Dear Community,

Please advice. I wonder if change of my power supply to stronger/better/newer will help to speed up the PC, especially 3D performance of my graphic card.

I do play games. I do work on my PC.

My current Power Supply: Chieftec GPS-450A → 450W

Code: 
Intel i5-2400 @ 3.10GHz
8.00 GB RAM
Motherboard: Asus P8 H61 PRO
NVIDIA GeForce GTX 760 (2 GB i believe)
Windows 10-64bit

Please help me to understand.
1. Can better Power Supply speed up my computer?
2. What Power Supply I should by (brand/class/power) if it is recommended to upgrade?

Thanks

A power supply only provides electricity to the parts of your PC that need electricity. It is these electrical consuming devices that make your PC fast or slow.

To speed up your graphics card you need a new graphics card, not a new power supply. In order to use the nicer video cards, you will need a fancier powersupply but that is not because the power supply makes the card faster but because it can provide it the electricity it needs. A graphics card upgrade can be fairly reasonable.



A GT 1030 video card would be around $70-80 and a fair bit faster than what you can now. The fastest video card that works in essentially every PC, is the GTX 1050ti.

Example 1030...

From what I have read that particular Cheiftec supply is made by Delta and is considered a decent one. No need to replace.

No real performance difference can be gained with a power supply. Aside from mild efficiency improvements and less noise/ripple. Motherboards and GPUs have their own voltage converters. A better power supply just takes a little strain off of them.

I think the GT 1030 would be a performance downgrade relative to a GTX 760, wouldn't it? AT least, based on the hierarchy chart, the GTX 760 is 4 tiers higher than the GT 1030.

On the plus side, the 1050, 1050Ti, and 1060 all perform better than the GTX 760, while all also consuming less power than the GTX 760.

I think, and again, this is going strictly by the hierarchy chart, that the 1060 would, of those 3 I listed, be the only one that offers a noticeable performance gain.

Uff, you're right. I misread that. I thought he had a 730.
The 1030 would be slower.
The 1050ti would be an upgrade, but only 10% or so faster. The 1060 would be significantly faster (20% or better).

Thank you everyone for explanation and suggestions! Really appreaciate. Great forum.

So, GeForce GTX 1060 is the best what I can apply to my motherboard? ( Asus P8 H61 PRO).

Is that the best what I can do? How helpful would be to change processor to i7 for example?

Will my 450W Chieftec handle this power consumption?

(I think the most efficient is to continue in the same thread)

Thanks again!

Yes. The 1060 is a more efficient GPU, better performance with less power consumption than the GTX 760.

The GTX 760 has a TDP of 170W
The GTX 1060 has a TDP of 120W

So, if your current power supply has managed fine with your existing GTX 760, then it should easily handle the less-demanding GTX 1060.

Some games may benefit from the i7 CPU, but I believe you will see a bigger improvement with the newer GPU.

What resolution and refresh rate is your monitor? If you have a 1920x1080 screen, the GTX 1060 (I recommend the 6GB version instead of the 3GB version) will handle your needs perfectly with the details turned up high.

I would stick with the i5 until it really can't do what you want. Then upgrade the entire platform. Unless you find a really good deal on an i7-2600, or possibly i7-3770 it is better to invest in a new processor. Quite a few improvements in 5 or 6 generations.

Any GPU that only requires one 6-pin PCIe connector will work with your power supply. GTX1060 is a pretty good choice. Probably a little too fast for the CPU, but no reason to limit yourself. You can always re-use the 1060 along with a new processor/motherboard/ram.

Exactly 1920x1080. I will go for GTX 1060 with 6 GB then. Future focused, so to speak.
I will stick to i5 for now and replace whole unit in the future.

Thanks everyone for explanation. I had no idea that newer card can have lower energy consumption.

Grat community!
