Power requirements for GTX 750

[Urkedurke]

Yes hello,
I want to buy a GTX 750(http://www.geforce.com/hardware/desktop-gpus/geforce-gtx-750-ti/specifications). My motherboard is compatible I have enough physical space BUT I dont know of my power supply. Here is a picture of my sticker (http://postimg.org/image/h8bpd8h9d/).
The thing is I don't know if I have a PCI-E power connector. I don't think it dose and i might need to get a new power supply. I found this one at my local store,(http://www.lc-power.com/index.php?id=184&L=1).
Here are the specs of my current supply:
Model: TM-500-PSAPI3-IT
Output Power: 500W
Standard: ATX 12V v.2.2
Certificate: -
Switch: a
PFC: Passive PFC
Connectors:
1 x 20 + 4 pin
1 x 8pin (4 + 4) + 12v
3 x SATA
2 x Molex 4 pin
1 x Floppy
Voltage branches: + 3.3V (30A), + 5V (30A), + 12V (20A), 12V (0.3A), + 5Vsb (1.5A)
Protections: OVP (Over Voltage Protection); UVP (Under Voltage Protection); OPP (Over Power (Load) Protection); OCP (Over Current Protection)
Efficiency:> 65%
Fan Dimension: 120mm
Dimensions: 150 x 140 x 86 mm

Thanks.

What is the exact model of that Gtx. From what I remember most if not all take power from Pcie slot. Some custom pcb versions might require external power tho.

Yo,

Your current PSU should run the card fine, here are the requirements for the 750.

GeForce GTX 750 - 20A and a 400W PSU minimum

You have 20 amps on the 12+ volt rail so you're good there and you have a 500 watt powersupply so you have enough food to feed the card!

You can get a 2x molex to 6 pin PCI here

Every things compatible.

No additional power than Pcie slot required, so no you don't need those molex adapter which in fact shouldn't be ever used.If PSU doesn't have it then it's either a very old PSU or very cheap one. One way or another this doesn't sound good. Those adapters should be advised either for people who know what they are doing or confirmed by people who know what they are doing. 12V * 20A = 240W. So no it's far from safe without further investigation. What is the PC specs, all of them?

Yo nerdywhatever why don't you at least do some research before posting statements which might cause OP's PSU sound like a jet engine and start to smell funny.

Edit: Back to the OP again. I've searched something about the PSU you already have, as expected results are not well. It's a low end model with horrible efficiency and if it's also few years old it's even worse news. You should really consider at least some decent grade one if you want to invest in a proper GPU. The one you picked is not that any better as well. It has 2 separate 12V rails which in this case are useless since both CPU and GPU will drain only one. The is XFX TS 550 for 27$ which will be vastly superior to anything in that price or even cheaper Corsair CX 430 for 20$ which maybe is not a killer but certainly should give you some calm sleep. But certainly it would be nice to see the res of the parts of the PC to put a final verdict.

He wants to run a 750, not exactly a 'high spec', 'demanding' video card is it...

His PSU will work fine, yes it probobly is cheap although these are the sort of PSU's that are packaged with BRANDED pc's which have even higher end graphics card than this card. The fact that you just 'know' that his PSU is going to pop or sound like a 'jet engine' isn't accurate to me, regardless of how much experience you may have, his PSU is compatible, him not having a PCI 6 connector doesn't mean anything, the PSU has enough amps and enough watt's, if he were to put a 970 in tthere then yeah POP bang, house on fire but he's not using a demanding card therefore I don't want to make him fork out a load of extra cash to buy a new PSU.

Sorry this isn't paragraphed.

Thank you both very much.
