RAIDMAX RX-1200AE 1200W ATX12V v2.3 / EPS12V SLI Certified CrossFire Ready 80 PLUS GOLD Certified Modular Active PFC Power Supply
  • Verified Owner
  • Owned For: more than 1 year

Pros: -Bought 3/15/2012 and it's still going strong
-I've run this with 3 Radeon 7950 GPUs and it didn't even get toasty.
-The rails are rated for 40Amps which means you should be able to run 4 R9 290x's, just can't overclock the "stuff" out of them since you're limited to a total of 1020Watts.
-12v rail tolerances are 11.4v to 12.6 and I haven't hit either

Cons: -PSU tester didn't like the slow startup time of this psu but it doesn't hurt anything on newer boards.

Other Thoughts: 40Amps is 480Watts per rail max, but one 290x card per rail (about 200watts a card) won't hurt anything and with 3 cards you should be able to overclock 3-290x's to your hearts desire.
12v rail tolerances are 11.4v to 12.6, thought I'd reiterate this since someone complained about 11.7v being too much droop..
If you run a 295x2, Titan Z or a 7990 you need to run them on two rails as you'll be hitting a single rails max especially when overclocking.

I owed these guys a new review since I didn't read their rebate form properly and gave them a bad initial review

GIGABYTE GA-Z68XP-UD3 LGA 1155 Intel Z68 HDMI SATA 6Gb/s USB 3.0 ATX Intel Motherboard
  • Verified Owner
  • Owned For: more than 1 year

Pros: -When it doesn't crash it's great.

Cons: -Random crashes, see other thoughts
-RMA'd and they sent it back saying there was nothing wrong with the board.

Other Thoughts: I'm pretty sure something failed that handles the memory as crashes way more often with two or more sticks of ram and 2 of the four slots crash more often with a single stick than the others.
I first had issues with the boot looping, then the bios update fixed that for the most part.
Then came random crashing when I gamed, so after fighting with the board and testing it with dos mem testing (which caused it to freeze with no codes) I just bought a deal for a Biostar board that was used since Biostar carried their warranty over.

Needless to say the same components on a new board worked flawlessly, I then moved the same components to another board as I upgraded which was an ASRock and it had no issues either.
So I have now lost the cost of shipping on top of having a bad motherboard that's under warranty that the manufacturer won't fix since it doesn't show in 10min of testing.
I won't be buying Gigabyte again or listening to tom's hardware review advice.

PowerColor AX7950 3GBD5-2DHV4 Radeon HD 7950 Boost State 3GB 384-bit GDDR5 PCI Express 3.0 x16 HDCP Ready CrossFireX Support Video Card
  • Verified Owner
  • Owned For: 1 month to 1 year

Pros: -Been almost a year and no issues.
-Mine overclock fine for the price, 1140core and 1500memory on water it was 1125core and 1350mem before on water.
-Drivers have improved significantly a while ago for crossfire especially.
-Still fast enough for any fps game I throw at it BF4 and COD Ghosts run max/100+ fps on most maps.

Cons: -They do get hot if you have bad air flow, I mean the heatsink is dinky on these so sandwiching is a nono, I'd say sandwiching any card is a nono when overclocking anyways.
-Drivers were bad.

Other Thoughts: Bought these for $540-$20rebate with 8free games so for about the price of a 770 around the time of purchase (780 now) and more power than the 780ti.
When you overclock these a solid chunk you have to disable ULPS and PowerPlay, also increase the power limit since these things will throttle the card.
