ok so i went with the core i7 920 and an hd 5870 but held off on the psu because i want quality/performance/value. and the ocz products just dont look like they are good enought for me so ive finalized my choices between these two units. that is unless you have one to mention that is a good price under $120 and a good tier 1 or 2 product.
the choices ive made are both tier 1 products based on this list.
I'd stay away from recertified products, especially with a PSU. The Seventeam also only has 2x 8pin connectors, so if you ever wanted to CF your 5780, you'd have to use adapters (not the best choice) or replace the PSU.
btw in case if you didn't know, you cant just add up the two 25s and call it 50, as those are "virtual" rails and thus share components, and will have a shared max output, which is 450watts. and not 600 watts like delluser said or you alluded to
corsair usually have better products, as they rate their stuff at high temps than others
did you ever brought a high high end platform with CF and SLI in mind?
if not then chances are great is good enough for you, the OP is looking at 920 and 5870, given those facts then perhaps the top of the line excellent is perhaps more appropriate than a great solution that works well for 95% of the population.
also DOA and other aspects to me are minor, as every company has them, you can't control how the delivery guy throws ur stuff around, but the general build and quality you can try to control
if he was lookign at a Athlon II X2 or a Celeron with IGP, do you think I would be suggesting a corsair? Chances are a no name can power it and still not die.
The OP did not mention anything about crossfire my friend and I even said in my first post that if he wants to crossfire later on I would recommend a quality 650w+.
And since this post isn't about whether "I" bought a high end platform with CF and SLI, I have no idea how that's relevent to the conversation.
The psu I recommended is more than adequate for the system he is building and is MUCH cheaper than the one you recommended. It's 80+ certified and It's also covered by a 3yr cross-ship swap out warranty. I'm sorry if that offends you.
not at all, but looking at the parts he chosen, there is a higher likely hood of him running a top end system than someone whom is going to pick say a 5850 or a 5770 or a i7-8xx series on 1156, and with that in mind something that is as top of the line would be needed, the absolute best of the best, which isn't OCZ at this time.
look at it this way, a i7-920 costs ~300, a 5870 costs ~400+
unless you want to get a HX1000 sitting at around 200 something, then the price delta offered by these separate brands is very very very small % of the overall build cost.
if he was choosing between a 4870 or 4850 (difference of around 40 dollars) then hell, get the OCZ and forget about the corsair, or maybe even grab a 420 Watt antec or something in the 40 dollar or less range (while still having a quality PSU) and shoot for a 4890 or a customized version of the 4870
and why did I ask about the high end platform? It's because "I've never personally ever used a Corsair psu and I have had no issues with cheaper power supplies. Most of the computers I upgrade have cheap Coolmax, topower, and coolermaster psu's and nearly every one of them still works after years of use." and that to me brings your personal experience into the equation, I'm sorry if that offended you.
Delluser called it right at the top of the picture. 37.5a available on the total 12v rails. Each individual rail has it's over current protection set to 25a. But they are both powered off the same main rail that is only capable of producing 37.5a total.
Newegg reviews are dangerous to use as research for a few reasons. If the author has low expectations or needs, then most anything will work and wow them. DOA rates are a little more reliable, but you have no knowledge of total sales vs reviews reported back. And if you read some of the reviews and the gross errors in understanding of the way components actually work and see everyone put high for their knowledge, takes all credibility and throws it out the window. I also have a SCCF review and had no problem with my rebate. How do you trust one over the other? You can't, so user reviews should be cautiously used and not cited to make a point.
It is design by design for each brand. The same OEM platform can have different parts picked by different branders and different results even though they are sister units under the logo.
While OCZ does meet my minimum requirements for a quick pick PSU (active PFC indicates corners aren't cut and 3yr warranty to back it, OCZ swap is a very nice feature,) I wouldn't consider them tier 1 and without a proper load test (not voltmeter like newegg users have) probably wouldn't throw them tier 2. I did place the OCZ gold at rank 1 for the 76+amp section because it deserves it. The OP wanted tier 1 or 2, so I checked a known tier 1 or 2 PSU that gives the option for CF and is in line with the other parts picked.
As for how much power to pick, most PSU are most efficient near 50% capacity. I'll usually try to plug a PSU that would be running most efficient for the current build and then have room to grow even though efficiency might not be as good with the extra parts. Better efficiency = less heat = longer PSU life.
