LOL, BFG says 575W and eVGA or XFX says 650W. These guys should be locked in a room until they agree on a number.
OK, if you'd rather have more room for fans and disks and so on get a 750TX or a PC Power & Cooling 750W. They would cost about $20 more.
The GA-EP45-UD3R has 3 PCI slots (the UD3P only 2). It costs $15 less. The disadvantage is that it only has one PCI-E x16 slot. That means you lose Crossfire, but you don't care with the GTX 285 anyway. You also lose the ability to add a cheap 8400GS or similar. That could be handy if you ever want to use 3 or 4 monitors. That's about it, I think.
I want to go SLI but I dont think I'd need to for a while with the GTX 285, do you? And the card is already $400... so I cant afford 2 of them now and to get an SLI mobo, it'd cost $40-50 more pluse a bigger PSU to hold two gtx 285's.....idk.
A GTX 285 should handle a 22" monitor very well IMO, no worries. It can deliver 40fps at 1680x1050 in Crysis Warhead in DX10 with all the eye candy. You'd get even better fps in other games, I think. You can see some numbers here. They used 1600x1200, but that's very close to the 1680x1050 you'll get on a 22" widescreen. http://www.guru3d.com/article/geforce-gtx-285-review--3way-sli/17
Last actual test I saw had the GTX 295 pulling 300W at load, so I can't imagine the GTX 285 needing more
As for the UD3R, I'm not so sure aevm. I agree that the layout is nice, but I just pulled up the two newegg photos side by side and the UD3R is using different capacitors. It's a bit blurry but they look like they might be rated differently. Might effect overclocking, possibly?
My current PC is running a 400W, a 700W wont make my light bill go up will it? lol
Your light bill may actually go down a bit, if the new PSU is more efficient than the old one. Let's say you need 300W for your parts (CPU, GPU, etc.) A typical 400W PSu would do it at 75% efficiency so you pay for 400W. A good 700W PSU would do it at 80% so you pay for 375W (80% of 375 = 75% of 400 = 300).
