GTX760+i5 power supply prob?

[danilopon]

Hello,my custom made gaming pc (low budget) has finally came to me ,only to realise that it has problems! So at random times,playing lol (11minutes or so) my pc froze and then i waited for about 5 minutes and it shut down..after that i pushed the button and the fan almost worked then shut down like there was no power.then i did it again and open perfectly! but at sometimes the pc only shut downs! I think the one who i tasked to do the pc did a mistake and bought a low budget PSU
Specs:
i5 4440
nvidia gtx 760
1x kingston ram 4 gb
Gigabyte ga b85 hd3 motherboard
Intel ssd 330 series 60 gb sata 2,5
and hdd 500 gb
PSU: BITMORE 450W (dont ask me about bitmore i think its some shitty brand)
what do i do?

Thanks in Advance !

Well, your GPU says is need at least 500 watts!

The PSU may say 450 watt but there is a high chance that it is a 350 watt.
Most cheap odd brand PSUs talk big, but can not give anywhere close to there power ratings.
I just had to throw away a cheap 430 watt PSU because it could only produce 350 watts.
When you get another PSU make sure you get one with high watts and amps.
I recommend EVGA, Corsair, and Sesonic. They all make good PSUs.
Your system is power starved. That will cause tons of problems.
Get at least a 600 watt PSU with a +12v 30+ amp rail!

This should do the job:

Happy Computing!

also unkwon power suppl yis a bad idea while whith a quality unit of that watige you could just scrape by with a unkown likely crappy unit like that its likely going to cause sever problems

I own a GTX 770 and i7 870 and with both going full out they barely break 450w. Your PSU wattage should be fine. However bitmore is most likely crap, and doesn't supply enough amps longterm.

This one will power anything you need, and do amazingly at it. It only has 1x6-pin though, so if you need two you will need to get the 450w. Seasonic is the gold standard though, and you pay for that. If you want a cheaper one I recommend corsaid and rosewill.

First of all thanks for answering so fast! I really appreciate it.
So u think the problem is the PSU ah?
Sadly i cant afford Seasonic in my country they are expensie but can u do me a favor and choose something from this? The budget is 50-70 Euro

Go with Corsair!

For a system using a single NVIDIA Reference Design GeForce GTX 760 graphics card NVIDIA specifies a minimum of a 500 Watt or greater system power supply that has a maximum combined +12 Volt continuous current rating of 30 Amps or greater and that has at least two 6-pin PCI Express supplementary power connectors. Some of the non-Reference Design GeForce GTX 760 cards have a single 8-pin (e.g. ASUS GTX 760 DirectCU II OC) or two 8-pin (e.g. MSI GTX 760 HAWK) or one 6-pin and one 8-pin (e.g. Gigabyte GTX 760 WindForce OC, EVGA GTX 760 SC w/ACX Cooler, MSI GTX 760 TwinFrozr Gaming) PCI Express supplementary power connectors.

Total Power Supply Wattage is NOT the crucial factor in power supply selection!!! Sufficient Total Combined Continuous Power/Current Available on the +12V Rail(s) is the most critical factor.

Take a look at the label on the power supply to see if its maximum combined +12 Volt continuous current rating is 30 Amps or greater. I highly doubt that it is and I highly doubt that it has two 6-pin PCI Express supplementary power connectors also.

Both are definitely good, but XFX has had a slightly blemished past. Go corsair. (Seasonic makes most corsair PSU's insides anyway.)

 

[ko888]

All of XFX's PSUs are made by Seasonic.

There's very few Corsair's current models are made by Seasonic anymore. The HX650, AX760 and AX780 are the only current models remaining that are made by Seasonic.
