Azza Solanos 1000R case with 6 fans (2x230 2x140, & liquid cooling system added - 2 fans for it)
Corsair H80i cooling system
MSI Z77A-G45 gaming motherboard
GTX 650 ti boost 2GB ram
intel i7 3770K in 1155 socket
Crucial 8 GB low profile ram DDR3 1600 MHz

Any advice is appreciated. Thanks again!

750W is almost overkill for that build, as long as you're using a single graphics card. If you're planning to add a second one in SLI, 750W is appropriate (and still sufficient).

Single rail doesn't matter. Cooler Master isn't all that great quality though, you might want to consider a more reliable brand.

750w is huge overkill for your system...
and cooler master in most cases don´t have very good power supplies...

Is it the Cooler Master GX 750W for $60? If so, that's not a good deal at all. I know it says $60 off, but that PSU shouldn't cost even $60 in the first place. You can get a significantly superior XFX 750W Semi-modular PSU for $55.

Yes it is the GX 750W for $60. Thanks all for the replies so quick!

Let's start with the manufacturer's recommendations:

http://www.geforce.com/hardware/desktop-gpus/geforce-gt...

Quote:
Thermal and Power Specs:
Maximum GPU Temperature (in C) = 97 C
Maximum Graphics Card Power (W) = 134 W
Minimum System Power Requirement (W)4 = 450 W
Supplementary Power Connectors = One 6-pin


So nVidia says 450 minimum, 584 watts for SLI,


Quote:
Here is Guru3Ds power supply recommendation:

GeForce GTX 650 Ti Boost - On your average system the card requires you to have a 500 Watt power supply unit.
GeForce GTX 650 Ti Boost SLI - On your average system the card requires you to have a 650 Watt power supply unit.

If you are going to overclock GPU or processor, then we do recommend you purchase something with a bit more stamina.


So....500 watts for 1 card, 650 watts is recommended for SLI with no OC'ing. If ya OC it's recommended that ya get something bigger so I'd do 600 watts for one card and 50 for SLI. And no I wouldn't use that PSU/

With the Azza at $110-120 on Amazon and $60 extra for the unsatisfactory quality PSU, ya at $170-180 ...

.... The Corsair 500R is on sale for $70 (MSRP = $140)

Ina combo with the jonnyguru 9.5 performance rated TX750 V2, at newegg, the combo cost is $205 - $25 off w/ promo code EMCXMWT39, ends 8/19 - $40 in rebates = $140

So ya can save $30 $40 while getting a substantially better case and a hugely better PSU.

Sorry but I'm not finding the combo package. I already have all parts except PSU, motherboard, & ram.

I like the idea of having room to grow with a 750W PSU since I may do SLI in the future. Keep in mind I am very budget conscious right now.

I may go with this case instead as it's Tom's approved: http://www.newegg.com/Product/Product.aspx?Item=N82E168... . The Azza 1000R case looks iffy to me, thin, flimsy, and fans are suspect once I seen it in person. Azza is $89 with $20 rebate but probably not worth it in the long run. The Phantom 410 seems to fit the bill and video shows it to be easy to open and a solid case. I hope the H80i fits though. If not, it can accommodate another liquid cooling solution as per video. Wish I'd seen it before I purchased Azza's.

I think I'll go with a 750W just so I'm covered and previous mentioned PSU price is ok with me & it being more reputable and recommended. I don't want to take any more of ya'lls time & thank you very much for the input!

Sakkura,

Do you think the H80i will fit in there and not cover up the socket? The video shows the H60 in place nice and neat but unsure if it will cool the i7-3770K enough. Besides I already have the H80i. Looks like a good deal though and I like black too. Or should I just go with the Carbide and H60 as shown in the video? I see the H60 works well there. Thanks again.


Sakkura said:
That is a good case, but it's kinda expensive. Also I'm not into the looks, but that's up to you. The Corsair Carbide 300R is still pretty cheap without a combo, and is a good no-frills case.

It would probably fit, but it's pretty big and would restrict airflow to the VRM heatsink. Might be better to get an H100/H100i mounted at the top of the case. Better CPU cooling and easier to mount since it's thinner.

Alright, looks like it's off to ebay for my other parts and I go with the H100 and Corsair case for the build. Thanks all for the advice! I should be paying for this advice. Wait... did I just say that? Excuse me let me retract that statement...

You guys are awesome and rock. Good advice all the way around! Thanks again!

I am going to venture out boldly saying that the 80+ certified CM supplies aren't too bad.

The Cooler Master GX PSUs are pretty bad. The Cooler Master Silent Pro PSUs are usually decent. Both are typically overpriced.

Here is HardOCPs conclusion regarding the Cooler Master GX 650W:

Quote:
The Cooler Master GX 650W is a mediocre power supply for couple of years ago, and an outright failure today. The Build Quality of the unit is nothing to write home about (unless it is a warning), the topology is old and outdated, and the exterior is flash over substance. Coupled with this we have mediocre voltage, poor by today's standards efficiency, and out of specification DC Output Quality. One upping this poor showing is that fact that the unit was completely unable to complete our load tests at 100v AC input. That makes the GX 650W not just a failure by our standards, but rather a double failure and an ugly one at that. Making matters worse is the fact that this unit is priced at up to $100 in retail and $70 online. (Users can pick up the much better Seasonic M12II-620Bronze from Amazon with Free Prime Shipping for $98.29). As it stands, there really is not anyone that this unit would be a good fit for that we can think of, and certainly not for its intended crowd of "gamers." Cooler Master should be ashamed and owes all gamers and hardware enthusiasts an apology.

The ONLY good Cooler Masters are the new V series made by Seasonic.
