Need a new PSU for my rig

LeGeNdSChAoS · Jan 10, 2017

Hey guys, recently I created a thread where I was asking for help because my PC kept randomly shutting down. Well some dude helped by saying that the power supply I used just wasn't enough to keep my video card running thus everything crashed.
Now I'm struggling to find a new reliable cheap PSU because I'm on a tight budget and I'll be very grateful if someone helps me with this. Also I'd like to note that I'm from Bulgaria and some of the brands that are in the USA don't ship to here.

Components:
Motherboard: Asrock H81M-VG4 R2.0
CPU: Intel I5 4460 3.2Ghz
RAM: Dual Channel 4GB DDR3
GPU: Nvidia GTX 960 Asus OS version 2GB VRAM
PSU: Thermal Master atx12v 500w
HDD: Seagate 1TB
SSD: Samsung Evo 850 250gb
CD/DvD reader

So 500W is not enough? Hmmm...
Then 600W should be. Here are 2 suggestions of mine from amazon.de, they should ship to you.

Corsair: https://www.amazon.de/Corsair-CP-9020098-EU-Serie-VS650-Netzteil/dp/B00LMBT0IO/ref=sr_1_2?ie=UTF8&qid=1484072107&sr=8-2&keywords=corsair+600w

Cooler master: https://www.amazon.de/Cooler-Master-ver-2-PC-Netzteil-RS600-ACABB1-EU/dp/B00MV5YA08/ref=sr_1_1?ie=UTF8&qid=1484072199&sr=8-1&keywords=coolermaster+b600

Well the actual GPU requires a 450W or higher PSU but as stated from a person I've talked to earier:
"With a 20 amp +12v rating, it is more like a 250 watt power supply. You need a quality 400 watt or greater power supply for the GTX 960. Most of the Thermal Master 500w power is allocated to the +3.3v and +5v rails where you don't need it."

So I'm not sure what I want to buy at this point because I really don't want the PSU to brake my other components.

LeGeNdSChAoS :

A PSU can't just brake you components...where did you hear that?

Just buy a PSU from a trusted brand like Corsair, EVGA, Cooler master and you will be fine.

But as I look at other people's rigs I think the 500W Cooler Master B500 V2 should work.. but I'd want some confirmation for this because I don't want to spend more money on hardware that will blow within a couple of months.

ZaneDragon :

Well I heard that the prolonged usage of a low end PSU can damage the hardware in long term. I don't know if it's true of course, I don't have that much experience with computers yet.

System Power Supply Requirements for a single ASUS GTX 960 STRIX OC 2 GB [STRIX-GTX960-DC2OC-2GD5]
• ASUS specifies a minimum of a 400 Watt or greater system power supply. (Minimum system power requirement based on a PC configured with an Intel Core i7 3.2GHz 130 Watt TDP processor.)
• the system power supply must also have a maximum combined +12 Volt continuous current rating of 28 Amps or greater
• the system power supply should also have at least one 75-Watt 6-pin PCI Express supplementary power connector.

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.

Thermal Master ATX12V 500W
• maximum combined +12 Volt continuous current rating: 20 Amps <===== Insufficient
• No PCI Express supplementary power connectors <===== Insufficient
• Passes Official Intel Haswell Compliance Test: No
• No 80 PLUS Efficiency Certification

And will the 500W Cooler Master B500 V2 be appropriate for such a video card?
