Will 300W be enough for this?

Will 300W be enough for this PC?

CPU: Intel Core i5-4590S
GPU: GTX 960 (or if it takes up too much power I'd go with 950)
RAM: 2x8GB
1xSSD 1xHDD 5400RPM

Whats the psu?

 

[InvalidError]

In principle, yes. In practice, it depends on the PSU's quality and output power distribution.

 

[nukemaster]

The low power draw of the cpu helps for sure.

What power supply are you getting?

 

[SweMan574]

I have a mini-ITX system so I want it to be as small as the be quiet! PowerSupply (PSU) TFX Power 2 300W Gold PSU. Will that be any good?

 

[nukemaster]

Edit. Is it the actual be quiet unit?
http://www.bequiet.com/en/powersupply/496

That has 288 watts on its combined 12 volt rail(24 amps).

It should work(as long as they are accurate with the specs), just do not plan too much overclocking or anything since that adds up.

Old post....

The power supply should have specs.

Something like this.

This example is a multi rail unit.

Thanks. I won't do any overclocking. A PSU Calculator site said my load wattage would be 289w and recommended PSU wattage would be like 347w. And if I change the 960 to the 950 it would be 247w load and like 302w recommended. I also go with the mini versions, so they fit in my In Win BP671 case.

I also have to order from a swedish site, so is this the right PSU? http://www.webhallen.com/se-sv/datorkomponenter/198372-be_quiet_powersupply_tfx_power_2_300w_gold?gclid=CjwKEAjwuuy4BRCvs43g9fX9mz4SJACiYydPtFWpezRgouQ77MF_3JAxdEfPwowEty-UjGKbRDXjNRoCdeLw_wcB

That one is slightly different. The specs list 264 watts. Same amount as my picture actually.

I am not seeing a 6 pin pci-e video card connector either.

If you can find something with a little more power it may help(and have the required connector).

If I trust my UPS, my i5 750 + GTX 650ti(this thing is great for power consumption) + WDC Red(3.5) + WDC Blue(2.5) + SSD was drawing in the 150 watt area at the wall when playing games. This system was built with lower power in mind(almost 6 years ago, the video card was swapped from a 5770 to reduce video playback power consumption). I have seen peaks of about 180(I am sure I could get a bit more).

I do not expect your system to be that power hungry, but if i burned mine out by using a 300 watt power supply(now showing any signs of that and it has been nearly 6 years) it is my own fault. I like other users to have a bit of headroom when they can.

 

[SweMan574]

I know, but I can't find a TFX PSU over 300 Watts????

 

[nukemaster]

Have you already settled on a case? Maybe it would be better to look at something that takes SFX(still pretty small) or normal ATX.

Sure it is crammed, but 450-600 watt power SFX units can be had(this one just has 300 watts however).

 

[SweMan574]

I need it to be so small it could fit this case.

[nukemaster]

Do they have small enough 950 and 960's to even fit that case?

It would have to be half height and single slot

2 slot(with a single backplate or whatever they call he slot the card screws into), if the case has room on the side and some way for the card to get air.

 

[SweMan574]

So this doesn't fit? https://www.asus.com/Graphics-Cards/GTX950-M-2GD5/

 

[nukemaster]

Not a chance. It is too thick and too tall for the case you want to use it in.

Those cards are not long, they still need to slots wide and full height.

Low profile/half height cards are like the on on the right side. Please ignore the slot differences, one is an old AGP card.

Your case also needs a single slot.

 

[SweMan574]

What about the Bitfenix Pandora Core then?

 

[nukemaster]

Yes, the Pandora Core is a larger case with room for a standard power supply and can even take an mATX board. mITX and mDTX(same depth as mITX, but with 2 slots) fit as well.

 

[SweMan574]

Do I have to use a mini GPU with that?

 

[nukemaster]

No, you can use video cards upto 13 and 3/4 inches in that case.

Because the case is not very wide just ensure they are not too tall.
