the above part, it's actually the other way around. it's not wrong at all because it really is about % of power draw reaching the computer.

i would have put it .....

If a computer drains 400w, then an 80% efficiency PSU would theoretically draw 500w from the wall.

because it's from the components, telling the PSU what they need, and the PSU then draw from the wall.

anyway, nice thread pinned.

in case you guys didn't know yet - i have an ESTIMATOR available http://www.goldfries.com/power-supply-watt...n-graphic-card/

there's also a PSU wattage calculator and the above on my Facebook page last time, I've disabled temporarily due to HTTPS issues.

guys - just to clarify.

As long as PSU has detachable cables, they're MODULAR PSU.

Semi-modular PSU are still MODULAR PSU, just as Full-modular PSUs are.

Please don't ever go around saying Semi-modular is not modular.

In the past, it's always been called modular. Just that with recent development - 2 new terms appeared - SEMI Modular / FULL Modular to differentiate those with ATX cable being detachable.

it depends on the PSU upgraded to.

say your load is at 350w.

for 650w, your 350w is 53% power load
for 860w, your 350w is only 40% power load

going by the graph below (for example)



it makes no difference.

but the efficiency improves at around 45%.

should you aim for 45%? no, waste of time.

the graph is exaggerated.

if you mark those points, the rated efficiency difference is like 0.5% despite the curve shown.

furthermore your computer isn't on full load all the time so you're on average, still stuck on the 20% load part.

good budget, just stretch it a bit and you can get a Seasonic 620W M12II

CX500 is old stuff. I don't think you can find it already.

really?

my CX500 served me for years and served me really well.

to backup my experience, here's an article from THW.

Yes, I'm aware that there are multiple variants.

It would have been more helpful if you just included a few words to highlight as what you highlighted.

It's exactly like what you said,



and exactly like the one in your link.



which in my opinion doesn't make it not good.

interestingly a lot of people also highlighted FSP Hexa 500w and all for gaming but from my personal test, it didn't handle well when I run an R9 280X on full load for long period while my Corsair CX500 and Corsair VS550 could do it with no issue at all.

I'm going to throw the same test on my FSP Hexa units again soon. Since I have 2 units of it, I'll get to see whether it's the same across multiple products.

let's see how soon my VS550 dies. Stressing it quite a fair bit.

my CX500 die already, after 1 - 2 years usage, not full load but somehow the ATX part melted and 12V is under delivery.

I wouldn't worry too much about PSU. Most of them are ok for general usage, it's those who run on high load and such (Eg overclockers) then the demand would be more into those finer details.

but hor, that one is 2008.

Many things would've changed through half a decade.

wattage is just one part. a typical user won't even reach 400w, even with 250w card and 100w cpu.

the issue is more about constant load, in some cases even running a burn in test on graphic card alone would trip the PSU.

RM 150 PSU, regardless of what brand, I wouldn't dare to put them on 24/7 full load like say folding@home and such. nothing more than gaming.

Welcome to the other side of the world!

Yup, efficiency is pretty much flat across all loads for quality PSU.

Example :
FSP Aurum PT 1200 http://www.jonnyguru.com/modules.php?name=...Story3&reid=398
Seasonic SS-1050XM2 1050W http://www.jonnyguru.com/modules.php?name=...Story3&reid=401
Corsair HX1000i 1000W http://www.jonnyguru.com/modules.php?name=...Story3&reid=394

Even a 300w would suffice for that, get a good 400w would work just fine.

can try the FSP Hexa 450w / 550.

acceptable is one thing but can you be sure that the distributor wouldn't just abandon it overnight?

I know FSP, Seasonic and Corsair's distributors doesn't seem so but I can't say the same for Antec.

That FSP Hexa would work just fine.

I think the AeroCool KCAS works just fine but brand vs brand, FSP would be the better one. They're very reputable across the globe.

It's funny when I see "DO NOT SKIMP" and at the same time recommending the lowest of the lowest of low in FSP's range of PSU.

A good 300W can handle Xeon CPU and 750 Ti easily.

A Xeon 1231V3 and 750 Ti on full load doesn't even touch 66% the capacity of what a good 300W can deliver and a good 300W

A Silverstone SFX 300W as this http://www.silverstonetek.com/product.php?pid=458 would still be of higher quality than the FSP Hexa+ 550W.

Not worth doing at this point of time.

not PSU issue.

have you tried other CFX cable?
