Quick question: I had always thought the Z68 chipset needed a SSD and also wasn't quite as efficient at OCing-- I take it both these thoughts are wrong and I don't need to buy a SSD and Z68 OCs well? I'm more a fan of a dedicated GPU until SSDs really start blowing my mind. And I always thought my PSU was overkill (seemed like it would only max out at 300, if that) so it was very good to see you support that. Thanks. | ||

No you don't need an SSD. Z68 has options for SSD caching but like all enterprise technologies, its doubtful you'll ever find a use for it. You'll get more shoving everything onto the SSD you were going to cache than using it as an actual cache. | ||

A core i5 2400 uses roughly 55w while a 6870 uses roughly 130w, this configuration will have a hard time breaking 200w, yet alone even come close to 600w. From a different thread, but is this true? We have a prebuilt Acer computer with an AMD CPU that according to calculators uses the exact same amount of power as a i5 2400. The power supply's 300W, there's like 2 led lights 6 MB of ram one HD. It has only an integrated graphic gard, now my question is, would it be safe for the power supply to change into a 6850, as the calculators recommend a PSU closer to 400W? | ||

Did you use an online calculator to determine the max power draw of your Acer system? Whatever AMD processor you have in there is very, very likely going to be drawing a significant amount more power than a i5 2400. To use Tech Report's results as an example, an Athlon II X3 draws 140W* while an i5 2400 draws 110W* during a typical render job. Phenom IIs are even worse, with some of the higher clocked stock models hitting up to 180W*. *This is straight from the wall. | ||

It would automatically take you to Google.com, the same place most of us would go to definitively answer this question. For SLI, it wouldn't work. For Crossfire, it either won't work, or will work at the smaller number most likely. Seriously, dude, google is your friend, I'm just the guy who groans every time he sees your name on a tech thread. | ||

It has only an integrated graphic gard, now my question is, would it be safe for the power supply to change into a 6850, as the calculators recommend a PSU closer to 400W? Yes, this is true. You can go look at benchmarks or measure from the wall yourself. 268w from the wall: http://www.hardwarecanucks.com/forum/hardware-canucks-reviews/37286-amd-radeon-hd-6870-hd-6850-review-25.html 256w from the wall: http://www.anandtech.com/show/3987/amds-radeon-6870-6850-renewing-competition-in-the-midrange-market/20 265w from the wall: http://techreport.com/articles.x/19844/15 All of those are with Bloomfields. And a 300w power supply from a prebuilt is not the same as a quality 300w you buy from a retailer. The one included in your prebuilt most likely does not provide anywhere close to 300w on the 12v rail, it probably provides closer to 200w. You can run a core i5 2400 and a 6850 perfectly fine off a quality 300w power supply that actually provides close to 300w (24a) on the 12v rail. But good luck finding one that is less expensive than the CX430 V2 after mail in rebate. Unless you have like a single or dual core Athlon than your AMD processor will not be using the same amount of power as a core i5 2400. It'll be using (much) more power than any Intel processor. | ||

It's just the power supplies in low-end consumer desktops (like most people asking have, that are sold for razer-thin profits) that are a bit suspect, and still, none of those are going to be as bad as some stuff you can find on retail like this: http://www.jonnyguru.com/forums/showthread.php?t=6714 | ||

Only reason I am asking is for the new pc build, I'd really like to get an i5 2400 in there rather than an i3, and getting a graphics card now would be over the budget. He already has the 9800gtx. Upcoming games would be Dota 2 and SWTOR, maybe BF3. So holding off on the graphics card for maybe 6ish months be alright?

$25 for a single 4gb module is expensive... heatspreaders don't do anything besides looks fancy so unless you really want to waste $5 for aesthetics you'll likely never even see ever again, you can get it instead of a $20 module: http://www.newegg.com/Product/Product.aspx?Item=N82E16820231421 There's probably some core i5 2400 + memory combos as well. Earthwatts 430D is overpriced. You can get the Antec Neo Eco 520C for the same price ($45 after mail in rebate): http://www.newegg.com/Product/Product.aspx?Item=N82E16817371030 If you want to deal with adapters when you upgrade your GPU than you can get the 400w variant. | ||
