Is this power supply good enough for my PC??

post #1 of 43
Thread Starter 
Hi, there is a possibility I am buying the following psu. The PC I will be using is in my signature.

http://www.thermaltakeusa.com/Product.aspx?C=1247&ID=1539#Tab0

The downside of the psu is it was released about 5 years ago.

Note that, My PC is quite modest in terms of power consumption--from mobo to everything... And though I know power on +12V rails is much more important than the total power of the psu, different online power supply calculators recommend around 330 watt total for my PC(Considering peak load and cpu utilization 100% and capacitor aging 15%).

My cpu TDP is 65 watt and non-overclockable. And the gpu HD 7850 official TDP is130 watt(needs one 6-pin connector). Obviously the gpu will use more than that when i overclock and overvolt, which I intend to...

And with my current psu(total 264 watt (continuous) on two +12V rails), I have stress tested both cpu and gpu(not-overclocked) with 100% load simultaneously for more than 70 minutes without any problem.

However, I'm planning to buy a new psu because my current psu has no built-in 6-pin connector and I had to use dual molex to 6-pin converter to power the gpu. And while overclocking and overvolting(increasing about 0.02 volt) the gpu, the two yellow wires of the dual molex got burned(at the molex end) and fortunately the gpu hasn't been damaged. I, however, for several reasons think this happened not because the psu was unable to supply enough power to the gpu, but because of the poor quality of the molex to 6-pin converter or its wire. But I'm of course not sure.

So, I don't wanna take any risk and want to buy a psu that has built-in 6-pin connector and provides at least around 350 watt in +12V rails and will not bottleneck my gpu overclocking to any extent due to limitation of power in +12V rails .

So should the psu be good enough for these requirements?

i would suggest this much better power supply for a much lower cost:

I'm buying the psu second-hand and mainly so I barely have any luxury in terms of choice. That psu is available right now. I either buy it or not.
So, thanks for the recommendation. But direct answer will be much more helpful.

Don't, is just as bad as your current one.

Where are you buying from and what is your budget?


ps. Your signature system draws ~200W at full load

I live in Bangladesh and am not shopping online now. My budget will be around 40$ to 45$ max but as I said it will be highly unlikely that what u recommend is available-- at least now.

Why? And which of the factors do you consider when you judge the quality of a power supply? Knowing the specific answer will help me a lot.

200 watt total or on +12V rail?

I can't exactly remember the details of that unit but I believe it's a CWT GPA or GPB, as you can see (from the pics and the power distribution table) it's a severely overrated passive PFC unit.... basically it's trash.

Complete system draw (you have a very modest system in terms of power draw).

Check this thread, buy anything you can afford from that list... even the lowest output unit there would be plenty.

@Original Sin, I don't quite understand what u mean by 'u can't remember'. I've given the link of the discussed psu.

And thanks for that list, probably be helpful later.

And I don't know what CWT GPA GPB mean.. Would be better if somebody enlightens regarding this and the factors which determine the quality of a power supply unit as I asked...

listen, if you could get a ton of potatoe batteries, they would deliver more reliable power than that power supply

By CWT, Sin was talking about the true manufacturer of that PSU. GPA/GPB are the series, and yes, it is a terrible power supply.

Factors influencing PSU quality are, Build quality(components used etc), voltage regulation (how close to intended volts the unit outputs under load), noise and ripple suppression (how clean the power is), efficiency, and actual wattage output at max temperature. Those are the real specs for good power supplies. Unless I miss my guess, None of that information means anything to you. So stick to the list that Sin linked you or look up reviews on jonnyguru, to see what will work for you.

DO NOT use the power supply that you linked, it is a steaming pile of useless garbage. thumb.gif
