Power Supply Help

[Elmaes]

Hello, so i have a lenovo pc (e73) with core i3 4160 and 4Gb ddr3 memory and i want to change the power supply.
So my question is,
Can any pc get its power supply changed ? Or there are permanant power supplies?
Thanks in advance.

There are several different form factor power supplies such as standard ATX or Small Form Factor (SFF). Yours happens to use an SFF 180 watt. It gets tricky trying to upgrade OEM built PC's because they sometimes use proprietary power supplies that have odd dimensions or are wired differently, and trying to use an aftermarket PSU may damage the system. Best to check on the Lenovo forums to see if anyone else has upgraded their identical PC to make sure it will work before trying it.

A SFF PSU doesn't exists, it's ATX, FlexATX, SFX, TFX or custom form factor for consumer PC's.

Sorry guys, but im new to PCs world, i just wanna know if its replacable or not

 

[BadActor]

Sorry, I used the generic term for an SFX, but that is correct.

In technology, yes everything is replaceable.

Okay, do new PSUs fits this case eVGA 500W PSU fits that case ?
and can i run GTX 750Ti OC 2GDR5 after upgrading the PSU ?

 

[PSUGod]

Why do you want to replace the PSU?

 

[Elmaes]

To run the graphics card

 

[Elmaes]

I need to Run GTX 750Ti 2GB DDR5 and it needs 300W and mine is 180W

 

[PSUGod]

No a GTX 750 Ti doesn't need 300W PSU, it only takes around 60W for a standard model.

So if you're gonna buy a non OC model, you should be fine. Just look if it's fits in the case.

What's the minimum recommended wattage for a GTX 750Ti? What processor is being used? Does the board even have a PCIe x 16 slot? Does the Bios allow for the card used? Do they need a low profile card? You need to answer all these questions before you go recommending someone use a graphics card in an OEM. It may work no problem, or, they may end up with a card they can't use, or it might pop the PSU and destroy all their components.

 

[Elmaes]

Minumum recommended is 300W
Core i3 4160 3.6GHz
dont know the other questions sorry :/ but i dont want to risk so is the eVGA 500W a good option ?

 

[Elmaes]

Actually 300W is not the recommended; its the required :/

 

[PSUGod]

What's the minimum recommended wattage for a GTX 750Ti?

There isn't any, it just depends on the other components.

What processor is being used?

He already said that, a i3 4160.

Does the board even have a PCIe x 16 slot?

It does

Does the Bios allow for the card used?

It should, it's not an old motherboard, so it should support modern UEFI cards.

Do they need a low profile card?

Already said that he should look if it's fits.

OEM systems don't use crappy PSU's. They use PSU's from Lite-on, Delta, Acbel, or other big manufactures.

No it's not, it would even fit if you have a Lenovo E73 mini tower and the quality could even be worse.

Actually 300W is not the recommended; its the required :/

Already told you, it's not.

 

[Elmaes]

But, on nvidia website that is what said ! and yeah the PSU manufacturer is AcBel.
But then what PSU would you recommend me ? i just dont want to risk
and notice that i also want to higher the ram from 4gb to 8gb

 

[PSUGod]

But, on nvidia website that is what said

nVidia can't recommend you anything, because they don't know the other components.

and notice that i also want to higher the ram from 4gb to 8gb

The power consumption of memory is extremely low, only a couple off watts tops.

 

[Elmaes]

So what PSU would you suggest me ? i can pay like 50$
and what GTX 750Ti 2gdr5 shall i get ? (eVGA,Asus,ZOTAC..etc.) ?

 

[PSUGod]

Seriously?

and what GTX 750Ti 2gdr5 shall i get ? (eVGA,Asus,ZOTAC..etc.) ?

Well do you have a mini tower or midi tower?
Left or right: http://www.lenovo.com/shop/emea/content/pdf/ThinkCentre/Edge/en/E73_DS_EMEA.pdf

 

[Elmaes]

The left one (the higher one)

 

[PSUGod]

The left one (the higher one)

Well then a normal GTX 750 Ti should fit fine, also no need to replace the PSU, just buy a non OC GTX 750 Ti, without an external power connector.

 

[Elmaes]

Wont i be at risk ?
and the eVGA one doesnt need that external power connector, right ?
and it is 2gb now 1gb ! is it okay ?

 

[PSUGod]

Wont i be at risk ?

Nope, a decent PSU also has Over Power Protection (OPP) but you PC with GTX 750 Ti only takes around the 120W out of the PSU. So even without OPP there isn't a problem.

and the eVGA one doesnt need that external power connector, right ?

Which EVGA? Do you have a link?

and it is 2gb now 1gb ! is it okay ?

A 2GB version is a bit better.

 

[Elmaes]

I heard that ive to have something like 6A in 12V rail something like that :/ how can i know if i have it ?
And yeah:
eVGA : http://goo.gl/sA7cAg
ZOTAC : http://goo.gl/7ckBTR

Which one is better ?
