Hi im looking at buying the Antec Earthwatts- 650watt psu
Can someone tell me if that power supply is going to be enough?
here is the parts im going to buy with it:
CPU: AMD AM3 Phenom II 945 3.0GHz x4
MotherBoard: Asus M4N98TD-EVO
Graphics Card: Gigabyte 1GB GTX460 x2 in SLI
Hard Drive: Seagate SATA 500GB
RAM: G.Skill-NT 4GB DDR3 1333MHz
Power Supply: Antec EarthWatts 650watt
Case: Antec 300
Network: EDIMAX EW-7727IN PCI Wifi card
It says that GTX460 1GB SLI on load eats up 390W and on Furmark 483W.
The stress that Furmark puts your GPU in would rarely be achieved in the real world. So i would 410W-430W would be your load consumption on load (lets say 2 hours of gaming). Add to 150W-200W for the rest of the parts, that depends on what other parts you have. That comes to something around 600W. That leaves you with very little room. Although Corsair and other good brands can deliver stable power at those high loads. But why stress out your PSU just to save a few $$.
The Antec EarthWatts 650 is a quality PSU but is not the best option for you.
If you like Antec, the Antec TruePower New 650W (by Seasonic) is a great option. It presents all you need and it's modular.
There are a lot of quality alternatives from several brands. Here you have some of them:
I'd like to recommend going to an 850w unit. I picked up the Thermaltake 850w Blackwidow modular PSU at BestBuy for $119 with $20 off (not a MIR) just the other day. Despite what newegg says, they updated the PSU to a single rail with 68amps on the +12v line. Hard to beat that price and still get a 5 year warranty.
