Help Choosing PSU and Case :S

Hey guys,

So I went to the store to get a Coursair Professional Series HX750 Modular 750W for my new build. When they knew about my build, they told me that 750W was a very bare minimum, and that I should at least go for 850W, or 1000W for more headroom.

Really? Well, here's what I have:

Mobo: ASUS P8Z68-V Pro
CPU: Intel Core i7 2600k
Cooler: Cooler Master 212 Evo
GPU: 2x EVGA SuperClocked 01G-P3-1563-AR GeForce GTX 560 Ti
RAM: Corsair Vengeance Blue 8GB

Their suggestion: Cooler Master Silent Pro 1000W

Any suggestions for a better PSU with good headroom under $159.99? Preferably from Canada Computers so I can buy in-store. 

I plan on gaming, video editing, animation, drawing/painting, and possibly recording/editing music.

Also, I am looking for a case that can fit all the parts inside and with good airflow under $75. Better if it had a window and I might go up to $90 IF I have to, but space and airflow are my first priority. Preferably from Canada Computers as well.

Would very much appreciate your advice! Thanks

Regular 560's Sli use under 300W.

Leaves quite a bit of headroom,not too mention the fact the HX-750 pushes out over 900W stable.

I own the HX-750 btw.
CM Silent Pro is good but the Corsair is a higher quality unit internally.
Antec Nine Hundred Two V3 = worth it

Coolermaster Haf 922

I could be wrong though since those cards are new and Nvidia isn't known for low power consumption.
Yep i'm mistaken those cards are power hogs = one card uses over 300W = BRUTAL!
Antec TruePower Quattro TPQ-1200

Another option.

Best option would be the Antec 1200 V3 or DF-85 with CP-850. Jonnyguru says this about the CP-850 when giving it a 10.0 performance rating.

It is completely unmatched by any ATX unit on the market I can think of. You'd have to spend twice as much as this thing costs to find the next best thing, performance wise.


I have built 5 boxes with twin OC'd 560's in them (all at 1000MHz +). I have put a 850 watter in every one of them (3 - CP-850's / 1 - HX850 / 1 - XFX Black Edition). A 750 will work but it's not only about powering the cards, it's about providing rock solid stable voltages on all rails while doing so. Having a bit extra headroom means less heat and less strain which translates into more stable voltages.

Getting that last 0.1 or 0.2 Ghz out of ya OC depends on stable voltages..... when the MoBo is scrambling to correct voltage variations coming outta ya CPU, it's much harder to main stable voltages. The ATX spec is 5% +/- .... I look for 1%. Look at how little the CP-850 varies....

3.3 volt - 3.27 - 3.35 (-0.9 % / 1.02 %)
5.0 volt - 5.00 - 5.06 (-0. % / 1.20 %)
12.0 volt - 11.92 - 12.03 (-0.7 % / 0.03 %)

And less not forget capacitor aging which occurs even on the very best CPU's.

Electrolytic capacitor aging. When used heavily or over an extended period of time (1+ years) a power supply will slowly lose some of its initial wattage capacity. We recommend you add 10-20% if you plan to keep your PSU for more than 1 year, or 20-30% for 24/7 usage and 1+ years.


I use 15% on a 10.0 rated PSU, lower with lower ratings.

2nd Option would be the HAF-X w/ HX850 but it's significantly more money.

Hmm the Antec CP-1000 sounds a bit cheap for a 100W 80+Silver PSU, sounds like an awesome deal but a bit suspicious, like too good to be true. Are you sure that this is better than the Silent Pro? One of the tech support guys over there even told me the Cooler Master is better than the Antec. I found that a bit strange since everybody online prefers Antec over Cooler Master.

Also I'm trying to find a case lower than $90 or $75

No you don't need more than 750w, although personally I would go with an 850w like Jack mentioned if you don't mind spending a bit more just to have a lot of headroom. Do you care about the PSU being modular? This 850w is a great price if you don't need it to be modular: http://www.newegg.com/Product/Product.aspx?Item=N82E168...

Yeah you're right about that. Though wouldn't it be better to get what davcon suggested? An extra 150W for a few more bucks, right?

And again, I really can't afford more than $90 on a case :(

It certainly does sound like a great deal.

Okay, so far I'm tied between your XFX Core 850W and davcon's Antec CP-1000. Which one is better? And I plan on really using the most of my computer.

Just to let you all know I want a PSU that can handle future upgrades.

Awesome find, dude! I looked at the other suggestions on that page and found this:
http://www.newegg.com/Product/Product.aspx?Item=N82E168...
It's $10 less but the one you found sounds bigger


it's actually $7 more and two steps down

it goes PC-K57 (the one you linked)

PC-K58 for $69
http://www.newegg.com/Product/Product.aspx?Item=N82E168...

PC-K59 (the one I linked) for $69 plus promo code LLBlowOut for an extra 25% off, total $52 out the door

all three are great cases but the one with the most features is currently the cheapest one, until 11/23

I was choosing between the corsair 400R (very good case @ $100) and the PC-K59 (at the time, $100 also). I ended up with the corsair but if the lian li was on sale at the time, it would have been a no brainer.

Okay guys, so here's the update so far

For the PSU, I'm probably getting the Antec CP-1000 1000W for $135.38 instead of the XFX Core 850W for $119.99. Simply because it's Antec, 150W more, modular, and only an extra $15.

And for the case, I'm going with dirtyferret's suggestion since his is the only under $100, not to mention the discount.

So I will order these two some time this week. If I'm still making poor decisions, please tell me ASAP!

I would also like to thank you all so much for your help so far. I will be solving this thread soon when I'm done! :) 

Edit: got mixed up with Youngster's and dirtyferret's names, sorry! :p

that sucks, check out the antec 300 illusion and cooler master 912

both are good budget cases. the antec offers better out of the box cooling, the CM offers a bit more interior room with its removable HDD cage
