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!)

Hi

You need to report on the data plate of this cheap PSU or post a picture
what is important is how many amps on 12 V line(s) are available

According to Asus you need about 225W = 19A at 12V for the GPU and also enough for the CPU

there are Pci-e 6 pin socket to 8 pin plug adapters available
but the question can the PSU safely put out 20 Amp to graphics card while supplying the ATX 12 V to CPU
What cpu?

VGA resolution is 640 x 480 and long dead
(1024 x 768 is usually minimum found on old or small screens)
is his screen CRT or LCD ?
VGA connector db-15 3 rows of pins usually with a blue plug does not give resolution

does he have an DVI to VGA adapter ?

His monitor is not so old, it's an LCD monitor with 1680X1050 resolution, and yes he's got every adapter he needs (everything got from me). I will just go to his house and take a picture of it.

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
20+4pin M/B x1, 4pin+12V CPU x1, 6 pin PCI-e x1 , Peripheral x5, Floppy x1, SATA x4

Hi

Depending on graphics card bios it may detect lack of power from 6 pin connector and refuse to post
Or driver may give warning
Or it may work until you play a game then psu will burn out possibly damaging other components

You need at least 20 Amps on a 12V line and you have 13Amps available

Suggest you use integrated graphics chip or CPU or a old graphics card which can run on 10 Amps 120 Watts until new psu can be purchased
