Help me decide a PSU for an upgraded GPU.

[brsund06]

I am currently running an AM3 1100T 125w phenomx6 on an 880g usb3.0 biostar board with 4x4gb ddr3 1600mhz ram, 1 HD 6870 XFX, OCZ fatal1ty 550w psu, 1x 500gb hdd 7200rpm,2x Sata3 60gb corsair force gt in raid 0, thermaltake v9 case, and a EVGA superclock cooler on the cpu.

I have decided to upgrade my GPU to a Sapphire R9 280x OC toxic edition. I am looking at two power supplies that have caught my attention. It states that 750W is recommended.

( SAPPHIRE 100363-4L Radeon R9 280X 3GB 384-Bit GDDR5 PCI Express 3.0 CrossFireX Support Video Card Tri-X OC version )

Antec EA-750 PLATINUM 750W 80 PLUS PLATINUM Certified Power Supply

EVGA SuperNOVA 750 G2 220-G2-0750-XR 750W ATX12V / EPS12V SLI Ready 80 PLUS GOLD Certified Full Modular Power Supply

Ones platinum the other is gold rated. Surprisingly the platinum one is slightly less expensive.

EVGA SuperNOVA 750 G2 < Get this one it's the best 750w on the market.

Summary 😀

The gravy train keeps on rolling for EVGA today with the G2 750W. Expectations were high, and EVGA rose to them without breaking a sweat. I have to imagine that over at EVGA headquarters, they have to regularly take breaks to go up on the roof and yell, "Top o' the world, Ma!" I certainly couldn't blame them. Now all we need from EVGA is their answer to the Corsair AX1500i, and we'll be all set.

The Good:

excellent voltage regulation
less than 15mV ripple on the outputs
switchable semi-fanless mode
excellent build quality
10 year warranty
competitive price

The Bad:

nothing

The Mediocre:

10 year warranty requires registration first
