Is this PSU good?

[Joao Braz]

Hello, is this power supply good for my build?
This are my pc specs

Intel i5 4690K 3.5 GHz

Cooler CPU Thermalright Rev B

MSI GTX970 Armor OC 4GB

Motherboard Gigabyte GA-Z97X-Gaming 5

2x Kingston 4GB DDR3 1866MHz HyperX Savage

1x HDD Seagate 1TB SATA III 64MB

1x SDD SSD Kingston V300 120GB

Case nzxt H440

I was recommended to buy this Corsair VS-650W, is this PSU any good?
Is it enough for 2 gtx 970 if i would like to upgrade in the future?
Thanks again 😉

There are better quality psu to get than a Corsair VS650W.
For GTX 970 SLI, getting a 750W would be better, the EVGA G2 750W would be a good choice.

System Power Supply Requirements for two NVIDIA Reference Design GeForce GTX 970 graphics cards in 2-way SLI mode
• NVIDIA specifies a minimum of a 700 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 power supply must also have a maximum combined +12 Volt continuous current rating of 50 Amps or greater
• the power supply should also have at least four 75-Watt 6-pin PCI Express supplementary power connectors. There are some non-reference design cards that require one 75-Watt 6-pin and one 150-Watt 8-pin PCI Express supplementary power connectors or just one 150-Watt 8-pin PCI Express supplementary power connector per card or two 150-Watt 8-pin 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.

Overclocking of the CPU and/or GPU(s) may require an additional increase to the maximum combined +12 Volt continuous current ratings, recommended above, to meet the increase in power required for the overclock. The additional amount required will depend on the magnitude of the overclock being attempted.

Corsair VS650 (SKU# 75-001837 / CP-9020098)
• OEM: CWT (i.e. Channel Well Technology)
• maximum combined +12 Volt continuous current rating: 50 Amps <===== Minimally Sufficient
• two 150-Watt (6+2)-pin PCI Express supplementary power connectors <===== Insufficient
• Ambient Temperature Maximum (i.e. without derating): 40°C
• Modular Output Cables: No
• Official Intel Haswell Compliance: No
• 80 PLUS 230V EU Efficiency Certification
• 3 Year Limited Warranty

The problem is that i need to choose from corsair...
For now i will only be using one gtx 970
Should i get the one above or should i stick to a Corsair CS650M 650 Watt (Modular ) ?

What do you think?

I think you need to make a decision. The VS is good enough for a single 970, even though the VS is pretty much bottom of the barrel (along with Corsair CX). If you wish to sli in future, you will need to upgrade the psu. So, either make plans for sli now and scrap thoughts of the VS650, or make plans for sli in the future and start saving now for the added expense then.

What do you think?

I certainly wouldn't recommend it for GeForce GTX 970 in 2-way SLI mode because it doesn't have any headroom for overclocking or enough PCI Express supplementary power connectors.
