Thanks! I have a 300W power supply, it doesn't look very beefy either I think I could easily fit a bigger one...should I go get a 500W?

[LiveBrianD]

To add to that, what brand, wattage, and 12V rail do your PSU have? A cheap generic 500W unit won't be able to supply as much as a Corsair 500W unit, for instance.

[cooldude91]

LITEON PS-5301-08HA, RoHS, 300W,
INPUT: 100-127 ~ /8A 50-60 Hz
OUTPUT: +5V DC /25A MAX. +12V DC /19A MAX. +5Vsb DC /2A MAX.
+3.3V DC /18A MAX. -12V DC /0.8A MAX.

COMBINED POWER ON +5V AND +3.3V RAILS NOT EXCEED 175W MAX.
COMBINED POWER ON +12V AND +5V RAILS NOT EXCEED 268W MAX.
CONTINUOUS TOTAL DC OUTPUT POWER SHALL NOT EXCEED 300W

Okay. You are definitely going to need a decent PSU. You are going to want at least 25a - 30a on the +12v rail(s). You can get that and more with a Corsair 650w PSU ( 52a on the +12v Rail ).

Yeah, a 19A 12V rail, 300W total PSU won't cut it. Ati recommends a 450W unit for a 5770, probably 400W realistically. For the 6870, they say 500W, maybe 450W realistically? (they tend to overestimate by quite a bit, and I'm sure I'm still looking for more wattage than actually necessary). Personally, I like my Seasonic S12II 520W unit (40A 12V rail), nice and quiet and stuff, and I believe there's also an Antec Neo unit that's based on the same design, $10 cheaper. 520W should give you enough for most mid-range to higher-end cards.

I started looking into my supply. There is a topic, someone has a similar pc build as me, mine is an HP HPE-410t.
People are suggesting on threads a good upgrade would be the:

CORSAIR CMPSU-650TX 650W ATX12V 5.9" x 3.4" x 5.9"
Silverstone Element ST50EF-PLUS 500W found this review. http://www.jonnyguru...p=Story&reid=13
Rosewill RP600V2-S-SL 600W ATX12V v2.01 SLI Ready PSU 5.91" x 3.39" x 5.51" $40 cheaper than the Corsair650

thoughts?

I'm a little wary of Rosewill, but the other two may be fine with a single card.

The Corsair should be fine for 2 mid-range cards, the Silverstone fine for 1 mid to higher-end cards, but I wouldn't trust Rosewill. Remember, a cheap or bad PSU can blow up, taking your entire system with it.

I realize the power supply is not something I want to cheap out on, that's forsure. Leaning towards a single-rail Corsair 650W now, unsure as to which model would be best for my rig but it seems to be the best choice...Also I live in *gulp* Canada so I don't know which outlet would best to buy from, except for maybe tigerdirect.ca

Canada? Well, at least you don't have tea partiers to deal with. JK!!!!! Sure, something like a Corsair TX650 is good, and has enough wattage for just about any single gpu, or 2 mid-range ones. btw Seasonic, Antec, PC Power & Cooling, and Silverstone are also good brands. newegg.ca would probably be a good place to buy stuff, as newegg.com is pretty popular in a lot of tech communities it seems.

[cooldude91]

Okay, so one of these power supplies will be the one i'll be buying:

http://www.newegg.ca...N82E16817371044
http://www.newegg.ca...N82E16817139005
http://www.newegg.ca...N82E16817139020

One question, the older version of the corsair says SLI/CrossfireX certified and i7 compatible but the newer version(V2) does not say, would it be safe to say the V2 version is also? Also this Antec EarthWatts seems alright and has low standby power consumption so it could also be a viable option. Thanks for the valuable input

[LiveBrianD]

I don't see any difference between the corsairs, except one is cheaper (and a newer model). The Antec EW is slightly more efficient than the corsair (claims 88% vs 85%). However, the corsair has one 53A 12V rail (636W), while the antec has 2 38A ones (650W combined maximum though, so you can't have both rails at max capacity at once). That could make a slight issue - rail balancing. Personally, I would go for the Corsair because of that.

