My old PSU just stopped working and i had to purchase a new one. It is arriving in 15 days but I want to play meanwhile.

I have a new 500W really cheap OEM PSU, that cost like 20 usd new. How crazy is to use it while my new PSU is coming? Can it damage anything? I have used those on old cheap PCs and they never burn anything but they stop working on 2-3 years

The PSU is this one:
http://www.newegg.com/Product/Product.aspx?Item=N82E16817165024

My build:
i7 2600k, Mobo Intel Dq77cp, 8 GB Ram DDR3 Hyper X and XFX RX480 8GB GTR

Obviously without any OC.

personally i'd suggest that was a 240W PSU as that's what you'll get out of the 12V rail.

So a 2600k is a 95W processor, the 480 is between 160W and 300W at full load, so in total you're asking that PSU to supply between 255W and 395W, 90% of which will come from the 12V rail.

I wouldn't even use it as a doorstop.

ok... I never herd of that brand you should of got a logisys it 21 dollar for 550w on amazon and I know it will last long and yes if one of the rails either 12 or 5 volt stand by get out of wack it could fry the chip set graphics card or cpu but it a hit and miss some are good some are bad.

Yeah but I already own that one and I did purchase a Tier 1 but its coming in 7-14 days (I am from Mexico and the free Amazon shipping takes a while)

My question its about if it would be dangerous to use that? What about using it without my GPU?

EDIT: You just edited your answer when i replied xd

Not dangerous unless you going over the rated watt most cheap power supply can't even reach rate the one you bought is a 500w and it probably max watt out put would be 480 or lower.... since it cheap hopefully not lower than 480w. and if the one you bought doesn't have the pin connector 6 or 8 pin for the 480 then I would worry about it. But honestly stick with the logisys it safer in my opion.

That PSU should be rated for ~250W not 500. It probably has none of protections built into it.
Using it in high performance gaming PC would:
1. kill the PSU;
2. most likely kill something else in your PC also.

I think that the overrating on that PSU is a lot more than 20W, and on cheap PSU's danger can occur from 0 to 100%, i'd just turn the machine off and wait for the one that is being shipped.
