My PSU doesn't have a 6-pin cable

[venetskiiviko12]

i could buy one of those cables with molex adapters, but my psu doesn't seem to have a cable that isn't taken to which i would connect the adapters. i found this 1 cable but it doesn't look like it can be connected to adapters. image here:

is there any way i can connect the cable without having to buy a new PSU? i'm on a VERY tight budget

Model name of PSU?
What are you trying to connect?

Generally - if the PSU doesn't have appropriate connectors, then it most likely is incapable of supplying necessary power to the component, you're trying to connect. In case of low quality PSU this also could mean damaged components (and burned down house in worst case scenario).

Looks like a OEM, if you need a 6 pin connector then you needs a supply that is over 300 Watts so you might want to check what your PSU is rated at. Molex adapters can work but you will find that many here will advise against them.

Make+model of PSU and graphics card? Or if the PSU is from an OEM (like a Dell/HP machine), give us the make & model of the unit & the graphics card you're trying to add.

As others have said, those molex to PCIe connectors are generally a bad idea, but it's worth checking.

the psu says 'itd p4' (nothing else) and it has 420 watts, the graphics card i want is GTX 750 Ti

model just says 'itd p4' (420w) and i want to connect a GTX750 Ti

Hmmm... I can't find a specific model. It must have a brand name or something on it somewhere?

How many Amps ("A") does it provide at 12V ? It should have a little table on it somewhere that provides that current output at each voltage level. It might have multiple 12V rails (listed as +12V1 and +12V2). Can you give us that rating for each?

Also, what's the CPU you're running?

A 750ti is pretty low power and you could well get away with it, if you're willing to take a bit of a risk. But it's worth checking out the rest of the system and the 12V rating to make sure you'll be safely within spec. Assuming this is an older unit, you absolutely do not want to exceed spec as there's a good chance it won't even be capable of hitting its rated output for any extended period.

This one? It has less than 290W on 12V rail.
Probably it can support GTX 750 ti (60W card, 300W PSU recommended).
Try at your own risk.

i'm currently running a core 2 duo e6750 but i'm planning to buy a xeon x5460

You need a new better PSU. You be on a real tight budget if/when that pile frys your rig.

 

[venetskiiviko12]

screw it, i'll add extra 50 bucks and i'll get a better psu, x5460 alone takes 120watts, plus the gpu and all the coolers will be way over 420watts...

 

[venetskiiviko12]

i was avoiding this solution because i can barely get any money, but it's better than risking the whole system

As @SkyNetRising says, that's really only a 290W PSU. You'd be looking to run a ~60-70W GPU and a 120W CPU.

Given that system is from 2007, is that the era of the PSU too?

That CPU won't generally hit its TDP under a gaming load, but with fans and storage you could still be pushing towards 200W on the 12V rails, or 70% of that PSU's rated wattage for an extended period of time. On a cheap, 10 yr old PSU. That's a hell of a risk.

Ultimately you need to decide whether it's worth the risk for you. No one can really quantify the risk for you. It'll probably work for a while, but my guess is there's a pretty good chance that the PSU will fail under that load at some point in the not-so-distant future. If (when?) that happens, you might get lucky and it'll just self-destruct gracefully, but there's a fair chance that it'll take some components with it (CPU, GPU, motherboard, etc). Some very low quality PSUs are even genuine fire-risks when they die, so bear that in mind.

If you are looking at a new PSU, just make sure your build has all the standard connectors. Some OEM builds (Dell/HP, etc) have proprietary power supplies and connectors so you can't just swap a standard unit it.

Do you want some recommendations? I notice that unit is 230V only, so I'm guessing you're not in the US?

1.yes, i believe everything i have in this case (probably including the case) is from 2007. the cpu is, the gpu is, the motherboard is, the ram this pc came with was ddr2 1gb, so yeah, the psu is probably from that time as well.

2.i decided i'm not gonna take the risk, the whole build might be destroyed just cos i didn't want to spend extra, and that is just retarded

3. and no, i'm not in the us, i'm in georgia (europe) and my biggest problem is that i can't ship anything from us stores such as amazon, the best i can get is aliexpress, i trust that site and they have some pretty low prices, but they don't have a lot of things, like some higher-end gpu's, and yes, i would like recommendations

(the biggest problem of mine is that 1 dollar is equal to 2.45 of georgian money, so simple 20 bucks would be a lot of money for me)

I've just spent 15 minutes going through that PSU list and I can't find anything I recognise well enough to recommend. Hopefully someone else on this thread has a better knowledge of PSUs to dig something up for you?

Otherwise, is that literally your only online store option? Those pickings are extremely thin!

well there has to be some other more popular and trusted sites that ship here, but i think i already sort of found what i need, i'll keep looking but for now the best i found is a 500watt pcu with all the cables i need, and also with a good price! thanks for everything, i think i can go on my own now :v
