2.0 x16 HDCP
* Kingston HYPERX x2 4G DDR3 1600
* Intel 128G SSD
* Samsung 500G HDD (7200 RPM)
* Razer Naga
* Asus 515 Chassis (has a rear fan in it as well)
* Cheap Asus DVD/R
* Massive Coolmaster CPU cooler (looks like the Hyper TX3 RR-910-HTX3-G1)
* Two big 140MM coolmaster LED fans (I want to add a third)

The ANTEC BP 550W should be enough for your system. Just turn it on!

There are several threads here at Tom´s about 590GTX vs 2x 570's in SLI. Opinions vary a lot. Anyway a single 590GTX or 2x 570's in SLI will need a more powerful PSU.

My worry is that I'll set it all up, and once SWTOR releases I'll crank the graphics to ultra and have it go boom (or sizzle) and have to spend a day fixing it instead of gaming. -.- I won't plan on SLI'ing for another year at least, so no worries on that. I have enough money for a new PSU (roughly $150 USD) but not enough for a new system if stuff gets wrecked.

I would say you should be fine. Just do not run sli off it or push in some overclocking. As far as stock, everything should be fine for the year.

GPU is factory overclocked, and I'd love to add a third LED fan and use turbo boost on my i5... :o  I think I'd like to get a 650W for safety's sake, or go bigger for SLI down the road. Guessing 850W would do it? I'll be slightly OCing down the road.

Yes 850 with a good 12V rail will do just fine. But at the moment, you shouldn't worry with the specs you have, just don't overclock too much for now :p . Extra fan shouldn't be worried about, and using turbo will keep the power level about the same, so that should be fine to use.
