hehe..raidmax got psu meh?....never heard b4..lol

coolermaster iGreen psu, any good? thinking to get used one..

-adios-

Coolermaster?
One more brand that is in my No-No list.

Refer to the first post lar, why you wanna get those psu's that is not even in the tiers?

haha..
cheap mah..
rm230+ only.. others out of my budget..

-adios-

Exactly. Cooler Master PSUs are meant for the budget strapped. They're good value for money and easily available yet are reliable enough for overclocking to some extent (don't push it though). Works the other way too, meaning that there are better options which cost more.

Check out if the following sites have reviews for a PSU that you're targeting to buy. Unlike most sites which just hook up a PC and use the onboard system monitoring to check voltages (which are FUBAR for the most part), these guys test it with electronic loaders that will really load the PSU to the max. The links are to the pages that describe how the PSUs are tested by them.

I will soon compile a list of PSU's which reliably meet the ATX specification (meaning the manufacturer isn't lying about the ratings) based on reviews on the sites that I've mentioned. However, how well does the PSU actually help your PC, hard to say. Overclocking is better with PSUs with better voltage regulation, but how much better is difficult to say for sure. Not enough watts is usually not the issue for most overclockers (in particular those who can't afford the most extreme hardware from the start) because, assuming the PSU ratings are accurate, the 400-600W usually bought by overclockers is a bit overkill as most systems (except overclocks of above 3GHz) actually end up with less than 300W power consumption for non-SLI/Crossfire sets and less than 500W for non-SLI/Crossfire sets. For some reason, above 3GHz processor power consumption jumps up rapidly, regardless of which processor it is.

good point u have there..
I think this cm psu is enough since i'm not xtreme overclocker..
huhu..

-adios-

u can get Acbel 450W cost RM240.00 at Prestige IT, Low Yat ... that what the catalouge says la ... i'm also searching for psu ... have glance through many catalouge oredi .. hehe

Bro, in case you don't know,

Cooler Master = Acbel

Even the sticker is a giveaway if you examine it. Exactly the same grammar mistakes on both.

Well, i used CM Real Power before. Not having much reliability issue before. Just that the voltage fluctuate a bit when you are doing OCing. I am not a hardcore OCer, and only push what my mobo allows me to. No changes done to voltage and etc. But you can see the fluctuation in the voltage of the PSU.However, no dangerous issue as its just minor fluctuation..

I guess if you are not those hardcore OCer, this PSU can serve you well at a good price. I am sure the IGreen series is better than the Real Power which means, the IGreen series should be a good buy as well if you are tight on budget...

Question on my PSU - Enermax Liberty 500w.

CPU-z shows my Vcore fluctuation - normally at 1.344v but will fluctuate lowest 1.332v and highest 1.356v.

Does a good PSU show this fluctuations on CPU-Z?

I am not sure about CPU-Z but from the stuff that i read before, a good PSU should not show frequent fluctuation. A good and reliable PSU should be able to show rock solid performance with the least fluctuation possible even on hardcore OCing..

Ya, I know. Other apps like speedfan or RM cpu clock would show a stable Vcore. Just the CPU-z always shows fluctuation. Anybody using CPU-Z can confirm whether the Vcore fluctuates?

If so, the my PSU not a good overclocker PSU!

I thought Enermax is a good PSU with OCing potential..Maybe its just CPU-Z showing trouble..lol..Dont be too afraid..

Ya, Enermax is a good PSU. However, I think my model is not the ones overclockers will buy. Reason I bought this one was because it is modular (can unplug those cables that I don't need from the PSU).

The reason I ask is because my X2 runs stable at OC 2.69 Ghz. But once I OC at 2.70 Ghz, Orthos will fail. At first at 30 mins, then at 5+ hours and lastly at 7+ hours.

Ya, I know, I can easily up the Vcore a bit but that would increase my core temp to around 60'c. So, I'm thinking it could be due to my PSU vcore fluctuation......

Ya, I also know that 2.69 Ghz is already more that I could ask for but of course, everybody wants the best potential for their rig right?

owh...notice that before ... thinking it's not really important coz many good review about Acbel than Cooler Master .. maybe i should take a look at CM also la as i'm also really thight in budget ...

CM might not be in everyone's list but personally, they are a good PSU in terms of price point. Its a PSU that offers good normal performance at an affordable price.However, given the possibility, do not look at those Extreme Power series. To me, i dont think they are reliable enough if you are running a power hungry rig..

AFAIK, acbel is OEM for cm realpower 450W, means that acbel ipower 450W and cm realpower 450W is actually the same..

-adios-

oh..my cpu-z also show fluctuation..around 0.01V also...

Not necessarily true. The processor voltage is regulated by the motherboard, not the PSU. Although the PSU does effect it to some extent, from my knowledge of voltage regulation circuits it will take one hell of a PSU fluctuation to overcome the CPU's voltage regulator on the motherboard.

Cooler Master and Acbel PSUs come from the same factory, same circuit design. Only different packaging.

The 380W and 430W extreme power models have been tested by johnnyguru and found to be reliable. However, he found the 500W one to be unreliable.

Its the same circuit, if you actually bother to examine it.

so, does it means that the performance is actually the same?

edited : why the 12V+ rails is different meh? acbel 20+21A but cm is 18+16A..

-adios-
