Power adapters questions/problems

[Shadee13]

Hi!

My friend got a new GPU, to be more specific it's an ASUS GTX 760.

I'm making it for him but I have one question if it's safe, because in my opinion it's only a temporary solution.

So his PSU is just some "rubbish" for 20€ and it has only one 6-pin PCI-E and the card needs one 8-pin (2 6-pin with adapter). And I got a 2 MOLEX to 6-pin PCI-E adapter. So it would be like:

1 6-pin (from PSU) to "2 6-pin to 8-pin"

and 2 MOLEX to 6-pin and that 6-pin to the 8-pin adapter

And I'm asking that is it safe that the power is going through 2 adapters... Because with a cheap PSU it's not even safe to have it connected regularly, not through 2 adapters.

And please don't post answers like "Buy this Corsair PSU now for just XX€ on newegg." Because it's not my PC, and I don't live in USA/UK to buy from those places.

And yes, I told him that the best would be a new PSU, maybe he will buy a new one next month. (And I will select it for him because he would buy some rubbish again)

And a new monitor too because he's got an old monitor which is a "VGA" one. (Yeah, I don't know how do you call it in English)

So yes, that was very stupid from him because he bought a 230€ GPU while he's got a very old monitor and a very cheap PSU. (Don't blame ME because of it!)

P.S.: Sorry for my bad English.

P.P.S.: Sorry if I was too offensive in this post , because I have written this to "Tom's Hardware" and that forum is full of people who never answer to your question just tell you to buy a new one... I just copied this from there and didn't have time to edit it.

I wouldn't hook up my shiny new graphics card to a £20 psu...

as long as the power is above 600 wats i think you should be fine i have run two 770 off of a 650

How many watts is the PSU?

If it is at least 500W then it will be fine, but try to get a reliable one ASAP.

You never know when those adapters are going to fail or melt.

If the PSU is less than 500W you might burn it out, or even worse, burn out your motherboard wit a power surge.

It is risky, but the adapters should work as a temporary solution

Thanks for the reply, well this PSU Calculator ( http://extreme.outervision.com/psucalculatorlite.jsp ) told me that the recommended wattage for the PSU is 366 and minimum 316. His psu is a 400W one, so technically it shold be enough, but I know too that cheap PSU shouldn't run on the max. So, what do you say? I told him that it can burn out your whole PC but he doesn't seem to be worried... I will tell him that if you really so much want this card in your PC today, then have it, but it will be very risky.

And talking about a new PSU should that be an Enermax or Seasonic? (trust both of them because I've got an Enermax and my brother's got a Seasonic, and I know that a lot of PSUs are based on Seasonic)

I found this:

Seasonic: SEASONIC 500W SS-500ET T3

Enermax: Enermax NAXN ENP500AGT 500W 

OR Enermax NAXN 82+ ADV ETL450AWT 450W

What do you say? Should I refuse to do it for him? (But probably then some very smart repairman would put it there for him just for 50 bucks)

Should I force him to buy a new PSU?

I think it will be fine if he uses the adapters for now, but let him know he should get a seasonic PSU asap.

OK, but here is just some information about his PSU:

His PSU is a Maxcube nira 400W 

I found these specs:

+3.3V 20A

+5V 14A

+12V1 14A

+12V2 13A

-12V 0.8A

+5Vsb 2.5A

Somebody told me on tom's hardware forum that "According to Asus you need about 225W = 19A at 12V" and this PSU got only 14 amps on the 12V (don't know why there are 2 12Vs in the specs though)

And I don't even know where did the got those numbers.

EDIT:

Here's a picture of his post

One of the 12v is for the PCI-E power connector, and the other 12V is for molex+sata power

So if you put then together with the adapters it is 14+13=27A which should be enough

I would get a cheap Corsair one. Like the CX430M. It's reliable and really cheap.
