Is my XFX 750w not enough for my computer or is it going bad.

post #1 of 20
Thread Starter 
Right now I am running the computer in my sig. Recently my computer has been hanging at the starting windows and would need to system repair in order for it to boot. Some of the times even when it does get repaired it still hangs. Sometimes restarting it a couple times without the repair would load and not hang. I did memtest with each stick and it came up with no errors, used furmark for the gpus and theres nothing wrong with them. I dont think anything is overheating. My cpu is at 45-50 on load and gpu at 75-80 during furmark. Nothing on my system is overclocked. I have 4 sticks of 4gb ram running at 1333 mhz @ 1.5 v . When I take out one gpu everything works. When i check the psu calculators it says that 650 w should be enough.

Do i need a bigger psu or is my current one just going bad?

A good 750W like the one you have is indeed more than enough.
Your issue does not sound like it has anything to do with your PSU. If it were, you'd be more likely to have problems under load than when booting Windows, when load is low.

Ive tried reformatting my ssd and reinstalling windows a couple times already and it still does it. Also now it freezes sometimes when I play bf3. I just thought it might have been the psu since when I take out a gpu everything is ok. Any tips on finding the exact problem?. Thanks for your help.

When I had 2x 5870's I would get lockups due to heat even tho the GPU's werent showing super high tempatures. I don't know if it was related to some sudden spike in temp or tempature on a component that wasnt being measured... like perhaps VRM. Anyway, I solved it by making a custom fan profile using MSI afterburner (had it ramp up faster), and adding a case side-wall 120mm fan pointed at the GPU's.

Just some ideas for you to try.

I had a similar problem after installing a new power supply. It would hang at loading Windows. It turned out that I didn't have a Sata cable plugged in fully. I found this out by hitting the tab key during the boot process. The message was something like looking for device on Sata port 3 or something. My motherboard is an Asus Rampage III Formula. To route the cables, I decided to just strip everything out and build it from the ground up. The Sata cable in question wasn't fully seated and went to my DVD writer. I hope this helps thumb.gif

I guess ill doubke check the vrm temps on my 5870s when I get home.

I dont think its the sata cables because I just transferred to this case like a week ago and everything connected is working, but ill double check that too when i get back.

Check your SSD / HDD for errors (chkdsk). It doesn't seem like a PSU issue.

I checked my ssd which has the os on it but I never checked the drive I use as storage. I guess I will check that one too.

Thank you all for your input.

If it happens during boot I would point that to an HDD/SSD issue - maybe a bad sector? Would start by running chkdsk and go from there. Does NOT sound like PSU issue....

Disable crossfire and report back.

If you really think you're drawing too much power (which I can tell you that you certainly aren't!) pick up a Kill-A-Watt from ThinkGeek and measure what you're pulling from the wall. with my 1090t system that I had previously with 2 5870s with heavy overclocks on the CPU and GPUs I would pull around 210 watts at idle and up into the 5-600 range gaming.

I believe you are having video card issues - try swapping out your crossfire bridge.