However, what kinds of gpus do you plan to be running in the future? (I want to leave some upgrade room, but you don't need a 650W unit unless you're running a high-end GPU.)
I did a little searching around and also found:
http://www.newegg.ca...N82E16817371031 - Antec Neo 620W - 80 plus, one 6-pin PCIe connector and one 6/8pin PCIe, $70
http://www.newegg.ca...N82E16817371048 - Antec High Current Gamer Series HCG-620 - 80 plus bronze (bit more efficient), 2 6/8pin PCIe connectors, $80
Both have 48A 12V rails and are a bit cheaper than the ones you mentioned. As I said, I like my Seasonic S12II, the 620W version is $86, though I don't think you get anything more over those Antecs, and this has a lot of wires to manage (I ended up moving my optical drives down one bay so I could shove all the cables in the top, now empty, bay. My case has the PSU mounted on top.)

You would be safe with any of the above. I have a couple Antec EW PSUs in my home, both do perfectly fine.

As another option to consider, namely because the prices are so close: PC Power and Cooling Silencer 750

Please think about that statement a moment. NONE of those PSUs are capable of 912W on the 12V rail. Of course you aren't going to be able to draw 38A on both at one time... Because the PSU isn't designed for a 76A load. The 38A limit on there is for people who honestly think that multiple rails will somehow limit the amount of power feeding their devices. The Antec would work perfectly fine in the OPs system. Shoot, I doubt any of us could create a problematic load for that sucker.

EDIT: BTW, If I am coming off harsh tonight, I am sorry, just a bit tired...

Come to think of it, how are things spread out if there are 2 12V rails? You know, motherboard, CPU 8-pin, SATA power, Molex Power, PCIe connectors for the gpu, etc...

Very likely - 2 PCI-E on rail 1 with the CPU, and 2 PCI-E on rail 2. I would think it would be set up so the 8 pins are both on rail 2 and the 6 pins on rail one. Then devices split between them...

This would create a realistic max load of 24A on the first rail (130watt CPU + 150 watt PCI-E), and 25-30A on the second rail. Assuming 300watt in PCI-E + devices.

Got well over 40 Hrs in Syrim and ahd barely scratched the suface in my exploring. Believe me, there is plenty to see and do for sure.

Thought I'd put up a few screen shots :

OK, after fighting this machine for what seems like forever, I finally dropped the resolution.

/facepalm

The problems cleared up entirely. This game is silky freaking smooth @ 1080P. Either it doesn't like the odd resolution of my monitor, or it is actually hitting VRAM limits. I am guessing the latter rather than the former. Amazing game!

And now I understand where the phrase came up: "...then I took an arrow in the knee" For the life of me, I kept hearing it and wondering, until I actually got a chance to play a few hours. Then it took a while to stop laughing.

That phrase sure seem to be making rounds. Just ran across it again:


Ignore that...Cases serve a purpose. Blow heat the other way and the BUILD (case) will make up for it.

Wow. I step out and everyone has a degree and solid use in thermodynamics. I was just watching that molex connector move. MasterChi...snap a board? Really? I use to guess about stuff, but I took an arrow to the knee...and still think that's silly and empty gestures toward physical properties that don't exist.

It's alive, it's fine, and works. Fine tuners need references or Resumes. Or critique the build! See all those ports the case the gets all those Water cooling points for with air cooling...going unused? Wiring can use those, but don't here at all. That bundle can happen where it is not seen, taunt lines can go way, and it's still something slapped together. Just saying, that taunt line would have me tear it all down again to give it some slack. Give it an actual full weekend, then it's a clean build.

But yeah, it works fine right? Run it. Don't let randos start preaching temps and stuff and get away with it so easily. Give me something to talk about, question them all, and we can get this forum back into order. Snapping boards and direct flow suggestions...take that
