I noticed recently that my fan on my MSI K7n2 MoBo is not spinning. This is resulting in higher than normal temps. Also, I just upgraded to a BFG nVidia 7800 GS which needed a higher PSU rating (I had only a 380W, I needed min of 400W). So I ordered an Ultra X-Connect 500W (the pretty green one).

Well hell, the PSU isn't lighting up so much anymore and the computer keeps restarting randomly!!

I think the mobo is overheating, but now (just now!!) I realize the psu isn't half as bright.

I don't know what's happening and I'm scared!

Well for the restarting problem it could still be your power supply as i know that the 7800gs needs 20amps on 12v+ rail or something. You must make sure you psu complys with this.

What fan do you mean? the chipset or the cpu?If its the chipset it shouldnt be to much of a problem.But if its the cpu fan your cpu is overheating causing the shutdown"s.Let us no i have a few fans and a few old heatsinks laying around maybe i can help you out

Then after fixing these if you still have problems then i would rma that psu but frist lets see about the fan's

ASRock Z97 Extreme 4 / i7 4790K / Corsair H80i / 4x4GB Crucial Ballistix Smart Tracer DDR3 1600 / 1TB Western Digital Caviar Black / 240GB Mushkin Chronos Deluxe SSD / 2x Evga GTX 670 FTW 2GB in SLI / Sound Blaster Recon3D Fatal1ty / Corsair HX1000w

It's the chipset fan on the mobo. not the cpu fan. cpu works.

Last night I turned on Oblivion and the computer shut down adn wouldn't turn on when I hit the button. I had to interrupt the circuit and then reestablish it with the psu switch. When I tried to power on it beeped at me like it's never beeped before and I thought my cpu melted. well it didn't and I used the switch to turn it back on and here I am. I have "everest" running and my board is at 40 C (cpu) and 27 C mobo I think. This is only because I have my computer opened up and a huge box fan blowing directly at the mobo.

I really don't think it's a power issue because like I said, I just replaced my 380W (only 18A at 20V) with a 500W xconnect (a burly 30A at 20V).

Am I going to fry my mobo!?!?!

Help! I don't have the money for a new comp and this is my JOB!! (webdesigner)

Should I just put my old PSU back in??

Sean. My mb temp is usualy 32-38c, and my cpu is usualy 25-30c. I think your temps are normal to medium. I dont know about your threshholds on either though. More case fans would help. And a new chipset fan also would help.

About restarting. DId it just start doing this when you put the new psu in?? It could be a bad psu. And is it one where you plug in the cables of wich you need etc, if so make shure you have all the cables very much plugged in. Even though it sounds like a good brand doesnt mean you are the 5% tile group that gets a punked product =(. I have pretty much the same psu as you and it works awsome for me =). Ive heard complaints on psu that are moduler though.

Also for the extra cable pluged into your video card from your psu. Make shure its a seperate cable directly pluged in, nothing else plugged in from that cable.

Sounds stupid or dumb, but Make shure everything looks right inside your computer, plugged in, pushed down etc. I had a cpu overheating cause my heatsink fan wasnt getting a solid fit cause of the plastic retaining things that held my heatsink to the cpu thing wasnt secure. I had to push the plastic pins down threw the mb to fix the issue =(. Ahh I spent hours and hours with this and went for like a whole 8 months with this issue and fauled to check something aslittle as that. My temps showed they were all good but thats cause there was a sensor on the bottom of the heatsink giving off bad temps cause it wasnt secure to the cpu =(.

Dont know about anything else though, im not a computer guru just a moderate novice.

About my spelling, If you say anything about it im gonna hunt your nerdy english aniel retentive arrrssse down and beat the elcrapo right out of you!!!!

Sean if you are worried about system temp the Thermalright NB1 Chipset Heatsink should do the trick:

Ok, the fan is still broken, and I'll totally take you up on that offer of a free fan if you're still offering! I opened my case and stuck a big box fan against the side so it's pretty cool now, about 40/50C... gets to about 58 when I'm playing Oblivion.

About the PSU, I got a new one, it was defective. This one is good.

If your'e looking for PSUs, get Ultra.
