Can somebody recommend a power supply upgrade?

Hustey · Jun 23, 2015

Hi there,

I built my PC last year, but i didn't buy a graphics card. I used a gtx 650 card from an old PC with the plan to upgrade in the near future. So now i'm planning on buying the r9 390 or the gtx 970. I also want to overclock my CPU which is the i5 4690k. The power supply that I currently have is the corsair cx 600m. I've read that it's not the best power supply and that it isn't recommended for gaming computers and also overclocking.

I'm now thinking of upgrading the power supply, I think that 650w should be enough since i'm not planning on having two graphics cards - correct me if i'm wrong. So I wanted some advice on a 650 w power supply (Or other wattages) that will fit my needs. I also don't want to spend a tremendous amount of money on one, i'm looking at around £60. I've seen the Corsair RM - 650, for £60 on Amazon. Is that any good?

Thanks

BTW GTX 970 is better

Hustey :

- The R9 390 require a 650W PSU that can deliver 28Amps or more on its +12V rail and has 1 x 6-pin, 1 x 8-pin PCI Express power connectors. (8-pin usually come in 6+2 pin configuration. This is because there are cards, for example, the GTX 970 that require 2 x 6-pin connectors. So in that case, you can leave out the 2-pin and use the 6-pin alone, as the second 6-pin power connector.)

- The GTX 970 only require a 500W PSU that can deliver 28Amps or more on its +12V rail and has 2 x 6-pin PCI Express power connectors.

- The Antec TruePower Classic is a quality 650W 80+ Gold Certified PSU that can deliver 54Amps on its +12V rails combined and comes with 4 x 8-pin (6+2 pin configuration) PCI Express power connectors.

- Having all PCI Express power connectors as 8-pin is particularly handy, when in future, if you wish to upgrade to even higher GPU that may require 2 x 8-pin connectors. Example, the upcoming AMD's "FURY X" require 2 x 8-pin connectors.

- This PSU is certainly better than Corsair RM 650W and more than enough to power either the R9 390 or GTX 970 along with all other components in your rig.

- Comes with 5 years warranty.

Update:

Consider this quality 650W semi-modular, 80+ Bronze certified PSU that can deliver 53Amps on its +12V rail, comes with 4 x 8-pin (6+2) PCI Express power connectors, 5 year warranty and also compatible with Fractal Design Core 1500 (mATX):

- The Fractal Design Core 1500 (mATX) supports ATX PSUs up to 155 mm deep when using the primary bottom fan location; when not using this fan location longer PSUs can be used.

I recommend the above PSUs based on assumption that you don't use a case fan at the bottom of the case.

Latest & Final Update:

You can keep your bottom case fan in Fractal Design Core 1500 (mATX). Get this "Tier 1" quality 80+ Gold Certified Fully Modular PSU that can deliver 54Amps on its +12V rail, comes with 4 x 8-pin (6+2) PCI Express power connectors, 5 year warranty.

And most importantly fits in your case, which accepts PSUs upto 155mm in Length. This product dimensions - 86mm (H) x 150mm (W) x 150mm (L)

I would probably prefer to have a modular or semi modular PSU since the case that I have is micro atx. Thanks

If you want semi-modular, Than go with this one i linked earlier

http://uk.pcpartpicker.com/part/antec-power-supply-hcg620m

Hustey · Jun 23, 2015

Is 620 W enough to run the r9 390 as well as potentially overclocking both the i5 4690k and the r9 390?

turbopiki · Jun 23, 2015

Yes Antec HCG 620w is more than enough even if you OC. Antec HCG 620w has 48 amps on 12v rail.

r9 390 is r9 290 rebrand. System with R9 390 needs 31 amps on 12v rail. Wattage is not the crucial factor, how many amps are on 12v rail is

utgotye · Jun 23, 2015

Depends on the overclocks but better to be safe than sorry. Amps you are probably fine but Watts might come up short.

More amps and 100 more Watts for your OC.

http://uk.pcpartpicker.com/part/evga-power-supply-110b20750vr

Figure @ 4.0Ghz you're using in the 550W range. The tough part is figuring out how much your graphics overclock will add. The only thing I'm fairly sure of is that it will be more than we think.

turbopiki · Jun 23, 2015

utgotye :

How can you be okay with amps and not okay with wattage ? 1 amp is 12 watts. the difference between PSU with same wattage are that some have more amps on differente rails, but 12v rail is most important it powers CPU and GPU, other rail power thigs like fans and HDDs

utgotye · Jun 23, 2015

I can multiply. And those other rails are important because they do use power, however little. If he's planning on overclocking, we can't really determine how much he needs because every situation is different. So outside of giving him a ridiculous amount of extra room, there's no...sound...way of estimating how much he's going to need with any degree of certainty, especially considering, despite their rebranded nature, we don't know exactly how the 300 series cards will overclock.

turbopiki · Jun 23, 2015

You really think that hes usage will go up by 17 amps or more ? no way you can put that much power in CPU and GPU without frying it

utgotye · Jun 23, 2015

Realistically? Probably not, but I'd rather spend an extra $10 and never worry about it again.

I have actually got the fan space occupied at the bottom of the case. The CPU cooler I bought happened to be in the way of the side fan space. Which meant I had to use the bottom for an intake. So i don't really want to have to lose the bottom fan if possible. Which means anything above 155 mm isn't really suitable.

I would personally get an XFX 650W power supply or a Seasonic 620W power supply!
