Psu - Mb Check

Gents
can anyone let me know if the PSU and the MB below are compatible in a desktop? I have a hungry GPU (GTX 670)

I have someone say it should be fine and another saying its too big and not ATX size. But i had thought these PSU were from the old Alienware desktops?

thank you

 

Not so hungry, a quality 500w will be fine unless you want extreme overclocks. Gold efficiency, new, 7 year warranty Seasonic: https://www.scan.co.uk/products/500...80plus-gold-single-rail-41a-120mm-fan-atx-psu

 

I am rather a noob when it comes to the PSU side of things. i know it has to power stuff but connections and how much other items draw in watts i have no idea. the only thing i know how many watts it takes is the GPU

How much power does a HDD take as i want to add my 500gb hdd to any current build i buy, which has my Steam games on.

I have a 550 ATX model 550AUBA but it only has 1 x 6 pin for gpu. I think its the normal type of PSU. but unsure if it works properly. is there a cheap gadget to buy to see if it works properly? the machine it was put into didnt work properly and i dont know if it was the HDD or psu that was at fault. it would load up then after 5 min go incredibly slow which made me thing it was a HDD issue.

i guess once i can understand what power the items in the rig consumes i can better judge if it has room to fit my gpu in it or if a psu upgrade is needed. Shame that many used i7s on ebay are 350 watts.

Thank you

 

3.5" HDDs peak at ~15w on starting, probably 9-12w in active use.

A PSU with a single 6-pin for GPU isn't likely to be a real 550w, more like a poor quality/old design 35ow.

There are PSU testers but they're basic, no real-world load testing ability.

 

this was the PSU i spoke off

but like i say didnt come with 2 x 6 pin
is it a bad quality PSU?

I find it annoying that most used desktops on ebay do not mention anything about the PSU or MB. the model types of desktops are not known to me so i dont know if any would be suited to adding a better PSU that would be supported by the MB and thus my GPU.

Would be happy for just a i7 2600 desktop with a MB that allows my GTX670 and a normal 550 PSU. The i7 2600 would double my CPU spec going by userbenchmark

Thank you

 

It's an unknown brand to me, I wouldn't trust or recommend it. If you have to go cheap, maybe this would be okay, cheaper, lesser brands I wouldn't trust.
