Coolermaster extreme PSU? Meh, I'm just superstitious...

 

A few days back the 430W earthwatts was 30bucks at newegg! Free shippin too.

 

Now it's more than double, without the rebate... :S

 

the one i had sam was a good PSU just the fan was so damn loud. bigwill has it now.. he took the fan off of it and replaced it with one of the blue led 120mm cant hear it run now.

the one i linked to (well no link) is the new extreme power PLUS.
they have these over at my microcenter in a CM590 case and you cant hear it run at all. im sure if it has enough juice to run bigwill's system it can handle the one im gonna be building for MOM in law.

plus i can get it $8 cheaper at microcenter and not pay shipping on it.

the $44 one is the one i had.and is loud....

 

Ah right ok, looks like they did sort those units out then...

 

yea thats what im hopeing for anyways..lol

yet to hear back from her. im kinda excited to do another build.let alone a AMD one...

 

rob,

I would reconsider the psu. I would go with a corsair VX450 instesd. I really like cm cases but I'm not too fond of their psu's. lets compare:

the VX450 is less money after shipping and MIR http://www.buy.com/prod/corsair-vx-...-atx12v-eps12v-power/q/loc/101/205466485.html $55.74 vs $60.86 for the coolermater 550 http://www.newegg.com/Product/Product.aspx?Item=N82E16817171031

the corsair is up to 85% efficient where as the coolermaster is only 70% efficient.

the corsair has a 5 year warranty where as the coolermaster only has a 2 year warranty.

here's the specs for each. compare for yourself. corsair 450 http://www.corsair.com/products/vx.aspx coolermaster 500 http://www.coolermaster-usa.com/product.php?category_id=27&product_id=2745

 

is the 450w enough power?

 

Quick Question :A 12v line is a 12v line, same with 5v. My question is aren't amps more important ? Higher is better! RIGHT!
I know if U hAVE a 100 extention cord a 12 or 10 gauge wire will run cooler then a 14 or 16 gauge. I'm pretty sure this has something to do with the AMPERS & the draw on the power. Another thing if U have a 20Amp breaker & run something that requires 30Amp, it will get hotter then Haddies and eventually kick off. Does not the same principle apply to Computers

 

Not exactly, rather than run 'hotter than Hades' it will simply shut down when you overload it, or if you have a cheap PSU, it will run hotter than Hades, and promptly melt, go bang, catch fire, or any combination of the three.

 

cincyrob,

More than enough for a stock machine!

plenty for no more than what you're doing with it. actually a 250 watt psu would suffice although I wouldn't recommend it. even a good 350 watt psu would work fine for what your doing.

edit: sorry russ, you posted while I was typing.

 

A 250W PSU could have run my gaming PC when it had the overclocked E4300 and HD3870, I wouldn't do it, but that shows, a stock machine will run on a basic PSU. AMD CPUs do seem to use a lot more power than the Intels though, so having an ample PSU is always wise.

 

:O - nice work!
Is that an Optiarc drive I spy in the picture?

 

sammorris,

They are both 65w, so I don't see how it can use more power. AMD MBs don't manage power as well as the Intels, but the CPUs draw the same watts! At least anything comparable to a 64x2 5200+ does!

TDP is not how much a CPU actually uses it seems, far from it:



The TDP of the 6000+ is at worst 125W, and the TDP of the E5200 is 65W, so that puts the CPUs themselves 55W apart. Taking a worst case scenario let's say the AMD chipset uses 30W more (unlikely), and factor in poor efficiency of 75% for both the motherboard regulators and the PSU overall. That leaves us with a big gap, but not the 145W more that thetechreport experienced.

More to the point, the E8500 and E7200 are 19W apart and they have the same TDP...

 

I'm glad we're finally talking about AMD's. I've been thinking of going that route to replace the CPU & mobo I recently killed.
I'll be lurking with interest...

 

After that though, it's a bit worrying. The 6000+ isn't even that much faster than the E7200, it's what, 10% at best? Consider that if for example your PC is at full load for 30 hours a week, and idle for another 30, in the space of just a week you use an extra 5.4 units of electricity. Over the space of a year, 280 units, which is what, 50 dollars plus? Over here at least it'd be 40 pounds, and that's more than half the cost of the E7200 itself.

 

sammorris,

He's not going to use a 6000+ unless he changed his mind, he listed the 64x2 5200+, which is 65 watts not 125! CineBench shows the total watts used by the computer, not just the CPU. The are implying that the Intel chips are more efficient, when they are not! The chipsets may be more efficient on the Intels, but that has nothing to do with the CPU! It's total nonsense! The total energy used depends a lot more on the power saving abilities of the MB, than it does on what CPU you use! 65w CPU power consumption is 65w of power the CPU consumes! Unless you overclock either CPU, it will only draw 65w! The AMD motherboards just aren't as power efficient as the Intels, and has nothing whatsoever to do with the CPU if the wattages are the same! The 6000+ at 125w, would draw more power and make more heat! The 5200+ is the better chip for the use intended!
