A psu of 300w and i5 650 able to support: (1) r7 250x (Y/N) (2)gtx 750ti (Y/N) (3) r7 360 (y/n) 4) r7 260x (Y/N)?
Will it bottleneck the games or lagging. Will be running on med/high no aa. Achievable to 60fps or lesser than that?
Games are: mgsvpp,bf3,4,hardline. Mw3,aw,ghost and bo2. Crysis3 and ac unity.

If the 300w PSU is made by Seasonic or some other good brand sure.

Otherwise I would not push it. Don't get me wrong I'm sure you can get it working. And the PSU won't cause a bottleneck, but if its a low end PSU 300w is its max and you'll be pushing to its limit.

(1) r7 250x (Y)
(2)gtx 750ti (Y)
(3) r7 360 (Y)
(4) r7 260x (N)

Some games will be fine at medium settings, but especially MGSV, Crysis and Unity will be really hard to run at 60fps i dont think that these will run at constant 60fps at any settings. Maybe at low settings.

And there shouldnt be any bottleneck on any of these GPUs.

I too would be interesting in who made the power supply.

I have an 300 watt unit with 22 amps(It is FSP branded in case you are wondering) on the 12 volt rail and it has no issues with a similar system(5 years 24/7[restarted for updates and shut down for cleaning from time to time] and still going).

I5 750, GTX 650ti, 8 gigabytes of memory, 1 x 2.5 inch drive(low power) 1 x 3.5 inch(RED so low power) and one ssd(low power). This system even had a 5770 for a over a year without issues.

It does come down to power supply quality and other items in the system. My system has an mITX board so that is power friendly as well.

Ok the PSU's in there really aren't meant to be pushed, if you look closely at it, it should say Delta or FSP as the manufacturer (possibly).

So the PSU is not a fire hazard, and should work for what you are doing. But over time you may find stability issues, and you will want a better PSU. For now, it will work. Also if the cards need a power plug, you may need to use the included adaptors that should come with it, to plug power in from one of the 4 pin molex plugs.

Would you be able to get a picture of the PSU label.

It could be something like this. Note that many multi rail power supplies do not always just ADD rails.

Unfortunately HP doesn't provide that info on their website. You need to get to the side of the PSU and photograph the sticker, its the only way.

I agree with the above user it is weak for a 300 watt unit, but should still run the cards listed by migronesien above.

Your cpu is quite power efficient and that will help.

Remember you are talking all entry to mid level cards(with a 5 or so year old cpu) so game settings will have to be adjusted to get the performance you want.

He can always use the included molex adaptor, they aren't super high power cards. That said its really not the best idea or the strongest. Theres no way that stock PSU has the connector.

This might be off topic, but however, I'm having the same issues right now and I need to solve it.

I have a 300W PSU, i7 4770 (non-k) Uses 84W Of power, 1 stick of 8GB Of ram, SATA 3 Hard Drive. My motherboard supports PCI 3.0

What's the best GPU I can get?

Thanks.

Preferably something like a GTX 750 which does not require external power.

Brini, It is kind of bad form on HP's part to not get the power supplies 12 volt output labeled.

I mean if they want to sell a multi-rail unit it should at least show that.

The 16 and 12 rating are clearly not something that can be attained from a power supply of that rating since 16 + 12 = 28 and 28 amps is 336 watts. I would treat it as a 250 watt unit and guess maybe103 and guess maybe 16-18 amps on both rails combined(making me wonder why it even lists multi rail).

While I do agree a lack of a pci-e connector(6 pin, not 8 for these entry-mid level cards) is an indication of the power supply not being made to run an upgraded video card, in some cases it is age(the bestec unit has been used in many older systems and is not modern my any means.).

In the end, the best bet for these types of units is still the 750ti because it is so power friendly.

Alright, Thanks for the reply everyone,

Can someone just confirm if I can go with the ASUS Strix GeForce GTX 750 Ti OC'ed ? It doesn't require a 6-pin connector. Here's a link : https://www.asus.com/Graphics-Cards/STRIXGTX750TIOC2GD5/

Thanks a bunch for the help, Nukemaster! :)
