Shortage power supply

[trapizi]

Hi guys, so my friend is building a new pc and he notices that whenever he remove his graphic card, the CPU fan runs faster than normal. Is it because of insufficient power from the PSU?

What is the specs?

What is the PSU?

My thought would be that the fan needs to run faster since with the graphics removed the CPU is in charge of everything thus getting hotter thus needing more cooling. This is all a theory but typically if the PSU is not powerful enough there are more obvious signs. Just wondering whats the specs of the PC.

No, probably he's a CPU with iGPU so that means more heat output when using the iGPU

The PSU needs to go, but 450W is more than enough for that PC.

Replace the PSU with an EVGA B2, G2, GS, GQ, Anything from Seasonic or XFX (Excluding the XT), Corsair Gray Label CX, RMi, RMx, HXi or Antec High Current Series.

I wouldn't be surprised if that PSU was dying, it's a really shitty model anyway. Cheap alternatives would be the XFX TS 430W, the Seasonic S12ii 430W or the CX450M. The wattage is fine though.

The VS450 doesn't look too bad to me.

The fact that the entire VS series is actually terrible. Chieftec has a unit based on the same platform...

Would you please proof your "fact", cause otherwise I will just call bs.

EDIT: 
Not a great design, but you can see some performance figures based on the Cheiftec unit of the same design: http://translate.googleusercontent.com/translate_c?hl=es&rurl=translate.google.com&sl=auto&tl=en&twu=1&u=http://www.easycom.com.ua/power/chieftec_gpa-450s/%3Flang%3Dru&usg=ALkJrhiIF2_kMsMDhIfm6A1RDs7BwENmVw

Some of the secondary side capacitors are made by Aishi, but most are from CapXon – a brand renowned for poor quality capacitors. Even in an entry level product, it surprises me that Corsair would be brave enough to use them, as I have had to fix plenty of devices with failed CapXon capacitors which weren’t very old. Even Teapo and OST capacitors are generally considered to be more reliable than CapXon.

 

(The review you provided)

The 12V regulation is not something to be proud of, that said the 5V and 3.3V are not that bad (Look at review to see that, they are huge images and another 2 isn't a nice thing to load) http://translate.google.com/translate?u=http://www.playwares.com/xe/index.php%3Fmid%3Dpower_hdd%26document_srl%3D29556352

I don't know the platform. I have seen it referred to as the CWT GPM, GPK and GPA, they are probably very similar and are just minor revisions.
