The issue and talk of PSU's have been very much over-rated throughout the years. Undeniably, hardwares today need more power but this normally apply to top end graphics card or perhaps if you have plenty of fans. The good old hard disk and DVD-ROM doesn't need an extra 30% power to get it running.

Many thought that having a high capacity PSU would ensure a good overclock but in fact, this isn't always the case. To overclock well, you not only need a good chip + RAM but also the knowledge. Trust me, it's not always as simple as bumping the voltage and increasing the memory bus; it takes more than that to get the best out of it.

You have to see what type of hardwares you have on your PC and get a PSU according to your needs. There's no point investing on a 500W-600W if you have a simple setup like mine (1xHDD, 1xDVDROM, 3xFans).

A simple experiment - use a 350W and later swap with a 600W to see if it gives you a big difference. Technically, I'll be getting better numbers on the rails, lesser ripple effect, etc but note that many PC's run on cheap Icute or unbranded PSU's and able to survive for years. The only time PSU might kill your hardware is when it's really under-powered or it's too old.

If you have plenty of hardwares, top of the range graphics card which is power hungry then it makes sense to get a "big" PSU. My word of advice is don't just get a 500-watter because everyone says its good (especially from the review sites). Get a PSU which suits the hardware in your PC.

At my point here, I suggest you direct get Acbel Power Supply over than 600watt if you wanna use for overclocking. I here use Acbel i-Power 450watt already 2 years+, no problem at all. So, damn nice for this... Trust Acbel for quality & performance.

Get R8 Series:)

Efficiency over 88% as they claimed.

Freind, I doubt that Acbel is a good OC PSU.
For that price you can buy Silverstone ST56F at RM330, which is used by many OC'iers here.

DevilMan, I'm running on a cheap 390W Acbel CPU and doing 8 x 410 on my E2140. I believe it can still go further too.

Btw, Cooler Master PSUs are mostly manufactured by Acbel. Even the sticker bears some similarities, even the grammar errors are the same


Silverstone is a good & reliable PSU, BUT only in western countries where the weather is not so hot. Failure/problem rates among LYN members & friends have been high, most likely due to the silent fan which might not be cooling the PSU adequately. On the other hand, Acbel often has better efficiency, even among the non-"80 plus certified" models.

my enermax fma2 just kong already dis week..i dont know why,the system just shut itself while im playing crysis wif my 8800gt..hmm,i'm used it jz one year only,and i'm using it almost 24 hour...so no w i try to get new psu..from my short list,i've decide whether i want to buy sst 560watt or acbel r8 700..??anyone can give some advice or exp using those product??i really2 appreciate

IMHO, the acbel r8 700 is really nice.

Using ST56F, very good and stable PSU for me.

hmm one say sst and one say acbel..huuhu i'm still in d middle..which one is d best???anyone?

Added on November 30, 2007, 7:58 pmbut for me,acbel have lifetime warranty,for me it's worth buying it because have lifetime insurance..correct me if i'm wrong...but now i juz want to which one si better,quality,rocks!!huhu..because i use my comp 24/7..my spec e6600,8800gt,4gb ram..and like to upgrade to quad and sli in future..so which psu is d best overall??

Corsiar hx520, tx 700 , hx620 , vx 550 ... to name a few
Sunbeam Nuuo 550 (using now)( old but super quality even johhny guru say )
SST Zeus 560 , Op1 K ( using now ), Op1.2k
Delta 600~800 wat
Dare i say it, coolermaster 800wat and above
Thermaltake Toughpower 1k wat and above, 700wat and above also not bad..
antec quatro

then some rare brands,

seventeam, etasis, emac/zippy , andyson , Pc power and cooling ,

Added on November 30, 2007, 10:54 pmany of the above will do

is it acbel is better than silverstone or any other model of psu because of its lifetime warranty???

acbel is ok for daily.. but in heavy loiading.. im not too sure... no offence to those using acbel though.

what do you mean by daily usage?actually i'm not a heavy overclockers,i'm just using my pc 24/7.so i wonder,can silverstone handle quad n 8800gt sli?

which silverstone?

Hi guys, my power rating in this calculation shows: Recommended PSU Wattage 501w at 100% peak load with my current oc specs.
http://www.extreme.outervision.com/PSUEngine

but now my psu is ST50F 500w.

is the calculation accurate?
it's scary...

Added on December 2, 2007, 1:40 ami'm not going to buy the low wattage acbel maa..i'm going to buy acbel r8 power 700..so do u think dis psu can't handle heavy load??

erm...
looks like everyone suggesting ST560F for now...
its price more than RM 340 retail...

can this one support an OCed quad core cpu and a 8800gt?

Quite agreed on this..
I used to have acbel 450w..well bcoz of the sentiment of less hardware hdd,not low end hardware kinda of stuff.
i stick to it till.....I get my F3 proc.

what happen when i got to 3.5g??pc shutdown itself!!and a couple of unexplained symptom.
spec at that time 7300gt,2hdd,3fan thats all.

So for now since I have experience on this..i suggest to get at least 500w for daily use with mild oc.
Oh...since i change to 600w as in my siggy.no more unexpected shutdown or weird issue happen ever again! OC result do improve too

The PSU calculator calculates the worst case senario, which is not actually possible in real life (trust me, I've tried it on 3 PCs). At most you'll only reach 80% of the calculated power consumption.

Can, but if you go SLI, either don't overclock or go real easy on overclocking.
