will my PSU run a gtx750ti?

Recommended Posts

Posted · Original PosterOP

so... i buy an ASUS GTX 750 TI OC 2gb. the page say that i need 300w and i wonder if my thermaltake 350w will run it. the GPU needs a 6pin connector but my PSU doesn't have one so i need to buy a molex to 6pin adapter.

my other specs are:

ASUS h81m-k mother board

Intel i7-4770

1x4gb ddr3 ram + 1x2gb ddr3 ram

1xHDD 7500rpm 1tb

11HDD 7500rpm 500gb.

i put some photos of my PSU and GPU

 

my english is terrible...sorry.

Could it? Maybe.

Should you? No.

 

It is a low end low quality psu that is quite old already. I would not trust it to power anything else than what you have now. The gtx750 can be too much and cause issues that could lead to the death of your computer as the psu can't handle the extra power draw.

 

So until it is replaced with a QUALITY unit I would not upgrade anything.

Does that card need PCIe 6 power? Most 750 ti’s don’t... they just use mobo PCIe slot power.

 

If that is the case, it’s like ok. Not the best PSU, but.... that GPU won’t draw a lot of power if it doesn’t need 6 pin power. If it does, technically the PSU has the wattage, but 16 amps on the 12v rail is not a lot. If the card needs 6 pin power, I would be weary of using the PSU.

If the PSU lacks a connector it's because it can't power a graphics card that uses said connector.

 

duh I know, I know, my genius is almost frightening sometimes but it's a pretty obvious reasoning imo. I like the heater example for these kind of scenarios, let's say you buy a heater that comes with a plug that's 20A but your kitchen only has a 6A outlet, you could get an adapter or replace the plug of course... but why would you do that? your heater needs 20 amps but you only have 6 available, would you still plug it in? it won't really cause a fire most of the times but the outlet will melt like butter.

i mean... probably? As with anyone who comes to the forum with their local potential fire-hazard i recommend you get a new PSU as well, preferably one with an actual PCIe 6pin but i have a feeling you wouldnt have that 750TI if you had that budget atm


I spent $2500 on building my PC and all i do with it is play no games atm & watch anime at 1080p(finally)...

molex to 6pin should be fine considering it's not a very power hungry card, most 750 ti's don't even have any kind of power connector just like my zotac one, even with extreme co it shouldn't use more than 100w considering it has only 60w default tdp

The 750 TI is one of the best GPUs to run on crappy old power supplies so I would say it's fine.


I WILL find your ITX build thread, and I WILL recommend the SIlverstone Sugo SG13B

i7 8086k (won) - EVGA Z370 Classified K - G.Kill Trident Z RGB - Force MP500 - Jedi Order Titan Xp - Hyper 212 Black (with RGB Riing flair) - EVGA G2 650W - Black and green theme, Razer branwashed me.

Draws 400 watts under max load, for reference.

 

Linux Proliant ML150 G6:

Dual Xeon X5560 - 24GB ECC DDR3 - GTX 750 TI - old Seagate 1.5TB HDD - Dark moded Ubuntu (and Win7, cuz why not)

 

How many watts do I need? Seasonic Focus threadUserbenchmark (Et al.) is trash explained, PSU misconceptions, protections explainedgroup reg is bad
