Recently New Built Computer

[Guest]

Ok, so I ordered all the parts I needed from SCAN, and took the time to build myself my 1st computer ^^

The building went fine, but for some reason, I have random shutdowns.

At first I thought, something is overheating, but after testing and monitoring both the gpu and cpu and finding no errors, I am thinking otherwise.

My rig is this.

Motherboard: Gigabyte GA-790FXTA-UD5
CPU: AMD Phenom II X6 1090T Processor 3.2ghz
Ram: Corsair 4gb
GPU: ATI Radeon HD 5770
HDD: 640gb seagate 7200rpm SATA III
PSU: Powercool PC-950AUBA-B 950w
OS: Windows 7 Ultimate (legit)
Case: ThermalTake one, has 1 large 220mm fan at the top(exhaust) and 2 120mm fans front and back, intake

I really don't know what is causing the issue, If i have missed anything please tell me and i will add it.

Thanks

I am suspecting you PSU as the culprit in this case as its not of a reputable quality brand like corsair, antec, xfx etc etc.

That's what I am thinking, are there any tests i can do to be sure of this?

I don't want to throw away money on a psu if its not the problem ^^

 

[Guest]

just ran some tests

CPU idles at 30C and under load averages at 40-45C
GPU idles at 35-40C(depends how cold my room is) under load can be from 50-60C

PC shutdown last night, randomly, after checking the logs, I concluded that neither my GPU or my CPU overheated.

Can anyone help me?

Its not your CPU or GPU buddy, its i would say 99% certainty your PSU, have you not got another old PSU in the house or one you could borrow that you know defo works and can use it to test, otherwise RMA the PSU and buy yourself a decent 650watt unit which will easily meet your power needs.

Sorry i may sound like a noob here lol, but what is RMA?

Also I bought it a while back so will that affect it.

And thirdly my other psu is only 400w so i dont think it will power anything lol

A 5770 only needs about 90 watts. Unless your 400 watt PSU is a total piece of crap, it should power your system long enough to test it.

Would it not be more effective me spending the extra £20 and going for say an 850w cosair rather than a 650w?
