Hi;

I currently have one of these uglies: http://www.ebay.com/itm/HP-DPS-600WB-A-PC-power-supply-P-N-633186-001-600-Watts-/191705878649

I have a EVGA Nvidia GTX 970 SC which requires 38A on 12V rail(2 X 6 pin). So the PSU is not enough.

I want to change my PSU but I'm not sure what to get. I've found this guy(https://www.newegg.com/Product/Product.aspx?item=N82E16817139040) but I'm not sure if this is a good one for me since I can't see 2 X 6 pin 12V connectors.

My Specs:
* i7-3820 @ 3.60GHz
* 16 GB ram
* EVGA NVidia GeForce GTX 970 SC
* PSU: Model HP dps 600WB-a
* 2 Hard drives (raid 0)

Motherboard:
Manufacturer: Pegatron
Manufacturer name: IPIWB-PB
HP name: Pittsburgh2

Please suggest me a good PSU for my unit.

P.S Budget < $100, PSU >= 600W

Don't worry. I have already considered that part in your opening post. All of the power supplies I listed have AT LEAST 2x 6-pin connectors for you to plug into your GPU. Some have 2x 6+2-pins, some have 1x 6-pin and 1x 6+2-pin (both of which also can be used as just 2x 6-pin in total, with the 2-pin left unplugged). Everything I listed is compatible.
I wouldn't get that CX750 based on its mediocre quality/poor reliability. For your setup, you also don't need a 600W PSU as it way too much of an overkill. A 500W PSU can do the job, even a ~450W good-quality PSU.

Your GPU will not consume more than 200W at its peak/max. load: https://www.techpowerup.com/reviews/EVGA/GTX_970_SC_ACX_Cooler/23.html
Your CPU has a 130W TDP (http://ark.intel.com/products/63698/Intel-Core-i7-3820-Processor-10M-Cache-up-to-3_80-GHz) *roughly* translates to 130W, but for more headroom, let's say 150W (includes other components already)
So, in no way, you will use more than 350W max power draw.

Tests show that a rig built around your GPU draws only 293W at full system load (https://www.bit-tech.net/hardware/graphics/2015/05/08/evga-geforce-gtx-970-ssc-acx-2-0-review/8).

Getting any of these ~500W PSU is *more than enough* really:
Antec High Current Gamer 520W 80+ Bronze Certified Semi-Modular ATX Power Supply ($91.85 @ Amazon)
SeaSonic 520W 80+ Bronze Certified Fully-Modular ATX Power Supply ($62.89 @ Newegg)
Corsair RMx 550W 80+ Gold Certified Fully-Modular ATX Power Supply ($99.90 @ Newegg)
EVGA SuperNOVA G2 550W 80+ Gold Certified Fully-Modular ATX Power Supply ($79.49 @ SuperBiiz)
EVGA SuperNOVA G3 550W 80+ Gold Certified Fully-Modular ATX Power Supply ($84.99 @ SuperBiiz)
SeaSonic G 550W 80+ Gold Certified Semi-Modular ATX Power Supply ($69.99 @ Newegg)
XFX XTR 550W 80+ Gold Certified Fully-Modular ATX Power Supply ($83.99 @ SuperBiiz)

Hope this helps.
 



I see, I'm curious about the connections. I need 2 6 pin connectors with enough amps on them. I looked at your suggestions and I don't know how to determine if any of them has that configuration
 


If you click on the link for each power supply, you can see what connectors they have.
 


Well, I did of course.

I see 1 or 2 6+2 pin PCI express connections mostly. Can I use 6+2 pins for 6 pin connections for the GPU?
