Hi I am about to buy a cyberpowerpc computer. Should i get a 600 Watts - EVGA 600 80 PLUS Power Supply or a 1,000 Watts - Standard 80 Plus Gold Power Supply. They are both the same price and I have no clue. I will be doing high end gaming on this computer with a gtx 970 gpu i5 cpu overcooked by 15% and 16gb of ram. Thanks in advance

The evga 600 is a fairly mediocre budget PSU butbis at least reliable , the fact a 1000w gold is coming in at the same price would set alarm bells ringing.
Is it 'gold rated' or just gold coloured ?? I wouldn't trust a cyber power listing at all.

Oh yeah - build your own - I second that , or at least try a find a smaller/private PC builder because theyllnputbmore carec& attention in & let you pick your own components properly.

A 970 & i5 combo deseverves a good 600w seasonic/superflower unit really not some cheap generic model.

In all honesty you wont get much help here mainly because Cyberpower is seen as one of the worst OEM computer manufactures out there. I myself have seen multiple problems such as their water pumps dying just after the warranty expires (a year) or my all time favorite which was a system that had the motherboard mounted directly to the tray using no stand offs causing it to short out and fry the system.

Seems you don't have very much knowledge in the computer field, so I'll explain.
Wattage on a PSU will be based off of the components within your computer and how much wattage they take up. For a vivid example, dual Titan-X SLI's will require a hell of a lot more wattage than a single GTX-960.

I cannot answer this question until I get a list of the specs.
Also, if this is a prebuilt.. the wattage should be set accordingly to the components within; So why does this really matter?
1000 watts within one of those prebuilts probably means that it has more beefier components that use up more wattage; ideal for gaming.

I updated this forum with my specs.

The 970 will determine your PSU size

http://www.geforce.com/hardware/desktop-gpus/geforce-gtx-970/specifications

70 Thermal and Power Specs:
98 C = Maximum GPU Tempurature (in C)
145 W = Graphics Card Power (W)
500 W = Minimum System Power Requirement (W)
2x 6-pins = Supplementary Power Connector

SLI - 500 + n x (145 +20 peaks) = 665 watts for 2 cards

http://www.guru3d.com/articles_pages/nvidia_geforce_gtx_970_and_980_reference_review,7.html

Subjective obtained GPU power consumption (970) = ~ 164 Watts
Subjective obtained GPU power consumption (980 )= ~ 171 Watts

Here is Guru3D's power supply recommendation:

GeForce GTX 970 or 980 - On your average system the card requires you to have a 500 Watt power supply unit.
GeForce GTX 970 or 980 in 2-way SLI - On your average system the cards require you to have an 800 Watt power supply unit as minimum.

If you are going to overclock your GPU or processor, then we do recommend you purchase something with some more stamina.

Not that as Guru3D used a 230 watt OCd CPU in their test, you can get by with a 750 watter no problem... the EVGA B2 is a solid buy and usually about $50... today $45

In my personal opinion, 600 watts is the way to go. That's just me though.
Also, according to the responses I've seen, CyberPowerPC has a horrid reputation. You'd be better off looking for a company that wont screw you over. Again, personal opinion. Your choice.

so i looked at the bench marks and itg says the gtx 970 needs 500 watts. So that means i will be good with 600 watt psu?

I would say their reputation is a lot more than just personal opinion.

OP, of the two the EVGA would be the best but honestly it is not worth buying from a company who to the more tech savvy of the world avoid like the plague. You would be better off buying from Asus (if you want a decent OEM) or building one yourself or having a friend do it.

Not sure what benchmarks have to do with PSU sizing but yes, I quoted two sources:

1. nVidia who makes the 970 said you are fine with 500 watts
2. Guru3D who tested the 970 by measuring power draw "at the wall" and said 500 watts is fine

Not sure why there's still a wattage question here. That being said, I recommended a 750 watter because:

a) that particular unit I linked to is better quality than the offered unit.
b) It is cheaper than the offered smaller PSu
c) You can add a 2nd GFX card down the line.

I would not use an EVGA B1 / G1 model in a PC build no matter if it was 500, 600 or 100 watts

B2 yes
G2 yes
P2 yes
GS yes
B no
B1 no
G1 no
