Geforce GTX 650ti - 20A and a 400W PSU minimum

Geforce GTX 650ti Boost - 24A and a 450W PSU minimum

Corsair GS600W 600 Watts will be a better choice than CX series.

If you have already purchased it then nothing can be done. I wouldn't trust CM's Thunder, its a bad unit.

You wont find any good reviews on any reputable site, cause its a cheaply made PSU, cant trust for a longer run, and the wattage are overrated than they actually are. Its not even a TIER 5 quality PSU, let alone 1,2,3,4 TIER. Capacitors are Chinese or Taiwanese rated at 40C which will eventually fail after sometime.

I looked up the 500 watt thunder and there are two models. One OEM'd by Enhance, the other by Channel Well. While it guarantees nothing, it's a good sign that quality OEM's were used. It wouldn't be my first choice either, but Im sure its serviceable.

Thank you very much for the response.

So you mean , the main issue with CM thunder 500w is about temperature?

Usually i wont play games more than 2 hours continuously, also my room temperature is maintained around 20 degree Celsius always.

Actually i bothered about the system performance.
CM thunder 500w is enough for producing max. performance of my graphics card, ram and processor?

Lone wolfs concern, correct me wolf if im mistaken, is that many PSU manufacturers use poor quality components and overrate the power output by testing at a lower ambient temperature. In some cases, they just lie by labeling a PSU as a 500 watt model when its only a 200w or 300w unit. This stuff does happen and he is right to be concerned. The lack of available reviews prevents us from putting that issue to rest or perhaps confirming it in this instance.

Cooler masters reputation is somewhat middling in the PSU market. They have a fair number of questionable units in their past. Most memorably, a 400w model they labeled as a 600w unit a few years back. However, they don't make their own PSU's. The hire other companies to manufacture them and usually base it on the designs of the contracted OEM.

For the Thunder 500w, they list two models. One is OEM'd by Enhance, the other by Channel Well. Both OEM are manufacturers of high quality PSU's. That bodes well for the Thunder being a quality unit. But there are no guarantees without an examination of the unit. Coolermaster can tell the OEM to use older designs or cheap components to save money and they could also lie or exaggerate on the label..

@FALC0N :- Yes you are right, that is my only concern. PSU is a vital component, all the components will depend on clean power supply from PSU, and with CM's Thunder there is no guarantee of that. This could damage the other components.

@ OP :- I can only suggest you, do as you like to do, but again I am repeating CM's Thunder is nor a good unit. And my concern is not with only the temps, but also clean power supply, and the wattage it can deliver when in full load.

I would not go so far as to say its a bad unit. Enhance and Channel Well manufacture very few bad units. If anything, cooler master might have over-rated it on the label.
