Was running a 10 year old refurbished Dell, dual core Intel, onboard video card. Started gaming a little, had issues so I bought a lower end video card, ran better but decided it was time to upgrade. So bought a custom built gaming computer. (dual core to 8 core, 4 core recommended for games) Thought it would be lightning fast and super smooth. I have been underwhelmed.

I Bought: iBUYPOWER TD775 Gaming PC - AMD Vishera FX-8320 3.50GHz, 8GB DDR3 Memory, 1TB HDD, DVDRW, 2GB AMD Radeon R7 250, Windows 8.1 64-bit - TD775

Found the radeon R7 card lacking and bought a Nvidea GTX970 on ebay, used. Then the power supply burned out, so I ran to best buy and bought a new, bigger PS, from 500W to 750W. Ran good for a few months. Started to randomly shut down, now runs about 5 mins, fans go on high, then shuts down.

Any chance the card I bought on EBay blew up my computer? I am getting an RMA number from IBUYPOWER to return my computer with the original video card in it. But when they fix it, I don't want to blow it up again by reinstalling the more powerful video card if it is the problem.

Maybe the card I got used on ebay is bad somehow? Does not seem likely, but I only know so much about this all.

What many people do not know is that power supplies are not created equal.

First off, just because a company puts a 500w sticker on the front does not mean any way that there was some regulatory agency that tested and required the unit to be able to output 500w. You can get a really cheap 500w psu from logisys, raidmax, apevia, etc and in reality they will crap out trying to output 300w.

Best buy is a complete joke for PC parts. Out of the 4 or less models of power supply you probably had to choose from, a corsair CX series was likely "top of the line" which any person on here would tell you to stay away from.

If you buy a quality unit from XFX, Seasonic, or EVGA (B2/G2 series) then everything should be good.


FYI, its not likely...

FYI, its not likely the card you got on eBay has a problem but I would buy all new PC parts from a reputable vendor like amazon or newegg. If eBay has a new part for cheaper then amazon/newegg then there is likely something sketchy about it.

Yea you bought a bad PSU, and that Ibuypower system probably had a terrible PSU in it as well. That 500w probably is what did the initial damage, and it just got worse with time. That and you replaced it with another low quality PSU. Nothing new about that system you bought, either, considering FX 8320 is like 3+yrs old. This is why I build my own, and do not buy prebuilts.

Worse, I'm thinking the Best Buy "device" was a PSU-shaped object, like a Dynex or Rocketfish. Possibly good for half their labels, one of those could have easily killed your system. Corsair "CX" isn't good, but it has its protection circuits, and isn't known as a system-killer.

Yes it is a corsair, CX750M, just wanted to get my new computer up and running, had no idea best buy was such poor quality. But why the crappy first PS from IBUYPOWER? I am still learning, and might now be out $650 for computer, ouch. Thinking maybe I should have bought a system with the bigger video card in to start and maybe they would have used a better PS. Does not seem like it should be so touchy. I have done some work on PC's in the past, never a gaming rig. Just wanted to buy a new computer and not have to deal with any issues, FAIL.
I will send it back to IBUY and see what they say for repairs.....

There's a good reason that buying pre-builds is not such a good idea. I started out with an HP Pavilion and started using it as a gaming rig. I began getting into PC gaming at that time. I once tried upgrading to a GTX 680 and a Corsair HX650 PSU; oops, the PSU was not compatible with the motherboard, so I returned both parts and picked up a GTX 660 instead. About a year and a half later, the original PSU blew out when trying to run it after I was having power issues with a Corsair CX600M I bought from Best Buy several months prior. I then bought an XFX 550w PSU, which, to this day, is still solid as a rock. Then Windows 7 (and the Windows 8 upgrade) were crapping out on an added SSD and because Microsoft informed me that the OEM Windows license will not perform as well on the non-original hard drive, I ended up purchasing a new Windows 8.1 license and installing that. Then my old CPU was having heating issues and crapping out because of the poor thermal compound on it. So I upgraded the CPU and motherboard. Now that I have totally converted my previous pre-build into a full-fledged custom build after getting a new case, I have learned a valuable lesson about why it's not good to buy pre-builds as gaming rigs.

Ibuypower does not use quality PSUs. This is a big issue.

Follow up question. Should I send it to IBUY to repair? OR should I buy a GOOD PS and try that first? My feeling is that something is damaged, like MB or something.

BUT without the original PS in it when I send it in, they mighty say my PS caused all the trouble and it is my fault and not cover anything.

Is anything salvageable on this system, or do I wind up building a custom out of a prebuilt like CPUs Master?

And how do I know what is safe to keep and what is not?

I feel unsafe using anything from this computer because I don't know what is damaged. Tempted to toss it all and start over.

(I just wanted to play some games and not mess with computers.... LOL, My 10+ year old Dell/intel dual core is working good at least for email etc.)

While Best Buy does sell cheap, low-quality parts, there are a few exceptions. I purchased my SSD and the old GTX 660 from them as well as a few peripherals and they are actually rather decent components. If you have a Micro Center or Fry's Electronics in your area, they sell many top-quality components. (I even saw a limited edition ASUS Sabertooth Z97 MARK S available at a Micro Center according to the website once.) About the PSU, I strongly recommend getting a good model from Amazon or Newegg. This is the PSU I'm currently using and it fit my old HP well. The non-modular cables can be cumbersome in a smaller case, but it's enough to power up your PC with no problems, especially since you cannot overclock your CPU on a pre-build. Get this PSU and you will not be disappointed.
