Need help picking a PSU

Eastc93 · Feb 12, 2016

I currently have a Gold Cert Corsair CM450S 450W PSU, however after reading certain reviews for the graphics card I have on the way I'm worried the wattage isn't enough. Here is a list of my components:

PC

- Intel Core i5-6600 3.3GHz Quad-Core Processor
- MSI B150 PC Mate ATX LGA1151 Motherboard
- G.Skill Ripjaws V Series 16GB (2x8GB) DDR4-2400 Memory
- Kingston SSDNow V300 Series 128GB 2.5"
- Western Digital Caviar Blue 1TB 3.5" 7200RPM HD
- MSI NVIDIA GTX 970 Gaming Twin Frozr HDMI DVI-I DP Graphics Card (4GB, PCI Express, DDR5, 256 Bit)
- Cooler Master N300 ATX Mid Tower Case
- Corsair 450SM 450W 80+ Gold Certified ATX Power Supply

First question....how old is the power supply? If it's new'ish then it should be fine.

The second thing is that newer components are usually more efficient than older stuff.

I lost an 850W 80+ gold after 3 years but it was a big system and took several power failure hits.

If you can replace it with a nice 550W off Tier 1 or 2 you might have better piece of mind.

I like Seasonic models myself. EVGA G2 and XFX models are highly rated

Thanks a lot for your speedy response. Yeah the cost of my piece of mind was only £20 more. I went from the corsair to the EVGA Supernova 550w Gs Gold Cert fully mod - my original plan was to always go XFX but they all seem to be out of stock and have been since early Jan. I read lots of reviews on the Gs I just bought, there were 23 on Amazon, all 5* with good things to say

It's the best 550w PSU on the market based on the award winning Super Flower Leadex Gold series with a 7 year warranty.

550W G2 review.

Performance (40% of the final score) - you probably already know what I'm going to say here. Voltage regulation was excellent, averaging 0.9% in the hot box. No points deducted. Efficiency was a pass for Gold both times. No deduction. Ripple control was amazing, and probably the best I've ever seen, so definitely no deduction there. I saw no issues with anything else, so this unit gets a 10 here.

Functionality (20% of the final score) - this unit gets everything right. Even the CPU cable, which I thought was terrible on the 650W, is done right here today. Semi fanless mode works well, the manual is decent, we got lots of connectors to power anything a 550W unit should power, and the box came with more goodies than I tend to expect with such a small unit. 10.

Value (20% of the final score) - you can get one of these for $84.99 at Newegg right now. That's a fair bit for a unit this size these days, but as always EVGA is right at the bottom of the cost pile when it comes to 80 Plus Gold and full modularity. The nearest competition is their own 550W GS unit at one dollar more money. This is nuts. How are you making any money on these, EVGA? 10.

Build Quality (20% of the final score) - oh, snap... EVGA just got another perfect total score. There's nothing wrong with this unit. Nothing. 10.

So would you suggest the G2 over the Gs?

Dark Lord of Tech · Feb 12, 2016

YES IT'S MADE BY THE Best = Super Flower and a great 7 year warranty after you register it.

Dark Lord of Tech · Feb 12, 2016

The GS is only 5 year , G2 7 YEAR.

Eastc93 · Feb 12, 2016

How do you register it?

Dark Lord of Tech · Feb 12, 2016

At their site EVGA , takes a few minutes.

:lol:

:lol:

The best??? LOL! A group of some very good engineers? Yes. Amongst the best? Maybe. But the best? WOW!

But to stay on topic... I too would suggest the G2 over the GS if you're going to stick with EVGA.
