guys,

1. if a PSU stated 500watt true power, does that actually mean the PSU is supplying around 500 watt flat even though we are using only say...400 watt?
OR the PSU is able to supply up to 500 watt?

2. is there any accessory to measure the PSU usage? (dials or meters attached to the front panel or bezel)

regards,

1. If stated 500W, it suppose to supply up to 500W but doesn't mean that if your cpu uses 500W, using 500W is enough. Must get higher than that. Try PSU calculator to calculate your watt used. If you get 360W, your psu used around that plus minus

2. Total watt used, use PSU calculator. Try google

afosz,

thanks for your ans.

1. will PSU regulate the power as in power regulators? a few of my friends told me not to use regulators with a good PSU as in enermax.. it will somehow blow up the PSU.. (it's a hear-say situation) how far is this information is true?

2. how can i check the fluactuation of power in my PSU? what i trying to know is erm... example.. 500 watt, what is the "plus minus" power being supply. i'm sure it's not 100% efficiency! generally, if possible enermax PSU in particular.

regards,

1. AFAIK, Enermax is one of most people would choose. I think if more power needed and greater ampere (A) is provided, won't be a problem. The problem is when the ampere is low, which will cause the PSU to blow or something

2. Check power supplied while running your cpu? I don't think so. Using PSU Calculator, it should show the average watt used by your specific cpu

Don't worry about Enermax so much. Most review says it is one of several good PSU for OC. If it is good for OC, it should be good for normal usage without OC

Just wondering, would it be safe to use a 4pin connector to the 8pin motherboard in long term usage?Currently i own a PSU with 4pin connector but my mobo comes with 8pin.Is it a necessary to change to a 8pin PSU or just plug in the 4pin into the mobo?Just afraid that it might be damaging in long term..

, when comes into overclocking, yes, definitely, you're gonna need 8-pin connector, otherwise, 4-pin into 8-pin should be all right...i'm not sure where's the site, quite long time, but, i saw a pix, using SLI-DR Expert with 20-pin ATX + 4-pin CPU...

I intent to OC with my new board (thats my intention when i get it) but still does not have enough budget yet to get a good PSU (Silverstone in mind).Therefore, i thought of using my current PSU in performing the job for me..What effect it might have if i insist on using the 4pin on 8pin mobo and OC as well?

I might get a SST Zeus 750W. No OP750 in bulk order i'm afraid.

, instability issue will rise up

OP750? AFAIK, BULK only bring OP650 and OP1000, spoke to one of BULKer, kingmaker_20, he said that he will bring in OP750

OP750 @60A

How can we know that we need more power in the current PC setup or the juice from current PSU is already enough?

And at what rate in term of V for the +12V,+5V...are considered as a stable PSU?From PC Wizard, my +12V is running at 11.37V only while the +5V is running at 4.87V..

the rating shouldn't be off +-5 of that rail, which means 12V is around 11.4V, but normally I take 11.6 within the safe zone. This means your PSU is running at it's limit

note : before rushing out to buy a new PSU, you should try another program to check the voltage, no single program gives a accurate reading, the most accurate is using a multitester to check which should be handle by expert only.

I just tested it with PC Wizard currently.But i have tested the PSU before using Smartguardian, showing about 11.6V for the +12V but have a RED sign in the +5V which is showing about 4.3V..Not sure which to trust though as PC Wizard is showing my +5V to be fine..

so what psu should i buy that can support c2d e6600 and 8800gts..budget max rm350 but cheaper is better coz out of budget already..

Silverstone Strider 560W should be all right

Yeah This PSU is a good solution to for that price range. Only drawbacks is its not Modular. Still the juice from it rocks, with 3 years warranty too.

Wanna ask something... in speedfan, it show that my +12V at around 11.13V, in BIOS, it show as 11.8V, so I should consider my PSU is not overloaded or ??? In BIOS, many hardware haven draw much juice from the PSU yet right, so that why it can get 11.8V, am I right? Been searching for higher watt PSU but most of them not Modular... some got modular but too expensive pulak... now dare not to OC my proc yet coz of the PSU...

anyone can recommend me a good 'green' power supply? is this kind of psu can handle high end gaming system? we're talking sli, sound card etc. thanks in advanced.

i'm not into modular type PSU though, modular type PSU not as good as non-modular i must tell you...

that's what we called, voltage fluctuation, the reading may varies from another PSU to another, anywhere from 11.7V ~ 12.7V should be all right... and the best value is, get as close to 12.00V value , no matter on full load or idle...

, i don't get what you mean "green", is it CoolerMaster iGreen? is that what you mean?

Don't trust totally on PSU voltage reading from utility, try a few utility to get the average, not all will give the same reading. Check this out:

This one gives you the amp required.

will check for more PSU...then later when got enough money...will buy new one to replace current Liberty 400W...
