Is it reliable and stable? Is it a good brand (gigabyte) as Coolermaster ones?

Should be fine, as long as its not a cap ayam brand PSU.

For just the processor any PSU can be used. Usually we determine the overall power, especially for the graphics card.

What software do you use for reading the voltages?

You should know that the HD3870 requires a true power 400W PSU with 30A on the +12V rail(s). Certainly not for cap ayam PSUs like PowerLogic.

At least (minimum) 650W, the higher the better especially for a high end system. For high end system 750W would be recommended.

Those power efficiency figures, 80% is the maximum output of the PSU for the whole system. For example let's say the PSU can supply 800W maximum, that means the total power the PSU will pull from the mains will be 1000W. That 200W is wasted inside the PSU for the conversion (from AC to DC). This the higher the efficiency, the less is wasted.

That is GigaByte Superb, not GigaByte Odin Pro... otherwise it wouldn't be that cheap. The real power of that PSU is 610W only. You can check the specifications here

Tagan is rather famous too, and also more expensive than others when comparing price and wattage.

Should be fine as the X1650 Pro doesn't use a lot of power. However for peace of mind, maybe its time to invest on a true power PSU.

The 9600GSO has about the same power requirements as 9600GT. The AcBel E2 Power 510W (real power 450W) should be sufficient.

Try looking at Vantec ION2+ 500W.

Its fine, real power around 500W to 550W.. What graphics card are you going to use?

get a gigabyte superb 720W.. the price is around ur budget.. but the ACbel is good enough

Yups. Do note that those PSUs use peak power rating (peak wattage), not actual/real power rating (true wattage). The GigaByte Superb 720W real power is only 610W.

i think tats why he recommended me Tagan thanks for ur ans

but some users said, it's not true power..

@lex

Thanks for the info.

mm, do Odin PRO 550w have true power?

I've did some research and found out Gigabyte Superb 720W comes with 3 12v rails and is APFC with 80% efficiency for the price of RM 260... which is a bargain than purchasing CoolerMaster Extreme Power 650W which is RM 290 and no PFC...

So is it gigabyte superb 720w worth to buy if i intend to use GTX260 SP216.

I'm currently using rather old Acbel 400W with PFC. very lasting i would say...

AFAIK, GB Superb series is not 80% certified Are you sure you're not refering to Odin series?

If it's a 80% certified PSU at such a low price yet higher wattage, other companies can close shop

This is the link >>> http://www.gigabyte.com.tw/Products/PowerS...ductName=Superb 720

as gigabyte claim its 80% efficiency.
i guess its a vr good budget PSU tho.

Thx bro lex and mantiz125 for the enlightenment ! Gonna get E2 510w this weekend then.

I use OCCT and Everest Ultimate Trial version software.both showed around 3V for the 12V reading.i dont know why lol.

Guys im using Gigabyte odin 550w, i was wondering does this psu consumes as much energy as half of an aircond? The electric bill will be quite high?
Im using, intel QX6800 , 9800GTX+ 1GB, 1 optical drive and 1 hdd. Thats all.

electrical consumption is depend on ur rig. not PSU. PSU only give power to ur rig. more power ur rig, more pwer PSU is needed thus more power is used.

The more efficient your PSU, the more electricity you save = less electricity bill lor... Thats why dont buy chapalang PSU lor...

Cap ayam PSU = draw excessive power to juice your rig
True power PSU = draw optimum power to juice your rig

Example:

Cap ayam PSU draws 500W of energy to power up 250W of actual usage
True Power PSU draws just enough wattage to power the rig

haha. i'm talking bout true power PSU. (80+ certifid).
so it's depend on ur rig.

Thanks alot bro..9800GTX+ consumes quite alot of power ?
