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?

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!

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?

Thinking of going quad-core once Intel drops the CPU prices on July 22nd.

I'm using enermax liberty 500watts.

Do you think it would be adequate to run a q6600 + single 8800 GTX?

If so, would I have enough wattage to OC the rig?

Ok. Thx for the advice!

Wahliao! Why a 2k watt PSU?

One thing I've learned about PSU is that it is better to get a slightly higher wattage than your requirement. If you need a higher wattage PSU next time, just sell the current one and buy a new and better featured one!!!

Imagine running full load 24/7. Your electric bill charges will go through the roof!

So guys, I'm getting my Q6600 probably tomorrow.....

Think my Enermax Liberty 500w can handle it?

I think I have to limit my OC on both my GC and the proc...... probably go 3.2Ghz only for the Q6600....

No la, me average OCer only..... I hope to keep my Enermax, don't want to spend more money......

Haiyooo... don't want to spend some more money.....

Now testing my Q6600....

Can take a look at my PSU guide... got some tips on buying a PSU too.....

The minimum requirement of the 8800GT is 400w with 26A on the 12v rail.

You PSU has dual rails and will probably have a total of less than 26A on the 12v rails...... You can't add 10A + 15A to become 26A. Look at your PSU's specification. It should tell what your amperage is on the 12v rail in total....

Anyway, your PSU doesn't meet the requirement on both aspects.... Better get a better one....

The 550w should be enough.... from his thread, he said it was truepower, meaning that it should be able to supply a stable continuous power at that range.... however, at that price, not too sure about the quality...

Look at my sig.... my rig is overclocked, and I'm using an Enermax Liberty 500w (truepower too).... so the 550w should be adequate for you rig....

Not too sure whether your PSU is adequate or not..... why not try using a PSU calculator to calculate....

Anyway, take a look at these links:

ST85ZF is a tier 1 psu, which is definitely the best tier to go for.... but cost more...

ST85F seems to be a tier 3 psu....

I'm also a noob when it comes to PSU....

Can read up on my PSU guide.... got some basics there....

You should buy base on your needs and the wattage requirements of your rig.

I'm using a gigabyte Odin GT 550w and it is not a bad PSU... you can get the gigabyte Odin pro 550w for less than RM400....

Try to go for tier 1 or tier 2 PSUs.....

Take a look at my guide on the PSU... There are tips on how to buy a PSU...

A good 500-550w PSU is enough for your CURRENT rig.....

ATI recommends at least a 600W PSU......

Last time, my 2nd rig had almost the same specs as your rig, with a Nvidia 8400GS Graphic card. It was only using a 350w PSU without any problems....

For the ATI 4850, the recommended wattage is at least a 450w PSU.... a bit higher would be better, as you are OCing your rig too

Modular design produces less clutter in the casing, a neater appearance and less interference with airflow as you can limit the amount of cables attached to the PSU. Due to the electrical resistance at the connectors, enthusiast prefer not to use it.

Pros
- Less clutter in casing
- Neater appearance (especially for those who do casing designs)
- Less interference with airflow inside the casing

Cons
- Electrical resistance at the connectors
- Connectors may degrade or loosen if you frequent unplug/plug them
- Reduced airflow inside the PSU itself due to additional components
- Slightly more expensive due to extra connectors and special cables

Can read more on the basics of PSU in my PSU guide.
