Come back from a couple of days away and my PC wont turn on. No fan, beep, or post at all. I put in a spare PSU and it spins the fan for a split second but then nothing. The good ol' paperclip in 16&17 test tells me both are dead. Thankfully I had another lying around and that at least gets it going. Sadly it's a modular Corsair CX430M and I have obviously put the unused (now needed) cables somewhere safe !

I have a Gigabyte GA-H97M-D3H with an i7-4790, 16GB ram, GTX1060 6GB, one Samsung 850 SSD, two WDGreen 1TB's and one Bluray DVD.

The calculators I find online say the CX430M should handle it with no problems but it wont boot with the 1060 plugged in and online reviews suggest they are best suited for plain business desktops.

Can anyone suggest something I should look out for ? It's been a while since I've needed a PSU. I'm not looking to spend $$$'s but don't want super-cheap either.

I've got a spare (Wellington) PSU rated 420W ... all the usual connectors but only 1 6-pin PCIE.

as always the best advice comes form youtube

I always use the outervision calculator - https://outervision.com/power-supply-calculator

A good 500W with 80+ gold or better or so would be best bet based on your spec.

something like these .. https://pricespy.co.nz/category.php?m=s323416000&o=produkt_pris_inkmoms

If you see one you like check if JohnyGuru (www.JonnyGURU.com) or other trusted source has done a review on it.

Back in the days of GPU mining, I bought a load of power supplies. In the end I settled on FSP because they were cheap and never failed. Can't say the same for the others - which were often a lot more expensive.

FSP are really underated in NZ .. some of the best units I have seen reviewed are FSP and when I was in the Server game we always used FSP for critical workloads.

A cooler master V750 would give you plenty of space for future proofing, they are modular as well. I have always used cooler master PSU and have never had any issues.

Ok, the JohnnyGuru site is fantastic, exactly what I needed thanks @GoranZ

So I've settled on either an EVGA 550 G2 for $183 at Computer Lounge or the Corsair HX750 V2 Platinum for $212 at Playtech.

But having read so much over the last 24 hours I'm confused as to why the Corsair CX430 cant handle it. Every site I find says it should work with no problems but the moment I plug the GTX1060 in the PC wont even switch on, no power, nothing. I remove the power and it runs perfectly.

Your right in that the CX430 should be OK .. my rough calculation says you need 400W and 25A on the 12V which it should deliver.

I myself have a 1060 running with I7-3770 and only a 500W fine.

The only things I can think of would be are you overclocking the i7-4790 and drawing a lot more power ?
Do you have the extra 6pin PCIe Connector attached or using a bad adaptor ?
Have you updated to latest BIOS on the GA-H97M-D3H as some of the fixes improve support for CPU and GPU ?
Any other cards or peripherals attached ?

It may just be the CX430 is not performing to its original potential

It could be your GPU thats faulty. I have two friends in the US, both had the same identical GPU (they were bothers) and about a year apart both had a fault where their PC would not turn on, it turns out the GPU had fried itself.

Have you got another machine you can test the GPU in to see if the problem follows it?
