BIOS BootUP Warning Message (Pic) After New graphics card installation

[Brado11]

First off I recently Installed a new graphics card, the EVGA GTX 750 ti (SC edition) and I loved it but shortly after I broke one blade on my CPU fan because it was hitting its plastic case and making an incredibly loud noise.

Then after a few days I noticed a decrease in performance with slower load speeds and applications crashing if I had too many open etc. (on the brightside gaming graphics and FPS went way up =D) until this morning I received this message on bootup.



Now there are 2 issues that come to mind - not having enough power for the new graphics card or the CPU over heating from one fan blade breaking. I would rather not find out my PC is slowly dying from the recent changes because I cannot afford a new one. Are there maybe some fan setting or overheat warnings i can configure in BIOS?

Here is my Power Supply, CPU fan and full specs:







Motherboard: GA-78LMT-S2
CPU: AMD FX 4100 Zambezi (Max TDP 95 W)
Graphics: Nvidia Geforce Gtx 750 ti SC
Ram : DDR3 2x4GB stick (dunno what brand)
Power Supply: [In Image]
Optical Drive: TSSTcorp CDDVDW SH-224BB SATA CdRom Device
Hard Drive: 1TB TOSHIBA DT01ACA100 SATA Disk Device (dont know rpm)
Fans: no idea cooler master i believe
64-bit Win7

First I would replace the CPU fan. Second that card takes 25 watts on a 12v+ rail.
Your psu has dual rails at 14watts each now here is the kicker Two 12v rails at 14 watts does not equal 28 watts on the 12v rail.
If you have two rails at 14 amps each you are pushing the same as 20 watts on a single rail.

So to make your computer last longer and not burn anything up replace the cpu fan and get a single rail PSU with at least 30 amps on the 12v rail. And that is still a bit low to me because you have to figure in the hard drives, fans, ram, dvd drives when in use, and CPU.

The CORSAIR CX series CX430 430W  is cheap and has a single rail at 32 amps.
and the CORSAIR CX series CX500 500W  cost a bit more but carries 38 AMPs on the 12v rail.

I'm rather new to upgrading PC's as a whole so I don't know much about PSU's could you clarify why a 430watt PSU would be better than mine labeled at 500w. Additionally I recently experienced a few crashes could this be connected to running on too low power (I'm guessing that's the case)?

If you look at your PSU specs it has two 12v rails each at 14 amps.  How they do that is if you use just one of the rails it gives you 14 amps. But if you are using both 12v rails it only gives you appx. 20 amps and that graphics card calls for 25 amps on the 12v rail. So with the PSU you have it is under powering your card.

That 430 watt PSU has a single 12v rail at 32 amps so is stronger than your 500 PSU

So a good bet if your CPU temp is fine then I would say it is because you are under powering your system with only 20 amps on the 12v rail.

Alright that does make sense so what I will most likely be doing is buying a more high-end ish PSU like the cx500 you mentioned in order for it to last multiple years and have enough power for further upgrades. If I were to build a new system completely I could still reuse the same PSU from this one right? Meaning that using a PSU in multiple systems is possible. Also are there any requirements for installing a new PSU? They don't differ too much in physical size do they? Thanks so much in advance =D

no size usually isn't a factor unless you are going to a 1200 or larger psu.  Also they make a mini psu for smaller cases and itx boards.
