First off, No.
To expand on that, let's weigh the pros and cons of attempting to use a cheap, crap, PSU on a decently high draw rig (or any rig, really).
Pros:
Doesn't cost much.
You can run right now.
Cons:
May explode due to horrible quality control.
If it explodes, may catch fire, burn house.
If it explodes, may destroy everything plugged into it.
Probably won't actually be able to power the rig, anyway.
May explode due to not having enough power.
You spent $200 on a CPU, $200ish on a SSD, some hundredish on a GPU, and you're going to trust this to a PSU that may or may not be high enough quality to function as a paperweight?
That's like buying a Ferrari and running it on gas and oil you bought from a pikey with a bunch of buckets.
Don't do it.
