Hey guys, I'm thinking of grabbing the RAIDMAX Blackstone series RX-700AC 700W Continuous Power ATX12V V2.3 / EPS12V V2.91 80 PLUS BRONZE

http://www.newegg.ca/Product/Product.aspx?Item=N82E1681...

I don't need SLI or Crossfire as I'm only rocking 1 videocard. However, I am using 12gb 3x4gb sticks and the 1090t 6core amd3 cpu. Will this power supply suffice? It's 30$ cheaper than the one I'm grabbing currently which is:

CORSAIR CMPSU-750TX 750W ATX12V / EPS12V SLI Ready CrossFire Ready 80 PLUS Certified Active
http://www.newegg.ca/Product/Product.aspx?Item=N82E1681...

Here is my build:

CORSAIR CMPSU-750TX 750W ATX12V / EPS12V SLI Ready CrossFire Ready 80 PLUS Certified Active
ASUS DRW-24B1ST/BLK/B/AS Black SATA 24X DVD Burner - Bulk - OEM
Seagate Barracuda LP ST32000542AS 2TB 5900 RPM SATA 3.0Gb/s 3.5" Hard Drive -Bare Drive
SAMSUNG Spinpoint F3 HD103SJ 1TB 7200 RPM SATA 3.0Gb/s 3.5" Internal Hard Drive -Bare Drive
ASRock 890FX Deluxe4 AM3 AMD 890FX SATA 6Gb/s USB 3.0 ATX AMD Motherboard
ASUS ENGTX460 DirectCU/2DI/1GD5 GeForce GTX 460 (Fermi) 1GB 256-bit GDDR5 PCI Express 2.0 x16 HDCP Ready SLI
G.SKILL Ripjaws Series 12GB (3 x 4GB) 240-Pin DDR3 SDRAM DDR3 1333 (PC3 10666) Desktop Memory Model F3-10666CL9T-12GBRL

Again, I want to make sure that the cheaper power supply that does not have SLI will suffice.

Thanks!

Looking forward to hearing from you!

I'm not going to be slugging my computer in any way getting the cheaper power supply? It just seems odd that there are so little of these in the market now.

I am not a buyer for the Raidmax, for two reasons. I can't find a qualified review of that unit, and Raidmax does not have sufficient psu reputation to take the chance. It may turn out fine, or it may be the cause of flaky problems a few months down the line.

I'd rather see you with this 520W Seasonic for $60:

http://www.newegg.com/Product/Product.aspx?Item=N82E16817151094&cm_re=seasonic_power_supply-_-17-151-094-_-Product

it also has plenty of power for your rig, and as near spotless a reputation as possible.

if you plan on upgrading in the near future id stick to a bigger psu. dont cut it close so u cant really add and any new upgrades. also go for a modular psu if u can (itll save the hassle of all the extra wires/plugs u dont need.

If you want to protect against going SLI, you will want at least a 650W for 2x460s. You don't need more power than that, but you do need a quality psu regardless (Seasonic, Corsair, Antec Earthwatts or other unit specifically reviewed by a qualified reviewer).

Both are good quality PSUĀ“s and big enough for your system.

I can't see Obsidian's recommendation lol, but the other rec's are good quality psus.

You don't need more than the Seasonic 520W you posted. It's superior to the OCZ if for no other reason than it will run slightly cheaper and cooler (Bronze rating). Further, I can't find a qualified review of that specific OCZ unit, and without that OCZ is not a psu brand I would recommend. That doesn't mean it isn't fine, I just won't recommend it.

As for OCZ's "SLI rating", both psus will do fine IF the total load for whatever SLI you would use is within their range. They have identical PCIe cables, too.

i would go with obsidians link. if you cant see it its a seasonic 620w power supply and its only $3 more then the 520w seasonic power supply.
