Fried Psu but can't go into bios with other psu.

SmexyGaming · Jul 25, 2017

I just fried my psu. I was playing bf1 all night at 1440p 60fps. Smelled something burnt and pc randomly shut off. Had it for 3 years. Put in my old 300w psu pc turns on however I cant connect the 8 pin to gpu since I don't have 1 on that psu. Tried going into bios but can't. Is it bc my gpu doesn't have its 8 pin?

What CPU do you have?

And yes, if your GPU doesn't have any power going into it it cannot boot to BIOS.

SmexyGaming · Jul 25, 2017

My cpu is the i7 2600k I haven't overclocked yet and not planning to btw. So turning on the pc everything sounds normal. The fans are spinning as much as they would spin if I was loging into windows so cpu should be fine. Also gpu leds shine but fans don't spin bc of no 8 pin. Thoughts?

SmexyGaming · Jul 25, 2017

If the cpu fried technically the fans would ramp up uncontrollably and it wouldn't sound normal like it is right? A bit worried

okcnaline · Jul 25, 2017

Remove the GPU and boot the computer off the CPU (it has integrated GPU) to verify whether the motherboard, RAM, and CPU was fried. 300W PSUs can only handle a GPU that only uses power from the motherboard (aka no PCI-e 6-pin or 8-pin).

Okay I just did that and logged into the bios thank god everything looks fine

SmexyGaming · Jul 25, 2017

The psu I had was 550w and my system used about 500w when playing games. Do you think a higher watt psu will be better? Also have you heard of the company nitrox for psu? Are they any good? A retail store has them thats y I am asking.

In the 3 years you've had your system, did you bother to put any fresh TIM on your CPU or GPU? It sounds like your PSU is working, because you said you're still getting power to your fans & I assume, your basic case lights. Does your system make any beeps when you turn it on, or what do the numbers say on the diagnostic led say, if anything? It sounds like you fried your gpu or cpu, rather than your psu. Or.... otoh, it could be your PSU as well, but just part of it. Among other possibilities.

SmexyGaming · Jul 25, 2017

Important question but try to answer the previous one also. I just tried to exit the bios and log into windows but it's not letting me. It's just staying in the bios. Why?

SmexyGaming · Jul 25, 2017

Oh sorry didn't specify nothing turns on with the 550w psu. Everything turns on with the 300w psu

Virtual_Singularity · Jul 25, 2017

Most likely because either your cpu or gpu is hosed, sadly.

SmexyGaming · Jul 25, 2017

What? But everything is detected in the bios and temp is 37 degrees. If it was dead it wouldn't go in the bios

Virtual_Singularity · Jul 25, 2017

It is possible, depending on your CPU settings & system. Am assuming you mean your CPU temp? You smelled something burning, you thought it came from your PSU, ya? Check the TIM on your CPU just to be on the safe side, regardless what your bios says. Also, it'd be very helpful if you got up close & personal with whatever component you smelled burning. Use those olfactory senses, where is it localized? Your PSU?

SmexyGaming · Jul 25, 2017

Update. Turns out it boots cpu is just fine. I forgot to plug in the sata hdd cable bc the other 1 from the other psu was plugged in. So only thing to test for now is gpu. How can I do this if I don't have an 8 pin? Ty

SmexyGaming · Jul 25, 2017

I was panicking a lot there but everything's fine in the end. Rookie mistake. Also the part that smelled burnt was in fact the psu. Thank god it didn't destroy my componets with it

Chicano · Jul 25, 2017

If a Hardware Issue: If you can access the BIOS the CPU is ok, the GPU needs another PSU with better wattage and the 8 pin connector.

If a Windows (software) issue: Windows not loading has nothing to do with the CPU or GPU... it can be a HDD or Windows issue depending on how far after the BIOS post it gets.

a) An HDD or MBR/GPT issue may display a "OS not found message" or "bootable drive not found"
b) a Windows issue can display a boot error message or it may start loading Windows and return to the BIOS.

Ignore this: I see I answered to late... page refresh issue.

SmexyGaming · Jul 25, 2017

I see I guess I will hae to buy a new psu and see. So I want to get it today from a store rather than ordering online. Store has some psu from Nitrox. Planning to buy a 650w one but is it a trustworth brand. Price is 50 euro don't know how much that is in pounds or us dollars.

okcnaline · Jul 25, 2017

SmexyGaming :

Go to a local store to test the GPU now.

Chicano · Jul 25, 2017

Check the PSU brand and model you want to buy against this Tier list, to know it's Tier level... the lower the tier number the better.. and for a low budget, I wouldn't recommend going over Tier 3.

SmexyGaming · Jul 25, 2017

Can't go to the store at the moment bc it's not open and I will be busy througout the morning so going to update you in the afternoon or in a hfew hours bc of the time zones. I doubt the gpu is dead since it's at the top of the pcie slots far away from the psu and I could not smell anything burnt on it and it was running bf1 perfect before the big crash. If it is though I still have its warranty which is great

SmexyGaming · Jul 25, 2017

Ok so in terms of the psu this is it here. Im not too familiar with psu specs I just buy what someone reccomends. Could you do some research and tell me if its good thank you. Btw it only has molex but it's fine since I have a molex to 8 pin cable https://bionic.com.cy/products/nitrox-atx-sl-650-650w-power-supply

Chicano · Jul 25, 2017

I havent found information on the Nitrox brand quality but will keep looking... meanwhile check Rogue Leader's comments (all of them) on the Nitrox PSU brand...

http://www.tomshardware.com/answers/id-2806999/psu-good.html

More comments on rating the Nitrox brand
http://www.tomshardware.com/answers/id-2762968/nitrox-power-supplies-good.html

The problem is it's apparently not included in any Tier list which means the tier rating number must be high (for low quality).

SmexyGaming · Jul 25, 2017

Don't think Nitrox is a good brand found a negative forum on them. Went to a different store site and found this coolermaster psu. Is it trustworthy? http://www.eshopcy.com.cy/psu-coolermaster-elite-series-600w-p-PER.814997

DSzymborski · Jul 25, 2017

65% advertised efficiency? A "650W" PSU with a single 6+2 connector? Passive PFC in freaking 2017? That PSU looks like literal garbage. If someone broke into my house and tried to install that PSU in my PC - admittedly a highly unusual scenario -- I'd give them the €49.99 to *not* install it.

DSzymborski · Jul 25, 2017

SmexyGaming :

There are some good Cooler Masters, but those tend to be on the high-end. Usually you can find Corsair CXMs (you want teh black and white label, not the green one) or Seasonic 520s fairly widespread on the budget end. Admittedly, I'm not familiar with the availability of PSUs in Cyprus, sadly.

Fried Psu but can't go into bios with other psu.
