GTX 750 With 265w PSU????

May 29, 2017 at 08:06:46
Specs: Windows 10
I think I made a huge mistake.. D: I have a Core i3 2120, 6 gigs of ram, and just bought a GTX 750, thinking it would work with my PSU. I only have a 265w PSU. Will it work? I hope it will.. please reply. Thanks!

Simply put, you need a larger (higher-output) P/S.

Well I know that.. but I'm on a very tight budget. Should I wait to install it after getting a new PSU?

If you draw more current (thus higher power) than the machine is capable of sustaining, then you'll be buying a new P/S anyway (and possibly other components that could be damaged). In essence, yes, wait for the new P/S. And don't scrimp on it either. 400W would be the minimum I would consider.

Okay.. but in the mean time would taking out the optical/cd drive make it work?

I heard that they take up 20-30 watts of the power...

The reason you buy a P/S that's rated higher than the sum of the components of the board is twofold:

1. Always buy something that can handle more than all components/peripherals in the "on" state (i.e. "derating"):

https://en.wikipedia.org/wiki/Derating

2. The current status of P/S manufacturers is a joke right now. Those rated 400W can likely do around 300.

It's your system. If you want to experiment with removing/adding components, then there's nothing I (or anyone else on the board) can do to prevent you from doing so. But be prepared for the consequences should something go horribly wrong...

Well, assuming you have a standard physical size PSU then the link below is for you. However, the fact that you currently have only 265W PSU may indicate you have a small case of some sort. Post the model number from the back of your current PSU.

"in the mean time would taking out the optical/cd drive make it work?"

The optical drive only requires power when it's in use, so disconnecting isn't going to make a difference.

Newegg has several Corsair PSUs on sale. The CX430 is $20 after rebate, the CX450 is $25 after rebate. There are also VS-series PSUs on sale, but that is their "value" line; the CX-series is their intermediate line. I have the CX430 in several of my builds with higher wattage requirements than your i3 with GTX 750.

BTW, did you get a 750 or a 750 Ti? The plain 750 is kind of an odd choice.

The plain 750, just because it was only $40 on ebay.

Both riider and myself provided links to PSUs that cost only $20 after rebate. Why are you looking elsewhere?

Your link is NG.

I also asked you for the model number of your current power supply. That would tell us if you have a small form factor PSU or a standard size. If you buy the wrong one, it won't fit.

If you don't see a model number, do you have a brand name computer? If so, what model?

It's standard size. Also, rebates take a very long time. I know it will fit, because it is ATX. Thanks very much for all you're help guys!

So, rebates take a long time!! If you over stress your current PSU and it fails you will be spending a lot more than $40, which is the cost before rebate. Good luck.

Too bad you didn't post a link to the PSU you're buying. We could have told you if you made the right choice or not. If you paid $40 or more & didn't get a decent one, you wasted your money. You could have gotten a Corsair unit for the same amount of money, then gotten $20 back in 6-8 weeks.

Can I just chime in and say I'm surprised a 250W PSU would have the required 6-pin GPU connector? 'Cause that's something the 750 needs to run.

Razor: The GTX750 does not use the 6pin, in fact, many of the GTX750Ti do not either, though the one I am using does because I wanted the ability to tweak the already factory OC if needed (thought not needed).

You have to be a little bit crazy to keep you from going insane.

You're right; I was thinking of the GTX760, 'cause one of those died on me that morning.
